Sludge or sludge (hereinafter referred to as 'sludge') is generated during the treatment of sedimentation tanks and various sewage and wastewater. At this time, the generated sludge is treated according to a separate method after the dehydration process. However, since the sludge generated during the treatment of various wastewater and wastewater contains 95% ~ 98.8% (source: Naver Knowledge Encyclopedia), a large amount of water is used. After concentrating the sludge above a certain concentration, the dehydration process is performed. However, even though the sludge undergoes a dehydration process, the sludge has a large amount of water content, and a large amount of sludge agglomerates to exist as a lumped dehydrated cake. The dehydrated cake is to mix the solidifying agent (quick lime, cement, etc.) that can solidify the liquid material, and then to bury the dehydrated cake solidified through the curing process. Here, curing refers to a phenomenon in which cement contained in concrete encounters water and gradually hardens.
