| 摘 要： | 采用石墨电极-低压脉冲电解方法,对含油废水去油影响因素进行了单因子实验研究。结果表明:该方法对浓度为95 mg/L的含油废水中油的去除率超过75%。油去除率随电解时间、电压增加而增大,达到一定值后受油分子扩散浓度影响而增加缓慢;适宜占空比、脉冲频率即可发挥脉冲作用,消除钝化效果,又可增强电解效果;体系pH值对电解影响较大,酸性和中性电解效果好于碱性条件;适当调整电极直径、电极间距可改善电解效果。 |
| 关 键 词： | 低压脉冲电解 含油废水 石墨电极 |

| Abstract: | The test of influencing factors on removal rate of oil was performed.The results showed that the removal rate for 95 mg/L oily wastewater exceeds 75%.The electrolytic effects increased with the electrolysis time prolonging and electrolysis-voltage increasing,the increase got slow at a certain value because of the concentration proliferation.The appropriate pulse frequency,duty cycle can not only eliminate effects of passive,but also enhance the effect of electrolysis.The pH values affected electrolysis grea... |
