摘要
河北省某县污水处理厂采用Orbal氧化沟+絮凝沉淀+纤维转盘滤池工艺处理生活污水,运行结果表明,该工艺对COD、BOD5、氨氮、SS、总氮等各项指标的去除率都在90%以上,出水水质优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,经过投加PAC辅助除磷后,出水中总磷也可达到一级A排放标准,该工艺效果稳定,成本低,在县城及小规模污水处理领域具有较好的适用性。
Aiming at the domestic sewage quality of a county in Hebei Province, the effect of Orbal oxidation ditch and advanced treatment on the sewage treatment was investigated by real-time monitoring the influent and effluent quality. The results showed that the removal rates of COD, BOD5 , ammonia nitrogen, SS, total nitrogen and other indicators were over 90% after treatment by Orbal oxidation ditch/ flocculation settling/fiber rotary filter process. Their effluent quality was better than the first level criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）. The concentration of total phosphorus in the effluent could meet the first level criteria after adding polyaluminum chloride. Due to its stable treatment effect and low cost, the combined process is suitable for county and small-scale sewage treatment.
