Recently to control refractory dissolved organic matter which is recognized as a problem of water quality management in public water area, it is strongly requested the strengthening of process for T-P which is the growth limitation factor. So we have researched the characteristic of filteration through composite filtering system by direct filteration system adapted floating media to treat phosphorus treatment of second sewage disposal water and particle pollutant. In this research we could confirm the increase of phosphorus removal efficiency by glowing bigger particle floc than existing filteration process through slow mixing of composite direct filteration system. And also as a result of an experiment of filteration efficiency for each coagulants, PACl was approved as the most appropriate coagulants.

인구 500명 미만의 지역에 Pilot-plant를 이용하여 실 Plant의 적용 가능성을 알아보기 위해 실험한 결과 Type1 시설은 Type 2단계 시설보다 근본적으로 보다 나은 처리능력과 특히 높은 안정성을 보여 주었다. 실험 중 Type 1은 BOD5값은 8 mg/L보다 작게, COD값은 56 mg/L보다 작게 유지될 수 있었다. 또한 똑같은 조건에서 온도가 3℃이하일 때 거의 완전한 질산화가 이루어 졌으며 질소 제거율이 평균 45%, 최대66.7%의 제거율을 나타내며 인 제거율은 평균 33%, 최대 62.9%에 달했다. The study was carried out to investigate the Pilot-plant of a container-type biological process of two types of about 260 people residence from December, 2003 to June, 2004. The type 1 facilities showed better process ability especially on the high stability and fundamentally better than those of Type 2 step facility. The type 1 showed high COD and BOD5 removal ability during experiment. The sewage outlet BOD5, the COD is able to keep at 56 mg/L and at 8 mg/L in a mixed sample inspection for 24hours. When temperature was 3℃ degrees or below, A nitrogen removal rate was reached at an average of 45% with the maximum removal rate of 66.7%. Phosphorus removal rate was also reached at an average of 33% with the maximum removal rate of 62.9%.

When an anaerobic activated carbon fluidized bed biofilm reactor is employed for wastewater treatment, a reserve space is required above the fluidized bed to prevent the loss of media, and wastewater treatment efficiency may be affected by the attached and suspended biomass in the reserve space. Therefore, experiments were performed by increasing stepwise the organic loading rates(OLR) of two reactors with and without a reserve space from 2 to 16㎏ COD/㎥-day. Results of the research showed that treatment efficiencies of the reactors were almost similar until the OLR reached 8㎏ COD/㎥-day. At higher OLRs, however, the effluent quality of the reactor without a reserve space was worse than the one with a reserve space. This is due to sloughing-off and washing-out of the biomass in the reactor without a reserve space, but the reactor with a reserve space maintains more biomass because of the attached growth on the inside surface of the reserve space. Therefore, a reserve space for prevention of media loss in an anaerobic activated carbon fluidized bed biofilm reactor would provide an increase in treatment efficiency at high OLRs.
