| 摘 要： | 通过静态实验研究对苯二酚废水(300mg·L-1)在复极性三维电解槽中的电化学氧化过程,考察了填料质量比例、电解电压、支持电解质浓度以及初始pH值对对苯二酚和CODCr去除效果的影响。结果表明:随施加电压的增加,对苯二酚和CODCr去除率先升高后降低再升高;在弱碱(pH=8.5)条件下,对苯二酚CODCr去除率最高;电解质浓度和填料质量对对苯二酚降解影响较大。当电解质Na2SO4浓度为0.03mol·L-1,电压值为6V,初始pH值为8.5,填料质量比例为1:2时,对苯二酚和CODCr去除率分别达到83.96%和39.9%。

| Abstract: | In the paper,the p-benzenediol wastewater treatment process by bipolar electrocatalysis oxidation in the three-dimensional cell is studied.The influence of the ratio of packing quality,the supporting electrolyte concentration,electrolysis voltage,and the initial pH value on the removal of hydroquinone and CODCr are investigated by static experiment.This study clearly indicated the removal of hydroquinone and CODCr with electrolysis voltage value increased at first,then decreased and increased again at last;... |
