| 摘 要： | 通过纯水条件下的模拟研究,考察NH4＋和H2O2在单独和联用时对臭氧氧化过程中溴酸盐形成的抑制效能。结果表明,单独投加NH4＋能显著降低溴酸盐的生成量,并对水中臭氧浓度衰减无明显影响;投加H2O2大于0.20 mmol/L时,能在一定程度上抑制溴酸盐的形成,但加快了水中臭氧浓度的衰减;同时投加过量H2O2和NH4＋时,...

| Abstract: | Simulation studies in pure water were conducted to investigate the inhibition of ammonia addition,H2O2 addition and combined addition of ammonia and H2O2 on bromate formation during ozonation process.It was shown that ammonia addition decreased bromate formation obviously,and had no measurable influence on ozone degradation in water.The addition of H2O2 with more than 0.20 mmol/L could inhibit the formation of bromate,but accelerate ozone degradation in water.When excess of ammonia and H2O2 were added toget... |
