Study In Comprehensive Utilization Of Municipal Sewage Sludge In The Process Of Sintering Brick

Rapid urbanization in China has resulted in a drastic increase of waster sludge. In highlyurbanized cities, sludge disposal by land filling may no longer be appropriate owing to land scarcity and increasingly stringent environmental control regulations. Therefore future trends in sludge management are towards minimization and reutilization as useful resources. Incineration is one feasible means of converting bulky sludge to practically inert, odorless and sterile ash. The disposal of this significantly reduced volume of sludge ash can be subsequently handled easily with much smaller scale. The disposal problems will be drastically reduced if sludge can be put to large-scale economic applications. Utilization of municipal sewage sludge (MSS) in the process of manufacture sludge-shale brick can get the same effect as incineration.This paper reviews current studies in reutilizing sludge as brick. t studies in reutilizing sludge as brick. derived from sludge, the processing technology, and the heat isolation of the materials for construction purposes have been discussed.The results showed that a great deal of municipal sewage sludge can be consumed in the process of manufacture sludge-shale brick. It did not affect the qualities of the shale brick by adding some dry municipal sewage sludge into the brick, it also improved the capability of heatproof.
