高濃度 有棄性 廢棄物의 營養鹽類 除去工程에 關한 硏究 : 糞尿를 中心으로 = A Study on the Nutrients Removal Process for Organic Waste in High Concentration

다국어 초록 (Multilingual Abstract)

A2/O process was adapted to investigate the feasibility of nutrient removal, i.e, nitrogen and phosphorus from nightsoil and to obtain the optimum operation parameters for nightsoil treatement in laboratory.
The results of this study were as follows.
1) A2/O process could be applied to nutrient control from nightsoil.
2) The removal efficiencies of substrates and nutrients were increased as internal recycle rate was increased. The optimum rate of internal recycle was 300%.
3) The removal efficiencies of substrates and nutrients were decreased as organic loading was increased. The optimum F/M ratio was 0.2 ~ 0.3kg·BOD5/kg·MLVSS·d.
4) In the optimum conditions, which were 300% of internal recycle, 100% of sludge recycle rate and 0.2 - 0.3kg·BOD5/kg·MLVSS·d of F/H ratio the removal efficiencies of TBOD, TCOD, SS, T-N, and T-P were 98.6%, 93.8%, 98.3%, 83.4%, and 53.6%, respectively.
