摘要
对用粉煤灰处理含锌废水进行了试验研究。探讨了粉煤灰用量、废水酸度、接触时间、温度等因素对除锌效果的影响。结果表明 :在废水 pH 4~ 1 1、Zn2 + 质量浓度≤ 1 50mg/L范围内 ,按锌与粉煤灰质量比为 1∶40 0投加粉煤灰进行处理 ,锌去除率大于 97% 。
The treatment of zinc containing wastewater with fly ash was experimentally investigated.The results showed that the rate of zinc removal was>97%,when pH=4~11?and zinc mass concentration ≤150?mg/L.The treating effluent meets the National Wastewater Discharge Standard.
