摘要
用BDD(掺硼金刚石)作电极,采用循环电解法处理石油污水,研究了电解时间、槽电压及电极间距对有COD(化学需氧量)降解率的影响,实验发现在槽电压8 V、电极间距2 mm,经过5h电解废水的COD降解率达到了93.9%,并且做了阴极替换实验,最后对COD的降解机理做了分析.
The treatment of petroleum wastewater using bulk electrolysis was investigated by synthetic boron - doped diamond （BDD） thin film electrodes to explore the influences of the time, tank voltage and the distance of electrodes on the rate of the degradation . The rate of the gradation is up to 93.9% after 5 hour＇s electrolysis when the voltage is 8 V and the distance of the electrodes is 2 mm in the experiment. We also carried out an experiment of instead of cathode. The mechanism of the degradation of the COD was analyzed at last.
