摘要
某城镇综合污水处理厂出水COD、总氮、总磷等指标已不能满足太湖流域污水排放新标准的要求。通过强化预处理、改造生化系统、增加深度处理等一系列工程改造措施,使污水处理厂运行稳定,脱氮除磷效果显著,出水水质能稳定达到《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级A标准和《太湖流域城镇污水处理厂主要水污染物排放限值》(DB 32/1072—2007)中相关要求。
The effluent COD, total nitrogen, total phosphorus and other indicators of a municipal comprehensive wastewater treatment plant （WWTP） could not meet the new discharge standard in Taihu Lake Basin. Thus, a series of measures, such as enhancing the pretreatment, reconstructing the bio- ehemieal system and adding an advanced treatment system, were taken. After those, the WWTP operates stably, and the removal efficiency of nitrogen and phosphorus is obvious. The effluent can meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002） and the requirements of Discharge Limit Values of Water Pollutants for Municipal Sewage Treatment Plants and Key Industries in Taihu Lake Area （ DB 32/1072 - 2007 ）.
