摘要
将自制的改性膨润土作为吸附混凝剂,处理不同的染色废水,COD去除率和脱色率分别可达90%和95%,且废水pH在4—9范围内时,脱色率较稳定.通过改性膨润土与膨润土废水处理效果的比较,初步表明改性膨润土可提高染色废水处理效率.
AbstractThe modified bentonite as a kind of adsorb-coagulation was used for treating dyeing wastewater. When the dies of modified bentonite are 2. 4g/L ,COD and colour removed rate reach 90% and 95% respectively ; moreover , decolour rate is hardly affected by pH. These results are better than those of the treating efficiency of bentonite. The experimental results show modified bentonite is a sort of adsorb-coagulation with greatly practical potential.
