摘要
富营养化导致的饮用水源中藻类的大量繁殖给饮用水厂运行和水质安全带来了负面影响。常规的混凝工艺去除藻细胞的效果并不理想,预氧化常被用来强化混凝除藻的效果。该文详细讨论了影响预氧化强化混凝去除藻类的影响因素,如氧化剂种类、藻细胞性质、天然有机物(NOM)、藻源有机物(AOM)和混凝剂种类等,通过对这些影响因素的探讨,为提高水体中藻类的去除率和优化混凝剂与预氧化的搭配提供了参考,并为预氧化强化混凝去除水体中藻类的应用提供一定的指导。
Harmful algae in water source caused by eutrophication brought serious effects to the drinking water plants and water quality security. The removal efficiency of algae by conventional coagulation was limited. Therefore, pre-oxidation was frequently used for enhancing the removal efficiency. The effects of different influencing factors including oxidant, coagulants, algal cell properties, natural organic matter and algogenic organic matter of removing algae by pre-oxidation enhanced coagulation were reviewed. This review could effectively provide reference for choosing the optimizing coagulant and oxidant.
