摘　　要：文中通过进水pH值、脉冲电压、脉冲频率、占空比及水力停留时间的条件试验,找出了各因素对高压脉冲电凝法去除各种污染物的影响规律。研究结果表明:利用高压脉冲电凝法处理电镀废水时,设计进水pH值3~5,脉冲电压200V,脉冲频率600 Hz,占空比0.5,水力停留时间20 min,可以得到较好的处理效果。In this paper, based on the condition tests of pH of infiuent, pulse voltage, pulse frequency, duty ratio and hydrau- lic retention time, the influence laws of various factors on pollutants removal by high - voltage pulse electrocoagulation were found out. The results showed that, under the condition of pH = 3 - 5, pulse voltage = 200 V, pulse frequency = 600 Hz, duty ratio = 0. 5 and hydraulic retention time = 20 rain, the treatment of electroplating wastewater by using high - voltage pulse electrocoagulation could get better effect.
