摘要
以攀钢燃煤炉产生的粉煤灰为改性对象,经过不同的预处理过程对粉煤灰进行改性,然后对垃圾渗滤液进行降解实验.研究结果表明,燃煤炉产生的粉煤灰在经过酸洗和550℃条件下热处理后,其吸附性能和催化性能都将得到显著的改善,在pH为4.0,H2O2投加量为50 mg/L,反应1 h预处理后的粉煤灰对苯酚的去除率达到76%,能够较好的对含酚废水进行预处理.
After various modified processes,the fly ash generated from coal stove of Panzhihua Iron and Steel Group can degrade the phenol-containing wastewater.Experimental results show that after acid washing and being heated under the conditions of 350 ℃,the adsorption and catalytic properties of fly ash from coal stove the will increase.After being pretreated with pH 4.0,50 mg/L concentration-added H2O2,reaction of 1 h,the fly ash can remove 76% phenol-containing wastewater,can better degrade of the landfill leachate.
