摘要
研究了聚苯乙烯轻质(漂浮)滤料直接过滤特性.原水浊度、投药量、反应时间、滤速、滤床厚度、过滤方向等因素对过滤运行有不向程度的影响。分析了直接过滤机理,并用絮体的附着和剥离观点解释了各因素对直接过滤的作用.
The performance of the direct filtration of lightweight(or floating)polystyrcnc filter media is studied,in which the filtration effect is affected by various factors,such as the turbidity of raw water,the dosage of coagulant,the detention time of flocculation,the rate of filtration,the depth of filter bed and the direction of flow,etc.Based on the experimental results the mechanism of filtration is discussed preliminary,and the influences of all factors on the filtration are qualitatively analysed with attachmentdetachment theory.
