摘要：

用铁-氧电池,对含有高浓度有机物的头孢类抗生素生产废水进行预处理试验,研究了若干因素对其COD去除率和可生化性的影响。结果表明:对于含有高浓度有机物的头孢类抗生素生产废水,该法是十分有效的预处理手段,COD去除率可达73%,废水由难生化转变为易生化,BOD5/COD由0.22提高到了0.53。

Abstract:

The cephalosporin santibiotic wastewater, which containshighly concentrate dorganisms, istreatedbyusingiron- oxygen battery technology. Theopti mumcondition isstudied in detail. The resultsin this study showthat the methodis avery effective pretreatment technology, the CODremoval efficiencyis evenupto73%.Wastewater isturnedintoeasy biodegradability from difficult biodegradabilityafter pretreatedwiththis method,and BOD₅/CODhasbeenup to 0.53from0.22.
