| 摘 要： | 针对脉冲电浮水处理装置的特点,分析了影响该技术处理效果的因素,根据絮凝过程运动学的理论,以钢球模型的简化方式建立自由粒子浮选去除模型,仿真得到自由粒子浓度随时间变化过程.该数学模型为设计絮凝池尺寸参数,以及选择电浮处理参数提供理论依据.结果表明:当处理时间为20～25 min时,可以使自由粒子去除率达到90%以上,这与实验数据相当吻合.

| Abstract: | After an analysis of the characteristics of impulse electro-flotation wastewater treatment equipment,we discussed the factors affecting the efficiency of this technology.A simplified steel ball model was used in the construction of the free particle flotation removal model based on the kinematical theory of flocculation processes.Variation of the concentration of a free particle over time was stimulated.This mathematical model showed a significant role in the design of the flocculator parameter,and provided theoretical guidance on the choice of electric flotation parameters and the design of the electric flotation treatment equipment.The simulated results suggest that when the treatment time was between 20 and 25 minutes,the free particle removal rate could exceed 90%,a finding consistent with the experimental data. |
