摘要: Abstract Bromo-DBPs (disinfection by-products) are generated by bromide and disinfectant in drinking water disinfection, which have adverse effects on human health. In this study, of coexisting anions removal aluminium coagulation were investigated. It was observed that removed 62.1–87.0% raw water, while the efficiency achieved 82.8–99.2% deionized through combination Br − with Al(III) various pathways. The significantly affected bromide. Removal decreased 11.5, 21.2, 14.6, 8.0 40.8% addition HCO 3 , SO 4 2− Cl NO H 2 PO respectively, for their affinities or accelerating formation Al(OH) 3(am) . These results demonstrated bromo-DBPs could be controlled though removing enhanced coagulation.
