박출재,이준걸 安東大學校 安東地域社會開發硏究所 1996 安東開發硏究 Vol.7 No.1
본 고는 안동시에서 발생한 고형폐기물의 발생현황을 참고문헌 및 현장조사를 통하여 조사 분석하여 그 처리대책을 검토하므로서 앞으로 안동시의 폐기물 처리문제에 참고가 되는 계기가 되고자 하였다. 1994년 현재 안동시·군의 년간폐기물 발생량은 85,775톤/년이고 인구 1인당 발생량은 평균 1.52kg/인·일 (시 : 1.56kg/인·일, 군 : 1.48kg/인·일)로서 전국평균 1인당 발생량 1.5kg/인·일을 넘고 있으며 이는 향후 시·군의 통합으로 인한 인구의 양적 팽창과 도시의 비대화로 인한 시민의 생활수준의 향상으로 더욱 증가될 것으로 예상된다. 때문에 앞으로 안동시의 효율적인 폐기물 관리를 위해서는 폐기물 발생량 및 질적 특성에 대한 상세한 조사가 이루어져 장기적인 안목을 가지고 대책을 세워나가야 할 것인 바 발생량 저감을 위한 시민의식의 전환, 소각장 건설, 음식물 쓰레기의 재활용 사업, 폐기물의 재활용 정책, 종량제의 효과적인 시행 등 폐기물에 대한 체계적인 관리 대책이 수립되어야 될 것으로 생각된다.

본 연구는 대구지역의 지하공간내 NO₂농도의 기본자료를 제시하기 위해 수행되었으며 여기에서 얻어진 측정자료들은 지하공간내 NO₂를 감소시키기 위한 일종의 지침으로서 NO₂ 배출원을 조절하기 위한 준비작업으로 제공될 수 있을 것이다. NO₂측정은 Yanagisawa 연구진들이 제안해온 간접적인 시료채취 방법으로 필터뱃지를 사용하였다. 시료채취 지점은 총 5개소이며 여기에는 3개소의 지하상가와 2곳의 지하주차장을 선정하였다. 시료채취기간은 1992년 11월에서 1993년 4월까지이며, 시료채취용 필터벳지의 노출시간은 48시간이다. This study was carried out to provide basic data of NO₂concentration at underground spaces in Taegu Area, by which a sort of guideline for the reduction of NO₂may be prepared for controlling the emission sources. The NO₂measurements was performed using a filter badge method, which is a passive sampling technique purposed by Yanagisawa et al. A total of five sampling sites were selected ; three sites are underground arcades and two are underground parking lots. The sampling period was from November 1992 to May 93. The NO₂data measured were integrated for 48 hours.

25㎜ NSW-ring, pp.를 充塡한 充塡塔에서 암모니아 吸收에 의한 充塡物의 特性硏究
申恩才,朴出在,金彰昊 동아대학교 환경문제연구소 1995 硏究報告 Vol.18 No.1
This study was carried out to demonstrate the superiority of used packing in view of energy saving and efficiency of mass transfer, comparing with conventional packing. The results are as follows : 1. Owing to low pressure drop under high load, 25mm NSW-ring, pp. can cause energy saving. 2. The unique magnitudes of used packing are as follows : C_(G) = 5.78 m = 0.67 n = 0.46 3. Used packing can make high efficiency including energy saving because of low pressure drop per the number of transfer unit. To rate the characteristic of packing, it should be carried out that the measurement of pressure drop per packing height and per the number of transfer unit. This study demonstrated the superiority of used packing by caning out above experiment and could be used as basic reference for design and predicting efficiency of packing tower which is filled with same packing.

본 실험은 黃化水素 취기를 생물학적 방법으로 제거하기 위하여 함수율, 용도, 영양염류 등을 변화시키면서 생물학적 최적조건을 발견한 다음 황화수소 입구농도를 100, 200, 300ppm, 표면적 부하를 40, 60, 80㎥/㎡·hr로 변화시켜 결과 다음과 같은 결론을 얻었다. 낙엽 Compost에 의한 생물학적 탈취는 가능하였으며, 낙엽 Compost를 이용하여 황화수소 취기의 탈취를 위한 생물학적 최적온도를 온도 20~30℃, 함수율 62±3%이었다. 표면적부하 40㎥/㎡·hr, 충진층 높이 50㎝에서 황화수소의 농도별 제거율은 100ppm에서 99.9%이상, 200ppm에서 99.2%, 300ppm에서는 84%였으며, 농도 200ppm, 충진층높이 90㎝에서 표면적 부하를 40, 60, 80㎥/㎡·hr로 변화시켰을 때 제거율은 각각 99.9%이상, 99.9%, 85%이었다. The stydy was performed to remove hydrogen sulfide odor gas by the bio-filter. The optimum conditions of water contents, temp., and inorgarnic matters for this method was determined with a fixed concentration of hydrogen sulfide odor gas. Under this optimum conditions, the follwing results were obtained from various concentrations of hydrogen sulfide odor gas(100, 200, 300 ppm) and surface area load(40, 60, 80 ㎥/㎡·hr). Biological deodorization by leaf compost was feasible and its optimum condition of temperature and water contents was 20~30℃ and 62土3%, respectively. The rate of deordorization of hydrogen sulfide odor gag(100, 200, 300 ppm) with he height of packing material 50㎝ and surface area load 40 ㎥/㎡·hr was great than 99%, 99.2%, and 80%. Similarly, the rate of deordorization of 200ppm of hydrogen sulfide odor gas at surface area load(40, 60, 80 ㎥/㎡·hr) with 90㎝ of the height of packing material was great than 99%, 99% and 85% respectively.

金載洪,朴出在,金彰昊 동아대학교 공과대학 부설 한국자원개발연구소 1995 硏究報告 Vol.19 No.1
This study was carried out to interpret mathematically hydraulic behaviour in packing tower which packed 50 mm plastic Hiflow ring within d. 0.288 × H. 1.37 m. The results from experiment are as follows ; 1) In view of energy saving, the recent packing, 50 mm plastic Hiflow-ring was superior to conventional packings because of low pressure drop in high loads. 2) As relative error between mathematically caculated value and investigated value was less than 6% in the loading and flooding point, it found that their results were proved to adequancy. 3) Comparing calculated with experimented pressure drop in conditions of dry and wetted packing, relative errors are 3.96 and 5.6%, respectively. In order to evalute the operating character of packings, the type. size and material of packings must be estimated in various system and loads. This study is able to calculation, first all, the specific constants of each packing must be calculated. The mathematical interpretation method of this study revealed superior to existing methods because of low error in loading and flooding point.
