摘要：

采用物化（电催化氧化、铁炭微电解）预处理高、中浓度混合废水后，利用厌氧+两级A/O工艺处理综合废水，处理量为300 m³/d。运行实践表明：物化预处理对COD 的去除率为32%，整个工艺处理后出水COD 低于500 mg/L，氨氮低于35 mg/L，盐分低于0.6%，出水水质达到接管要求，工艺处理效果明显。

Abstract:

After the physicochemical pretreatment process(electrochemical oxidation,ferric-carbon micro-electrolysis)was used for the pretreatment of the wastewater with mixed high and medium concentrations,the anaerobic+two-stage A/O process has been used for the treatment of comprehensive wastewater. The designed treatment capacity is 300 m³/d. The operation results show that by physicochemical pretreatment the removing rate of COD could reach 32%,and the whole process treated effluent COD is lower than 500 mg/L,ammonia-nitrogen lower than 35 mg/L,and salinity lower than 0.6%. The water quality of the effluent can meet the take-over requirements. The effect of technological treatment is obvious.
