Study on the Water Environmental Capacity and the Sewage Control of the Sushui River

Abstract:

In order to know the environmental capacity, improve the continual deterioration of the water quality in Sushui River, and promote the harmonious development of economy and aquatic environment, we did the following research. Based on the 1-D steady-state water quality model, the outfalls are generalized, and then we derived the formula for calculating water environmental capacity of each reach. According to the information of water quality, hydrology data and the discharge distribution of the river, we chose COD, ammonia nitrogen and volatile phenol as the main control factors, and some formulas were used to calculate the water environmental capacity of COD, ammonia nitrogen and volatile phenol. From which we got that annual water environmental capacity of COD, ammonia nitrogen and volatile phenol on the studied reach respectively arrive at 1257.897~1420.928t, 17.873~26.025t and 1.750~2.871t under different design terms. It is serious pollution in the Sushui River, combined with the status quo emissions, we found that under different design terms, the annual quantity of pollutants reduction of COD, ammonia nitrogen and volatile phenol arrive at 30.36×106t, 3.257×106t and 0.1745×106t.
