废铬 鞣 液循环利用技术的研究&Ⅰ.废铬鞣液在循环系统中的平衡及提高其回收利用率的探讨

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 .

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 main reason that results in the differences is the high concentration sulfate ion in the used chrome tan liquor .

循环 铬 液中高浓度硫酸根离子的存在是造成上述差异的主要原因。

The changes of used chrome tan liquor in pickling-tanning and retanning recycling system had been study .
