皮革厂行业中含铬废水处理工艺分析

Analysis on the treatment process of Chromiumcontaining Wastewater in Tannery Industry

现如今,加强皮革含铬废水的回收利用尤为重要,皮革含铭废水主要由铬鞣、复鞣等工序产生。铭是具有毒性的,而在这些工艺中,铬的使用率很低,因此就需要采取多种方法将皮革含铬废水进行回收与利用,本文主要分析了皮革厂含铬废水来源及特点并介绍了皮革含铬废水处理方法。

nowadays,it is particularly important to strengthen the recovery and utilization of leather chromium-containing wastewater,which is mainly produced by chrome tanning,retanning and other processes.Ming is toxic,and in these processes,the utilization rate of chromium is very low,so it is necessary to take a variety of methods to recover and utilize leather chromium-containing wastewater.this paper mainly analyzes the sources and characteristics of chromium-containing wastewater from tannery and introduces the treatment methods of leather chromium-containing wastewater.
