摘要
本研究采用静电处理技术以改善活性污泥絮体的物理特性，以提高活性污泥的沉降性和脱水性．结果表明静电场对污泥颗粒的ξ电位有明显的降低作用；随着静电场电流的增加，污泥颗粒的ξ电位降低，电流１００ｍＡ为稳定转化点．当电流为１００ｍＡ时，生物絮体的物理特性最佳．这些结果对活性污泥法处理系统的改善有重要意义．
This study aims at improving the efficiency on activated sludge sedimentating and dewatering by means of low-voltage electrostatic treatment.Experiments results show that the effects of the electrostatic treatment is very remarkable in respect of lowering the Zeta potential of activated sludge particles.While the electric current is increasing, the Zeta potential is declining. The steady transformation current point is 100mA, and at this point biological flocs have the most optimum physical characteristics for sedimentation. These results are significant for the improvement of activated sludge wastewater treatment.
