Abstract

A mathematical model was developed for static composting process of municipal solid waste (MSW) based on the thermodynamics, kinetics of microbial growth, and hydrodynamics. A pilot scale aerobic ferment device was designed without leachate and malodor discharging. Its reasonable size, leachate collecting and recycling system, air distributing, and malodor recycling system were determined by the model and local conditions. The device was of great significance to study the theory, optimize composting parameters, and to instruct the designing of full scale device in the future.
