摘　　要：采用氢氧化钠改性的硅藻土处理含锌废水。改性硅藻土处理含锌废水实验结果表明,其最佳工艺条件为:吸附时间为40 min,吸附温度为40℃,废水的pH为7.5,改性硅藻土加入量为1.2g。在此条件下可使50 mL模拟含锌废水中锌的浓度由50 mg/L降到2 mg/L,锌去除率达96.0%。Zinc-containing wastewater was treated by using diatomite modified with sodium hydroxide. The experiment results of treatment of zinc-containing wastewater with modified diatomite indicated that the optimum conditions were as follows： adsorption time 40 min, adsorption temperature 40 ℃, pH 7.5, modified diatomite dosage 1.2 g. Under these conditions, concentration of zinc in 50 mL simulated zinc-containing wastewater was reduced from 50 mg/L to 2 mg/L, removal rate of zinc reached 96.0%.
