영문 초록

This study is to provide a basic data for the treatment of wastewater in small-decentralized sewage treatment of Kangwon-Do by measuring total removal efficiencies of organic compounds and nutrients. The experimental results showed that the removal efficiency of organic compounds was 80% when the volumetric loading has been below the 5 kg/day. The removal efficiencies were 92.3% of the initial BOD, 95.2% of SS by the Contact Oxidation Process Covered with Top-soil. By Capillary Perforation Trench Process, 88% of the initial COD was removed. Nutrient removal efficiency was so low to 30%. So the removal efficiency of nutrients was lower than that of organic matters. Effluent water quality of Enhanced-combined Septic Tank in August was 35 mg/l of BOD, 47.3 mg/l of SS. And T-N, T-P was similar to all processes on seasonal variation measurement. Effluent water quality in August was higher than the discharge quality standard. For the most of facilities, evasion of responsible management and lack of awareness by the residents to the facility were found.
