환경기초시설에 대한 시민의 의식을 알아보기 위하여 설문조사를 실시하였다. 대부분의 시민이 쓰레기 처리문제의 심각성을 인식하고 있었으며 퇴비화시설을 가장 많이 지어야 한다고 느끼고 있었다. 시민들이 가장 싫어하는 시설은 매립장이었고 분뇨처리장, 소각장, 퇴비화시설의 순이었다. 집과의 허용이격거리는 매립장은 4km 이상 소각장과 퇴비화시설은 2km 이상 하수처리장은 1km 이상 떨어져야 한다고 응답한 사람들이 많았다. 지역주민이 원하는 보상정도는 이사비용 + 토지가 + 불편감수비용 (토지 및 건물가격과 비퉁한 금액) 을 원하는 사람이 가장 많았다. 처리시설에 대한 수용도에 있어서는 완벽한 처리시설이라도 30% 정도의 응답자가 허용을 하지 않겠다고 응답하였다. A questionare survey was performed to investígate the citizen's attitude concerning waste treatment facílíties. Most people recognized the seriousness of the waste treatment problem and think that more composting facilities should be built. People dislíke most the landfill facility, followed by the nightsoíl treatment facílity, the íncíneration facílíty and the compostíng facility. Most people answered that the disirable distance from their house to the treatment facílity should be farther than 4km for the landfill facílity, farther than 2km for incineration and composting facílities and farther than lkm for the wastewater treatment plant. Most people want moving cost + land price+inconvience suffering cost (amount equal to the land prize+building prize) for their retrieval. About 30% of people answered that they will not accept any waste treatment facility even though it is perfect.

서울시민을 대상으로 퇴비화 및 퇴비에 대한 일반시민의 의식조사를 실시하였다. 대부분의 시민들이 음식물쓰레기의 처리문제를 심각한것으로 인식하고 있었으며 웅답자의 91. 9%가 음식물쓰레기로 퇴비를 만들수 있다는 사실을 알고 있었다. 또한 화학비료보다 음식물쓰레기로 만든 퇴비를 선호하고 있었으며 가축분뇨로 만든 퇴비보다 음식물쓰레기로 만든 퇴비의 품질을 더 좋게 생각하고 있었다. 그리고 화학비료를 주고 재배한 채소보다 퇴비를 주고 재배한 채소를 좋게 생각하고 있었으며 10-20%정도의 비싼가격을 감수할 의사가 있었다. 또한 대다수의 사람들이 퇴비화를 위한 분리배출에 대해 협조할 의사를가지고 있었으며 음식물쓰레기는 소각이나 매립보다 퇴비화로 처리해야 한다고 생각하고 있었다. A questionare survey was performed to investigate the citizen's attitude toward garbage composting and compost. Most people considered that the food waste treatment problem is serious and 91. 1% of people know that it is possible to make compost out of food waste. Also, people think that compost made from food waste is better than the compost made from manures. People favor vegetables grown by organic compost than those grown by chemical fertilizer and was willing to pay 10-20% more prize. Most people was willing to cooperate in source separation for garbage composting and throught that the most desirable treatment method for garbage would be composting.

Since the amount of solid waste from construction depends mainly on its type and scale as regional development condition, the estimation of the total amount of the construction waste is actually difficult. The approximate computation of the total amount of the construction waste is able to be estimated by determining the amount of the construction waste per unit area(the unit construction waste). However, in Korea, the unit construction waste has not been set up yet. In this study, the unit construction waste, which is classified into the case of construction and the case of demolition, is established on the bases of the existing various kinds of actual data and the investigation data.

수리학적 체류시간에 따른 폐활성슬러지의 혐기성 소화 특성

김성순,김갑진,탁성제,김운공 중앙대학교 기술과학연구소 1997 기술과학연구소 논문집 Vol.27 No.-

본 연구는 혐기성 소화 특성을 알아보기 위하여 2차 슬러지를 대상으로 수리학적 체류시간 (Hydraulic Retention Time, HRT)에 따른 유기물 제거효과, 가스발생량 및 탈수특성등을 위한 증온 혐기성 소화실험을 수행하였다. 유기물 제거효율은 HRT에 비례하여 계속 증가하는 경향을 나타내었다. 가스 및 메탄가스 발생량은 HRT가 15이로 증가할 때 까지는 계속 증가하다가 20일에서 오히려 감소하는 경향을 나타내었는데, 이는 유기물의 제거율이 다소 둔화되면서 가스로 전환되지 않고 소화조내에 그대로 축적되었기 때문이라고 판단된다. 한편 슬러지 탈수성은 HRT 증가에 따라 양호해졌다. 상기의 결과로 2차 슬러지의 혐기성 소화시 HRT는 15일에서 유입 VS부하율이 1.09kg VS/㎥/d일 때 가장 좋은 소화 효율을 나타냄을 알 수 있었다. The objectives of this study are to investigate the effect of organic removal and the dewaterability of sludge with Hydraulic Retention Time(HRT) using secondary sludge and estimate anaerobic digestion kinetic coefficient of microorganism. As the results of tests, the efficiency of organic removal increased gradually as the HRT was increased. And gas and methane gas production was increased until HRT got to 15 days. However, at HRT 20days it was significantly lower than HRT 15days. It means that a portion of removal organic matters were accumulated in digester without gasification. In the results of value of specific resistance, dewaterability of sludge was increased proportionally as HRT increased. From the above results, on mesophilic anaerobic digestion of waste acivated sludge, the optimum digestion efficiency was found at HRT 15days with VS loading rate of 1.09 kgVS/㎥/d.

The general objectives of this study are to develop a new biofilm reactor equipped with agitating mixer and to evaluated the treatment efficiency of the reactor. The experimental tests were conducted to estimate the oxygen transfer rate of agitating mixer system. Results are as follows. ⅰ. The oxygen transfer coefficient, KLa, was 8.94hr1 and 7.50 hr1 at 500rpm and 250rpm of agitating mixer speed, respectively. When the agitating mixer was used in the biofilm reactor, 22.5% and 18.8% of oxygen transfer rates were increased at 500rpm and 250rpm, respectively. ⅱ. The removal rate of BOD and CODcr was decreased by 5.0% when the agitating mixer speed was varied from low (250rpm) to high level (500rpm). ⅲ. The concentration of attached biomass had a difference of 5.0% to 7.3%, whereas that of suspended biomass had a difference of about 15.0%, depending upon varia-tion of the agitating mixer speed.

Recently, our circumstances are threatened by an accident that leakage of underground storage tank and illegal dumping of synthetic organic compounds at chemical plants and many treatment methods, Activated carbon adsorption, Ozonization, Membrane filtration and Photocatalystic oxidation, are developed to remove such a synthetic organic compounds. And it has reported that Activated carbon adsorption have a great removal efficiency to nondegradable matters and organic compounds which have a high molecular weight. Comparing with other adsorbents, Activated carbon adsorption have a worse efficiency when adㆍdesorption speed is low. Thus improved type of adsorbents was invented and one of those is Activated Carbon Filter. The purpose of this study was getting information about adsorption characteristic of phenol which can be applied Activated Carbon Fiber and Granular Activated Carbon. In detail, With comparing removal characteristics of phenol in the presence Humic Acid using Activated Carbon Fiber(ACF) and Granular Activated Carbon(GAC), it is to certify an effective application of Activated Carbon Fiber. At the range of this study, Batch test, Isotherm adsorption test and Factorial analysis, following conclusion were obtained from the results of this study. Batch test was carried to know time of adsorption equilibrum. In this study about time of adsorption equilibrium by ACF was faster than GVC's, for developed micropore of ACF. From the result of phenol adsorption test, High removal rate of adsorption is shown at pH 5. The result of Isotherm adsorption test, it has represented that the Freundlich's isotherm is most suitable one in others, that a ACF's adsorption capacity is more excellent than GAC's. Adsorption of phenol exiting humic acid is decreased getting raised humic acid concentration. Since ACF's micropore is developed at this time, an effect of high molecular humic acid is lower. Factorial analysis was carried to know about Main effect which was injection dosage of adsorbent in the range of this study.
