영어초록

The average BOD concentration was found to be about 269mg/L before a process innovation, but after the innovation, it became 30mg/L, which satisfied the effluent standard of 120mg/L. The removal effluent standard of 120mg/L. The removal efficiency was about 60～80%, and the concentration of the treated water was found th be low. after the process innovation, the average COD concentration was 29mg/L, and the CODmn removal efficiency became low to the level of about 65～76%, which was found lower than the effluent standard of 130mg/L.
After the process innovation the SS average concentration of the treated water was 13mg/L, which was lower than that before the innovation (32mg/L). By the activated sludge process innovation, the SS removal efficiency was improved to be 30～70%. The average concentration of total coliform before the process innovation was 6100 count/mL because an Activated sludge process only occasionally pass over the allowed standard(The average number of the total coliform of Activated sludge process treated water was about 8100 count/mL), UV disinfection process was introduced. after the introduction, the average number of the total coliform was 1800 count/mL, which satisfied the allowed effluent standard of 3000 count/mL.
