摘要
讨论了一种生态型印染废水混凝剂对以分散、还原、活性、酸性类染料为主的印染废水脱色处理效果,并与印染厂常用的无机高分子混凝剂和有机脱色剂进行了对比试验.结果表明:该混凝剂在中性和酸性条件下具有较好的混凝脱色效果;混凝剂本身的生化降解性好、安全无毒、不会对环境产生二次污染,可用来替代或部分替代无机高分子铝盐类混凝剂.
The decolorization effect of the ecological coagulant used in dyeing waste water was discussed, and compared it with common inorganic polymeric coagulant and organic decolorant used in dyeing company. The experimental result shows that coagulant has remarkable decolorization effect under neutral and acid conditions. In addition, it has good biodegradabijity, safety and innoxious and there is no secondary pollution on environment. So it may be used for substitution or part substitution of inorganic polymeric aluminium salt coagulant.
