摘要
研究Fe2+-H2O2氧化絮凝耦合除去藻类污染。结果表明Fe2+-H2O2在原水pH值为7.8的条件下,对藻细胞和有机物的去除率可达到90%以上。Fe2+-H2O2对藻类污染的去除主要是利用.OH自由基的氧化作用和中间Fe3+络合物的絮凝作用的有效耦合实现的。对藻细胞的去除主要受絮凝作用控制,对其代谢有机物的去除主要受.OH自由基氧化作用控制。
The effect of coupling of advanced oxidation and flocculation with Fe^2＋-H2O2 reagent on algae-pollution removal was studied.The results showed that,when the raw water pH was 7.8,the removal rate of algae cells and organisms by Fe^2＋-H2O2 could be above 90%.The removal of algae-pollution by Fe^2＋-H2O2 was obtained mainly based on the efficient coupling of the effects of·OH free radical oxidation and flocculation of middle Fe^3＋ complexes.The removal of algae cells was mainly controlled by flucculation effect,while the removal of organic pollutant of the metabolism was mainly controlled by oxidation of ·OH free radical.
