Description
Technical field
Invention is related to composting recycling field, particularly a kind of aerobic composting device for mixing various garbage and side
Method.
Background technology
With the development and the increase of population of China's urban economy, environmental pollution is increasingly serious.And people's environmental consciousness
Strengthen and increasing waste water is needed processing the raising of environmental quality requirement.It is general with sewage treatment facility
And, the raising for the treatment of capacity and the in-depth of degree for the treatment of, the yield of sludge will have larger growth, China's municipal sludge in 2016
Break through 35,000,000 tons.The outlet for resolving so a large amount of sludge has become very urgent task.Sludge landfill processing disposal
Limited by soil, there is the deficiencies such as filtrate seepage, gas are discharged, the ground caved in；Sludge incineration cost of disposal is high, having in sludge
Evil material can just be decomposed more than 850 DEG C, and burning disposal energy consumption is larger, and the heavy metal in flue gas needs processing.Sludge high temperature is good
Oxygen compost is to realize sewage sludge harmlessness, minimizing, stabilisation, a kind of effective treating method of recycling.
In addition, the resource yield such as the kitchen garbage of China, feces of livestock and poultry and forest and agricultural biomass is constantly highlighted.Kitchen garbage is
Through the 60%-80% for accounting for house refuse；Crop material, timber processed side product, garden and street fallen leaves and the branch of trimming
The residue yield such as bar branch is huge.Because agricultural wastes or directly burning or random heap are abandoned, agricultural production is badly influenced
