The objective of this study is to find solid waste decomposition characteristics in landfill without leachate discharge. This study was observed variation of landfill gas production rate and leachate for stabilization assessment, and using four sets of lysimeter as experimental apparatus. Solid waste decomposition was accelerated in without leachate discharge system by sufficient moisture for methane bacteria. And gas production rate was between 54.2ℓ/kg VS ~335.9ℓ/kg VS in each lysimeter. Generation time of methane gas was showed different in each lysimeter, but it was much faster than literature research. The time of stabilization phase were began as follows : L-1 400 day, L-2 350 day, L-3 170 day and L-4 day respectively. Decreasing times of BOD/COD ratio and C/N ratio were necessary more than literature research because organic matter was not discharge such as wash out.

One of the economic and efficient process to treat the leachate which venerates at the landfill is the combined treatment with the sewage, which can result in the over-loading and the side effect at the treatment of wastewater. Therefore, this study aims to compare with the generalized A/S process and BNR one in consideration of the nutrient, which apply the combination treatment, and to derive the proper mixing rate of A/S process and BNR one.

This study was performed to evaluate the odor control of sewage by oak pyroligneous liquid. And, odor control experimental was compared NaOH solution(20%) to pyroligneous liquid. The results were summarized as follows ; Results of pyroligneous liquid analysis showed pH was very low, and heavy metals were most of not detected. pyroligneous liquid was showed more effective for odor control than NaOH solution(20%). NaOH solution(20%) and sewage was producted NH3 gas through chemical reaction. Suitable dilution rate of pyroligneous liquid was showed thousand times, but it was thought problems in economic. Therefore, the pyroligneous liquid would be effectively in odor control with use follow conditions ; garbage waste box, landfill waste layer and moving dressing room in tourist facilities etc.

The objective of this study is to solve the problems related to the effluent quality in RBC process: media clogging and the biomass sloughing. Three stage RBC with Autoxidation phase was operated along with the existing three stage RBC operation by varying the operational parameters in order to compare removal efficiencies of organics and nitrogen. The BOD removal efficiencies in the three stage RBC with Autoxidation phase were over 95% at a organic loading of 98.4g BOD/㎡/day The existing three stage RBC Process showed a 95% removal at a organic loading of 49.2g BOD/㎡/day, Suspended solids removal efficiency was between 61 and 70 percent in the Autoxidation Phase at 1st stage RBC by biomass sloughing, and that of the existing RBC was between 45 and 61 percent. Removal of ammonia-nitrogen determined by varying NH_(3)-N loading rate showed a 85.3~92.1 percent in the Autoxidation phase and a 67~76percent for the existing three stage RBC process. NO_(3)-N level in the effluent increased with decreasing influent loading. In the determination of the kinematic coefficient, area capacity constant(P) in the first stage Autoxidation phase of RBC was 39.9gBOD/㎡·day and half velocity constant(Ks) was 306mg/L. In the existing three stage RBC, they were 46.6gBOD/㎡·day and 467mg/L. respectively.

This investigation was carried out to study generation of solid waste and collection system in the College of Engineering and College of Social Science, library, dormitory and student center of Kangwon National University. It is to supply basic data for solid waste management. Each result of investigation considers effect getting generation property, unit waste generation rate and reusing.

This investigation was carried out ot study on the generation property, management and separate collection rate of solid waste in the Gu-Gok Falls. Generation rate of solid waste was 80.785kg/day and unit waste generation rates was 65.55g/dayㆍtourist one person. Physical component of solid waste were garbage 46%, papers 20%, empty bottles 10%, respectively. A plan is required to decrease generation rate of garbage waste, As result to investigate separated garbage can, papers and can were separated more than 60%. But empty bottles and scrap iron were separated less than 50%. P.E.T, steel can, aluminum can and empty bottles were 20% of total generation rate, and profit of reuse is ₩700,800/year.
