高铁酸盐预氧化对颤藻去除效果及机理的研究
Study on the efficiency and mechanism of Oscillatoria removal from drinking water by ferrate
【摘要】 以深圳市铁岗水库水源水为主要研究对象 ,通过与单纯投加聚合氯化铝 (PAC)相比 ,研究了高铁酸盐预氧化对铁岗水中颤藻 (Oscillatoria)的去除效能 ,藻类去除率高达 97 85 % .证明在处理较难去除的颤藻时 ,高铁酸盐与PAC联用 ,可显著提高对藻类的去除效能 .初步研究了预氧化方法对水中颤藻去除的机理
【Abstract】 Compared with the effect of algae removal only by PolyAluminium Chloride (PAC) coagulation treatment, the effect of removal on Oscillatoria from raw water, which was extracted from Tiegang reservoir, by ferrate pre oxidation coupling with the PAC coagulation was studied. The result showed that the efficiency of Oscillatoria removal by ferrate pre oxidation was up to 97 85% and was higher than that of algae removal only by PAC. the mechanism of algae removal by ferrate pre oxidation was also be studied.
