摘要
我国主要采用前体物试验(FP试验)对饮用水中消毒副产物(DBP)的形成进行评估,但这种方法无法对配水系统中DBP产量进行评估。为此借鉴美国的评估方法,根据中国的具体情况,建立了评估配水管网中消毒副产物产量的新方法———UFC试验(uniformformationconditions),确立了UFC试验的条件:温度为(20±1.0)℃,pH值为7.5±0.2,培养时间为(24±1)h,24h后游离余氯为(1.0±0.4)mg/L,并建立了UFC的分析检测方法。
In China, the formation potential (FP) test was mainly used to assess the disinfection byproduct (DBP) in drinking water, but the test failed to assess the DBP production in water distribution system. Therefore, by using the American assessment method for reference and according to the practical condition in China, a new method-uniform formation conditions (UFC) test was established to assess DBP in water distribution system, and the conditions of UFC test were determined as follows: temperature (20±1.0) ℃, pH 7.5±0.2, culture period (24±1) h, and free chlorine residual (1.0±0.4) mg/L after 24 h. Besides, the analysis method was set up for UFC.
