摘　　要：以黄河水为研究对象,考察臭氧氧化降解和活性炭吸附去除水中有机污染物的效能。结果表明,在臭氧投加量为1～3 mg.L-1时,CODMn的去除率由8%升高到20%,之后其变化不明显;UV254的去除率由9%升高到30%,此时臭氧即可以将不饱和有机物大量去除。臭氧投加量为1～2 mg.L-1时,短时、大强度曝气,其出水CODMn和UV254的去除效果较好。高臭氧投加量时,增加曝气接触时间可以提高臭氧对有机物的去除率,出水效果较好。在活性炭投量为10 mg.L-1,pH为8.3,水温为45℃,臭氧投加量为3 mg.L-1时,活性炭对黄河水的吸附效果较理想。臭氧氧化对黄河水中TOC的去除效果低于CODMn和UV254的去除效果,当臭氧投加量为8 mg.L-1时,TOC去除率才为10%。但是臭氧投加量为5 mg.L-1,BDOC提高了80%。因此臭氧氧化可以大幅度提高原水的可生物降解性,为后续生物处理提供有机营养物质条件。Ozone and activated carbon were used to treat the Yellow River water.The oxidation efficiency of organic pollutants was analyzed in different concentrations of ozone.A self-designed static reaction system was established,two ways to control the ozone dosage.The result showed that with doses of ozone between 1 mg·L-1 and 5 mg·L-1,the removal rates CODMn from 8% increase to 20%,did not change significantly more this.The removal rates UV254 from 9% increase to 36%,which lots of organic compounds can be removed.When ozonation dose was 1～2 mg·L-1,the short-term,high aeration intensity,removal rates of CODMn and UV254 were better.But increase ozonation dose,the longer aeration time was useful for romovel of organic pollutant,effectiveness can be increase.Under the condition that,the dosage of activated carbon was10 mg·L-1,the pH value was 8.3,the temperature was about 45 ℃,the doses of ozone was 3 mg·L-1,the adsorption capacity was stronger.It was indicated from the experiment that when the ozone dosage was 8 mg·L-1,the removal rate of TOC was 10%,far lower than CODMn and UV254.However the ozone dosage was 5 mg·L-1,BDOC increased by 80%.Therefore,the ozonation can improve biodegradability of water,provide the follow-up biological treatment with the conditions of organic nutrients.
