摘要
为保护和改善环境,治理太湖水体富营养化,太湖流域某城镇污水处理厂进行了提标改造。采用旋流沉砂池/A2O生化池(投加聚氨酯悬浮生物填料)/二沉池/混凝沉淀池/V型滤池/紫外消毒池工艺,取得了良好的处理效果,出水水质达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。
In order to protect and improve the environment and control the eutrophication of Taihu Lake, the upgrading reconstruction project of a municipal wastewater treatment plant in the Taihu Lake basin was carried out. The combined process of rotational flow grit chamber, A2/O biochemical tank （adding polyurethane suspended bio-packing）, secondary sedimentation tank, coagulatory settler, V-fil- ter and UV disinfection tank was used, and a good result was achieved. The effluent indexes meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002）.
