摘要
采用常规烧杯搅拌试验方法对聚铁硅型复合混凝剂的混凝性能进行了系统的研究 .结果表明 ,所研究聚合铁硅型复合混凝剂的混凝性能随氧化硅的种类与Si/Fe比的不同而有显明的差异 ,而碱化度的影响较为有限 .三类氧化硅中Silica(A)与Silica(B)的特性比较类似 ,显著地降低了混凝剂的电中和能力 ,仅仅在较高投药量时带来混凝效果一定的改善 .Silica(C)的引入对电中和能力的影响不大 ,但显著地提高了混凝效能 。
The coagulation behavior of new IPF PFSi was investigated in detail by the traditional jar test.The experimental results show that the coagulation behavior of PFSi is in significant difference according to the kinds of silica introduced and the Si/Fe ratio.Silica(A) and silica(B) exhibit a similar effect,both decrease the charge-neutralization ability of the compostite IPF,while the turbidity removal is only improved under high dosage.However,the silica(C) has little effect on the charge-neutralization abi...
