微污染水脱氮除磷工艺浅析

因水体富营养化问题及城市供水水源污染问题,人们越来越关注微污染水的治理研究问题,传统的污水处理工艺已无法满足微污染水的处理要求。"曝气生物滤池-生物脱氮滤池-双层除磷滤池"工艺,是一种投资小处理率高的生物处理技术,能很好地解决微污染水脱氮除磷问题,使处理后的出水达到地表水环境质量Ⅲ类水体标准。

The Micro Pollution Water Denitrogenation and Dephosphorus Crafe Analysis

Because of water body eutrophication question and urban water supply water source contamination concern,the people pay attention to the micro pollution water more and more government research question,the traditional sewage treatment craft have been unable to satisfy the micro pollution water the processing request.This article introduces ＂activeness to filter the material biofilter-biology denitrogenation filter tank-double-decked except the phosphorus filter tank＂ the craft,is one kind invests the small processing ratio high biological treatment technology,can solve the micro pollution water denitrogenation and dephoshorization question,after causing processing the water leakage achieves the surface water environment qualityⅢKind of water body standard.
