摘　　要：化工产业是天津滨海新区重要的支柱产业,该行业废水是滨海污染物控制的主要威胁。针对常规单一方法存在的问题,试验选取滨海某化工区实际废水从内电解-Fenton、内电解-混凝、内电解-超声及微波强化氧化-光催化4种耦合去毒预处理工艺进行了研究。试验表明,与传统方法相比,内电解-Fenton法中H2O2的加入增加了污染物的降解途径,提高了对污染物的去除效率;内电解-混凝法对于制药废水的生物毒性有比较好的去除作用,不加PAM或Ca(OH)2的效果更佳;内电解-超声法对制药废水的生物毒性去除率可达92%,其可生化性提高45%;微波强化氧化-光催化法对大多数难降解物质有效,而对酚类物质降解效果不佳。Chemical industry is an important pillar industry in Tianjin Binhai New Area,wastewater from that industry is main threat to pollution control in that area,as it has non-biodegradable and other characteristics.To solve the problem in single conventional method,actual wastewater from a chemical industry park in Binhai New Area was selected,4 coupling pretreatment processes for detoxication,namely Internal Electrolysis-Fenton（IEF）,Internal Electrolysis-Coagulation（IEC）,Internal Electrolysis-Ultrasonic（IEU） and Microwave-enhanced Oxidation-Photocatalysis（MOP） process,were studied.Through those experiments,effect was verified and characteristic was known,the foundation was laid for the follow-up demonstration project application.It was shown that,comparing with conventional method,IEF process promoted removal rate of pollutants and saved dosage of chemical agent as H2O2 was added,its biotoxicity removal was 80%.IEC process has good removal to biotoxicity of pharmaceutical wastewater,although all B/C were improved,the result without PAM or Ca（OH）2 was best.IEU process has 92% removal rate to biotoxicity of pharmaceutical wastewater,and its biodegradability was increased 45%.MOP process was effective Abstract：Chemical industry is an important pillar industry in Tianjin Binhai New Area,wastewater from that industry is main threat to pollution control in that area,as it has non-biodegradable and other characteristics.To solve the problem in single conventional method,actual wastewater from a chemical industry park in Binhai New Area was selected,4 coupling pretreatment processes for detoxication,namely Internal Electrolysis-Fenton（IEF）,Internal Electrolysis-Coagulation（IEC）,Internal Electrolysis-Ultrasonic（IEU） and Microwave-enhanced Oxidation-Photocatalysis（MOP） process,were studied.Through those experiments,effect was verified and characteristic was known,the foundation was laid for the follow-up demonstration project application.It was shown that,comparing with conventional method
