Abstract

In order to study the effect and influencing factors of bromate removal by ultraviolet treatment in drinking water, by carrying out laboratory test in simulated water and raw water samples, the action of UVC and UVA on bromate were investigated. The results indicated that bromate transformes into bromine ion under UVC treatment, but there was a small amount of UVA in the UVC lamp emission spectrum. Separate experiments on UVA treatment of bromate indicated that UVA could be considered as an interference factor for UVC treatment of bromate, and it should be restricted in the UVC lamp emission. The conversion of bromate to bromide was inhibited by suspended matter, which led to a rise of water turbidity and had influence on the reduction of bromate by UVC. When the water pH was 5.5~9 the same UV dose, the reduction of the bromate concentration by UVC treatment did not change significantly.
