Abstract:

The effects of several advanced treatment methods for acrylic and its ester wastewater,which was biochemically treated,has been investigated.The removing rates of COD by Fenton process and microwave-assisted Fenton process can reach above 85%.The removing rates of COD by ozone oxidation process and iron carbon micro-electrolysis process are both lower than 40%,by ammonium persulfate-assisted ozone oxidation process can reach 79%,and by photoelectro-catalytic oxidation process is less than 8%.The iron carbon micro-electrolysis,Fenton,microwave-assisted Fenton and ozone oxidation can make the biodegradability of wastewater increase from 0.35 to 0.56,0.43,0.44 and 0.40,respectively.The photoelectro-catalytic oxidation process can make the biodegradability of wastewater decline sharply to 0.03.

Key words: acrylic wastewater, ozone oxidation, photoelectro-catalytic oxidation, micro-electrolysis, Fenton

摘要：

探索了几种方法对生化后的丙烯酸及其酯废水深度处理的能力。Fenton法和微波辅助Fenton法对COD的去除率>85%,臭氧氧化法和铁炭微电解法对COD的去除率均<40%,过硫酸铵辅助臭氧氧化法对COD的去除率可达79%,光电催化氧化法对COD的去除率<8%。铁炭微电解法、Fenton法、微波辅助Fenton法、臭氧氧化法可使废水可生化性由0.35分别提高到0.56、0.43、0.44、0.40,光电催化氧化法使废水可生化性锐减为0.03。
