The water quality in biological pretreatment and succeeding tr eatment process in running have been investigated to understand the effect of bi ological treatment on organic removal and the influence on the succeeding treatm ent process. It is found that due to the metabolism product dissolves in water, organics in the biological process treated water increases,resulting in decrea se of removal efficiency in the succeeding treatment process. The molecular weig ht distribution of the effluence water is determined and found that microbial me tabolism product could produce a lot of disinfection by-products. The biological process could not mitigate the mutagenicity.
