Abstract

The invention relates to a method for removing bromate in water through oxidation reduction and a system thereof. The method comprises the following steps: firstly, controlling the dissolved oxygen concentration in the water at a lower level through the nitrification of ammonia salt and microbes on the active carbon; secondly, removing the bromate in the water through the reducibility of ferrous sulfate; and finally, removing excessive ferric ions in the water through a filtering unit. The system comprises a pretreatment working section for controlling the dissolved oxygen in the water, an oxidation reduction working section for removing the bromate and a filtering treatment working section for removing the excessive ferric ions, wherein the pretreatment working section is connected with the oxidation reduction working section, and the oxidation reduction working section is connected with the filtering treatment working section. The method can effectively remove the bromate in the water with a bromate removal rate of above 60 percent. The system has convenient operation and low running cost, can also be integrated with other technologies, and have very high practicability.
