摘要
采用兼性塘与好氧塘组合工艺对苯并三氮唑(BTA)废水进行处理.经过1年多的试运行,在废水进水CODCr氨氮,苯氨类的质量浓度分别为312.2～478.3,59.8～87.3,4.6～8.2 mg/L的情况下,对CODCr,氨氮和苯氨类等的去除率在69%以上,出水水质达到污水排放二级标准.
A process combining facultative pond with aerobic pond was used for the treatment of the wastewater from the production of benzotriazol(BTA). After more than one year of trial operation, the removal rates of CODCr, NH3-N, phenylamino group, etc., were all over 69% when the mass concentrations of CODCr, NH3-N, phenylamino group, etc. in the influent wastewater were 312.2 ~ 478.3, 59.8 ~ 87.3 and 4.6 ~ 8.2 mg/L respectively, and the quality of the effluent water met the specification for grade II in the wastewater discharge standard.
