춘천시 생활쓰레기의 위생관리를 위한 배출 및 이·화학적 특성

Generation and physico-chemical characteristics of municipal solid wastes are very important for sanitary management. However, that has not been investigated so far especially in chunchon. And so, we tried to examine many things in detail. It was resulted that density was $90{\sim}94kg/m^3$ in school and office zone and $290{\sim}298kg/m^3$ in apartment and market place. The compositional weight fraction was food, 40~54%, paper, 14~18%, vinyl and prastic, 14~20% in house zone and market place and paper, 42~70% in school and office zone. Moisture was estimated to be 54~57% in independent house zone, apartment and market place and 11~23% in school and office zone. And three composition was water content, 44.1%, incineration particle, 11.2%, volatile parts, 44.7% in respectively. That is because of seasonal effects and regional chracteristics. In the results of chemical composition and caloric value analysis, carbon(C) was 80% in vinyl and plastic and oxygen(O) was 54.4% in paper.

This research aims to improve the previous trench process. The modified process is consist of 3 processes; first settling tank, 3-staged second contact-filter, and last trench system. The experiments was operated by varying the HRT 8, 6 and 4 hours in trench. The results of laboratory experiments showed removal rate of 97∼99% of TBOD, 92∼98% of TKN, 91∼98% of T-P. From the results of this research, organic materials were removed in settling tank and nutrients in the trench stage. Therefore, it is recommended to replace the previous 3-staged contact-filter to 1-staged one, and to increase contact-time in trench system.
