摘　　要：以铜绿微囊藻源有机物为研究目标,研究了藻源有机物(AOM)不同组分消毒副产物生成势特性,探讨了Br^(-)、DOC等因素对其的影响,为水厂工艺控制提供理论依据。结果表明铜绿微囊藻AOM以小分子量和亲水性组分为主,相对分子质量<1 kDa和疏水性组分的三卤甲烷前体物(TCMFP)、二氯乙酸前体物(DCAAFP)和二氯乙腈前体物(DCANFP)生成量最高。随着Br^(-)浓度和DOC浓度的增加,溴代消毒副产物(Br^(-)DBPs)增加明显,DBPs生成总量呈现出上升趋势。The formation potential of disinfection by-products of different components of AOM were studied with Microcystis Aeruginosa as the research target,and the effects of Br^(-)and DOC were discussed,which provided theoretical basis for the process control of water.The results showed that AOM of Microcystis Aeruginosa was mainly composed of small molecular weight and hydrophilic components,and TCMFP,DCAAFP and DCANFP of molecular weight<1 kDa and hydrophobic components were the highest.With the increase of the concentration of Br^(-)and DOC,bromide by-products(Br^(-)DBPs)increased significantly,and the total amount of DBPs produced showed an upward trend.
