摘要：

The objective of this study is to evaluate removal of DOC and THMFP during long term operation of an ozonation-biological activated carbon (BAC) process. A pilot scale plant with raw water in an eutrophic reservoir for drinking water supply was operated for 910 days. High DOC and THMFP removal were maintained at 36% and 57%, respectively, in the ozonation-BAC process even after saturation of BAC by DOG. DOC and THMFP removal by ozonation were only 8% and 24%, respectively. High DOC and THMFP removal after saturation was due to the increase in biodegradable DOC by ozonation from 7% to 32% and the subsequent biodegradation by bacteria attached on BAG. Although water temperature changed in the range from 5 to 30 degrees C, seasonal changes in DOC and THMFP removal were not observed in the ozonation-BAC process.
