【摘要】 通过模拟由土壤进入水源中的有机物质在自来水净化系统消毒条件下所发生的卤化反应，探讨了测定土壤三卤甲烷生成潜能（ＴＨＭＦＰ）的方法，并对各种实验条件（如水土体积质量比、振荡时间、加氯量等）的设定进行讨论，确定了各实验条件分别为：过 ６０目筛土样，振荡 ４ ｈ，水样 ｐＨ为 ７.０± ０.１，反应温度２０℃，投加的氯的质量浓度为８ｍｇ／Ｌ，反应时间２４ｈ．更多还原

【Abstract】 A method for determining the trihalomethane formation potential (TUMFP) in soil is shown based on a simulating examination of halogenating reaction of THM precurors in raw waters from soils under the similar condi-tions as in water purification processes. The design of experimental conditions (such as water/soil ratio, shaking time, chlorine dose etc.) is discussed. The selected test conditions are as follows: soils passed through a 0.25 mm sieve, shaking time of 4 h, pH controlled at 7.0 ± 0. 1, chlorine dose of 8 mg/L, reaction temperature of 20 t, reaction time of 24 h.更多还原
