摘要
混凝-沉淀试验表明在原水中投加混凝剂能提高出水NTU、SS、COD和TP的去除效果,出水NH3-N、NO3--N、TN的去除效果不理想。采用火山岩-活性炭组合滤池和紫外消毒工艺对广州市猎德污水处理厂二沉池出水进行处理,在滤速为12m3/h,紫外辐射剂量为400W的条件下,其出水水质可以达到景观用水标准。
NTU, SS, COD and TP were removed preferably by flocculation precipitation. Remove effect of NH3-N, NO3--N, TN were not good. Effluent water quality reached landscape water standard, when volcanic rock-active carbon combined filter and ultraviolet disinfect processes were put to used for advanced treatment of out water of Guangzhou Liede wastewater plant. The optimal condition were 12m3/h filter velocity and 400 w ultraviolet radiation.
