污水深度处理微絮凝-砂滤工程实例

针对苏州某污水处理厂二级出水TP和SS不能达到一级A标准的情况,采用微絮凝-砂滤深度处理工艺,经过一年多的运行分析,出水稳定达GB 18918—2002《城镇污水处理厂污染物排放标准》中一级A标准,TP、SS和COD去除率分别为53%、59%和31%,每吨水实际运行费用约0.15元。

ENGINEERING DESIGN OF MICRO-FLOCCULATION-SAND FILTRATION OF ADVANCED WASTEWATER TREATMENT

Aiming at the TP and SS of secondary effluent in a sewage treatment plant in Suzhou can not achieve the first-order standard A,micro-flocculation-sand filtration advanced treatment is applied.After the operation and analysis for more than a year,the effluent can consistently achieve the first-order standard A of "Pollutant Discharge Standerd of Urban Sewage Treatment Plant"(GB 18918—2002) and the removal rate of TP,SS and COD was 53%,59% and 31%,respectively.The operating costs 0.15 Yuan per ton of water.
