The study of venous channel water pollution load reduction technologies

In this paper, Hongqi River of WuJin River watershed (china) was selected as an example, aims to use QUAL2K water quality model simulation water environmental capacity of the Hongqi River, forecasting the pollution load of the Hongqi River basin, and compared to the actual emissions of pollution load, calculated the load reduction rate for satisfying the water quality objectives. At the same time, using QUAL2K simulation different water quality improvement programs contains submerged-type eco-bed technology, bio-contact oxidation technology and ecological floating bed technology, selected optimal program, and calculate the load reduction rate of the river end when implement this optimal program. According to comparison of the load reduction rate for water quality meet the standards and the load reduction rate of the optimal program, proposed effective measures to reduce pollution load of Hongqi River basin. The result shows that environmental management strategies or integrated engineering measures need to be taken to reduce the TN by 23.20% can make the water quality meet the standards. In order to meet the environmental capacity of Hongqi river, effectively improve water environmental quality, presented through source pollution control, non-point source pollution intercept and environmental management measures to reduce the amount of pollutants flow into the river, and with the implementation of load reduction key technologies in the river, together make the Hongqi River water quality meet the standards.
