The reduction of trihalomethane formation potential was discussed, which indicated that ozonation has a good removal for chlorofom and bromodichloromethane formation potential, but for dibromochloromethane formation potential the removal efficiency was undesirable and there was almost no removal for bromoform forming potential, Furthermore, when there was enough bromide in water, ozonation would have a promotion effect for bromoform formation potential.

通过研究臭氧对三卤甲烷生成潜能的去除规律发现，臭氧对三氯甲烷和二氯一溴甲烷生成潜能都有很好的去除，对一氯二溴甲烷生成潜能的去除效果较差，对溴仿生成潜能基本没有去除。当水中溴化物含量较高时臭氧对溴仿的生成反而具有促进作用。

In this paper, initiator is dissolved in 1-bromopropane which is solvent. Then the propene and hydrogen bromide that can be dissolved in 1-bromopropane are inlet in l-bromopropane when initiator is decomposing. The reaction occurs in fluid phase and high-purity 1-bromopropane is synthesized by one step method. In this paper, the material HBr is synthesized with NaBr and sulfuric acid at the presence of hydrobromic acid.

During the reaction,the bromide component has been converted to catalytically inactive benzylic bromide.In pure acetic acid medium,the "catalyst failure" occurs owing to the formation of benzylic bromide while in acetic acid-water medium,the solvolysis of benzylic bromide by water maintains the catalytic activity to some extent.

反应过程中溴组分会转变为无活性的苄溴，在纯醋酸溶剂中，催化剂会因苄溴的形成而发生催化剂失活现象；在醋酸-水混合溶剂中，由于水对苄溴的溶剂化作用会使苄溴还原为溴离子，一定程度上保持了催化剂活性；并且在一定范围内，含水量的提高有益于生成醛选择性的提高，研究表明，将混合溶剂的初始含水量控制在5-10wt。

HP3 identified as Zoogloea sp. is an effectively strain. Under the optimal degradation condition and ABAS concentration of 200～1200mg/L, the ABAS degradation followed negative exponential model. With the ABAS concentration increasing, the ABAS degradation was greatly regressed. Temperature was the most important factor influencing ABAS degradation. The functions of specific growth rate and temperature, degradation rate of ABAS and temperature were constructed respectively.
