Description

Technical Field

[0001] The utility model relates to the technical field of domestic waste treatment, and specifically relates to a dehydration device for domestic waste treatment. Background Art

[0002] Domestic waste management refers to the treatment of solid waste generated in daily life or in activities that provide services for daily life. This includes source reduction, cleaning, classified collection, storage, transportation, treatment, disposal, and related management activities. Its purpose is to reduce waste production, with criteria including volume reduction, harmlessness, and resource utilization. Dehydration is required during domestic waste treatment. The primary purpose of dehydration is to reduce the water content and volume, making it easier to transport, store, and process various treatment and disposal processes. This process not only helps reduce the total volume of waste but also makes it easier to manage and handle. The most common type of waste is kitchen waste. Improper storage can emit foul odors, cause disease, and pollute the environment with organic matter, pathogens, and other toxic and hazardous substances. To recycle this resource, some kitchen waste can be fermented with biological bacteria or other auxiliary materials to convert it into bio-organic fertilizer for reuse. However, direct dehydration of this waste is inconvenient, as adding bacteria and other procedures are not convenient. Furthermore, the waste is mixed with wastewater containing a large amount of pathogens. If not properly treated, this waste will result in the waste of bacteria and the failure of the bio-organic fertilizer to be converted. Utility Model Content
