| 摘 要： | 通过试验研究探讨了上向流聚苯乙烯滤料直接过滤原水时硫酸铝和三氯化铁的过滤特点，试验结果表明：对浊度为20NTU的原水，在硫酸铝和三氯化铁的投加量均为5mg／L时，三氯化铁过滤时出水浊度较低，但它引起的水头损失增长较快。试验结果还表明：上向流聚苯乙烯滤料直接过滤时，阳离子型聚合物T3010的投加量对过滤周期、出水水质、水头损失都有着非常重要的影响。

| Abstract: | The characteristics of ferric chloride and aluminum sulfate used as coagulants in the up- flow direct filtration through polystyrene filter media were discussed. The experimental results showed: when ferric chloride and aluminum sulfate were utilized in the direct filtration of raw water with turbidity 20NTU, the effluent turbidities of former is a little lower, but its head loss increasing velocity is a little bigger. The experimental results also showed that the dosage of cationic polymer T3010 has important influ-ences on effluent quality,filtration period and head loss of the up- flow polystyrene direct filtration. |
