淨化槽 슬럿지의 堆肥化에 관한 硏究 = A Study on the Composting of Septic Tank Sludge

다국어 초록 (Multilingual Abstract)

This study was performed for composting of septic tank sludge which had been not dewatered in the various bulking aegents and investigating the condition and the adequate composting and the mixing rate. And results of the research are as follows;
(1) Rice straw in the five bulking agents was the most fermentavility and the mixed rate was 1:3 in the time
(2) The range of the optimum moisture content was 64.2-67.3% and air quantity was 0.8ℓ/min-㎏VS in the time
(3) The coming to the time of the maximum temperature was showed between 58 and 110 hrs after inputing composter.
(4) It being composting by the windows method, If the Quanlity was over 1 ㎥, the composting was successful.
(5) The composting was the most quick, optimum under C/N ratio of 29.92-34.66
(6) The maximum temperature of 49-53℃ was showed under the adequate condition of each element;Moisture Content, Air Quautity, pH, CO₂ prodution quantity was 0.59-0.69m mole/day.g(VM) in the time
