Ventilation Measurement and Simulation Optimization for Aerobic Composting Workshop of a Large Sludge Treatment Engineering

Based on measured ventilation condition in thebuiltaerobic composting plant of large sludge treatment engineering,usingthe methord of CFD, four kinds of scheme for the new aerobic composting plantwere analysed,which contain two types of ventilation(natural air supply mechanical exhaust and mechanical air mechanical ventilation)and two kinds of supply air rates (4x10(5)m(3)/h and 8x10(5)m(3)/h). Studies have shown that the methord of mechanical air supply and exhaust is better than the original natural air mechanical exhaust in this plant; Themethord of mechanical air supply andexhaust is recommended to reduce ammonia content for personal breathing zone and ventilation energy consumption.
