摘要
氯气消毒是传统的饮水安全方法 ,最近研究表明 ,消毒后的饮水中能形成致癌致岐变的氯仿。本文通过条件实验研究了加氯量、p H值、接触时间、反应温度对饮水中氯仿含量的影响 ,并通过正交实验 ,确定了影响氯仿形成的主要因素 -加氯量和 p H值。
Chlorine (Cl 2) as disinfectant used in drinking water is conventional safe method, but some related researches in recent years find chloroform in disinfected drinking water which can cause cancer and deformity. This paper was conducted through conditional experiments to demonstrate that chlorine dosage, pH, persistent time, reaction temperature are mian parameters in forming chloroform indrinking water, it also determined through orthogonal experiments two main parameters which influence chloroform concentration in drinking water-chlorine dosage and reaction temperature.
