利用粉煤灰改进含铜酸性废水硫化法处理工艺

Using fly ash to ameliorate vulcanized method treating acid wastewater containing copper

用粉煤灰对硫化沉淀法处理含铜酸性废水工艺进行改进试验 ,试验表明粉煤灰有吸附和絮凝沉降的作用 。

The test shows that fly ash has action of water treatment and coacervation subsidence. It can remar\| kably ameliorate defect of slow subsidence and difficult dewatering of vulcanized method.
