| 摘 要： | 在臭氧氧化处理微污染原水的工艺中，臭氧对有机物的去除效果与水中还原性无机物的含量有关。通过试验考察了水中NO2^--N对臭氧氧化有机物的影响。结果表明，水中较高浓度的NO2^--N可消耗臭氧投加量的40％左右，并降低了臭氧对THMs前体物的去除率，也影响其提高水中可生物降解有机物浓度的能力；碱度的增加可增强NO2^--N对臭氧的竞争利用，降低臭氧对TOC和UV254的去除率。 |

| Abstract: | In the ozone oxidation process for micro-polluted raw water treatment, the effects of organic matter oxidation by ozone are related to the reductive inorganic concentration in water. The influence of NO2^--N on organic matter oxidation by ozone was studied. The results show that high concentration NO2^-- N in water can consume ozone dosage by 40% and reduce the removal rate of THMs precursor and the enhanced degree of biological degradation ability of water after ozonation. The increasing of alkalinity can increase the quantity of ozone consumed by NO2^-- N and decrease the TOC and UV254 removal rates. |
