Study On Water Quality Assessment And Water Quality Simulation Of Daming Lake In Jinan

Lake is one of the important freshwater resources, which providing water to producing and living. However, with the development of economy and society and the increasing discharge of industrial waste water and domestic sewage, a large number of human activities have done harm to the lake environments. At present, the main environment problem of lakes is the eutrophication, especially urban lakes. Daming Lake in Jinan has been also plagued by water quality deterioration, including the pollution of the water total nitrogen, the total phosphorus, the transparency and the coliform and the eutrophication. In order to study the effective methods and measures to prevent, suppress and purify the lake water pollution and achieve the sustainable use and the virtuous circle of water resources, this paper study the water quality simulation of the lake on the present status and under the conditions of taking all possible measures, make analysis evaluation of the results, and provide the important basis to the water quality planning and the environmental quality management.This paper evaluated the water quality of Daming Lake from 2001 to 200S using artificial neural network model. On this basis, make water quality simulation by SMS software, which can intuitively show the distribution of pollutant concentration and the water flow of Darning Lake. Then make the water quality simulation of Daming Lake using scenario analysis. Through the comparison of results, the advantages of each plan can be intuitively shown so as to carry out the simple, excellent and scientific program for the Daming Lake water environment planning.
