摘要： 采用物化（铁碳微电解、催化氧化）预处理高浓度废水后，利用水解酸化-A/O工艺处理混合废水，处理量为80 m3/d。运行实践表明：处理出水COD低于500 mg/L，氨氮低于35 mg/L，出水水质达到接管要求，预处理工艺的COD去除率达64%，硝基苯去除率达94%，效果明显。

Abstract: After physicochemical(ferric-carbon micro-electrolysis and catalytic oxidation)process has been used for pre-treating highly concentrated wastewater,and hydrolytic acidification-A/O process used for treating mixed wastewater. The designed treatment capacity is 80 m3/d. The operation practice results show that the treated efflu-ent chemical oxygen demand(COD)is less than 500 mg/L,and ammonia nitrogen concentrations is less than 35 mg/L. The effluent water quality can meet the requirements for taking over standard. The COD removing rate of the pretreatment process reaches 64% and the removing rate of nitrobenzene reaches 94%,having remarkable effect.
