摘要
采用石灰-纯碱软化/混凝的新方法对广西南丹刁江河水进行预处理,考察了澄清石灰水、纯碱、聚合氯化铝(PAC)和聚丙烯酰胺(PAM)的复合处理效果,确定了药剂的最佳投加量,提出了工艺流程设计新方案。试验结果表明,此方案对刁江河水硬度的预处理能达到工业用水要求,可以解决矿区枯水期选矿用水不足的问题。
To resolve the problem regarding hard river water in Diaojiang River, arising from pollution of mining industry and seriously hampering the downstream river water use, the author conducted lab experiments to investigate hard water softening and worked out a process based on the experimental result.
