Experts pointed out that the deteriorating ecological environment, make people realize the importance of environmental protection, and the ability to keep your family healthy at the same time, for a green earth. There is need to have asked, and environmental protection has become the main products of the brand floor, many businesses showed small make up a detailed brochure product performance, and said, the green environmental protection will become the main development direction in the future. In recent years, global warming in the arctic region has led to glacier significantly changes, atmosphere, ocean, etc. According to the national centre for scientific research data for scientific research shows that: in the past 20 years, the arctic ice cap area decreased by 40%, average thickness from 3 m to 1.5 m.
Sewage treatment process the first water amount is larger, according to local site condition, oil separation (adjustable) is proposed, underground integrated biochemical pool, pool aqua tendril advanced oxidation pond process for processing. First canteen wastewater, septic tank effluent and office building water mixing wastewater points don't early by separation tank and heavy regulation pool skim oil wastewater and large particles of impurities, and then flows into the biochemical pool under integration. In the processing units, wastewater by early sink nitrification and denitrification, and denitrification, anaerobic aerobic phosphorus, aeration to remove organic pollution, the secondary precipitation after removing most of the pollutants, the effluent discharged into the water near the pond, sewage to make use of the pool depth processing. Decorate in the pool in the aqua tendril ecological base filler, and plant all kinds of aquatic plants in the pond, set up the fountain, and build a good aquatic habitat. As an important part of landscape construction and improve the company's cultural grade and company image.
Sludge artificial regulation pool underground integrated biochemical pool of pickup aqua tendril senior pan toilet wastewater oxidation pond canteen waste water, building waste water separation tank rubber co., LTD. Sewage treatment engineering of some factory second water volume is small, but the pollution concentration is higher, but biological sex is good. The proposed grid - underground aeration tank - artificial wetland treatment process. Septic tank effluent by first grille out large particles of impurities, and then enter the aerobic aeration tank to remove most of the organic pollution, wastewater by liquid level controller control intermittent conveying sewage pumps to artificial wetland and artificial wetland can realize alternating wet, dry run, sewage into the constructed wetland, the wetland microbial group and combination of wetland plant developed root system, the N, P and organic pollution is broken down or absorption, the purification of the sewage achieve the ultimate. Process is as follows: the third point for the bathroom water, water temperature may be on the high side, so must consider to adjust cooling, and raw material processing. Considering the location of the point, sewage pump intermittent transfering septic tank effluent grille underground aeration tank artificial wetland rubber co., LTD. Sewage treatment plant project in oil tank has moved the location of the construction of concrete pool, the east river water directly into the factory. Treatment technology for the grating - basin - SBR pool - out of the Wells.
In the arctic ocean contains billions of tons of methane, at least if the methane is released in full and into the atmosphere, and will to the living things on the earth and environment devastating impact. When arctic sea ice cover, the large amounts of methane storage in permafrost, permafrost melts, the methane will be released back into the atmosphere.
The miracle of coral
In our eyes, Queensland, in Australia is synonymous with the Great Barrier Reef. Here, the smallest coral has created one of the greatest natural wonders, in the bottom of the sea built more than 2000 kilometers of the brainpower-computer Joan floor. Here is all the world's largest coral growing region, is also the only visible reefs, more than 350 kinds of corals, color, gorgeous, it is no wonder that australians to boast, this is the eighth wonder of the world.
Wastewater collected by drainage pipe network, into the sewage treatment part, through the grid to remove large suspended solid content. At the beginning of water into the flat again streaming pond, early in the pond, the removal of a small number of BOD5, most of the suspended solids precipitation sludge formation, under the weight of the pipe network to collect into the sludge concentration pool. At the beginning of the waste water after the pond, and then through the aeration tank, the surface aeration, adding the suspended packing system is stable, live sex sludge removing most of the part of BOD5 and SS. The waste water into the pond, further removal of BOD5 and SS. The drainage standard. Two parts of the pond sludge circumfluence, flow to the aeration tank for sludge inoculation, excess sludge to the sludge concentration pool, at the beginning of the pond, and the second pond, the mixed sludge concentration, and then enter the subsequent processing (outbound or burning).
In addition to the coral, here or hundreds of thousands of fish habitats, birds, turtles and whales have, is also the most like dolphins playing place. The Great Barrier Reef off home to about 1500 species of tropical Marine fish, 4000 kinds of acanthosis animals and mollusks, many of them are endangered species in the world.
