Application Research On Black Odor Water Treatment Technology In Zuogan Canal Of Yuhu District, Xiangtan City

One of the major characteristics of existing cities in China is to build them according to the local water environment,and the sensory degrees of water in the city become the image brand of the city directly.With the rapid development of social economy and urbanization,the vurban population rose sharply and urban pollution emissions increased dramatically.At the same time,because of the relative lag of city environmental protection infrastructure construction,and pollution control levels far less than the speed of economic and social development,a large amount of pollutants in the form of sewage,garbage,precipitation and runoff is produced and entered into the city,leading to the deterioration of the urban water environment quality.Some urban rivers have even become the drain ditch of urban sewage,forming black and smelly water bodies.Due to years of disrepair,left main canal in Yuhu District of Xiangtan City have been silted up to a few meters,leading the channel stinking and the surrounding people complaining.In this paper,the project of black and smelly water treatment engineering of the left main canal is designed.By carrying out the comprehensive management of the water environment,soil environment and ecological environment of the left main canal basin,the treatment scheme of the black and smelly water in the left main canal is put forward,which includes the point source pollution and non-point source pollution control engineering,endogenous pollution control engineering,and ecological water system construction project.The four step improvement steps are put forward.By dredging and decontamination,the surrounding environment Yuhu District will be beautified,greatly improving the people's living environment.After the project construction,the flood control and drainage capability of left main canal in Changcheng Township can be greatly improved.Also,the image of the area and the infrastructure construction in Xiangtan city can be improved and the living environment of urban residents can be optimized,which is a construction project that the people of Xiangtan city are looking forward to and support for.It is of very significant social benefits and environmental benefits.
