여러 환경정화 방법들 중 광촉매를 이용한 처리기술들이 관심을 모으고 있다. 광에 의해 활성을 갖는 여러 촉매들 가운데 이산화티타늄($TiO_2$)을 중심으로 한 연구가 가장 활발히 진행되고 있다. 본 연구는 TiO2를 개질화하여 광활성이 우수한 광촉매를 개발하고 이를 이용한 VOC 처리를 목적으로 하고 있다. VOC 중 할로겐화(halogenated)된 것들의 처리는 매우 어려우며 현재의 소각방식으로는 효과적으로 처리되고 있지 않다.

This study is the study desiring to solve the problem by utilizing the kinds of recycled resources considered to be troubled complementarily. Namely the reaction of potential hydraulicity of Blast Furnace Slag Powder (BS) shall be reacted with the alkali of Recycled Fine Aggregates Coarse Aggregate, it has been experimented to obtain the optimum value with the replacement ratio of incineration plant ash (WA) treated with the slaked lime as the experiment variable by solving the alkali of shortage with the Ordinary Portland Cement (OPC). As a result, the liquidity and the air volume are declined slightly as the replacement ratio of incineration plant ash WA increases, the mixture of incineration plant ash WA 1% has been analyzed to be the most suitable considering the viewpoint of effective handling of waste as the compression and the tensile strength showed the maximum value before and after 1% even though it was disadvantageous with the increase of chloride content.

The purpose of this study is to suggest the design parameters, which are applied to the solid waste treatment and management systems in rural area. In order to drive out the parameters, the solid waste production and management systems in rural and urban areas had been surveyed and analyzed, respectively. The comparisons of the analyzed results are also introduced in the paper. The rural areas referred to the survey are grouped in accordance with the industrial activities in those areas. The conclusions of the study are as follows: 1) The solid waste volumes produced per day per capita in rural area are less than those of urban area. For example, the average volume produced in rural area in 1995 is 0.85kg, which is two thirds of those in Seoul area. 2) for the treatment, the country has depended mainly on landfill. On the other hand, the incineration treatment ratio has been in creasing in rural area. 3) The physical and chemical properties of the rural solid waste, according to the analysis, are similar to those of the urban areas, which means the living pattern in those two areas have a little difference.

A questionare survey was performed to investigate the citizen's attitude concerning waste treatment facilities. Most people recognized the seriousness of the waste treatment problem and think that more composting facilities should be built. People dislike most the landfill facility, followed by the nightsoil treatment facility, the incineration facility and the composting facility. Most people answered that the disirable distance from their house to the treatment facility should be farther than 4km for the landfill facility, farther than 2km for incineration and composting facilities and farther than 1km 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.

폐기물처리에 있어 기존 스토카 방식으로는 다이옥신 문제에 대한 근본적 해결과 발생된 소각잔재물의 처리가 곤란하다. 아울러 비산재 적정처리에 따른 운영비 부담이 증가와 매립시 잔재물중에 함유된 다이옥신등 유해물질의 미처리에 따른 매립지의 2차 오염을 유발시키고 있다. 인터넷등의 보급 확대에 따른 선진국의 환경규제내용을 실시간으로 확인할 수 있고 생활수준의 향상에 따른 Clean 환경에 대한 욕구가 증대되고있으며 환경호르몬 등의 유해물질에 대한 주민 피해의식 및 환경에 대한 주민의 요구 수준이 증대되고 있는 실정이다. (중략)

컴퓨터는 그동안 환경에 거의 영향을 미치지 않는 청정분야로 인식되어 왔다. 그러나 오늘날에는 제조단계에서는 물론이요, 수명이 다한 폐PC의 발생량이 빠른 속도로 증가함에 따라 이들을 매립이나 소각하여 처리할 경우에 수계, 토양, 그리고 대기에 미치는 영향이 매우 큰 것으로 알려지고 있다. 이러한 상황에 대처하기 위해서는 폐PC의 발생량을 추산할 필요성이 있으며, 추산된 발생량에 대한 처리방안을 마련하는 것이 요구된다. 따라서 본 논문에서는 우리 나라의 1999년말까지의 폐PC 발생량을 추산하고, 페PC의 처리방안을 탐색하고자 한다.

최근 인구증가와 더불어 도시화, 산업화 및 생활수준의 향상으로 인해 가정 및 사업장 등에서 배출되는 음식물쓰레기의 발생량이 급속하게 증가함으로써 쓰레기처리에 따른 비용절감과 효율적인 폐기물 처리방법들이 중요시되어지고 있다. 현재 우리 나라에서 쓰레기처리법으로 가장 많이 활용되고 있는 기술은 매립이다. 그러나 매립처리는 유기물이나 유해물질의 유출 및 악취발생 등 매립장 인근에 환경을 오염시키고 있다. (중략)

Radiological safety for the conventional operation of Demonstration-Scale Incineration Plant (DSIP) was assessed on the basis of the results of trial burns using the simulated and real radioactive wastes. Radiation dose assessments for routine releases on an annual basis as well a several severe accidental releases on a short-term basis (2h) revealed that there would be no significant environmental impact when low-level waste Is incinerated in DSIP. For semivolatile radioactive cesium species, expected emission concentrations slightly exceeded 10% of maximum permissible concentration. Removal characteristics of the bag filter for condensed-phase cesium species was investigated by the trial burns of simulated waste with inactive cesium tracer. In the off-gas before passing through bag filter, distributions of condensed cesium species in the transition size ranging between the diffusional and inertial region are less than 5%. The overall collection efficiency of the bag filter for cesium species was higher than 99.9%, showing enough decontamination capability as a primary filter for the low-temperature dry off-gas system in radwaste incineration plant.

Waste explosives such as useless ammunition discharged from the military and coproduced useless explosives during the manufacturers production process have been continuously produced. These are difficult to dispose with normal waste treatment facilities due to the dangers of fire and explosion. An open burning or an open detonation at military designated disposal facilities is a classical treatment method for the dangerous explosives. The classical method raises various environmental problems by the emission of hazardous materials. An air pollution by the emission of hazardous gases such as SO_x and NO_x, soil and water contaminations by the accumulation of non-biodegradable heavy metals, are representative pollution examples. To overcome these problems, various processes for eco-friendly waste treatment methods have been developed, and some processes have already been operated in some countries. In the current report, various eco-friendly disposal processes for waste explosives or harmful materials, and their advantages and disadvantages are documented to suggest future development directions for reducing the hazardous substances by the treatment processes.
