Study On Water Quality Prediction And Control Of Jinsha Lakes In Hangzhou

In recent years, with the rapid development of city construction, and with the improvement of people’s living standard, in order to improve the city’s ecological environment and living environment, enhance the vitality and the image of city, artificial lakes development with the city construction. However, in the construction and operation process of artificial lakes, because of small water collection area, small water exchange, low water capacity, weak ecological capacity, water quality is prone to deterioration, instead of destruction of the living environment.In this paper, based on the development situation of artificial lake, with the jinsha lake as an example, through the analysis of pollution sources and the water quality target, the pollution sources and water quality standards for the jinsha lake is determined. And based on the water quality prediction model application, through the analysis of the water amount and the lake pollution load of the jinsha lake, the supplementary water of Jinsha lake is determined. In addition, according to the water quality standard of the lake, and the source of water, the jinsha lake chooses the reasonable selection of lake water and the lake water quality control measures.There are mainly two aspects of quality control measures with the lake:one is the water source of the Qiantang river was pretreated, and then transported to the lake; two is in the lake district set biological reaction processing facilities and the lake water purification facilities, and in the lake, the rational allocation of aquatic plant, animal and microorganism, can form a balanced ecosystem for water purification. Finally, an ecological and beautiful artificial lake will be formed by the rational design.
