Reduced Loads Characteristics Comparison Between Permeable Pavement and Non-point Pollutants Treatment Facility
Kyung-Ik Gil, Hye-Sun Jeon
Abstract
This study aimed to provide basic data for permeable pavement application upon design and installation stages by analyzing the effect of permeable pavement used on the facility area rather than using non-point pollutants treatment facility upon development business in accordance with recent trend. To perform this study, the area of development target was separately applied as impermeable and permeable developments so as to compare and analyze the economics of cut pollution load and installation construction cost. Consequently, the processing amount and cut load of non-point pollutant sources are influenced much by permeable and impermeable developments, and it was turned out to be better to develop target river area as permeable area rather than installing non-point pollutants treatment facility of equipment type or natural type upon development to yield smaller discharge load. If we can prepare a countermeasure regulating impermeable area ratio to certain level to manage non-point pollutants upon development based on this result, we can minimize the source of pollution caused by the development.
Key Words: Non-point Pollutants Treatment Facility; Impermeable pavement; Permeable pavement; Reduced pollutant loads amount
요지
본 연구에서는 최근 추세에 맞춰 개발사업시 장치형 및 자연형등의 인위적인 비점오염저감시설이 아닌 시설지를 투수성 포장재를 사용할 경우 얻어지는 효과를 분석하여, 설계 및 시공시 투수성 포장재 적용을 위한 기초자료를 제공하고자 한다. 그 방법으로 개발시 대상지의 면적을 불투수성과 투수성 개발로 분리 적용하여 삭감오염부하량 및 설치 공사비의 경제성을 비교 분석하였다. 그 결과 비점오염원의 처리용량 및 삭감부하량은 투수성 및 불투수성 개발에 많은 영향을 받으며, 개발시 비점오염저 감시설을 장치형이나 자연형을 단독으로 설치하기 보다는 처리대상 유역을 투수성 지역으로 개발하는 것이 배출부하량이 적은것으로 나타났다. 이를 토대로 개발시 비점오염의 관리를 위해 불투수율 면적비를 일정수준으로 제한하는 대책을 수립하면 개발에 따른 오염원의 최소화가 가능할 것으로 생각된다.
핵심용어: 비점오염저감시설; 불투수성 포장재; 투수성 포장재; 삭감오염부하량
