主要介绍了目前应用较为广泛的几种制革废水处理工艺及国内制革综合废水处理技术的发展现状,并对徐州皮革工业集聚区采用优化后的物化+生化+奥贝尔氧化沟工艺处理区域污水的实例进行重点了介绍,讨论了该工艺的优点以及系统运行时控制的各项参数,并分析污水处理状况和处理效果.%Tannery wastewater is characterized by complex components,high concentration of organic pollutants,much suspended solids,and serious pollution. Based on the composition and characteristics of tannery wastewater,several techniques with wide application on the treatment of tannery wastewater were introduced,as well as the current situation in China. This article gives an engineering example for treating the regional sewage from a leather industry cluster district in Xuzhou by the optimized techniques with biochemical,physicoehemical,and Orbal oxidation ditch processes. The advantages and each operation parameters were discussed,and the treatment condition and processing effect were analyzed.
