As private sewage treatment facilities in Korea are constantly concerned about the distribution and poor construction of defective products, minimum standards for each unit process applicable to the planning and design of sewage treatment facilities are deemed necessary. The problems and requirements of the analysis results of the operation status discussed in this study are as follows. 1) Strengthening education of supervisor of private sewage treatment facility. 2) Poor operation and management of Sewage treatment facilities. 3) A mandatory review of sewage treatment facilities for less than 2 ㎥/day of facilities other than sewage treatment zones. 4) Necessity of management of sewage treatment facility in feedstocks. 5) As a result of the technical review, Improvement plans for Ineligible facility are needed. It is also necessary to prepare a guidebook for design construction and maintenance by investigating and analyzing guidelines and data related to domestic and foreign private sewage treatment facilities.

광주시 관내 폐수배출시설 방류수 6지점과 대형 건축물 오수 처리시설 방류수 4지점 및 중수 처리 재이용수, 건물 옹벽 지하수 2지점의 수질을 분석하여 중수로써 재이용 가능 여부를 조사한 결과 폐수 배출시설 방류수의 경우 조립금속제품 제조시설, 축전지제조시설 및 타이어제조시설이 대체적으로 중수도의 수질기준을 만족하고 있어 현재의 방류수를 그대로 중수로 이용 가능하리라 판단된다. 오수 처리시설 방류수의 경우 4지점 모두 유기물질은 물론 색도, 탁도 등 대부분의 항목이 중수도 수질기준을 초과하여 현재의 방류수 자체를 중수로 사용하기는 불가능 할 것으로 판단되며, 이들 방류수를 중수로 재이용하고자 한다면 모래 여과조나 활성탄 여과조, 소독시설 등 중수 처리시설을 설치하여야 할 것으로 판단된다. 오수처리시설 방류수를 중수 처리하여 재이용 하고 있는 중수의 경우 대부분 중수도의 수질기준을 만족하였으나, 색도와 탁도, 대장균군의 경우 일부 상당히 불안정한 수질을 보였으나 현재 화장실 세정수로 이용하고 있는데 색도 외에는 별다른 문제가 없는 것으로 나타났고, 대형빌딩 옹벽에서 흘러나오는 지하수의 경우 일반세균과 질산성 질소를 제외하고는 모두 먹는물 수질기준에 적합한 것으로 나타나 현재의 지하수를 그대로 청소용수나 화장실 세정수 등의 중수로 재활용해도 충분하다고 판단되며, 활성탄 여과조와 소독 시설 등의 추가시설을 갖춘다면 먹는 물로도 사용이 가능하리라 보며, 수량적인 측면에서도 1일 발생량이 100~400톤 이상이므로 충분히 경제성이 있을 것으로 판단된다.

This study was conducted to prepare a plan for the operation and improvement of excretory treatment facilities in Seoul, where the amount of excrement is expected to continue to increase due to the increase in the installation of septic tanks, a private sewage treatment facility. As a result, there are problems due to the lack of treatment capacity and increase in the amount brought in. To improve this, it is necessary to expand the overall excretory treatment facility, adjust the area of some facilities, reduce the amount of excrement through the realization of excretory units, and reduce the amount of excrement due to the change of the type of sewage treatment facility.

Post-Environmental impact investigation(Post-EII) plays an important role in investigating and reducing the environmental impacts of construction operations in South Korea. To date, it has been estimated that the results for Post-EII showed the low reliability; however, understanding those reliability has rarely been studied. We investigated the effect on water qualities by construction operations of the quarry mine, training center, and golf club in South Korea. In addition, the results of water quality analysis in this study were compared and analyzed with those in Post-EII. Treated wastewater in a quarry mine showed high concentrations of biochemical oxygen demand(BOD), suspended solid(SS), total nitrogen(T-N), and total phosphorus(T-P). Compared with the water quality results between this study and Post-EII, the concentrations of BOD, SS, T-N, and T-P in the treated wastewater were higher than the interquartile range(IQR) as well as the range of the results from minimum to maximum in Post-EII(p<0.05). The concentrations of BOD, SS, T-N, and T-P in treated wastewater were high under constructions in a training center. The concentrations of BOD and SS exceeded the consultation standard for the treated wastewater. These concentrations showed the significant difference with the IQR and the range from minimum to maximum of the water quality results in Post-EII(p<0.05). Therefore, the management and monitoring for water quality should be conducted in the treated wastewater by of construction operations. In addition, the alternative to enhance the reliability for the water quality results should be sought in Post-EII.
