改性粉煤灰处理含铬废水的实验研究

Experimental research of using properties-modified-FA to treatment chrome-containing wastewater

本文采用Na2CO3和粉煤灰按质量比1∶3进行混合,然后高温焙烧得到改性粉煤灰,通过正交实验优化了改性粉煤灰对废水中Cr6+的吸附性能,获得了较好的含铬废水的处理工艺,该处理方法简单、可靠,运行费用低。

Abstract：This text use sodium carbonate and fly ash mix ratio of 1：3 by mass, and then high temperature ： roasting to obtain the modified fly ash, through orthogonal experiment Cr^6＋ adsorption properties of wastewater, to obtain a betterchromium wastewater treatment process, the treatment method is simple, reliable, low running costs.
