摘要
某污水处理厂采用三沟交替式氧化沟工艺,为了使出水水质能够达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,采用高密度沉淀池/转盘滤池工艺进行提标改造,通过对比分析改造前后的运行效果发现,经深度处理后,出水BOD5≤5 mg/L、COD≤40mg/L、SS≤8 mg/L、NH3-N≤1 mg/L、TN≤12 mg/L、TP≤0.4 mg/L,出水水质全部达到甚至优于GB 18918—2002的一级A标准。
The Densadeg and rotary filter were used to upgrade and reconstruct a WWTP using triple oxidation ditch technology to allow the effluent quality to meet the first class A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18915 - 2002 ）. After comparison and analysis of the operation results before and after upgrading and reconstruction, it was found that after advanced treatment, the effluent concentrations of BOD5 , COD, SS, NH3 - N, TN and TP were equal to or less than 5 rag/L, 40 mg/L, 8 mg/L, 1 mg/L, 12 mg/L and 0.4 mg/L respectively, meeting and even surpassing the first class A criteria.
