Abstract
Based on our studies on high-rate oxidation ponds(WANG, 1985, 1986, 1987 and 1988) and biofilm reactors with fibrous carriers(WANG, and SUI, 1986), the 'extended aeration submerged biofilm process' (EASB) is put forward for nitrogen removal under subtropical climate, with the consideration of the quality and quantity of the sewage and the quality of the effluent along with some other factors; a lab-scale experiment was done to determine the feasibility and some technical parameters of the treatment process. Biofilm process differs from the activated sludge process in that the latter operates with the activated biomass suspended in the system, while it attaches to the carriers in the biofilm process, which means biomass grow and adhere to the surface of the carriers.
