“As Xi’an, Shaanxi Province
Environmental protection Council approved the “county sewage treatment plant construction issues of ecological research projects,” the whole of Shaanxi is watching this one A standard week to sewage treatment plant. Now, the project finally completed. “Beijing Century Oceanside Qinhong Xing Technology Co., Ltd. General Manager, said excitedly. After intense construction, overcome many difficulties, Zhouzhi County, Shaanxi Province, ecological wastewater treatment plant recently completed.” I have a dream, to build an appropriate national conditions of China sewage treatment plant. “In the Qin macro view, easy to build sewage treatment plants, and ecological wastewater treatment plant hard to build. He believed that a city’s ecological wastewater treatment plant to achieve the four levels of objectives: the first level, less investment, low running costs , good effect; the second level, through the sewage sludge treatment, recycling of resources; third level, the formation of decontamination water treatment plant operators other than the variety of eco-industries; the fourth level, build garden eco-sewage treatment plant.
Clearly established why the project can be a profit? Select a low operating cost, high economic return of technology journalists see Qin Wang, he had just returned from a week to Beijing. Over the past 9 months, Qin Wang sits weeks, personally directing the project. Zhou Zhinan by Qinling, north near Wei, named after the mountain Qushui fold, since ancient times “golden weeks” in the world, is the most important sources of drinking water in Xi’an, the Xi’an is the only state-level ecological demonstration counties. Good ecological
Environment Is the biggest capital weeks, so the sewage treatment plant technology choices, the weeks and extra weight to the “ecology” of this factor, the final choice of the constructed wetland technology. In the management of municipal wastewater, improve local water quality, ease the downstream river water environment pressure, also through constructed wetlands and diverse plant system and surrounding landscape open channels, water park and other construction projects complement each other to create an “ecological wetland” . Zhouzhi County sewage treatment plant ecology total area of 73 acres, a capacity of 11,000 tons / day. During the test run the project is completed, the actual entering and leaving the water quality monitoring results indicate that all targets were achieved, “Municipal Wastewater Treatment Plant Pollutant Emission Standards” (GB18918-2002) 1 A class of emission standards. Among wetland nitrogen and phosphorus treatment effect is very obvious. Qin Wang said, weeks and sewage treatment plant running costs of about 0.2 yuan / ton, the local sewage treatment fee of 0.3 yuan / ton, coupled with financial subsidies to 0.8 yuan / ton, excluding wages, this year the sewage treatment plant also 280 million from profits. Why is this Project can be built on a clear profit? This is obviously a lot of places, “money plant, money operations,” the situation in the contrast. The reason for weeks to choose a low operating cost, high economic return of technology?? Constructed wetland wastewater treatment technology.
Surface similar, but in fact open a drastic treat all sorts of possible
Water Pollution The problem is artificial wetland construction, and control operation, and the swamp is similar to the ground, sewage, sludge and controlled dosing into the wet ground by the artificial construction of sewage and sludge in the direction of flow along a certain course, the main use of soil, artificial medium, plants, microorganisms physical, chemical, biological triple synergy of sewage sludge treatment of a technology. This includes the internal structure of the system, active media, media systems, plant systems, water distribution system, drainage system, anti-blocking system, the winter run antifreeze system and other key technologies. Qin Wang’s first corrected illusion, “Building a wetland is not Wage Keng, kind of a little reed that simple. Apparently similar wetlands, but in fact there is big difference, which use a variety of technology.” 10 Spring, Oceanside century of painstaking research company wetlands, through the unremitting efforts, and now has six patents and more than 30 proprietary technology, breakthrough antifreeze, anti-blocking and other core technologies for different types of sewage, the establishment of a variety of artificial wetland treatment mode. Qin Wang in the eyes of constructed wetlands to treat open water pollution problems may arise, for a wide range. Up to now, Beijing Century Oceanside company on wetland sewage treatment project involves municipal sewage treatment, industrial wastewater treatment, aquaculture wastewater treatment, watershed management, ecological landscape construction and so on. Largest is 1.4 billion investment in Xi’an: coax exhausted? Yi? Yu? Aung chant that? still can not meet? Ulterior Xuehuang Jun? Biao?? Square kilometers; the smallest works in Beijing Fengtai Bridge Plant can process 100 tons of domestic sewage Constructed Wetland Treatment Project.
Constructed wetlands can survive the winter it? Flexible use of technology integration, a breakthrough high-density, high-latitude limit had a view of artificial wetlands in the north is not suitable for promotion, because of low winter temperatures, can not function properly. But Oceanside Beijing Century Technology Co., Ltd. in Fuxin City, Liaoning Province, the construction of swine wastewater and sewage treatment works constructed wetlands has been a continuous and stable operation for more than 3 years. Is located in Fuxin, northeast of the winter is very cold, artificial wetlands can survive the winter it? Company vice president Li Yuan original smiled and replied, in fact, like aquatic plants and general plant roots in winter is still alive. “Surface is the thick ice, ice is still under water flow, we are using ice sheet effects, ensure the normal operation of the sewage treatment plant in winter.” Qin Hong said: “The project runs, the results make them the ideal water depth deeply felt the benefits of this technology. ” This project involved Qinghemen Fuxin Park covers an area of 400 mu Hexi farming, pig rearing technology of using water will, more than 300 tons of daily discharge of wastewater. Project capacity is 300 tons of pig waste / day, sewage 1700 tons / day, nearly 4,000 of Fuxin City Culture Park, a large scale (field, household) and a positive example for pollution control. In order to grasp the constructed wetland technology, Qin Wang during their independent research and development, it is also “go, please come in” approach to carry out exchanges with foreign enterprises
Cooperation
. In 2001, Qin Wang and a U.S. company on technical cooperation, the other harsh conditions for talks. The company in Shanxi breeding through artificial wetland wastewater treatment, but without success. Americans do not succeed, but Qin Wang and his team have Zhuomo Tou mystery of artificial wetlands, “our success is the integration of science and technology carried out.” Qin Wang particular emphasis on integration, precisely because of the flexible use of technology integration, Century Sid wetland technology breakthrough in the high concentration of water, limit high-latitude areas, treatment of industrial wastewater and sewage treatment both worlds. “We made every
