摘要
本文研究了用电絮凝法处理受污染源水过程中，电流密度、ｐＨ、停留时间对水中ＣＯＤ、细菌和浊度的去除效果的影响，发现电絮凝法对ＣＯＤ、细菌和浊度的去除效果显著；增大电流密度可以加快ＣＯＤ和细菌的去除速度，但使单位能耗增大；ｐＨ小于７和大于８有利于ＣＯＤ的去除。
The influence of current density, pH and treatment time on the removal of COD, bacteria and turbidity in polluted natural water was studied when the water was treated in an electrocoagulation process. It was found that the process can reduce the concentrations of COD and bacteria as well as turbidity significantly. The increase of current density can accelerate the removal of COD and bacteria but it increases the power consumption perunit volume water. It is helpful for the removal of COD that the pH of treated water is less than 7 and over 8.
