Biological enhanced treatment and send filtration are established being operated to remove nutrients and MBAS(Methylene Blue Activate Substance) in the most of Waste Water Treatment Plant(WWTP) in Korea. However, untreated synthetic detergents and nutrients which directly run into the water system present an unpleasant view because of the foam, taste and odor generating filamentous periphytic algae and interrupting self-purification in the stream. Therefore, this research was enforced to know the MBAS removal efficiency of the sand filtration about G WWTP which reuses effluent as urban stream management water. As a result, the maximum removal efficiency using sand filtration was 63% after 24 hours and particularly 30% after 2 or 4 hours which turned out to be not that effective. In conclusion, It is recognized that other methods of MBAS removal and a research will be needed which reuse effluent as urban stream management water from now on. Because the MBAS removal with sand filtration is insufficient with economical efficiency from the fact that it needs long hours for a sand filtration treatment and the removal efficiency was almost below the expectation.

가축 사육시설에서 배출되는 축산폐수는 도시하수와 달리 발생량에 비해 오염부하량이 대단히 크므로 수질오염의 주범일 뿐만 아니라 처리에도 어려움이 많아 축산폐수를 수거하여 전문적으로 처리하는 공동처리장에서도 현재 만족 할만한 처리효과를 기대하기 힘든 처지에 있다. (중략)

This paper is studied on waste water maintenance management system for Integrated computing environment. This computing environment consist of Waste-Water Maintenance Management and GIS(Geographic Information System). This system can be developed by constructing Database which is set of rules occurring while management work of waste water system is processed. This system will help person who has responsible for making decision. Objective of such computing environment is providing efficient working environment for waste water facility management. Especially we analyzed problems of existing waste water maintenance management. We carried out efficient management of water facility and it will provide solution for major decision making work with low cost using Waste-Water Maintenance Management System
