The Water Pollution Control Planning Research in Lingyuan Stream Segment of Daling River

Abstract

Through to analysis the influence of the effluent from the sewage treatment plant to the river water quality of Fangshen-Habaqi stream segment in lower reaches comprehensively, in order to achieve water pollution control and water function zone protection. This paper use QUAL2K model to simulate the influence to lower reaches water quality, and the simulation factor is BOD. The result showed that the downstream BOD concentration cannot reach the water quality standards Ⅲ. This paper provides some corresponding control measures, so as to provide the scientific basis of the water pollution control planning research.
