Research on the Technology of Integrated Equipment Aerobic Composting for the Treatment of Garden Waste
With the improvement of environmental construction level in Beijing,the area of forest and green space continues to increase,and the amount of garden waste generated is constantly increasing.Aerobic composting can decompose and transform garden waste into humus.This paper studies the process parameters of integrated equip-ment composting for treating garden waste.The optimal process parameters of integrated equipment are obtained.①aeration:ventilation rate is 6 m3/h;aeration interval is 25 minutes,and aeration duration is 5 minutes.②stirring:Stir the material once on the 4th day of composting.③particle size:The optimal particle size range for tree branch waste is 10～30 mm.④microbial agents:When the C/N is 30～50,the proportion of microbial agents added should not be less than 4％.The research results were used to test the application effect in demonstration projects,and the results showed that the process parameters obtained from the study can effectively guide practice.The composting of garden waste reached maturity after 15 days.
