摘要
从污水水质和水量分析、工艺选择及构筑物单体设计等方面,阐述了某县市的污水处理工程设计。该工程采用了改良型氧化沟工艺,经运行实践证明,该工艺具有较强的耐冲击负荷能力、脱氮除磷效果良好、出水水质稳定、投资省、运行维修费用低、节能等优点,出水水质可满足《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级标准的B标准。
The paper expounds the design of a municipal sewage treatment project from the aspects of sewage quality and quantity analysis, process selection, individual structure design, etc. The project has adopted the process of improved oxidation ditch. The operating practice has proved that the process has the advantages such as strong shock-load resistance, good nitrogen and phosphorus removal effects, stable effluent quality, small investment, low operating and maintenance cost and energy saving.
