改性聚合硫酸铁的制备及其在印染废水处理中的试验

Preparation of modified polymerized ferric sulphate and its decoloration and degradation of some textile dyes waste water

制备了乙酸改性聚合硫酸铁,并用此作絮凝脱色剂对印染废水的处理效果进行了实验,结果表明,改性聚合硫酸铁对印染废水表现出较好的脱色性能,最佳脱色率和CODC r去除率分别达到95.0%和75.7%。对脱色的最佳工艺条件进行了优化,在同等条件下,改性聚合硫酸铁的絮凝脱色性能优于普通聚合硫酸铁。

Modified polymerized ferric sulphate was prepared. The performance of modified polymerized ferric sulphate applied in textile dyes wastewater was studied. The results showed that it has better effects in removal of CODCr and decoloration than general polymerized ferric sulphate and its decoloration rate reached 95.0% and CODCr was 75.7%.
