摘　　要：石化废水在处理过程中,由于进水含盐量高,可生化性差,导致污水处理系统出水水质稳定性差。污水处理厂在不改变原有生化系统工艺流程和设施的前提下,通过投加生物增效药剂,增强了生化系统活性污泥的性状,出水COD稳定在25 mg/L,COD去除率提高11%左右,为石化废水处理厂的稳定运行提供了有力保障。Petrochemical wastewater has high salt content,poor biodegradability,resulting in poor stability of sewage treatment system.The properties of activated sludge are enhanced by the bio-enhancing technology without changing the original biochemical system process and facilities.The effluent COD of the biochemical unit was stable at 25 mg/L,and the COD of effluent was reduced by 11%,which provides a strong guarantee for the stable operation of the treatment of petrochemical sewage.
