摘　　要：以山羊服装革加工过程为例,分析了制革加工过程中污染物的产生和各工段水中污染物的分布规律。结果表明:浸灰和复灰废水是化学需氧量(COD)的主要来源,分别占总量的34.13%和18.5%;氨氮主要来源于脱灰工段,占整个工段水氨氮总量的50.24%;整个工段水中氨氮总量占总氮的48%。The sources and distribution of pollutants in each process of leather processing was discussed, using the goat clothing leather proessing as the example. The results show that the liming and reliming waste water are the two biggest contributors of Chemical Oxygen Demand （ COD）, which account for 34.13% and 18.5% respectively. The ammonia nitrogen is mainly generated from deliming process,which accounts for 50.24%. The total ammonia nitrogen is about 48% of total nitrogen in all the process waste water.
