摘　　要：本文研究了废铬鞣液在浸酸、铬鞣和复鞣循环系统中的变化。结果表明,废铬液循环法工艺稳定,铬的排放率和循环利用率分别为0.5％和27％,废铬鞣液可形成封闭式循环。The changes of used chrome tan liquor in pickling -tanning and retanning recycling system had been study. The present work indicated that the technology of direct liquor chrome recycling is stable ,that the rate of discharge and recycling utilization ration of chromium is 0. 5% and 27% respectively,and that used chrome tan liquor can form a close cycle.
