【摘要】 水中COD过高对人类健康和水环境会产生不利影响,我国将COD作为重点控制的水污染物指标,COD超标的原水在使用前以及废水在排放水体前都必须进行处理。选取硫酸铁、硫酸铝和聚丙烯酰胺等3种典型絮凝剂进行去除水中COD的实验,对絮凝剂用量等影响因素进行了探讨,得到了最佳工艺参数。实验结果表明,聚丙烯酰胺具有优良的去除COD性能,在水处理领域将有广阔的应用前景。
【英文摘要】 COD is one of the key indexes of water pollutant in China,and high concentration of COD in water will do harm to people's health and water environment.Therefore,any source water and water containing high COD should be treated before use or drainage.Experiments of COD-removing performance were done with typical flocculants such as ferric sulfate,aluminum sulfate and polyacrylamide.Effecting factors such as flocculant dose were also observed,and the optimal parameters were obtained thereafter.Experiments show...
