초록

업종별 수질오염물질 배출 목록은 산업폐수 배출시설을 인허가할 때, 해당 시설 또는 업종에서 관리해야 하는 배출 가능한 수질오염물질을 정확히 검토하기 위함은 물론이고, 오염방지시설의 설계에도 필수적인 가장 기초적인 자료이다. 본 연구에서는 우리나라 폐수배출시설 3개 업종을 대상으로 수질오염물질 배출목록을 작성하기 위하여 해당 사업장의 일반현황 및 처리시설 운영 등에 대한 기초자료 수집과 해당 사업장에서 배출하고 있는 산업폐수중 특정수질유해물질을 비롯한 수질오염물질에 대한 수질 분석을 수행하였다. 본 연구의 조사대상 업종별 수질오염물질 배출목록을 확정하기 위해서 정상적인 시설운영 과정에서 해당물질이 폐수중으로 실제 배출될 수 있는 개연성을 확인하였다. 이를 위해, 먼저 원폐수 및 최종 배출수의 시료 분석에서 검출된 모든 수질오염물질을 평가대상으로 하고, 검출되지 않은 물질은 대상에서 제외한다. 다음으로 이들 평가대상 수질오염물질에 대하여 제조공정상에서 사용하는 각종 원료, 부원료, 불순물 등에서 포함될 가능성을 확인하고, 여기에서 확인될 경우 수질오염물질 배출목록으로 확정한다. 본 연구에서는 3개 업종을 대상으로 하였으며, 석유화학계 기초화합물 제조시설은 조사대상 물질 42종 중 특정수질유해물질 16종을 포함한 31종, 기타 기초유기화합물 제조시설은 특정수질유해물질 14종을 포함한 30종, 화력발전시설은 특정수질유해물질 8종을 포함한 20종의 수질오염물질이 배출목록으로 확정되었다. 본 연구에서는 수질분석과 개연성 평가를 통해 보다 객관적이고 타당성 있는 업종별 수질오염물질 배출목록을 작성하였다.

Information on the lists of pollutants from industrial wastewater discharge are essential not only to specify the key pollutants to be managed in permission process but to design the treatment facilities by the dischargers. In this study, wastewater quality analysis was conducted for three industrial categories including the specified hazardous water pollutants. The general description of the wastewater occurrence, major sources, treatment facilities are also investigated to obtain integrated database on the pollutant inventories for the industrial categories. In addition Based on the analysis of raw wastewater and final effluent, the detected pollutant items are confirmed by analyzing their presence in the raw or supplement materials, the potential of formation as byproducts, and the possibility of inclusion as impurities. The three industrial categories include petrochemical basic compounds, basic organic compounds, and thermal power generation. The water pollutants emitted from petrochemical basic compound manufacturing facilities are 31 items including 16 specified hazardous water pollutants. Basic organic compound manufacturing facilities discharge 30 kinds of pollutants including 14 specified hazardous water pollutants. Thermal power generation facilities emit 20 pollutants, 8 specified hazardous water pollutants among them. These substances were decided as emission inventories of water pollutants finally through the probability evaluation. The compounds detected for each categories are screened through investigation on the possible causes of their occurrence and confirmed as the final water pollutant inventories.
