壳聚糖-活性污泥复合吸附剂处理含锌废水

Treatment of Wastewater Containing Zinc by Chitosan-activated Sludge Composite Adsorbent

实验制备了壳聚糖-活性污泥复合吸附剂并用于处理含锌废水,考察采用壳聚糖包埋活性污泥制备复合吸附剂的最佳配比、发泡剂量、交联剂质量浓度等因素对复合吸附剂制备效果的影响。实验表明,不同质量比、Na OH固化液质量浓度、发泡剂量、交联剂质量浓度制备出的壳聚糖-活性污泥复合吸附剂的吸附能力均不同。

In this experiment,chitosan-activated sludge composite adsorbent was used to treat wastewater containing zinc,investigating the effects of the optimum ratio,foaming dose and crosslinking mass concentration of the composite adsorbent prepared by chitosan embedded activated sludge on preparation effect of composite adsorbent.The results showed that the adsorption capacity of chitosan-activated sludge complex adsorbent was different with different mass ratios,NaOH curing liquid mass concentration,foaming dose and crosslinking agent mass concentration.
