摘要
采用化学还原+重金属捕集+气浮过滤组合工艺处理重金属废水。结果表明:处理后的出水水质中重金属等各项指标均达到《污水综合排放标准》(GB8978—2002)所规定的一级水质排放标准,COD去除率达到40%以上,同时此工艺在工程实践中取得了最佳工艺参数,可为类似工程提供参考。
An integration process of chemical reduction,heavy metal chelating and air floatation was adopted to treat wastewater containing heavy metals.The results showed that after treatment,the indicators of the effluent concerning heavy metals all complied with the discharge level I regulated in the Integrated Wastewater Discharge Standard （GB8978-2002）,and the removal rate of COD was over 40％.Furthermore,best process parameters were obtained during such engineering application,providing reference to other similar engineering projects.
