摘要:
用球墨铸铁屑处理含铬废水的试验研究的结果表明：当含铬废水Cr6+含量为4.5mg/L时，其Cr6+去除率>90%，出水Cr6+含量≤0.42mg/L，小于国家标准的0.5mg/L；当温度为21℃、铁屑粒度为1.2～2.0mm时的最佳工艺方案为：进水pH值为2.0～2.4，出水沉淀时pH值为8.0～9.0，接触时间为15～21min。
Abstract:
The results of experimental study of treatment on chromium-bearing wastewater with nodular cast iron scrap show when chromiwm-bearing wastewater Cr6+ is 4.5 mg/L,the rate of eliminating the roots on Cr6+>90%,Cr6+ of water exit (0.42 mg/L)≤0.5 mg/L (standard of the state),when temperature is 21℃ and the size of iron scrap is 1.2~2.0 mm,optimum technological plan:pH of water inlet is 2.0~2.4,pH of water exit sediment is 8.0~9.0,time of contact is 15~21 min.
