Research on Optimizing Control Technology of Supplementing Water of Water System in Yangzhou City——Taking Erdao River as an Example
In order to ensure landscape and control black-odors of the water body in the city and control algae breeding,selected DO as the control index,supplementing water yield was calculated according to exogenous pollutions and sediment pollution release endogenous pollutions such as the overflow sewage and rainwater.First comparatively typical inland(Erdao River) in Yangzhou were investigated.Dobbins-Camp BOD-DO water quality model was used and BOD was instead by COD to calculate supplementing water yield for class V of river water quality(DO≥ 2 mg/L,CODMn≤15 mg/L).The results show that Dobbins-Camp water quality model can provide scientific decision making tool to regulation project of inland waterway in yangzhou city.
