铝碳微电解法降解水中邻苯二甲酸酯

采用铝碳微电解法降解水中邻苯二甲酸酯（PAEs）。首先考察了初始废水pH、铝碳质量比和反应时间对邻苯二甲酸二甲酯（DMP）降解率的影响，然后分别考察了超声波频率、其他金属的添加和H₂O₂加入量对铝碳微电解法降解模拟混合PAEs废水中DMP、邻苯二甲酸二乙酯（DEP）和邻苯二甲酸二丁酯（DBP）的影响。实验结果表明：在初始DMP质量浓度为20 mg/L、初始废水pH为12.0、铝碳质量比为1∶1、反应时间为30 min的条件下，DMP降解率达49.94%;在上述最佳反应条件下处理DMP，DEP，DBP的质量浓度分别为20，10，8 mg/L的模拟混合PAEs废水，当超声波频率为80 kHz时，模拟混合PAEs废水中DMP，DEP，DBP的降解率分别为63.38%，32.75%，32.23%，当铝铁质量比为100∶1时，DMP，DEP，DBP的降解率分别为59.61%，37.39%，31.50%;添加铜和H₂O₂对PAEs的降解有抑制作用。

Degradation of Phthalate Esters in Water by Al-C Microelectrolysis

Phthalate esters（PAEs） in water were degraded by Al-C microelectrolysis process. The factors affecting the degradation of dimethyl phthalate（DMP）,diethyl phthalate（DEP） and dibutyl phthalate（DBP） were studied. The experimental results show that：Under the conditions of initial DMP mass concentration 20 mg/L,initial wastewater pH 12.0,Al-C mass ratio 1∶1 and reaction time 30 min,the DMP degradation rate is 49.94%;The simulated PAEs wastewater with 20,10,8 mg/L of DMP,DEP and DBP mass concentration is treated under the optimum conditions,the degradation rates of DMP,DEP and DBP are 63.38%,32.75%,32.23% respectively when the ultrasonic frequency is 80 kHz,and 59.61%,37.39%,31.50% respectively when the Al-C mass ratio is 100∶1;The added Cu and H₂O₂ can inhibit the degradation of PAEs.
