Study on Water Quality Control in the Reservoir Retainning Water Initial Stage

Water resources have become contemporary economy society development of importance strategy resources. Our country face a problem, that is people many, water little, water dirty , economizing water is a basic national policies of our country. For betterly propping up economy society keep on high speed development, as economizing water, we must find the new source of water, therefore, science using of water resources have become the focal point of water business. Study on how to achieve the water quality of the new reservoir to meet water quality requirements, have very obvious of society performance and economy performance, in the region of lack water resourse.This text summarized the present situation of study on water quality control in the reservoir retainning water initial stage in domestic and dbroad. The text reached the initial water quality rediction and control measures of the reservoir, constructed in the region of frequent human activities, and having a higher ratio of inundated area and annual runoff in the area , by the living project-Huzhou Laohutan reservoir.The article main contents include:1, After read domestic and international concerning cultural, I showed the present situation of Study on water quality control in the reservoir retainning water initial stage in domestic and dbroad. At the same time, analysis the situationg of lack water resourse and the initial water quality of the reservoir in the South China , stangby Zhejiang province. At last, I telled the importance and meaning of Study on water quality control in the reservoir retainning water initial stage.2, Taking Huzhou Laohutan reservoir for example,I combed the normal regulations of the water quality forecast of reservoir.I reached the method of controlling the water quality of reservoir , that had a higner Storage capacity factor, in the mound region ,by taking the internal sources of pollution managing as the focal point. 3, After contrasted the main factors amount of water environmental capacity with those Calculated , that affectting the reservoir water quality ,I reached the measures of controlling non-point source pollutants and reservoir source pollutants.4, According to the determined result of reservoir water quality inretainning water initial stage, I checked the rationality of the measures.5,I summarized the result of study on water quality control in thereservoir retainning water initial stage, then I looked forword the future about the study on controlling the reservoir inside source pollutants and outside pollutants.
