摘　　要：采用电絮凝耦合类电芬顿处理总磷初始浓度约为100 mg/L的模拟草甘膦废水,结果表明:静态试验时,在极板间距2 cm∶2cm、电流密度7.5 mA/cm、初始pH值7、曝气搅拌的条件下,反应50 min后总磷去除率可达96.38%;动态试验中,基于优化条件反应70 min后运行2个周期,水力停留时间为36 min时,总磷去除率可达79.67%。The simulated glyphosate wastewater with an initial total phosphorus(TP)concentration of about 100 mg/L was treated by electro flocculation coupling electro-Fenton-like method.The results showed that in the static test,under the conditions of electrode plate spacing of 2 cm∶2 cm,current density of 7.5 mA/cm,initial pH 7 and aeration stirring,the removal rate of TP could reach 96.38%after 50 minutes.In the dynamic test,based on the optimized conditions,the TP removal rate could reach 79.67%when the HRT 36 minutes and running for 2 cycles after 70 minutes.
