研究臭氧化过程中,臭氧投加量、p H值和离子强度对可同化有机碳(assimilable organic carbon,AOC)生成量的影响.结果表明,臭氧投加量在1~5 mg·L~(-1)范围,AOC的生成量随着投加量的增加而增加,但过高的臭氧投加量(9 mg·L~(-1))反而导致AOC生成量下降.p H越高(6~9),AOC的生成量也越高.AOC的生成量随着离子强度的升高而下降.臭氧氧化强疏组分AOC的生成量最高,其次为弱疏,而极亲和中亲最低.研究发现,AOC的生成量与小分子有机物的SUVA有密切的关系,较低的SUVA产生较多的AOC. The effects of ozone dosage, p H value and ionic strength on the yield of assimilable organic carbon (AOC) were studied in the ozonation process. The results showed that the ozone dosage was between 1 mg · L-5 mg · L-1 -1), the amount of AOC increased with the increase of dosage, but the excess of ozone dosage (9 mg · L -1) led to the decrease of AOC production.The higher the value of p H 6 ~ 9), the higher the formation of AOC.The formation of AOC decreased with the increase of ionic strength.The formation of AOC in Ozonation strong-denatured component was the highest, followed by weakly sparse, The lowest.The study found that the formation of AOC and small organic molecules SUVA are closely related to lower SUVA produce more AOC.
