摘　　要：实验研究了电解法作为预处理,降解敌百虫农药废水的效果,详细探讨了电解时间、废水pH值、电解电压、电解电流及加入电解质的质量等因素对电解效果的影响。实验结果表明,在循环电解池中,废水的pH值=6～8时,保持电压在30V的条件下,废水中CODCr的降解率为40.00%。同样条件下,加入电解质[ρ(NaCl)=10g·L-1]100mL时,废水的降解率可达到42.80%。This experiment studies the electrolysis as a pretreatment of wastewater degradation of trichlorfon results discussed in detail electrolysis, pH wastewater electrolysis voltage, current electrolysis in the electrolyte and adding content on the effect of electrolysis. Experimental results showed that the electrolytic cell cycle, wastewater pH = 6 - 8, the 30 V voltage conditions, Wastewater degradation rate of 40.00%. Under the same conditions, adding electrolyte NaCl 10 g· L^-1 100 mL, Wastewater degradation rate can be achieved 42.80%.
