The scope of composting tower can be explained in detail from multiple aspects such as definition, type, and application scenarios.
Definition and type
Composting tower is a kind of equipment used for organic waste treatment, which mainly converts organic waste into fertilizer through the action of microorganisms. According to the structural characteristics, composting towers can be divided into the following categories:
Vertical multi-layer cylindrical composting fermentation tower: This type of composting tower has a vertical multi-layer cylindrical structure, with good insulation, ventilation and stirring functions, and is suitable for the composting fermentation process of organic matter such as agricultural waste and urban domestic waste. Silo-type static fermentation silo: This type of composting tower is mainly used for static fermentation and is suitable for large-scale organic waste treatment. Box-type composting fermentation tank: Including rectangular fixed type, fan bucket tipping type, crane tipping type and horizontal paddle fermentation tank and other types, suitable for composting needs in different scenarios. Application scenarios
Composting towers are widely used in the following scenarios:
Agricultural waste treatment: In the agricultural field, composting towers are used to treat crop straw, livestock and poultry manure, etc., converting these wastes into organic fertilizers to improve soil fertility.
Urban domestic waste treatment: Kitchen waste, garden waste, etc. in urban domestic waste can also be treated by composting towers to reduce the amount of landfill and realize resource utilization.
Environmental protection facility construction: In some environmental protection facilities, composting towers are used to treat high-concentration organic wastes such as sludge from urban sewage treatment plants to reduce environmental pollution.
Design and maintenance
The design of composting towers needs to consider multiple factors, including treatment scale, process requirements, site conditions and economic costs. Reasonable size design is crucial to the composting effect. Usually the tower height is between 5 and 15 meters, the diameter is between 3 and 8 meters, and the number of layers is usually 3 to 6 layers. In terms of maintenance, regularly clean and maintain the ventilation system, stirring device, etc. to ensure the smooth progress of the fermentation process.
