| Will not dissolve in the solvent of water into the waste water, the waste water of solute dissolved in the solvent, and then use relative density difference with water soluble agent, to isolate the solvent extraction agent, butyl acetate, benzene and N - 503 devices such as pulse sieve plate tower, centrifugal extraction take machines such as wastewater containing phenol adsorption (packet containing ion exchange) will waste water with solid adsorbent, dissolved organic in the wastewater or no machine physical adsorption on the adsorbent
Learn from housing urban and rural development, in 2014 to increase the intensity of urban sewage treatment work appraisal, by the end of 2015 to achieve the goal of every county has a sewage treatment plant. In 2014 will continue to strengthen quality supervision work, promote the water quality standard. At the same time, the implementation of the regulations on the urban drainage and sewage treatment, planning for the construction of complete national city drains facilities.
Processing the waste water of adsorbent is activated carbon, coal slag, soil adsorption tower, such as dyeing, pigment wastewater regeneration device, but also the adsorption of phenol, mercury, chromium, cyanide, and in addition to color, smell, taste, etc for depth treatment of urban sewage treatment process debugging method at present, the importance of urban sewage treatment plant process debugging is not widely known and accepted, many sewage plant to process after the completion of the commissioning, this leads to either run up, or to run water quality can not meet the design requirements, the phenomenon of the high cost. Membrane separation of the exhibition is a bright spot, whether the use of the use of drinking water or sewage, view is based on a hot afternoon wool spinning waste water extraction.
Distance from the last time have been to Shanghai in 78, though a bit long, but have been to appear to have no novelty. That Shanghai is very hot a few days, less green metropolis like bamboo steamer, to be honest, I have lose goodwill in the modern metropolis, the eyes of high-rise buildings has long been insensitive, just feel as crowded, in a hurry.
Then go to nanjing on Sunday, all the way on the high-speed rail, all could not see the blue sky, the sky is grey, it seems now the air pollution than imagination!
In order to solve the problem of heat source shortage, jinan is exploring multi-channel heating, one using the sewage heating technology, recently has been on the agenda. This technology is expected to be combined with wastewater treatment with three factory pioneered in riverside district local area of the test points.
3. The essence of activated sludge cultivation activated sludge is in a period of time, through certain means, make the processing system produces and accumulated a certain amount of microbes, its means of cultivation are continuous and intermittent. 2.3.1. Continuous training: continuous culture refers to the continuous feed, continuous water under the situation of activated sludge cultivation mode. Choose this kind of training mode condition is to have enough water, this water inflow can satisfy a into the water pump for at least 24 hours of the water, even the type of training is to develop the advantages of short time
Microorganism domesticated time needed for short. Their specific operation method is determined according to the size of the inflow into the water pump on the Numbers and number of sets of biological pool open, grill machine, the grit chamber, the second pond, open, open the reflux pump (if there is inside the reflux pump, be unable to undo), back flow control in more than 100%, dissolved oxygen aeration zone is greater than 2 mg/l, biological pool average velocity of not less than 0.3 m/s, the absolute velocity of not less than 0.2 m/s, continuous operation. Every day in the process, the determination of the water quality indexes and control parameters. When the sv % above 10%, activated sludge cultivation is successful, the effluent bod5, ss, cod, and other general indicators can meet the design requirements.
Indeed, environmental protection class blog is really very few, the blog at that time also is said to be the first environmental protection engineering blog, if content of main introduction articles or reproduced some environmental protection technology, engineering and environmental information images, is a very good technical communication platforms! Just feel, in fact, to see whether the technical aspects of the article, on the Internet how much? A lot of professional environmental protection website information on the BBS to see them all
EWTS electrochemical wastewater treatment system is three sheng environmental technology USES electricity the electrical polarization ionization chemical sewage treatment technology. The characteristics of the system: 1. Don't need to add chemicals, namely USES the "subtraction" way to deal with the sewage; 2. The equipment capacity big, cover an area of an area small; 3. Only apply to electrical energy, low operation cost, energy conservation and low consumption; 4. With composite electrode, thus preventing passivation; 5. Automatic mineralization degree is high, easy to operate, easy to monitor and control maintenance.
To ensure the effective work of debugging. Sewage process debugging anomaly judgment by default classified the 2008-08-06 18:43:41 reading 143 comments 1 font size: medium A scum, foam, biochemical system causes and countermeasures of biochemical pond scum causes: from the abnormal metabolism of activated sludge system, may also be A surface of inorganic particles. The second pond scum: from the scum of the biochemical system, the second pond sludge floating, the second pond after activated sludge nitrification hypoxia serious cause anaerobic sludge floating. Bubble formation: water viscosity increased, mainly due to: high organic matter content, water aeration activated sludge mixture aging, water containing excessive amounts of detergent or surfactant, death bacteria expansion, etc. Bubble sort: 1. Tan: activated sludge aging, sludge aging and disintegration, suspended in the mixture, attached to the foam, lead to prolonged bubble burst, form scum. 2. A film: oxygen to activated sludge and anaerobic reaction. In addition to analysis if there is any black inorganic substances into the water. 3. White: sticky not easily broken bubble, colour and lustre is bright white, piling up sex is good, the reason is the water load is too high; Viscous but easily broken, for old white color and accumulation is poor, only partial accumulation, cause excessive aeration;
Themselves don't have the patience to blog reading technical articles, so want to build a kan about sex than environmental blog!!!! In the practice of the environmental protection industry experience and feeling and related economic life, keep the original. Today, what is IT, PCB, law and so on people's living conditions are spread in the network infinite, but how many people to understand the status of the environmental protection engineering in this industry? More so, than kan, less serious orthodox technology, wrong doesn't matter, anyway, oneself also little aura, no all fear no more, no blog! Might as well some more thoughts, if therefore attract like-minded or make wine disease phase flow with pleasure so much the better!
The city of nanjing is very good, a railway station is a large exhibition shore, for waiting intermittent relax, feeling is not as nervous as in other parts of the railway station in a hurry. Buttonwood is all the more chic, on the edge of the city streets, I believe in the hot sun, popular with the public, not just visit is bright, the two days the sky yellow fog haze, low visibility, very strange. Reported main reason is that the suburbs farmers caused by straw burning, watching the news today, found that wuhan and hefei and other places these days the sky is so, murphy around farmers have JieGan (straw) and up? Old tradition to burn for hundreds of years, and now finally burn out.
Bird migration route here is located in east Asia, Australia, found a black mouth side of rare and endangered birds crested terns, pelican, vervet spoonbills, spoon sandpiper and so on more than 50, waterbirds in number more than 20000 each year, the number of water birds migrating down more than 50000, is a treasure trove of typical wetland biodiversity. Journey throughout the year for different birds and transformation of the wetland landscape and colorful ecological picture scroll, becomes the multitudinous birding, take the first choice for bird lovers.
The glacier retreat with water shortages
The United Nations environment programme (unep), according to a report due to climate change (climate change) and the excessive use of water, the Himalayan glaciers two-thirds are gradually retreat. Glacier is the birthplace of many important rivers, such as the Yangtze river, the Ganges and Brahmaputra, the Indus river and so on. Glacier retreat may lead to more than 1 billion people lack water.
Grill machine, the grit chamber, began after aeration biological pool filled with water, stop the water at the same time, the time measuring biological pool, when cod, ss are much smaller than water stop aeration, settling into the water again after 2 hours, excluding the solution at the same time. In the process of the determination of water quality indexes and control parameters and complete marked with continuous training. 2.4. The purpose of the activated sludge domesticated domesticated is choice to adapt to the actual water quality situation of microbes, eliminate useless microbes, to have the function of nitrogen and phosphorus processing work of art, through domestication nitrifying bacteria, denitrifying bacteria, phosphorus accumulating bacteria become advantage bacterium group.
The normal operation of the specific approach is to first maintain process, strictly control process control parameters, then do the YanYangChi control below 0.1 mg/l, in anoxic pool under control in 0.5 mg/l, in the aerobic pool control in 2 to 3 mg/l, aerobic pond aeration time not less than 5 hours, the reflux ratio 50% ~ 100%, the reflux ratio 200% ~ 300%, and a day rule out nissan mud 30% ~ 50% of the amount of residual sludge. In the process, test every day in and out of the water quality index, until the water each index meet the design requirements. 2.5. The determination of process control parameters in the design of process control parameters is determined in the prediction of water quantity, water quality conditions, the actual operation of the sewage plant is different on the water quality and design often, therefore, must according to the actual water quality situation to determine the appropriate process control parameters, so as to ensure the normal continuity for running and pulling at the same time as far as possible, reduce the energy consumption of the water quality standard.
In the 1950 s, the Himalayan region of embankment mountain and glacier is covered with a thick layer of ice.
In 2007, under the same observation point of cut wave peaks tower, due to climate warming, the ice has large fade. Xiamen ring and hydraulic technology co., LTD focus on sewage wastewater treatment, water reuse, outdoor water purification equipment, the recycling of the waste gas processing and waste reduction. The company equipment is suitable for various use may cause environmental pollution of industry, such as: electroplating, printed circuit board, textile printing and dyeing, leather, pharmaceutical, mining, food processing, food, municipal (life), slaughtering, aquaculture, chemical industry, oil, etc.
Another Angle of the 2007 mu mountain landscape, as global temperatures rise, some peaks of ice has subsided more than 100 meters, the melting of the ice particularly at low altitudes.
Company and guangzhou green by similar nature, but luck is much better than the latter, just be informal netizens revealed that very few sites include the post now, such as newspaper or television media do not report formally. Shows the event of emergency, and social pr did a great job!
Although online also contend that this is the net friend framed, but same as environmental practitioners, true not true as early as in the heart has its own public opinion.
Especially, this kind of environmental protection in the process of the company's business operation, recycling produces large profits, it must think method to recycle. This is the promotion of the circular economy, from this aspect, it is the pioneer of circular economy. It is, however, the process of recycling, will also produce a lot of waste, waste water. These still need to deal with. And handling, you need a lot of money. At this point, it and other chemical manufacturing nothing different. Don't look at it hangs the guise of an environmental two words.
Cut short.
"As a member of the city, our tiny as particles." But if the post of hair can cause some attention, also pretty interesting. And can and a group of people, concern the destiny of the waters, and also feel into a city, make life more fulfilling.
Bohai bay oil field oil spill accidents
3, blue star cleaning in make water recycle and medicament is quite strong, it represents the industrial water treatment engineering and pharmaceutical stocks, but a poor, disappoint with water treatment plot I found it, a month after the intervention in early November to joint sleeve. Not the sigh, China's industrial water treatment market is not wide, but actually there are several companies can a few hold the wheel is like a water world? Can absorb up to the environmental protection company of environmental protection engineering practitioners can when can appear a few can be rely on the tree?
On June 4, 17, cnooc, conocophillips, cooperation with the United States project of bohai sea platform B and C in the penglai 19-3 areas platform has oil spills. But until two months later, on July 5, the state oceanic administration was reported to the society held a conference preliminary findings. Survey by the state oceanic administration, which is developed by homework Fang Kang thin oil companies do STH without authorization changes with design scheme to the responsibility of the accident, which caused significant pollution to the Marine environment. It said that the spill should assume all responsibility by operators, China, a maximum fine of $200000 on it.
200000 yuan has been widely questioned "punishment" is too light. Hebei LeTing, yantai, shandong province, fishermen farmed seafood because of pollution and a large number of death, the conocophillips in court, but the civil compensation in sight.
Review: a extends for half a year is still not a clear process the results of pollution accident. Compared with the BP in the gulf of Mexico oil spill, cnooc and conocophillips seem to be very lucky and arrogance, but who's going to buy sheet for bohai sea pollution? Who for the victims of the fishermen rights? Environmental compensation law should be how to improve?
Seven: drought and desertification
Since the 1970 s, the area of the severe drought region on earth almost doubled, the national center for atmospheric research scientists said global warming is the culprit.
A UN study showed that caused 41% of global climate warming, dry areas of land degradation, global desert area is gradually expanding.

Typical city sewage treatment process and the use of detailed information
screening
Large solid residues (plastic, cloth, paper) first by mechanical sieve to remove. The traditional examination method, in order to protect the downstream operation only remove the solid material is bigger (& gt; 25 to 30 mm). Now, more refined picture (6 mm sieve) is usually used to remove small inert solid. Keep materials (' matching ') usually wash and remove debris, and then compressed adopted there landfills or incinerators.
