<p>A municipal solid waste treatment device, according to the present invention, comprises: a crushing unit which tears municipal solid waste and selectively pulverizes organic matter; a selection unit for classifying and selecting the municipal solid waste discharged from the crushing unit; a reaction unit for bio-drying the classified and selected municipal solid waste; a return unit which returns the bio-dried municipal solid waste to the crushing unit so as to increase a selectivity rate; and a recycling unit for recycling the remaining organic matter and combustibles, wherein the crushing unit is a rotary drum-type crusher for naturally and selectively pulverizing only the organic matter without using force, thereby enabling high-purity selection with minimum energy consumption, and the crushing unit adjusts a moisture content by using the organic matter dried in the reaction unit at the rear end part whereby a higher selection efficiency can be obtained, and the reaction unit at the rear end part is a bio-drying device for carrying out a drying process in a short time without using external drying energy.</p> |
