混凝法处理木薯淀粉废水

The Coagulating Process of Treating the Waste Water in Producing tapioca

用混凝法处理木薯淀粉废水，研究了混凝剂的种类、投加量、沉降ＰＨ值及沉淀时间对木薯淀粉 废水ＣＯＤｃｒ去除率的影响．在选定的实验条件下，用聚合硫酸铁（ＰＦＳ）作混凝剂，木薯淀粉废 水ＣＯＤｃｒ去除率达８８％以上．

The waste water in producing tapioca is treated by the coagulating process. The cleaning efficiency of the CODcr in the waste water is studied by changing the experiment conditions such as the kinds of coagulating agents, the quantity of coagulating agent, the pH of the waste water, the settling time, under elected experiment conditions, polymerized ferrous sulfate(PFS) as coagulating agent, the cleaning efficiency of the CODcr in the waste water is above 88%.
