生物接触氧化工艺改造购物中心综合污水处理的应用

APPLICATION OF BIOLOGICAL CONTACT OXIDATION PROCESS IN REFORMING SHOPPING CENTER COMPREHENSIVE WASTEWATER TREATMENT

利用生物接触氧化工艺和调整鼓风量改造原处理工艺,处理购物中心综合污水,设计能力400m3/d。废水进水水质CODCr为1083～1146mg/L、SS为315～436mg/L;调试稳定后,出水水质CODCr为126～145mg/L、SS为65～83mg/L,CODCr、SS去除率分别为87%～93%、79%～81%,出水水质达到国家二级排放标准。

Biological contact oxidation process and regulation of aircapacity were used to modify the former process so as to dispose shopping center comprehensive wastewater.Whose design capacity was 400 m^3/d .COD_ Cr contained in influent was 1 083 ～ 1 146 mg/L ,SS 315～436 mg/L,after debugging, COD_ Cr in effluent was 126～145 mg/L,SS 65～83 mg/L,the removal rates of COD_ Cr and SS were 87%～93% and 79%～81%.The effluent quality could reach the standard of the national second class discharge.
