| 摘 要： | 为有效处理含异噁草酮除草剂废水，以Sb掺杂Ti／SnO2电极为阳极，不锈钢板为阴极，采用电催化氧化技术对异噁草酮废水进行降解，研究了不同影响因素对异噁草酮去除率的影响，并分析了异噁草酮的降解效果。结果表明，当异噁草酮初始浓度为100mg／L、电流密度为20mA／cm2、电解质投加量为0．10mol／L，反应120min后，异噁草酮去除率达到94％，此时TOC去除率为57．9％，能耗为25kWh／m2，且废水的可生化性能显著提高。

| Abstract: | In order to find an effective method for treatment of clomazone wastwater, the degradation was studied by electrocatalytic oxidation, and Sb doped Ti/SnO2 electrode was used as anode and stainless steel plate as cathode. The main influencing factors and degradation effectiveness of clomazone were discussed in the study. Results showed that when the initial concentration of clomazone was 100 mg/L, current density was 20 mA/cm2 and the electrolyte dosage was 0. 10 mol/L, 94% of clomazone was removed within 120 min. Meanwhile, TOC removal rate was 57.9% , energy consumption was 25 kWh/m3 and the biodegradability of the wastewater was improved obviously. |
