促進酸化法における臭化物イオンのフミン質分解に及ぼす影響と臭素酸イオン生成の制御 The Effect of Bromide Ion on Decomposition of Humic Substances and Control of Bromate Ion Formation on Advanced Oxidation Process
The effect of bromide ion in raw water of water supply on oxidative decomposition of humic substances by advanced oxidation process (AOP) was investigated. The following properties became evident after studying the experimental results.(1) Bromide ion hindered oxidative decomposition of humic substances on ozonation alone and ozonation with UV-irradiation, because of product of hypobromous acid.(2) On ozonation with H2O2 dosage, bromide ion did not hinder the decomposition of humic substances and product of bromate was formed little.(3) On ozonation with UV-irradiation, all of bromide ion decomposed was oxidized to bromate.(4) In case of containing bromide ion in raw water, the ozonation with H2O2 dosage was better available treatment than the other AOP.
