A pilot-scale experiment for treating acrylic wastewater was performed by using anaerobic-aerobic biomem-brane process. The total volume of device was 58m3,filled with soft fibre paddings,refract-flow was used inanaerobic part and plug-flow in aerobic part respectively,its volume ratio was 1 : 3.Experimental result showed well,and the effluent would meet with the current criteria for drainge and alsocould be discharged into Hongzhow Gulf directly. Owing to the trace content of TSS in effluent only 20-30mg/L,it established the basis for removing of settling tank.When retention time was 21. 86h,backflow ratio was 3. 15,the removals could reach 93. 49% for COD,99. 57% for BOD5,and 69. 10% for TN,respectively. The effluent then would contain CODcr,44. 74mg/L,BOD51.98mg/L,NO3-N 6. 80mg/L,NaSCN 0. 45mg/L,acetone 0. 05mg/L,and the chemical sbstancessuch as isopropanal,acrylonitrile etc. are undetectable.

上海石油化工总厂为大型石油化工、化纤联合企业,各分厂所排放的大量废水,先自行处理,然后送往总厂汇同生活污水再一起处理,1987年每年所处理的总污水量近10万m~3。污水通过二级生化处理后进一步去除了COD、BOD,最终出水符合了国家排放标准。但建厂时,氨氮达不到上海市现行排放标准(氨氮<15mg/L)。特别是由于污水量大,折算为氨氮总负荷量相当可观,所以,如何除氨氮是一项十分重要的研究课题。 氨氮的污染源,主要来自于腈纶厂、化工二厂和生活区的废水。针对实际情况,结合化工废水毒性大,易受冲击等特点,我们于1984年初开始采用缺氧—好氧生物膜法系统,对水质净化厂的石化混合污水和腈纶厂废水进行了一系列小试,取得了较满意的效果。在此基础上,于1986年7月对腈纶废水进一步开展中试研究,并已取得了成果。

Air oxidation treatment for SO_3~(2-) in inorganic waste water is discussed, according to experiments accomplished by the author during his study in Japan. Several expressions are provided for reference. This method is characterized by its large capacity of treating a great amount of waste water within a relatively short time. It is easy for operation and worthy for popularization.
