肉类加工废水处理技术

Treatment of Waster from Meat Food Processing

某肉类加工企业进行废水处理,采用预曝气调节—气浮—生物接触氧化处理工艺,对设计规模为1500m3/d的实际工程运行结果表明,该处理工艺处理出水COD、BOD、SS分别为53mg/L,14.5mg/L,<50mg/L,氨氮4.6mg/L,pH7.41,超过设计指标和国家《污水综合排放标准》(GB8978-1996)一级标准要求。

The technique of presunheating adjustmentgas floatationbiological contact oxidation is applied in a meat food processing enterprise to the processing waste water thereafter. The real operation of an engineering project in the scale of 1500 m\+3/d resulted in delivery of water processed containing COD,BOD, SS being respectively 53mg/L,14.5mg/L<50mg/L,ammonia nitrogen,which exceeds designated target and GB8918-1996 topclass standard issued by our national\<Waste Water Discharged Standards\>.
