Method of Preparing Artificial Lightweight Aggregate by Recycling Anaerobic Digested Organic Sludge
The present invention relates to a manufacturing method of artificial lightweight aggregate for recycling a large amount of anaerobic digestion organic sludge. The present invention relates to the manufacturing method of artificial lightweight aggregate which wet-mixes anaerobic digestion organic sludge, clay minerals, and anaerobic digestion dehydration sludge to adjust a moisture content to 50% by weight or less, molds, dries and fires it to recycle anaerobic digestion sewage sludge, which has a low content of organic matter to limit its recycling as a fuel, and fires lightweight aggregate by inner heating to increase heat efficiency and lower a firing temperature.
본 발명은 혐기소화 유기성 슬러지를 대량으로 재활용하는 인공경량골재 제조방법에 관한 것으로, 혐기소화 유기성 슬러지, 점토광물 및 혐기소화 탈수슬러지를 습식 혼합하여 수분함량을 50중량% 이하로 조절하고, 이를 성형, 건조 및 소성시켜, 유기물 함량이 낮아 연료로의 재활용이 제한되는 혐기소화 하수슬러지를 재활용하고, 내부의 발열로 경량골재를 소결시켜 열효율을 높이고, 소성온도를 낮춘 인공경량골재의 제조방법에 관한 것이다.
