中文摘要
      研究了高铁酸盐对深圳2种原水水中藻类的去除效能.实验结果表明,在处理以小球藻为主的东湖水时,单纯PAC混凝就可有效地去除水中的藻类,藻类去除率均在95%左右.在处理含藻量多,以颤藻为主的铁岗原水时,单纯PAC混凝除藻效果不理想,投加少量高铁酸盐进行预氧化,再投加PAC混凝,可使水中藻的去除率提高10%~20%,去除率高达97.85%.而且用高铁预氧化除藻法明显优于传统预氯化方法.
英文摘要
      This paper studied the efficiency of algae removal by ferrate from two kinds of raw water which were collected from Donghu and Tiegang reservoir respectively. The experimental results showed that the removal efficiency of algae reached about 95% only through PAC coagulation when the raw water was extracted from Donghu reservoir in which most of algae was Chlorella. But dealing with Tiegang raw water in which the majority of algae were Oscillatoria, terrate was used as pre oxidant coupling with PAC coagulation not only using PAC to flocculate and the efficiency of algae removal could be up to 97 85%. However this treatment method using ferrate as pre oxidant overmatched the traditional method prechlorination for algae removal.
