摘　　要：对于高氨氮的受污染水源水的预处理国内大部分水厂通常采用预氯化工艺.以某市受污染水源水为研究对象,通过烧杯试验探讨了氯胺的预氧化助凝效能。结果表明,同无预氯胺化相比,氯胺在低投加量(2.0 mg/L)时,可明显降低水样的滤后浊度和沉后浊度,并且氯胺的助凝效能随氯、氮比率的增加而增强.Considering that contaminated raw water mostly contain high Ammonia - N and a majority of water treatment plants use prechlorination process in China, efficiency of chloramine as a coagulant aid in enhancing coagulation was investigated by Jar stirring, using raw water sample of A city which was containing high concentration of NOM and bromide in winter. The results showed that, compared with no preoxidation, preformed chloramine apparently decreased the turbidity of settled and filtered water with low dosage （2.0 mg/L）, and the aid-coagulation efficiency was further enhanced with the increase of chlorine （Cl2） to Ammonia-N （N） ratio.
