上向流聚苯乙烯滤料直接过滤原水──Ⅱ凝聚剂投加量的影响

Testing Direct Filtration of Raw Water Using Upflow Polystyrene Filter──Ⅱ The Influences of Coagulant Dosages

通过大量的实验研究，探讨了上向流聚苯乙烯波科直接过滤原水时，凝聚剂投加量对过滤效果的影响．试验结果表明，采用该工艺直接过滤时，凝聚剂投加量是一个最关键的因素，它对运行效果起着决定性作用．

Based on numerous tests and extensive research, the influences of coagulants dosages on the effect of the direct filtration of water using and upflow polystyrene filter were discussed. The test results showed the dosages of coagulants were the key factors for the direct filtration of water using this filter and played a decisive role in its performance.
