Urban Pollution Of River Water Pollution Control Technology Research

With fast development of our country economy and acceleration of urbanization, the river contamination in our country cities is increasingly serious. The river water has seriously, the rivers environment has worsen, the rivers ecological equilibrium has gradually lost. The serious polluted status has directly affected urban enviroument around the rivers and development of city economy. Therefore, it is particular urgently to treat with the city river, especial to take water processing in the city river.In the city surrounding, river has been polluted, and the quality index of its water is lower than the national surface water IV standard, which is defined as "The city polluted rivers".Because complex situation of river water pollution and less research on government technology in river, it lacks research on water quality purification directly in riverway. At present, the treatment of polluted city river is generally focus water conservancy and hydrology.This paper has studied essential environment factor and the ecosystem structure of the rivers, and has discussed the merchanism of self-purification in city polluted rivers. After analyzed the reason that city rivers have been polluted, I summarizes the domestic and foreign research progress on each kind of polluted rivers water pollution control technology such as water quality purification and the ecology restores and so on. Has analyzed that characteristics of each kind of technical and serviceable to different types of rivers.After narration, this paper has discussed the strongpoint or disadvantage of microorganism repair technology emphatically, as well as on the feasibility to utilize this technology in our polluted city rivers.At the same time, paper proposed to use comprehensive water pollution control method with biological-ecology repair primarily to the polluted city rivers, and designed integration plan of synthesis contamination control technology on the polluted city rivers.In order to seek technologis of water qualitity purification in the polluted city river, we have carried on the project experiment revitalization of Xiba River. The Xiba River locates Kunming City, is one of 22 rivers which inpour to Dian Chi Lake, it has polluted severely. Experiment is carried out bioremediation on the downstream segment of Xiba River by the Aqua Clean ACF32. The result showed that the Aqua Clean ACF32 can do away with the odors, reduce the organic pollutant and turbidity with the higher rate, BOD5, COD, TN, TP, turbidity clearance respectively is 33% ~ 58%, 13% - 48%, 5% - 42%, 12% ~ 46%, 24% ~ 90%. It can promote polluted water body to evolve toward the positive ecosystem, make water body revitalized. The experiment had initially proven the feasibility and the efficiency of synthesis contamination control method with the biological-ecology repair primarily. It provides the beneficial reference for treatment on our polluted city rivers.Hie research goal of present paper lies in: summarizes the research and the practical experience of treatment and the ecology restores on polluted rivers from domestic or external. Through to the research on rivers water pollution control technology, makes every effort to seek to the polluted city rivers water pollution control method with economical, energy conservation, high-powered characteristic and conforms to the ecology protection request simultaneously.
