摘要
针对铜冶炼厂污酸污水含高砷高硬度,采用“石灰+纯碱+酸性铁”法能有效的去除重金属的同时降低总硬,处理时无需加酸进行回调pH值,满足进入深度处理的水质要求。
The waste acid and waste water of copper smelting plant bearing with high arsenic and high hardness,the“lime+sodium carbonate+acid iron”method is adopted for effectively removal of the heavy metal and decreasing the total hardness,and there's no need to add acid for pH value adjustment,therefore the advanced treatment requirement of water quality can be met.
