소수계 유역 인공습지에서 식생 밀도 차이에 따른 영양염류 제거효율
고지연,강항원,이재생,김춘송,Sakadevan,K.,Bavor, H. J. 한국환경농학회 2003 한국환경농학회지 Vol.22 No.4
호주 시드니 인근 도·농 복합 소도시로부터 발생하는 비점오염원을 처리하기 위하여 설치된 Plumpton park와 Woodcroft park 인공습지의 처리효율을 살펴본 결과, 수생식물의 밀도가 증가하고 식생이 안정된 Plumpton park 인공습지에서 T-P의 26.2%, T-N의 38.3%, 식생분포가 안정적이지 않은 Woodcroft park에서 14.0%와 20.2%가 각각 제거됨으로서 식물체 근권 미생물에 의한 T-P 및 T-N의 제거 효율이 상당히 큼을 알 수 있었다. 또한 T-N와 T-P에 비하여 NH₄-N, NO₃-N, PO₄^(-3)의 제거율이 높았던 것은 무기태 형태의 영양염류가 식물 및 미생물에 더 쉽게 이용되었기 때문으로 생각된다. 이상의 결과로 볼 때 인공습지에서 식물체와 근권 주위 미생물에 의한 염류제거는 인공습지가 설치한지 오래되었을 때도 효과적이었고, 또한 인공습지는 무기태 영양염류의 제거효율이 더욱 높았으므로 무기화학비료 등의 용탈이 일어나기 쉬운 농경지 비점오염원으로부터 발생하는 수질오염의 개선에 이용할 수 있는 경제적이고도 효율적인 system으로 고려되었다. This study was conducted to evaluate effects of 2 constructed wetlands with different vegetation states (Plumpton park wetland and Woodcroft park wetland) for reducing non-point source pollution from small watershed consisted of residential and agricultural area in suburban district of Sydney, Australia. The total nitrogen and phosphate removal efficiency of Plumpton park constructed wetland, composed of stable and dense vegetation, were 38.3% and 26.2% and Woodcroft park constructed wetland having still poor vegetation due to the short time to settle down transplanted plants after construction, showed relatively low removal efficiency of 20.2% and 14.0%. The removal efficiency of inorganic nutrients such as NH₄-N, NO₃-N, PO₄^(-3) were higher than total nitrogen and phosphate because plants and microorganisms in rhizosphere of constructed wetlands took up inorganic nutrients shortly. According to the type of wetland inflow, the nutrients removal efficiency of storm water flow was lower than base flow.
보릿짚의 수분함량 및 수확시기가 소각시 대기오염물질 발생에 미치는 영향
고지연,강항원,이재생,김춘송,박성태,김복진 한국환경농학회 2004 한국환경농학회지 Vol.23 No.2
영남지방 벼-보리 이모작답에서 가장 널리 시행되고 있는 보릿짚 처리방법인 소각이 대기환경에 미치는 영향을 소각시 발생하는 온난화가스, 대기오염가스 및 분진발생량을 중심으로 살펴보았다. 보릿짚 소각시 온난화가스 발생량은 CO₂376.8, CH₄ 1.56, N₂O 0.05 kg/10a 로서 CO₂의 발생량이 가장 많았으며, 대기 오염가스 중에는 유기물의 불완전 연소시 배출되는 CO발생량이 28.8 kg/10a로서 가장 많았다. 그 외 SO₂ H₂S, NH₃, NO등의 질소 및 황 함유 유해가스도 소량 발생되었고 발생된 PM 10 분진의 대부분은 인체에 미치는 영향이 PM 10보다 큰 PM 2.5로 이루어져 있었다. 또한 수확시기가 빠르거나 수분함량이 높은 보릿짚일수록 온난화가스 및 대기오염 가스의 발생량이 증가하고 소각 연기내 PM 10 분진중 PM 2.5의 미세분진 비중이 높았다. 수확적기로 알려진 출수 40일 이후의 보릿짚은 출수 후 40일된 보릿짚 소각시 발생하는 대기오염가스 발생량과 큰 차이가 없었다. This study was carried out to determine impacts of burning of barley straw produced from rice-barley double cropping paddy field on air quality by investigating emissions of greenhouse gases (CO₂, CH₄ and N₂O), air pollution gases (CO, SO₂, H₂S, NH₃ and NO) and particulate matters (PM 10 and PM 2.5). When the barley straw at a rate of 4.5 t/ha was burned at open status, the emitted GHGs amounts were CO₂ 376.8 kg/10a, CH₄ 1.56 and N₂O 0.06. The amount of CO emission was the largest among air pollution gases. These results showed that the range of 45~55% of total C in barley straw was emitted as CO₂-C, followed by CO-C (6.4~5.9%) and CH₄-C (0.5~0.7%). As far as moisture content in barley straw is concerned, the higher moisture content that the barley straw contains, the larger amount of air pollution gases and the higher portion of PM 2.5 in PM 10 were emitted when it burned. In case of harvesting time of barley straw, emission amounts of greenhouse, air pollution gases and PM 2.5 portion in PM 10 had tendency to increase when earlier harvested barley straw was burned.
