摘要
在水处理中,吸附法是一种重要的物理化学方法。研制价格低廉、选择性好、易再生的水处理吸附剂是环保产业发展的急切需要。文章综述了粉煤灰、膨润土、离子交换树脂等几种价廉易得的吸附材料在印染废水脱色处理中的应用,并指出今后的发展方向。
In water treatment, absorption is an important physical and chemical method. The preparation of low-cost, good selective, easy-renewable water absorbent is in urgent need of environmental protection industry. The article summarizes the application of several low-cost, easily available absorbents such as the fly ash, bentonite, ion exchange resins, in printing and dyeing wastewater decolorizing treatment, and put forwards some ideas for future improvement direction.
