摘要
研究了饮用水消毒过程中卤代烃形成的各种条件及控制技术。结果表明：加氯量多时卤代烃形成多、水温高时卤代烃生成快、加凝聚剂后因pH值下降能控制卤代烃形成、加氨氮后生成氯胺可进一步降低饮用水中的卤代烃。
Various conditions and control techniques of the formation of halogenated hydrocarbons in the disinfection tha more halogenatedhydrocarbons are formed when more chlorine is added. The formation of halogenated hydrocarbons is accelerated at higher water ternperature,and can be controlled by adding coagulant due to decrease of pH value. while further reduction of halogenated hydrocarbons can be achieved byadding ammonia nitrogen with the formation of choramine.
