공업지역 강우유출수의 PAHs 유출 특성

Abstract

The purposes of this research are to grasp physical characteristics of sediments during the dry season, grain-size distribution, accumulation quantity, total content of organic materials and concentration distribution characteristics of PAHs and runoff concentration characteristics of polycyclic aromatic hydrocarbons compound of rainfall runoff water and PAHs behaviors of early rain treatment facility during the raining season on road surface of industrial area among the several urban spaces and provide basic data for management of PAHs of first rain treatment facility in the future. For the selection of investigation points, 4 points including lots of vehicle floating and particular building were selected during the drying season and southwestern drainage gate of SP industrial complex was selected during the raining season in 336,300㎡ of pure drainage area of SP industrial complex in J city. As a result of quantitative analysis on PAHs compound detected by equipment analysis, 8 items were detected among the 16-PAHs. Vehicles are driven the most actively in industrial area, so pyrene was the highest in all of areas. As a result of quantitative analysis on PAHs in rain runoff water, lots of dying factory, fabric, coal using factory, etc. are located in selected point, so Anthracene was high among the 8 items detected. Thoroughly, there was not a big change by time. For the relations among the rainfall, days of non-rainfall and PAHs, it's still difficult to judge that days of non-rainfall are related to the concentration of PAHs.
