Due to the different sources and components, there are also differences in the treatment methods of kitchen waste and kitchen waste. Kitchen waste usually needs professional oil-water separation and harmless treatment to avoid environmental pollution, and kitchen waste can be recycled by composting.
Method for treating kitchen waste
1. Physical sorting treatment: the kitchen waste is crushed and sorted by physical sorting equipment, such as crusher and sorter, and impurities are separated to obtain relatively pure organic matter.
2. Biological treatment: the organic matter in kitchen waste is converted into fertilizer or biogas through microbial fermentation. This method can not only reduce the amount of garbage, but also realize the utilization of resources.
3. Heat treatment: the organic matter in the kitchen waste is oxidized or pyrolyzed by technologies such as high-temperature incineration or pyrolysis to obtain heat energy or combustible gas. This method has high treatment efficiency, but the equipment and operation costs are high.
