该专利涉及一种利用粉煤灰和生物质制备催化剂的方法及其电化学氧化降解处理有机废水的方法。催化剂的制备方法如下:先将生物质破碎、筛分后,用去离子水清洗、烘干,将烘干的生物质加入到过渡金属离子溶液中浸渍吸附;同时将粉煤灰烘干后加入到过渡金属离子溶液中浸渍吸附;将吸附过渡金属离子后的粉煤灰和生物质过滤、洗涤、烘干;将二者按一定比例混合均匀,加入黏结剂、水玻璃和液体石蜡,挤压成型,烘干,高温煅烧活化,得到催化剂。该催化剂可用于电化学氧化降解
This patent relates to a method for preparing a catalyst using fly ash and biomass and a method for electrochemical degradation of organic wastewater. The preparation method of the catalyst is as follows: firstly, the biomass is crushed, sieved, cleaned with deionized water, dried, and the dried biomass is added to the transition metal ion solution for impregnation and adsorption; meanwhile, the fly ash is dried and added To the transition metal ion solution immersion adsorption; adsorption of transition metal ions fly ash and biomass after filtration, washing, drying; the two are mixed in a certain ratio, adding binder, water glass and liquid paraffin, extrusion Forming, drying, calcination and activation at high temperature to obtain a catalyst. The catalyst can be used for electrochemical oxidative degradation
