摘　　要：探讨了生物接触氧化法处理制革工业废水的工艺,研究了各种工艺条件诸如停留时间、进水负荷,气水比、温度和pH 值对废水处理效果的影响,并求得了最佳工艺条件。试验表明,本法能有效地处理制革工业废水,在适宜条件下,COD_(Cr)、BOD_5和色度的去除率分别可达79—86%,90—94%和80—90%,COD_(Cr)和BOD_5的容积负荷分别为2.237 kg/(m^3·d)和1.357 kg/(m^3·d)。The sewage discharged from leather industry was treated by biologicalcontact oxidation.The effects of retention time,loading in influent water,ratio of air to water,temperature and pH on treatment efficiency weredetermined,hence an optimal technology was obtained.The results showthat the sewage can successfully be treated by this process with the rom-oval of COD_(C_t),BOD_5 and colority being about 79～86%,90～94% and 80～90%,respectively.The volumetric loadings of COD_(Cr) and BOD_5 were cal-culated,they were 2.237kg/m^3·d and 1.357 kg/m^3·d,respectively.
