Influence of Chlorination Conditions on Amount of Trihaloacetic Acids Formation

Experiment was made，in which Harbin reservoir water was taken as source water to observe the influence of chlorination conditions such as chlorine dosage，reaction time，pH value，organics concentration and varieties of disinfectant on the amount of trihaloacetic acids formation．Based on the experiment results，control measures were proposed for the formation of disinfection byproducts such as trihaloacetic acids through optimizat ion of disinfection．
