Aerobic Drum Composting System

The Aerobic Drum Composting System is a fully enclosed, slow rotating fermentation drum tank. The raw materials and excipients slowly moved to the discharge section, and during the process, the materials are mixed and oxygenated, to provide a superior growth environment for microorganisms, rapid aerobic fermentation reaction to achieve material heating and to accelerate the degradation of organic matter. Microorganisms consume the heat generated when the organic matter is metabolized, so that the material maintains a high temperature period of 55-70 ℃ for more than 3-5 days, which can effectively kill pathogenic bacteria, parasite eggs and weed seeds, and evaporate the water, so that the sludge is converted into a stable humus, and finally realize the stabilization, harmlessness, and volume reduction. The final products can be used for landscaping, soil improvement, etc., and finally realize the resource utilization of the sludge.
Well mixed and Highly transfer efficiency , better fermentation effect
Good thermal insulation sealing , less affected by season and region
Discharge stable, standard indicators of decay and ripeness
Occupies a small footprint and flexible layout
Highly automated, easy to maintain
Fully captured and processed exhaust gas , Environmentally friendly

Application Areas

Sludge Treatment

Livestock Manure Treatment

Food Waste Treatment

Garden Waste Treatment

Performance Metrics

This technology can effectively kill pathogenic bacteria, parasitic eggs, weed seeds, evaporate water, transform solid waste into stable humus, and finally realize solid waste stabilization, harmlessness, and reduction treatment, and the matured products can be used for landscaping, soil improvement, etc., and finally realize the utilization of resources.   

After the aerobic drum fermentation treatment, the moisture content of the product < 40%; The degradation rate of organic matter ≥ 50%; Helminth egg mortality rate > 95%; The fecal coliform bacteria value > 0.01; the seed germination index ≥ 75%. According to the actual efficiency, in terms of sludge treatment effect, from the moisture content, organic matter degradation rate, worm egg death, etc., can meet the relevant requirements of "Sludge for Land Improvement of Urban Sewage Treatment" (GB/T24600-2009), "Sludge for Urban Sewage Treatment Plant Sludge Disposal Landscaping " (GB/T23486-2009) and so on.
