본 연구는 축산지역 비점오염원 저감시설로서 바이오갈 대와 바이오여재를 이용한 저영향개발 (LID)공법이 적용된 처리수에 대한 생태독성 평가를 수행하였다. 식생수로와 인 공습지를 이용한 유입식 파일럿 플랜트와 침투도랑을 이용 한 회분식 파일럿 플랜트를 제작하여 축산폐수처리장 시료 를 대상으로 생태독성 시험을 수행하였고 처리 전 후의 오 염원 저감율과 생태독성도와의 연계성을 평가하였다. 각 파 일럿 플랜트는 바이오갈대와 바이오여재를 이용한 바이오공 정으로 제작하였으며 대조군으로 일반갈대와 일반여재를 이 용한 일반공정을 제작하였다. 본 연구결과, 유입식과 회분식 파일럿 플랜트 모두 일반공정보다 바이오공정이 적용된 경 우 유출수의 COD, TN 그리고 TP 저감 효율이 더 높았다. 또 한 HRT 24시간 LID 공법을 적용 후 물벼룩 독성도는 상당 히 낮아졌으며 특히 회분식 파일럿 플랜트가 독성저감에 효 율적인 것으로 나타났다. 바이오갈대와 바이오세라믹 등으 로 구성된 LID 공법은 비점오염원 저감시설뿐만 아니라 가 축분뇨 정화시설과 연계한 후속처리공정으로 생태독성을 고 려한 수질관리에 효과적일 것으로 예상되며 향후 오염원과 독성도를 동시에 저감할 수 있도록 LID 공법 최적화 연구가 필요할 것으로 판단된다.
Abstract
This study evaluated the ecotoxicological properties of livestock waste water treated by a LID (Low Impact Development) system, using a mixture of bio-reeds and bio-ceramics as suitable bed media for a subsequent treatment process of a livestock wastewater treatment plant. The relationship between the pollutant reduction rate and the ecotoxicity was analyzed with the effluents from the inlet pilot plant, with vegetated swale and wetlands and the batch type of an infiltration trench. Each pilot plant consisted of a bio process using bio-reeds and bio-ceramics as bed media, as well as a general process using general reeds and a bed as a control group. The results indicated that, after applying the HRT 24 hour LID method, the ecotoxicity was considerably lowered and the batch type pilot plant was shown to be effective for toxicity reduction. The LID method is expected to be effective for water quality management, considering ecotoxicity by not only as a nonpoint source pollution abatement facility but also, as a subsequent treatment process linked with a livestock manure purification facility. It is necessary to take the LID technic optimization study further to apply it as a subsequent process for livestock wastewater treatment.
