摘　　要：制革及毛皮加工废水属于高浓度难降解有机工业废水,具有排水量大、水质水量不均、污染物高及成分复杂等特点,给废水处理带来极大的难度。以河南省新乡市某皮革企业废水处理工程为例,根据制革及毛皮加工废水的特点,将含铬废水、含硫废水、脱脂废水进行分质预处理再与其他废水混合进行综合处理,出水水质能够满足相关排放标准的要求。Tannery wastewater belongs to high-concentration refractory organic industrial wastewater,which has the characteristics of large water volume,uneven water quality and quantity,high pollutants and complex composition, which brings great difficulty to wastewater treatment. Taking a wastewater treatment project of a tannery enterprise in Xinxiang City,Henan Province as an example,according to the characteristics of tannery wastewater,the chromium-containing wastewater,sulfur-containing wastewater,and degreasing wastewater were pretreated and mixed with other wastewater for comprehensive treatment. The water quality could meet the requirements of relevant emission standards.
