Bad trial pollution of water resources and water pollution and sewage treatment process
Edited:HuanChuang technology   Date:2014-2-20 10:55:55
Bad trial pollution of water resources and water pollution and sewage treatment process Water resources in the process of use due to lost the use value was abandoned outside, the receiving waters are affected in various forms; and the water is called the wastewater. According to different sources, the wastewater can be divided into two major categories of life sewage and industrial waste water sewage is generated by people in daily life waste water, industrial waste water is the discharge of waste water in the process of industrial production. Common industrial wastewater treatment, food industry wastewater treatment 1, 2, 3 industrial wastewater treatment of pulp and paper, light industrial wastewater treatment, 4, 5 textile industrial wastewater treatment, oil refining and petrochemical wastewater treatment 6, 7, coal chemical industrial wastewater treatment of industrial wastewater treatment 8, fabricated metal products processing wastewater treatment waste water sources and characteristics Since last year, the news of the timber price has spread in the industry, from the point of view of the imbalance between supply and demand analysis, it is not difficult to understand the situation. Due to the natural increase the cost of raw materials, as well as the social labor costs increased year by year, floor price increases seem inevitable. Sewage treatment method classification method is the basic principle of unit technology basic physical physical or mechanical separation process of filtration, sedimentation, centrifugal separation, surface chemical method of adding chemicals react with pests in sewage quality conversion process of neutralization, oxidation, reduction, decomposition, coagulation and precipitation change to learn physical chemistry such as gas stripping method, the physical and chemical separation process, blow off, adsorption, extraction, ion exchange, electrolysis electrodialysis, reverse osmosis and other biological method, microorganisms in the wastewater oxidation to have operations on the machine, the metabolism of decomposition process of activated sludge, biological filter, biological rotating disc, oxygen pond, anaerobic the elimination methods of chemical methods of wastewater treatment such as table 2 principle of equipment and materials processing object coagulation to glue dosing in the turbid liquid electrolytic, condensed water colloidal substances, divide the sum of water coagulant aluminum sulfate, alum, polyaluminium chloride, ferrous sulfur acid, ferric chloride and other oily wastewater, dyeing wastewater, gas station wastewater, wool washing waste water neutralization and acid and alkali Due to the quality of people's life demand is higher and higher, the floor should not only practical, but also has the beautiful sex, so it is more businesses will do some innovation breakthrough in appearance texture. In recent years, in addition to beautiful texture, personality, index of green environmental protection into the more consumers pay attention to. In addition, with the improvement of the quality of life, green environmental protection become fashion trends in the flooring industry, wood species no big change, product update cycle is longer, usually also will launch a new series of the year. 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. Mainly used in the source water, the national nature reserve; Snow mountain rivers, the Brahmaputra stretching over Ⅱ class - mainly suitable for centralized, the surface water source protection zones for domestic and drinking water, rare and precious raw water habitats, shrimp, spawning grounds, the larvae of larval feeding, etc.; Thousand island lake parts of the Yangtze river Ⅲ class, mainly is suitable for the table of centralized drinking water, ground water level reserve, shrimp, wintering and migration channel, aquaculture and other fishing areas and area; Parts of the middle and lower reaches of the Yangtze river Yellow River Ⅳ class, mainly is suitable for the general industrial water area and not direct contact with human body of recreational water area; V class, mainly is suitable for the agricultural water area and the general landscape request waters; Bad Ⅴ class - has lost the basic function of water body, are seriously polluted. Dianchi lake chaohu (62.5%) (62.5%) (34.1%) of the red tide algae in taihu lake water eutrophication: under the influence of human activity, nitrogen, phosphorus and other nutrients needed for the biological a lot into the slow flow water bodies such as lakes, estuaries, bay, cause rapid reproduction, algae and other plankton decrease dissolved oxygen of water, water quality deterioration, fish and other creatures of the phenomenon of death. Seventh national conference on environmental protection held in Beijing on December 20, the environment around and part of the central enterprises and signing of the "twelfth five-year" main pollutant total emission reduction target responsibility, high-profile "national environmental protection" twelfth five-year "plan" officially released. 21 morning, its closure. Environment minister zhou shengxian for the meeting summary. Zhou shengxian, stressed that the grade environmental protection departments should earnestly study and implement the conference spirit and vice premier li keqiang's important speech, insist on developing protection and development in the protection, actively explore new roads, environmental protection and solve scientific development and outstanding environmental problems that harm people's health, create a new situation of environmental protection work in an all-round way. Comments: "planning" let us see the hope, let people breathe fresh air, drink clean water, safe food to eat, to become the most important works at all levels of the government, China's environmental protection work should comply with the people look forward to, don't again to make way for the economic development. 4, xia ke main business is recycling ingredients available in textile industry, on polyester and other waste plastic division. In today's, garbage, and many industrial waste recycling has become a hot property, its shares rise soon, and than mainstream only eliminate the pollution of the environmental protection industry, recycling also can create value, most circular economy effect, the natural prospects are very broad. The most classic is listed in Hong Kong, shenzhen dongjiang environmental protection, only more than eight years, recycling electronics factory waste water of heavy metal and organic solvents have let Mr. Yang to squeeze into the list of Forbes to be China's potential. Above techno-enabled places each have advantages and disadvantages of several major environmental protection, if taking advantages of them, namely: warm and deep discussion (sentiment + veteran) + abundance of data download + powerful BBS, abundant financial resources, it is perfect. But there is perfect thing in the world is hard to find, if can complement each other, flowers is very good also. 1. Sewage treatment process, the structure, function and the name of the relationship. 2. The sewage source and water quality, water quantity change law of drainage water quality standards. 3. The system basic knowledge and the technical parameters of main equipment. 4. The purpose of the main line, all kinds of requirements for opening and closing of the gate and the influence of the process. 5. Sewage treatment system security technology operating rules. 2, operation asked (should) 1. The various process related equipment, pipe gate operation method and the common fault of the sewage treatment. 2. The observation and determination of the operation of the biochemical treatment structures. 3. To identify the quality of the activated sludge, reasonable control reflux sludge quantity and timely; A moderate amount of discharge of surplus sludge. 4. Master the grit chamber, sedimentation tank platoon slag, mud regular and timely discharge. 5. Grasp the sewage pool digester general rule, temperature, stirring and outdated batching emissions of the sludge. 6. The field test instrument observation and use. Wildlife disappear Professional committee of the UN's intergovernmental panel on climate change (IPCC) report points out: if the earth's average temperature, 1.5 ~ 2.5 ℃ higher than 1990, is about 20 ~ 30% of plants and animals will face extinction; If the temperature rise of 3.5 degrees Celsius above, 40% to 70% of species face extinction. Climate change has become the greatest threat to coral reefs, 19% of the world's coral reefs have disappeared. After warming degree c temperature rise, at one time, throughout the year will have half a year in the Arctic Circle without ice state, and who normally do not know for what the south Atlantic hurricane coast region will suffer from the hurricane hit, residents in the western United States will face serious long-term drought.
