生活污水处理工艺中的除磷设计

Phosphorus Removal Design in Domestic Sewage Treatment Process

指出了随着人们生活水平的提高,所排生活污水中总磷含量也有所提高,采用生物除磷为主的工艺很难满足稳定达标排放的需求。分析了生活污水中磷的形态、浓度和除磷工艺的去除效能,根据不同的进水浓度和处理程度要求,提出了稳定达标的工艺流程及设计建议。

With the improvement of people’s living standards,the total phosphorus content in the discharged domestic sewage has also been increased.It is difficult to meet the demand for stable discharge standards by using biological phosphorus-based processes.This paper analyzes the form and concentration of phosphorus in domestic sewage and the removal efficiency of phosphorus removal process.According to the different influent concentration and treatment level requirements,the engineering design proposal for stable compliance is proposed.
