摘　　要：以毛皮脱脂废液作为研究对象,经高压脉冲电絮凝法处理,去除废水中的有机物和悬浮物,从而达到循环利用的要求。考察了极板间距、通电时间、极板电压、脉冲频率、初始废液p H和温度对毛皮脱脂废液的处理效果的影响。实验结果表明,当脱脂原液p H值为6.83,处理水量为2.4 L时,高压脉冲电絮凝电源脉冲电压30 V,脉冲频率4 000 Hz,通电时间30 min,极板间距1.5 cm,废液温度35℃为其最佳处理条件,废液COD、氨氮、色度、浊度去除率分别可达到80.74%、70.69%、89.29%、99.71%。In this research, study on the removal of organic pollutants and suspended solid with pulsed electrocoagulation treatment in the degreasing water for recycling. The functions of relevant influencing factors are discussed, including electrode distance, reaction time, pulse voltage, pulse frequency, pH and temperature. The experimental results show that the removal rates of COD, NHa-N, colority and turbidity reach 80.74%,70.69%,89.29%,99.71%,when the degreasing water pH is 6.83,the amount of treated water is 2.4 L, eleetrode distance is 1.5 cm, reaction time is 30 rain, pulse voltage is 30 V,pulse frequency is 4 000 Hz and temperature is 35 ℃.
