ASA법에 의한 질소, 인 제거 특성 = The Characteristics of Nitrogen and Phosphorus Removal in the ASA System

다국어 초록 (Multilingual Abstract)

Currently an increase in domestic sewage and industrial wastewater causes serious water pollution in Korea. To solve water pollution problems, Conventional activated sludge process(CASP) is generally used in wastewater treatment plant, but this process is so ineffective in nitrogen and phosphorus removal. Even if CASP is the major process, it must be improved instantly so as to remove nitrogen and phosphorus. Otherwise, the serious water pollution problems can't be resolved with existing process. Therefore, this study carries out an investigation by removal efficiency of BOD, COD, SS, T-N and T-P in the ASA system, which is advanced wastewater treatment system applied to domestic wastewater an apartment located in the water resource area.
The results of the study are followed ;
A removal efficiency such as BOD, SS and COD is over 90 percent, and that of T-N and T-P also over 85 percent and 90 percent respectively. Thus, it shows that the ASA system has an excellent treatment characteristic that is not expected in the exist in CASP.
