간접폭기형 침적생물여과장치(INSUB)를 이용한 오수처리 특성
허목,강진영,김광진,Huh, Mock,Kang, Jin-Yuong,Kim, Gwang-Jin 유기성자원학회 2003 유기물자원화 Vol.11 No.2
본 연구는 오수중의 유기물 및 질소 인의 동시제거를 위한 오 폐수 고도처리장치인 간접폭기형 침적생물막여과장치(Indirected Aerated Submerged Biofilter : INSUB)를 개발하기 위하여 실험실적 모형실험을 수행하였다. INSUB에서 오수를 처리함에 있어서, HRT 18시간, 공탑속도 42.5m/hr, 충전율 40%인 경우가 실제로 경제적인 효율을 고려하였을 때, 가장 효율이 좋았다. 각각의 제거효율을 살펴보면, $COD_{cr}$, 90.6%, $COD_{Mn}$ 85.3%, $BOD_5$ 95.0%, T-N 52.3% 그리고 T-P 56.8%로 나타났다. 질소 인의 고효율처리를 위해서는 전탈질공정에 의한 산화질소의 제거를 위해 무산소, 호기조의 조합 등에 의한 system의 일부 다단화가 필요함을 확인할 수 있었다. This study was carried out to develop INSUB(Indirected Aerated Submerged Biofilter) which can remove organics, nitrogen and phosphorus with an advanced treatment system. The results were as followed in laboratory model experiment. As for treatment of sewage, when economical efficiency was considered in practice, the highest removal efficiency was at 18hr of HRT, 1.017m/hr of superficial velocity and 40% of media packing ratio. Each removal efficiency for $COD_{cr}$, $COD_{Mn}$, $BOD_5$, T-N, and T-P was 90.6, 85.3, 95.0, 52.3 and 56.8%. To remove the nitrogen and phosphorus With high efficiency, first of all, denitrification have to be completed, then uptake of phosphorus have to completed. Therefor, mixture of anoxic and aerobic reactor was necessary for the high removal efficiency of nitrogen and phosphorus in INSUB.

산화·환원 전위 변화에 따른 도시폐기물 매립지 침출수의 수질 변화 특성
허목,Huh, Mock 유기성자원학회 2001 유기물자원화 Vol.9 No.1
미분해 유기물이 다량 존재하는 매립초기에 발생되는 침출수는 미생물에 의한 혐기성 소화가 진행됨에 따라 침출수중의 유황성분이 유황환원세균 등에 의해 황화물이온으로 환원되고, 이것이 금속이온의 양보다 과잉으로 많을 경우 sol화된 금속황화물이 되어 침출수를 검은색으로 변색시킴을 알 수 있었으며, 이들은 검은색의 입자상 물질을 형성하여 침전물을 생성함을 알 수 있었다. 따라서 이와 같은 침출수 처리를 위해 과잉의 황화물이온을 당량이상의 금속이온과 반응시킨다면 부동태화시킬 수 있다는 향후의 경제적 효율적인 처리를 위한 중요한 가능성을 확인할 수 있었다. It can be known that from leachate generated in the initial stage of landfill there are a lot of undecomposed orgainc materials, its sulfur component reduces to sulfide ion by sulfur reducing microorgarnisms as an anaerobic digestion proceeds, the sulfide ion makes the leachate discolor to black by forming metal sulfide sol, on condition that much more equivalent of sulfide ion than that of metal ion is present, and the metal sulfide sol can be generated to the precipitates by forming black-colored particulates. Therefore, we can confirm the important possibility for the economic and efficient treatment of leachate that it can be passivated, provided that much more equivalent of sulfide ion is present in the reaction of sulfide ion and metal ion.

생물막 여과법에 의한 육상 수조식 양식장 배출수 처리 (1) - 최적여재의 선정을 위한 기초적 실험연구 -
허목(Mock Huh),강봉래(Bong Rae Kang),이용두(Yong Doo Lee) 한국수처리학회 1995 한국수처리학회지 Vol.3 No.2
Todays, The coastal environmental contamination caused by the waste water discharged from inland aquaculture have surfaced as a important issue and the biofilm filtration system was used to effectively, economically and steadily treatment. To selection of optimal media, each type of media comparatively analyze physical characteristics and filtration treatment efficiency. The results of experiment were as follows; 1. The physical characteristics of the porous plastic media used in this research represented specific gravity, 0.59; roundness, 0.73; porosity, 75.0; permeability coefficient, 588㎝/min; and specific surface area, 9.92×103㎥/㎡; and that this media was the most suitable to the biofilm filtration process, as compared to sand or scoria media. 2. It has been verified through filtration characteristic comparison tests that plastic media offer the quickest filtration tunes, and best SS and COD removal characteristics. 3. At a filtration rate not exceeding 400m/day, major pollutants such as SS and COD were effectively and steadily removed and, in the case of limiting headloss being 0.6m, continuous filtration time was approximately 28 hours. 4. The experiments showed no significant difference resulting from filtration rate variation with respect to the amounts of total SS and COD removed per unit filtration area during thu effective filtration at different filtration rate. The total average amounts of SS and COD removed per unit volume were calculated at 8.81㎏SS/㎥ and 2.06㎏COD/㎥, respectively.

본 연구는 실험실 규모의 회분식 반응기로 음식물쓰레기와 돈분을 퇴비화하였으며,수분,C/N비 및 비중 조절재로써 톱밥과 코코덧 피트를 사용하였다. 첨가재로 톱밥만을 이용하여 생산된 퇴비와 톱밥과 코코덧 피트를 이용하여 생산된 퇴비를 비교하여 볼 때,전자가 후자보다 감량율과 분해율이 약간씩 높게 나타났다. 이는 코코덧 피트가 톱밥보다 보습력이 뛰어났기 때문이며 . 초기 수분량이 낮고‘ 통기성이 좋아 적정의 111중조절이 가능하여 호기성 발효를 촉진할 수 있었다. 음식물쓰레기만에 의한 퇴비는 그 비료성분이 부산물 비료의 기준을 만족시킬 수 없으며. 따라서 음식물쓰레기와 돈분을 동일 비율로 흔합하여 양질의 퇴비를 생산할 수 있었다. CEC값은 평균적으로 63.8me/100g 이었다. 톱밥의 높은 C/N비 때문에 퇴비화 초기의 C!N비는 적절하게 조절되었다. C!N비 ()40)가 높을수록 감소율이 컸으며,퇴비화하는 동안의 C/N비는 점점 향상되었다. This study was performed about composting in a batch reactor of laboratory scale using garbage waste and swine waste. Sawdust and coconut peat were materials to control optimum moisture. Cη-J ratio and specific gravity in the study. Comparing compost using only sawdust with compost using sawdust and coconut peat. the latter was higher at reduction rate 없ld decomposition rate. Coconut peat was accelerated aerobic fermentation. because it had moisture holding ability, initial moisture was low. ventilation was good and control of optimum specific gravity was possible. Compost by only garbage waste was under standard of manure. but mixtures in same proportion of garbage waste and swine waste producted high quality compost. CEC value was average 63.8me/l00g. The initial C!N ratio of compost was re밍llated effectively because of high C/N ratio of sawdust. As the C이 ratio()40) was higher , reduction rate was higher. During the composting C/N ratio was improved more and more.
