A questionary survey was conducted to investigate citizen's attitude to treatment facilities of municipal solid waste in Miryang during 8. June of 1998 and 22 June of 1988. Collection effiencies was 86.7%, as 260 individuals of the 300 individuals. The survey showed that 43.0% of answers recognized seriousness of problem of the waste treatment and 33.1% of respondents concerned about recycle of organic waste. 40.8% of total answers said that they most hated landfill site among waste treatment facilities, and most citizens wanted as much distant as possible from waste treatment facilities. It was investigated that the greater part of respondents wanted the greatest compensation. About 58% of respondents was opposed to complete waste treatment facilities. 36.2$ among answers wanted establishment of waste treatment facilities in an industrial complex or an industrial area. The majority of respondents was willing to increase recycle rate and recognized seriousness of landfill site security. The majority of citizens do not trust environmental administration of Miryang City and they think that democracy and open of administration need for overcome MINBY.

침출수의 수량 및 수질변화를 평가하기 위하여 세 종류(소각재 100%, 소각재 70%+일반생활폐기물 30%, 생활폐기물 100%)의 모형매립조를 실제 기상조건하에서 운영하였다. 실험결과, 누적 침출수 발생률이 모형매립조 A와 B가 모형매립조 C보다 높은 것으로 나타났다. 모형매립조 A는 pH가 pH 9~11의 범위였으나 시간이 경과하면서 중성으로 점차 변하였다. 염소이온은 소각재를 매립한 모형매립조 A와 B가 높은 것으로 나타났으나 모형매립조 C의 경우 낮게 나타났다. 생활폐기물을 충전한 모형매립조 C의 경우 침출수내의 유기물 농도가 다른 모형매립조보다 높게 나타났다.

열악한 지반물성을 갖는 쓰레기 매립지반를 건설부지로서 사용하고자 할 경우 상당한 침하가 유발될 수 있다. 이 경우 쓰레기 매립지반을 건설부지로 활용하고자 검토하는 지반공학자들에게는 열악한 압축 물성에 대한 파악 및 이에 대한 대책 방안이 마련되어야만 안전하고 경제적인 시공이 이루어질 수 있다. 따라서 본 논문에서는 대부분 매립 처분되고 있는 플라이애쉬를 도시 쓰레기와 함께 혼합매립함으로써 열악한 도시 쓰레기의 압축특성을 개량하여 침하를 억제할 수 있는지에 대하여 검토하였다. 이를 위해 플라이애쉬가 혼합된 도시 쓰레기에 대하여 대형압축실험과 모형매립조실험을 수행하여 압축특성에 대한 안정화 정도를 평가하고자 하였다. 실험결과, 플라이애쉬의 혼합비율이 증가함에 따라 압축성이 상당히 억제되었으나, 배수능력은 감소할 수 있으므로 실제 적용시에 이러한 특성들이 함께 고려될 필요성이 있다.

In this study, we investigated the concentrations of volatile organic compounds (VOC) in the ambient air of a small scale municipal waste landfill site. Seasonal sampling was carried out simultaneously at two sites, i.e. one in the center of the landfill area, and the other at a boundary site. Among 38 target VOC, toluene appeared to be the most dominant compound, followed by benzene. and xylenes. The higher levels of BTX imply that paint -containing materials and/or organic solvents are the most significant sources of the VOC in the landfill environment. Seasonal variations for the samples collected at the landfill site indicated that the VOC concentrations tend to be higher in the spring and fall season and lower in the winter season. In addition, night- time concentrations appeared to be generally higher than day-time. Such daily variation might be due to more stabilized atmosphere during the night-time. Similar patterns were also found in samples collected at a boundary site. This study demonstrated that the municipal landfill, although it is small -scaled, could be an important emission source of atmospheric VOC, particularly in the vicinities of the landfill. Thus, an appropriate control strategy is required to prevent any undesirable secondary pollutions from the environmental sanitary facilities such as landfill.

석대동 매립장은 부산광역시에서 1987년부터 93년까지 발생한 생활폐기물을 매립한 곳으로 산간매립에 속한다. 매립장 표면의 토양특성과 식생 분포를 근거로 12구역으로 나누고 디스크-장력 침투계 (Disc Tension Infiltrometer)로 불포화대 수리 특성을 추정하였다. 추정된 매립장 상부의 복토된 토양은 2.2$\times$$10^{-4}$~8.1$\times$$10^{-3}$ cm/sec 범위의 포화수리전도도를 갖는다. 이 값을 근거로 순침투율을 추론하면 939 ㎥/day이다. 주변에서 유입되는 지하수가 없거나 폐기물에서 수분 발생이 없다고 가정할 때 순침투율을 근거로 일침출수 발생율을 추정할 수 있다. 유사적 수문현상에 관한 모델들을 이용하여 침출수 수위상승과 산간매립장 옆 사면과 매립장 하부를 통한 침출수 누출율을 분석하였다.

The purpose of this paper is to study on the investigation of abandoned waste landfill for rehabilitation. The geotechnical and environmental field and laboratory tests for wastes dumped at municipal site were carried out. Testing wastes were sampled at the illegal landfill site The various samples such as waste. soil, groundwater, gas, leachate were taken in the landfill site. As a result of this study, the engineering properties and concentration of samples were investigated The result of this study was used for introduction the rehabilitation method and treatment of unregulated closed landfill.

As the size of our industry and population inclose, the byproducts such as municipal solid wastes, industrial wastes are in the increasing phase. The treatment of such things is rising as a social problem. Today, the final disposal of these wastes depends mostly on the landfill, and the sanitary landfill is required and designed for preventing soil and groundwater contamination. Clays have been used for a liner material of a sanitary landfill, however, the high quality clay is hard to come by and quite expensive as a lining material in our country. Using the waste lime produced abundantly every year from chemical processes was studied here, made from the proper mixing of the bentonite and the waste lime meets the regulations from the USEPA. The soil property index tests (sieve analysis, specific gravity test Atterberg limit test) were performed, and at last to confirm the sorption characteristics of the bentonite and the waste lime the sorption isotherm equilibrium test and the sorption isotherm were performed with Toluene and Ethylbenzene which are the main components of the leachate from the landfill.

A bench-scale continuous activated sludge system was operated in order to study the effects of solid waste landfill leachate on municipal wastewater treatment. The leachate sample was collected from Nanjido landfill. During the 7 weeks of operational period, the leachate content in the influent fed to the system was increased stepwise from 3% to 5% and 7%. The solids retention time was the major process control parameter, and it was 10 days. With the municipal wastewater alone, COD removal was 75%. The removal percents, however, decreased to 60% and 45% when the leachate content was 3% and 7%, respectively. For the wastewater spiked with the leachate, the sludge production was higher than for the municipal wastewater alone. Sludge settleability determined by SVI deteriorated with the increase of leachate content. The specific oxygen uptake rate, however, was measured higher as leachate content increased.

In the past, MSW (Municipal Solid Waste) disposal was typically done by recycling, incineration, or landfilling. In South Korea prior to the late 1950's, land burial was usually accomplished by disposal in an open dump. Currently, with increasing concerns and environmental recognition, MSW disposal and landfilling is more restricted. MSW landfill facilities have been developed with certain design and construction specifications. However, these methods have a space for improvement. MSW landfill facilities follow a step wise approach of design, construction, operation and closure management after use in agreement with established environmental and sanitary standards. This study intends to give a technical guidance for installation and consideration of newly established MSW landfill facilities, and also provide an establishment and regular inspection of MSW landfill facilities.

The ultimate target of restoring waste landfills is revegetation. The most effective method for increasing species richness and biomass in nutrient limited waste landfills is the use of fertilizers. The aim of the present study was to investigate the effects of nitrogen fertilizer, and the addition of carbon through sawdust, sucrose and litter, on vegetation dynamics at a representative municipal waste landfill in South Korea: Kyongseodong. A total of 288 permanent plots $(0.25m^2)$ were established and treated with nitrogen fertilizer (5, 10 and $20Ng/m^2$), sawdust $(289g/m^2)$ sucrose $(222g/m^2)$ and litter $(222g/m^2)$. The aboveground biomass was significantly enhanced by nitrogen fertilizer at 5 and $10Ng/m^2$, compared with the control plots. The total cover of all plant species increased significantly on plots treated with 5 and $20Ng/m^2$, as well as on those treated with sawdust and sucrose, compared with the control plots. The higher species richness after nitrogen fertilization of 10 to $20Ng/m^2$, and the sawdust and sucrose treatment demonstrated that this was an appropriate restoration option for nutrient deficient waste landfills. This study demonstrated positive nutrient impacts on plant biomass and species richness, despite the fact that municipal waste landfills are ecosystems that are highly disturbed by anthropogenic and internal factors (landfill gas and leachate). Adequate N and C combined treatments will accelerate species succession (higher species richness and perennial increase) for restoration of waste landfills.
