초록

본 연구는 고도처리공법을 적용하여 수년간 가동 중인 하수처리시설에 대한 운전현황을 측정 분석하여, 고도처리공법 적용의 적정성을 평가하고자 하였다. 단위공정별 처리효율은, BOD의 경우 1차침전지 35, 생물반응조 87, 최종방류수 48 %, T-N의 경우 1차침전지 18, 생물반응조 40, 최종방류수 25 %, T-P의 경우 1차침전지 23,, 생물반응조 38, 최종방류수25 % 등으로, 각 단위공정별로 양호한 처리효율을 나타내었다. 생물반응조 내의 미생물 관측 결과, 다양한 종류의 세균과 원생동물 및 후생동물이 관측되었고, 담체의 세균 부착기능이 안정적으로 유지되고 있음을 알 수 있었다. 최종방류수질은 BOD 5.5, COD 9.9, SS 4.6, T-N 11.8, T-P 0.99 mg/L으로 방류수 수질기준보다 낮은 양호한 수질상태를 나타내었다.

In this study, validity of wastewater treatment system with advanced treatment processes was evaluated by studying its operational conditions by applying the advanced treatment to the wastewater treatment system which was operating for last several years. Study indicated a fair result for the removal efficiencies of BOD, T-P, and T-N for each unit operation. BOD removal efficiencies for primary clarifier, bioreactor, final effluent are 35, 87, and 48 % respectively. T-P(T-N) removal efficiencies for primary clarifier, bioreactor, final effluent are 18(23), 40(38), and 25(25) % respectively. Further investigation of bioreactor showed that various microorganism such as bacteria, protozoa, and metazoa is present in the bioreactor, and the main function of the media, adhesion (adsorption) of microorganism onto the media, is stabilized. Final effluent quality was lower than the regulation, and BOD, COD, SS, T-N, T-P were 5.5, 9.9, 4.6, 11.8, 0.99 mg/L respectively.
