摘要
采取絮凝→芽孢杆菌生物降解(缺氧水解)→再絮凝→Fenton试剂氧化的流程对COD_(Cr)50000mg/L以上超高浓度抗生素废水进行了预处理实验研究。其中各阶段的COD_(Cr)去除率为30.31%、27.01%、32.88%、33.82%。通过预处理可使废水COD_(Cr)从50000mg/L以上下降到10000mg/L左右,有利于下一步的常规生化处理。本试验为超高浓度抗生素废水的预处理提供了实验数据。
The pretreatment of the antibiotic wastewater was studied.The process is:flocculation→a biochemical hydrolyzation by the acclimated bacillus(anoxic hydrolyzation)→re-flocculation→catalytic oxidation by Fenton reagent.Each chemical oxygen demand(COD_(Cr) ) removal efficiency of the processes is 30.31%,27.0%,32.88% and 33.82%.The chemical oxygen demand(COD_(Cr) ) of the wastewater was reduced from over 50 000 mg/L to about 10 000 mg/L.It provided a method of the pretreatment of antibiotic wastewater.
