不同助滤剂对废水中重金属铜离子吸附性能研究

Evaluation on Filter Aids' Properties of Adsorbing Copper Ion in Waste Water

对稻壳灰、硅藻土和粉煤灰3种助滤剂对废水中重金属铜离子的吸附性能进行了对比研究。

Traditional filter aids like perlite, diatomite and cellulose fibers cost much in waste water treat- ment, and the rice husk ash can be applied to reduce application cost of filtering aids. The rice husk ash, di- atomite and coal ash＇ s properties of absorbing copper ion in waste water were compared and discussed.
