Application Research Of WOSC Combination Technologyin The Treatment Of Rivers Polluted Water

With the rapid development of economy of Pearl River Delta 、 the process of industrialization continues to accelerate、and the rapid population growth,Water pollution has become one of the major problems in our province.A lot of life, production wastewater and waste not treated directly into the river, causing serious water pollution, resulting in the water black smelly, eutrophication, resulting in ecological damage at the same time, seriously affecting the residents of life and physical and mental health. Therefore, the research on river pollution control technology is imminent, and also have important significance.In this study, we used the IBC microbial preparation as the main, supplemented by sewage interception(government), grid physical treatment、artificial oxygen、aquatic animals and plants, to build a restoration of the ecological balance system of WOSC Combined Bioremediation Technology, which not only has the role of cutting sediment can also degrade pollutants, so that the pollution of water purification. The Jiu Cun Yong pollution water test,examines the IBC microbial agents on the creek water pollution control effect on the strengthening mechanism, and in Jiu Cun Yong ecological restoration of polluted water engineering is verified. The contents and conclusions are as follows:(1) IBC microbial preparation for Jiu Cun Yong pollution water test. The results showed that adding microbial agents IBC can effectively remove organic pollutants in water,significant effect, COD、NH3-N and TP were the highest removal rate were 62%、78% and75%. Meanwhile, the activity of microorganism also increased significantly, and the activity of indigenous microorganism was significantly improved.(2) WOSC combination of ecological restoration technology in Foshan Nanhai Dali Zhen Jiu Cun Yong engineering verification, in actual creek restoration project, take to goodgovernance. In this paper, COD、NH3-N、BOD and TP were selected as the main indexes of the polluted water body. Early after six months after the operation, the water dissolved oxygen maintained at about 3 mg·L-1, the average degradation of COD、NH3-N、TP and BOD rate of47.1%、54.30%、38.1% and 58.4%, Creek black odor basically eliminated, water purification.Late after three months of operation, the main indicators of changes in water pollution and stable, and basic maintenance of above class V water quality standards for surface water.(3) WOSC combination technology of ecological restoration in Jiu Cun Yong water pollution treatment project shows that, the creek black smelly and good treatment effect, but also save investment,small factors,under the current severe water pollution of the environment,the technology in rivers, lakes and other water pollution governance have good marketprospects.
