摘要：

A detailed quantitative study of the effects of bromide and ammonia upon the trihalomethane balance obtained when water is chlorinated under varying conditions is described. Experiments at a chlorine dose of 2 and 8 mg L-1 utilizing waters having total organic carbon (TOC) contents of 2.5 and 12.7 mg L-1 demonstrated the significance of these parameters and bromide (0-2000 μg L-1) on the overall reaction process. Trihalomethane distribution is principally depepdent on the bromide concentration. An outline kinetic interpretation of the data is presented, and factors influencing the consumption of bromide and free chlorine are evaluated. The effect of ammonia (0.5 mg L-1, NH3-N) upon trihalomethane formation under breakpoint chlorination conditions was investigated.
