摘要
本文研究了几种常用的国产混凝剂处理制革废水的效果，得出聚合硫酸铁是一种比较经济有效的混凝剂，配合ＰＡＭ助凝剂可以取得更好的效果。。艺上采用混凝气浮，可全部去除硫化物，出水总铬≤１ｍｇ／Ｌ，ＣＯＤ去除率可达７０％—８０％。
Some common coagulants made in China for tannery wastewater treatment were studied.The result showed that the PFS is a most economical and effective one. When the PAM was added as a coagulant aid, the treatmeat efficiency can be increased remarkably. When coagulative floatation is used as the treatment process, the sulfide in the wastewater can be removed completely and the total chromium in the effluent can be less than 1 mg/L, the COD removal efficiency is 70 % - 80 %.
