摘　　要：采用电-芬顿、芬顿-微电解、三维电催化、微电解工艺对预处理双甘膦废水的效果进行了比较研究。试验结果表明:对于高浓度有机磷双甘膦废水,采用上述四种工艺处理后的总磷去除率分别为66.2%、88.1%、87.8%、92.2%。铁碳微电解除磷效果最优,进一步对其影响因素进行试验,结果表明:pH为3,反应时间为2h,铁碳比为1:1时微电解法对双甘膦废水的总磷去除率可达92.2%,微电解联用对废水总磷去除率为96.8%。Electro-Fenton,Fenton micro-electrolysis process,Multi-dimensional electro-catalytic process and micro-electrolysis process have been used for the comparative study of PMIDA wastewater pre-treatment effects.The result showed that the total phosphorus（TP） removal rate for high PMIDA concentrations wastewater were 66.2%,88.1%,87.8% and 92.2% respectively by using four process mentioned above.The TP removal effect of micro-electrolysis process was best,so its results were further tested.The result showed that when pH value was 3,reaction time was 2h and iron and charcoal volume ratio was 1：1,the TP removal rate was 92.2% by using micro-electrolysis process.The TP removal rate of was 92.2% by using two micro-electrolysis processes.
