Lake Water Environment Capacity Analysis Based on Steady-State Model

Estimating of the water environment capacity is an important content of the assessment of regional environmental impact. Water environment capacity is very important in the field of environmental science and it can provide reliable data environmental planning and management of water. In this paper, lake is the research object and one-dimensional model of water quality is built according to the conservation of mass of pollutants in the lake. Meanwhile, the method for confirming model parameters is put forward. The model is based on investigation in lake water environment and is applied to calculate water environment capacity of Xiaohu. Main pollutants of Xiaohu are COD, TN, fluoride, volatile phenol, BOD5, whose water environment capacity are 581.008kg/d, 185kg/d, 61.553kg/d, 0.387kg/d, 25.098kg/d accordingly.
