先前的研究已经确定了臭氧氧化系统中天然有机物（NOM）、混凝剂和颗粒相互作用的许多机制。本研究考察了臭氧氧化对阳离子聚合物和聚合物-金属盐混合物混凝的影响。预分区降低了与聚合物反应的NOM的浓度，减少了有机碳的去除、聚合物混凝剂的需求，以及直接过滤过程中水头损失的累积速度。在使用双混凝剂（明矾聚合物或三氯化铁聚合物）的系统中，臭氧氧化的效果是单独观察到的混凝剂效果的混合。包括20个参考文献、表格和图表。

Prior investigations have identified many of the mechanisms by which natural organic matter (NOM), coagulant, and particles interact in ozonated systems. This study investigated the effects of ozonation on coagulation with cationic polymer and with polymer-metal salt mixtures. Preozonation decreased the concentration of NOM that reacts with polymer, reducing organic carbon removal, polymer coagulant demand, and the rate of head loss buildup during direct filtration. The effects of ozonation in systems using dual coagulants (alum-polymer or ferric chloride-polymer) were a blend of the effects observed for the coagulants individually.
