However, the surplus residual chlorine can affect people's taste and smell, destroy the quality of water. Moreover, in the process of disinfection, chlorine can react with organic matter and produce a series of hydrochloric ether such as chloroform, bromoform, bromodichloromethane, chlorodibromomethane and so on, these matters can cause to some extent cancer to human body.

但是，水中过量的余氯会影响水的口感和气味，破坏水的品质；此外，在消毒过程中，氯与水中残余的有机物产生化学作用，生成一系列氯代烃如三氯甲烷、溴仿、溴二氯甲烷、氯二溴甲烷等，这些物质会对人体产生一定程度的致癌作用；对于以自然水源作为生活用水来源的城市必然要对水加氯消毒后才可使用。

The mechanism of crystallization of flue gas desulfurization sludge waste into α form calcium sulfate hemihydrate through differential scanning calorimetry is obtained.

The effects of NaAA content on the mechanical properties and water-swellable properties were studied. The experimental results show that NaAA has good reinforcement for the EVM vulcanizate. EVM vulcanziate reinforced by NaAA has higher water absorbing rate and equilibrium water absorbing ratio. When the NaAA content is 50 phr, the maximum water-absorbing ratio of EVM vulcanziate is 278.3%. With the incorporation of ion into immersing media, the water-absorption ratio of EVM vulcanizates decreases. FT-IR analysis confirms that NaAA formed in the process of compounding and underwent polymerization during vulcanization.
