摘要
实验目的在于对溶解性有机物进行分类及考察,研究臭氧氧化影响四种溶解性有机物:1.可生物降解不可吸附;2.可生物降解可吸附;3.可吸附不可生物降解;4.不可吸附不可生物降解。(NA&BDOC、B&ADOC、NB&ADOC、NRDOC)的因素及趋势。实验结果表明臭氧不能同时去除四种溶解性有机物,而是影响它们所占比例,使可生物降解性有机物增加,可吸附性有机物减少。根据实验结果可优选出后续生物活性炭净水效果的最佳的臭氧投加量和停留时间。实验结果可为工程设计提供有益的参考价值。
The objective of this study is to clarify the dissolved organic carbon（DOC）, and research how ozone does effect the four kinds of DOC（NA＆BDOC,B＆ADOC,NB＆ADOC ,NRDOC）. The result showed that the four kinds of DOC can not remove simultaneity by ozonation, but change their ratio （increase BDOC and reduce ADOC）. The optimized dosage of ozone and contact time can be choosed with the results. These results could provide valuable reference for project design. Keywords DOC ozone dose ozone contact time BDOC ADOC
