含有机污染物废水电解及机理研究

A study on the electrolysis process and mechanism of wastewater with phenylethylene

利用电解氧化技术对有机污染物废水进行了研究。首先,研究了电解机理,电解作用有4种:絮凝作用、浮选作用、直接氧化还原作用、间接氧化还原作用;然后,研究了影响处理效果的因素,这些因素主要包括:电流密度(电流强度或电压)、pH值、电解时间、电解质投加量、极板间距等。试验结果表明,在其它条件不变时,最佳电流强度为4A,最佳pH值为7,电解时间为80min,电解质投加量越高COD去除率越高,最佳极板间距为2cm。

Studies on electric oxidation process for tetraphene latex and phenylethylene waste water are performed to treat the effluent （ phenylethylene is the main pollution） of coagulating treatment system. Phenylethylene is difficult to disintegrate. Electrolysis has four effects： coagulating effect, floatation effect, direct oxidation and reduction effect and indirect oxidation and reduction effect. The influencing factors on treatment effects include： current density （current intensity or eurrent voltage）, pH, lasting electrolysis time, quantity of electrolyte and distanee between plate electrodes. It is revealed that the best current intensity is 4A ; the best pH is 7 ; the best lasting time of electrolysis is 80min, the best distance between plates is 2cm and the more electrolyte is added, the result is better.
