  • 국가적으로 운영되는 국가산업단지는 악취를 포함한 유해 대기오염물질이 다량으로 배출되어 악취 피해의 민원이 증가하면서 이에 따른 악취 저감 대책 및 규제대책 마련에 관심도가 높아지고 있다. 특히 악취는 여러 가지 성분이 복합적으로 존재하고 후각에 의해 인지되기 때문에, 감각공해로서 후각의 개인적 차이와 기후와 지리적 여건에 따라 그 피해 정도가 달라지게 된다. 이러한 악취의 특성을 고려하면, 정량적으로 산출하기가 매우 까다롭고, 그에 따른 악취규제대책 마련도 매우 복잡할 수 있다. (중략)

  • In this study, by using a Effective Microorganisms Brewing Cycle, it confirmed the purification effect of pollutants that are adsorbed on the basins stench removal and retarding soil. On the basis of on-site application test, a soil decontamination system will be suggested. Using a Effective Microorganisms Brewing Cycle, the odor concentration is reduced 2.5 times than that of natural purification treatment method. It was measured and found that the quality of the pore water discharged from the soil is improved. In addition, it was found that a composite of copper and lead with the fermentation microorganisms adsorbed on soil particles from the surface of the stirred experiments lagoon mixed soil is reduced to 65% and 66%, respectively, The TPH organic component was confirmed that the reduction effect of 85%. Restoration of reservoir contaminated soils using the effective microorganism brewing cycle needs to be more developed and implemented as a long-term purification system. This study may be a good reference of developing more complete microorganism brewing system which will efficiently reduce the odor and soil contamination based on optimal stirring and mixing ratio of the compound solutions and contaminated soils in reservoir.

  • This study was carried out to investigate the effect of enzyme complex on odor emission from swine slurry and the process of making swine liquid manure. Ammonia and hydrogen sulfide concentrations were significantly decreased by using the enzyme complex of liter per ton level of liquid swine slurry in the manure storage tank according to the time. Characteristics of liquid swine slurry were affected by the enzyme complex, total nitrogen and ammonia nitrogen contents were reduced compare with control. Ammonia and hydrogen sulfide concentrations in the finishing pig building and offensive odor compound on the boundary line of swine farm were significantly decreased by spraying in swine finishing building. In conclusion, the results obtained from this study suggest that using the enzyme complex of liter per ton level of liquid swine slurry for making liquid swine manure may improve the quality of swine liquid fertilizer and reduce odor emission. Also farm scale enzyme complex treatment may improve air quality in finishing pig building and deduce offensive odor compound of swine farm.

  • This study was conducted to find means to reduce the foul smell emitted from chicken manure. Rice water was inoculated with Lactobacillus sakei and then examined to determine the bacterial survival rates during storage, and whether fermentation had occurred. Rice water was an excellent medium for the growth of L sakei, given that a viable cell count was maintained for 15 days during storage at $4^{\circ}C$ and decreased slightly thereafter. Furthermore, microorganisms in chicken manure were separated and 14 species were identified. The antibacterial activity of an L. sakei supernatant against the identified microorganisms was measured using the agar diffusion method. The growth of 11 out of 14 species was inhibited, and only Corynebacterium variabile, Enterococcus faecium, and Raoultella ornithinolytica survived. Rice water was fermented by inoculation with L. sakei and mixed with chicken manure, and the quantities of ammonia, ethyl mercaptan, and hydrogen sulfide were measured after 48 hours. Emissions of ammonia and ethyl mercaptan were reduced significantly.

  • 악취물질은 발생원이 다양하고, 극미량으로도 악취를 발생하게 되므로 어느 정도 저감하더라고 그에 따른 개선효과를 거두기 어려울 뿐만 아니라, 됐게 감지되므로 많은 민원을 야기 시키고 있다. 근래에는, 전체 환경관련 민원중 악취와 관련된 민원이 20% 정도를 차지할 정도로 많은 비중을 차지하고 있으며, 해를 거듭할수록 민원 발생건수가 증가하고 있는 실정이다. (중략)

  • 현재 우리나라는 공단지역에서 발생하는 VOCs(휘발성 유기화합물) 및 악취의 처리에 대한 연구개발 및 기존기술이 매우 취약한 실정이며, 일부 화학공장에서는 축열식 연소장치나 촉매연소장치를 설치하여 운전하고 있지만, 유지비(보조연료비)가 많이 소요되어 제대로 가동하지 못하는 경우가 있다. 대부분 제조업체의 경우, 활성탄 흡착탑을 설치하여 운영하지만, 화학공장에서 발생하는 포름알데히드, 스티렌 등과 같은 일부 물질은 흡착탑 내부에 타-르 같은 물질이 침적하고, 활성탄에 의한 흡착율이 낮으며, 저농도에서도 악취가 발생하므로 이러한 저농도 VOCs 물질들의 처리에 Biofilter를 적용하여 처리가능성을 조사하였다.(중략)

  • The usage of efficient microorganism (EM) is increasing in concern for server purposes including odor removal during carcasses degradation. In this study, we have studied the type of soil and its effect on efficient microorganisms for the removal of odorous gases during buried carcasses degradation in lab-scale reactor. The carcasses are buried in the reactor with various soil types such as normal soil, 20% sandy and 20% clay soil with the efficient microorganism KEM. The efficient microorganisms KEM have the ability to stabilize the degradation of carcasses of the burial site. We have focused on the analysis of odorous gases such tri-methylamine (TMA), hydrogen sulfide ($H_2S$), methyl mercaptan (MM), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), carbon dioxide ($CO_2$), and methane ($CH_4$) along with the changes of microbial community changed during complete degradation of buried carcasses for a year. The results suggested that the 20% sandy soil contain lesser level of $H_2S$ and MM (0.09 and 0.35 mg) but 20% clay has higher nitrogen compound removing effect and leave only less amount of ammonia and TMA (0.31 and 2.06 mg). The 20% sandy soil also has the ability to breakdown the carcasses more quality compared with other types of soil. Based on the data obtained in this study suggesting that, the use of 20% sandy soil can effectively control sulfur compounds whereas 20% clay soil controls nitrogen compounds in the buried soil. Depending on the type of the soil, the dominant of microbial communities and the distribution was change.

  • 시화, 반원공단은 수도권의 공장 분산정책에 의해 형성된 다양한 업종의 영세한 중소기업에 의해 구성된 공단이다. 서해안과 인접한 지역에 위치하며, 풍하방향에 배후 주거단지가 입주하면서 악취민원이 지속되고 있는 지역이다. 이러한 악취현상에 대응하기 위해 관련부처와 연구기관에서는 다양한 방법으로 악취현상의 규명노력과 저감대책을 시행하여 왔다 지금까지의 대부분의 악취 측정에 관한 연구는 주요 악취 발생지점에서의 악취원인물질을 규명하려는 노력에 집중되었고, 이 지역 악취현상의 공간적인 분포를 파악하기 위한 자료는 부족하였다.
