氯化及预氯化反应条件与卤代烃生成研究

Study on Chloration and Prechloration Conditions and the Formation of Alohydrocarbon

以巢湖源水为源水,进行了加氯量、不同工艺段加氯、反应时间、源水中有机物含量、pH等氯化反应条件对卤代烃生成量影响的实验,并在此基础上,对巢湖源水和董铺源水进行了生产试验,提出了给水处理控制预氯量、优化常规处理、进行深度处理、降低三卤甲烷等消毒副产物生成量的控制对策。

Effects of chloration conditions as chlorine-adding amount, time of reaction, pH value as well as chlorine-adding at different stages on the yield of halohydrocarbon were tested on the sourqe water of Chaohu Lake. The optimized conditions were adopted in the tap water production of the source water from the Chaohu Lake and Dongpu Reservior. Some countermeasures such as prechloration amount control, routine treatment optimization, intensive treatment, lowering amount of sterilization outgrowth like trihalomethane were proposed.
