摘要
介绍了利用工业废弃物煤渣处理酸性废水和酸性重金属离子混合废水的方法,测定了各工艺参数对处理效果的影响。实验表明:利用煤渣处理酸性废水,反应速度快,60g煤渣能使pH=1.90的100ml酸性质水在3min内pH值升高到6.00以上;重金属离子去除率在97.3％以上;其经济效益和社会效益十分明显。
The process of treating acidic wastewater with or without heavy metal ions by coal cinder is introduced. The experiment showed that the process had the merits of favourable reaction velocities. 60 grams of coal cinder could make increase in pH value from 1.90 to 6.00 of 100 ml acidic wastewater in 3 minutes. And the removability of heavy metal ions was better than 97.3 %.
