현재 구제역의 발생과 AI로 인한 손해를 모두 본 부담하고 있다. 또한 축산업에서 악취에 대한 민원은 끊임없이 제기되고 있으며 앞으로 더 발생할 것으로 판단되고 있다. 본 논문에서는 축사 및 계사, 돈사 등과 같은 밀폐형 시설물들의 실내 공기질을 개선하고 질병 등을 예방하여 농가의 소득을 증대 시키는 것에 목적을 두었다. 환기 유닛 자리에 설치할 저온 플라즈마 폐열 환기 장치를 개발하고 내부에 넣을 열 교환 소자 및 저온 플라즈마 램프, 밸러스트를 규격화 하여 강화된 공기청정 기능을 갖도록 하였다. 또한, ICT를 접목하여 기존의 기상 시스템, 유동팬, 기타 시설 장비들과의 연동이 가능하고 농가들로 하여금 실시간으로 모니터링이 되도록 새로운 통제 시스템을 개발하고자 한다.

To prevent surface and underground water pollution, wastewater treatment is essential. Four bench-scale activated sludge units (10 L operational volumes) were operated at 5, 10 and $20^{\circ}C$ for evaluation of treatment efficiencies with typical wastewater from swine housing. The units were set for a 24-hour cycle. As compared to the conventional process, high removal efficiencies for organic substances, nitrogen and phosphorus in swine wastewater were obtained simultaneously with an intermittent aeration process (lAP). The NOx-N produced during an aeration period was immediately reduced to nitrogen gas (e.g. $N_2$ or $N_2O$) in the subsequent non-aeration periods, and nitrification in aeration periods occurred smoothly. Under these conditions, phosphorus removal occurred with the release of phosphorus during the non-aeration periods followed by the excess uptake of phosphorus in the activated sludge during aeration periods. It was confirmed that the lAP had a better ability to remove pollutants under both low temperatures and high nitrogen loading conditions than the ordinary method did. In addition to that, the total emission of $N_2O$ from lAP was reduced to approximately 1/50 of the conventional process for the same loading. By adopting an adequate aeration programme for individual swine wastewater treatment, this system will provide a promising means for nitrogen and phosphorus control without pH control or addition of methanol.

The agricultural development of Korea has occurred at the expense of natural resources and environmental quality, and, today, one of the most urgent problem in the practices of intensive livestock farming is disposing of the animal wastewater. As a result, soil and water degradation and other environmental deterioration become apparent and they cause long-term loss in agricultural production. This paper attempted to summarize the environmental problems associated with agricultural activities, and to get some implications to minimize agricultural environment problems. It is proposed that sustainable agricultural is one of desirable directions for future Korean agriculture. The goal of the sustainable agricultural effort is to utilize the potential environmental quality problem. Agricultural operations may be more dependent upon the production practices and waste management techniques utilized by farmers than the size of the operation, the number of animal fed, or amount of waste involved. Also low-input farming technology can be suggested one of them, and disposing system of agricultural residues and animal waste should be developed with intensive concerns and financial supports.

This study was carried out to improve utilization of fly ash. Each animal waste was mixed with fly ash and composted This compost used at forage crops with corn, rye and alfalfa to examine to examine the fertilized efficiency and investigated productivity of forage crops, composition of this copmost and effect of fly ash on soil characteristics and composition. Content of organic matte, P2O5, K2O, CaO, MgO, Mn and B at the soil, which is given fly ash, increased. After the test crops were harvested, pH of the soil was maintained about 7 and contents of organic matter, phosphoric aicd, K, Mg, and B was increased at the soil of used fly ash. As fly ash was mixed, each DM yield of corn and rye was increased 10∼13% and 14∼21% especially alfalfa was increased 35% at the soil which is mixed fly ash with cage layer manure. As fly ash was mixed, each Crude protein (CP) of corn and rye was increased 6∼17% and about 29%, especially, as fly and cage layer manure was mixed CP of alfalfa was increased 33%. In conclusion, as fly ash is mixed with anlmal waste and use at forage crops, It makes the soil good and improve the productivity of forage crops.

The water quality in the rural areas is degrading due to a variety of causes such as the increase of the urban sewage and industrial wastes, the disposal of solid wastes, the growth of livestock waste, the growth of leisure facilities, the establishment of agricultural industry estates and etc. The water pollutants are scarce while the effluent is increasing from wide scattered sources. The technology specifically designed for the rural wastes water treatment plant needs to be implemented with improvement of agricultural water quality. 1. An integrated management measures against water pollution sources. The prevention of water pollution is the best measures in the environmental pollution. Hence, the most effective measures needs to be against the sources. Small-scale water treatment plants needs to be constructed in each village in the rural areas. As for the industrial effluent, the effluent discharge needs to be strictly monitored. Government subsidy for the establishment of treatment plant for livestock wastes is necessary. 2. The establishment of national-wide network for agricultural water quality. The network for agricultural water quality have been operated to conserve the agricultural water quality, and to develop management policies by the assessment of water pollution in the rural areas. The results of agricultural water quality network indicates that the water quality is degrading not only around urban areas but also in the distant rural areas, and the water quality at the pumping stations and weirs is worse than that of reservoirs. 3. The legal, systematic, and technical approaches for the agricultural water quality management. The actions currently implemented for the improvement of agricultural water quality involve temporary measures such as the improvement of irrigation facilities. These contingency measures are not effective in the long-term, and sometimes bring secondary pollution. Therefore, integrated measures covering the whole water environment such as the flow, quality, river morphology, aquatic ecosystem, and the surrounding environment, need be invented and implemented. Besides, the legal, systematic, and technical frameworks for the management are not fully established so far. The technology for the treatment of rural water pollution should be refined afterwards, and the research for the development of rural waste water treatment plant should be carried out.

전형적인 농촌지역 지하수의 질산성 질소 오염현상에 대하여 오염원 규명, 지하수 오염범위와 오염도 파악을 위하여 이 연구를 수행하였다. 연구지역은 대규모 축사가 곳곳에 위치한 축산단지 인근지역이며, 벼농사와 포도재배가 이루어지고 있다. 이 지역의 수리화학적 특성을 밝히기 위하여 지하수파 지표수 시료를 채취하여 화학분석을 수행한 결과, 1차 17지점, 2차 22지점에서 채취한 지하수 시료 중 32~42%에서 질산성 질소 성분이 음용수질 기준(10 mg/L)을 ,초과하였으며, 77%에 해당하는 지점이 인위적 오염물질의 유입가능성이 있는 것(3 mg/L 초과)으로 나타났다. 질소 동위원소($\delta$$^{15}$ N-NO$_3$) 분석 결과에 의하면, 질산성 질소 성분은 대부분 축산폐수 기원임이 밝혀졌다. 현재 축사가 운영되고 있는 지역 뿐 만이 아니라 폐축사가 위치한 지역에서도 질산성 질소 오염이 나타나 축사가 천부지하수질에 오랜 기간동안 영향을 미칠 수 있음이 밝혀졌다.

The unit loading factor total nitrogen(T-N) for domestic waste water was 7.582g/capita, day, and that of the gray and toilet waste water among the domestic waste water were 1.826g/ capita, day(24.1%) and 5.756g/capita, day(75.9%), respectively. The other hand, the unit loading factors of total phosphorus(T-P) for domestic waste water was 0.925g/capita, day, and that of gray and toilet waste water among the domestic waste water were 0.470g/capita, day(50.8%) and 0.455g/capita, day(49.2%), respectively. 3. In offering Price per million won, the T-P loading factor for drinking manufacture, confectionery manufacture, beer-manufacture and fibre manufacture in the industrial pollutant sources estimate to be 0.350g/day, 0.099g/day, 32.351g/day and 1.536g/day, while T-N loading factor about them in the industrial pollutant sources estimate to be 4.117g/day, 2.414g/day, 106.726g/day and 60.504g/day, respectively. 4. The T-P loading factor according to wash-water of milch cow and pig were 6.735g/day and 18.526g/day, in case of T-N they were 42.397g/day and 27.226g/day, respectively. 5. The T-P loading factor for pollutants drainage in the Paddy fields, fields and forests area were 0.082g/are, day, 0.014g/are, day and 0.002g/are, day, and the T-N loading factor were 0.309g/are, day, 0.158g/are, day and 0.064g/are, day, respectively. The diffrent of the loading factor for pollutants discharges in the agricultural area were resulted from the rainful intensity, the rainful, the amount of fertilization manure, and etc.
