摘要

摘要: 以南京市十字河为例,采用潜没式生态床、生态浮床、生物接触氧化床3种技术组合为6种生态净化方案,通过在不同的单元输入不同的降解参数,用QUAL2K模型对6种不同的水处理技术组合方案进行模拟,通过对模拟效果的综合评价选取最佳方案。结果表明:上、中、下游依次设计为生物接触氧化床、生态浮床、潜没式生态床的处理效果最佳,其BOD、NH₃-N、TN和TP削减率分别为49.50%、32.81%、35.94%和45.27%。

Abstract: Taking the Shizi River in Nanjing City as an example, six kinds of ecological purification scheme were combined by submerged ecological bed, ecological floating bed and biological contact oxidation technology. By inputting different degradation parameters to different units, the six kinds of water treatment technology combination scheme were simulated using the QUAL2K model. The best scheme is selected through the comprehensive evaluation of the simulation effects. The results show that the optimal scenario is comprised of a bio-contact oxidation system in the upstream, followed by an ecological floating bed in the middle stream and a submerged ecological bed in the downstream. Under this scenario, the reduction rates for biochemical oxygen demand (BOD), ammonia nitrogen (NH₃-N), total nitrogen (TN) and total phosphorus (TP) were 49.50%, 32.81%, 35.94% and 45.27%, respectively.
