摘要
对两家采用前臭氧-生物活性炭工艺,原水性质相差较大的水厂进行了有机物分布情况调查。结果表明,臭氧化对有机物结构有重要影响,基本上表现为大分子量的有机物被分解成较小分子量的有机物,大分子量有机物含量大,其被分解的数量也较大。经过臭氧氧化后,不管有机物组成如何,3 K～1 K范围内的有机物会有较大幅度的上升,<1 K的有机物上升不大,说明臭氧虽然是较强的氧化剂,也无法较为彻底的分解有机物,而且臭氧工艺基本不会改变水中有机物总量。
The investigation on the distribution of organic substances of two water works in C city.Both works adopt ozone-biology activated charcoal processing, but the original water quality is differnt.The result indicated that ozone has great influence on organic substances＇structure, and ozone truns the macro-moles ule organic matter into low malecular weight one; If the quantity of the macro-malecule was big, the decomposed quantity was big too.After ozone oxidation, no mater what the compose of organic substances, the organic substances between 3 k-1 k would be raising extently.〈1 k would raise little.h indicated that orone was a better oxidant, but can not decomposed drastically, and the ozone technics wouldn＇t change the total quantity of organic substances in water on the whole.
