Preparation research of micro-electrolysis material

以铁炭为原料,在传统铁炭微电解材料中添加金属化合物添加剂,通过两段烘焙工艺制得新型微电解材料。研究了新型铁炭微电解材料处理印染废水的条件及影响因素,主要研究了在不同的铁炭质量比、金属化合物添加剂、铁炭质量占微电解材料总质量百分比、温度以及焙烧时间等条件下制备的材料对印染废水的处理。研究表明,用铁炭质量比为1∶1,添加剂按氧化铝∶氧化钛∶氧化镁∶氧化锰∶氧化钙比例为5∶3∶2∶1∶1混合,铁炭质量占微电解材料总质量百分比为60%电解材料,在1 100℃下焙烧2 h制备的新型铁炭微电解材料处理印染废水效果最佳。对印染废水的COD_(Cr)、色度去除率达到76.8%,84.5%。

The research has made a new iron-carbon micro electrolytic material which consists of activated carbon powder,scrap iron,a variety of metallic oxides and two stages of roasting.The effect of micro-electrolyses ＇ ratio of ingredients is materials,the sintering time and temperature on the treatment-effectiveness of dyeing wastewater are investigated systematically,and the method of optimum preparation is determined.The result shows that it is the best reaction conditions：Fe：C was 1：1,Al2O3：Ti2O3：MgO：MnO2：CaO was 5：3：2：1：1,the percent of iron and carbon is 60%,the sintering time is 2 h and the sintering temperature is 1 100 ℃.The COD and shade removing rate are up to 76.8% and 84.5%.
