摘　　要：用复相光催化剂WO3／ZnO对含酸性黑染料的废水处理进行了研究探讨了光催化剂作用机理，讨论了光催化剂的配比、试液的起始浓度、光催化剂的用量、试液的pH值、双氧水的用量、光照时间与酸性黑溶液脱色率的关系买验结果表明：催化剂配比m（WO3）：mfZilo）18：7、试液起始浓度为5mg／L、催化剂用量为O400g、pH65、双氧水的用量为44hnmol／L、光照150min，酸性黑溶液的脱色率可迭996％。The treatment of waste water contaiiliilg acid black ） by WOJZnO is studied. Reaction mectluilisnl of photocatalysis is probed. The relationships between the composition of heterogeneous photocatalyst, the starting concentration of AB, amount of photocatalyst, pH, amount of H2Q, illumiilation time aM the decolorizing rate of AB are discussed. The results show tbut the decolorizing rate of AB can reach 99.6% by using WO3/ZnO as heterogeneous photocatalyst, with the composition of heterogeneous photocatalyst 18：7, the initial concentration of AB 5rag/L, amount of catalyst-0.400g, pH 6.5, amount of H2O2=4.41 inmol/L,illumillution time-150min.
