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100 mg/L、电流密度为20 mA/cm2、电解质投加量为0.10 mol/L,反应120 min后,异噁草酮去除率达到94%,此时TOC去除率为57.9%,能耗为25 kWh/m3,且废水的可生化性能显著提高。
In order to effectively treat the wastewater containing clomazone herbicide, Sb-doped Ti / SnO2 electrode was used as anode and stainless steel was used as cathode. Electrocatalytic oxidation technology was used to degrade clomazone wastewater. The effects of different influencing factors The effect of the removal rate of oxalicum and the degradation of clomazone were analyzed. The results showed that when the initial concentration of clomazone was 100 mg / L, the current density was 20 mA / cm2, the dosage of electrolyte was 0.10 mol / L, the removal rate of clomazone reached 94% after 120 min reaction, When the TOC removal rate of 57.9%, energy consumption of 25 kWh / m3, and wastewater biodegradability significantly improved.
