[0018] Working principle of the utility model fresh domestic waste resource system:

[0019] 1. Multi-stage sorting system for domestic waste

[0020] The purpose of sorting fresh domestic waste is to separate the waste into light materials, organic matter, inorganic aggregates (inorganic components) and metals according to the material composition and final disposal requirements through mechanical screening.

[0021] The multi-stage domestic waste sorting system receives fresh domestic waste. Garbage trucks unload the waste into the storage hopper of a chain apron feeder. The waste is then transported by the chain apron feeder and a leveler to a belt conveyor. The belt conveyor then transports the waste to a manual sorting room, where workers manually sort out large and inert materials that could interfere with subsequent crusher operation and drop them into a receiving bin below the platform.

[0022] The remaining materials are then transported by a chain feeder to a belt conveyor, screened by the first drum screening machine, and transported to the first manual sorting room for manual sorting. The sorted plastic bottles and other large plastics are packaged and compressed for sale, while the sorted tiles, ceramics, glass, and other inert substances are disposed of in landfills.

[0023] The material is screened by the first drum screening machine into oversize and undersize.

[0024] The material on the first drum screening machine: The material on the screen enters the positive pressure integrated air separator by a belt conveyor. After the positive pressure integrated air separator sorts the materials, the light materials after air separation are mainly plastic materials and fabrics and other combustibles. They are transported by a belt conveyor to the first magnetic separator for metal recovery. The remaining light materials are transported to the light material temporary storage area by a belt conveyor, and then crushed by a crusher. After crushing, they are transported to the biomass fuel production line to produce biomass fuel rods for sale. The heavy materials after air separation are transported to the first manual sorting platform for sorting by a belt conveyor. The sorted materials are transported to the aggregate temporary storage area by a belt conveyor. Large plastics such as plastic bottles are packaged and compressed for sale. The sorted aggregates such as tiles, ceramics, glass, and other inert materials are disposed of by landfill.

[0025] The undersize material of the first drum screening machine: The undersize material is transported by a belt conveyor to the second magnetic separator. After magnetic separation, the undersize material is transported by a belt conveyor to the second drum screening machine for secondary screening. After the secondary screening, the heavy materials on the screen are separated by the second manual sorting platform, and the light materials are transported by a belt conveyor to the light material temporary storage area, and then enter the fine crusher for crushing and then enter the biomass fuel production line; the organic matter under the screen after the secondary screening is transported by a belt conveyor to the organic matter temporary storage area, and then enters the organic matter fermentation workshop for fermentation treatment. After fermentation treatment, it can be used as soil for greening and transported out.

[0026] The components obtained by the multi-stage sorting system of domestic waste are as follows:

[0027] 1) Sorting out light materials: The light materials after sorting are mainly combustible materials such as plastic materials and fabrics, which are used to produce biomass fuel rods.

[0028] 2) Separation of organic matter: The organic matter under the second drum screening machine is transported by a belt conveyor to the organic matter fermentation system for fermentation treatment to produce organic fertilizer.

[0029] 3) Separate the metals for recycling.

[0030] 4) Manual sorting: sorted plastic bottles and other large plastics are packaged and sold, and sorted inorganic aggregates, glass, and other inert materials are landfilled.

[0031] 2. Organic matter fermentation system

[0032] The sorted organic matter enters the organic matter fermentation system, which is divided into two steps: primary dynamic drum fermentation and secondary fermentation process.

[0033] Primary dynamic drum fermentation: The drum fermentation reactor uses a horizontal drum as an aerobic reactor. The rotation of the drum achieves a full mixing reaction of materials, oxygen, and microorganisms, improves mass transfer efficiency, and achieves stable and harmless treatment of organic matter through biological fermentation, turning organic solid waste into resources. It has no external heat source, low energy consumption, and is fully enclosed and environmentally friendly.

[0034] Secondary fermentation process: The organic matter after the first dynamic drum fermentation is not fully decomposed. Use a loader or belt conveyor to pile the material after the first drum fermentation into strips. After the second decomposition, the organic matter reaches a stable state and can be transported out as soil for greening.

[0035] 3. Leachate treatment system

[0036] The leachate treatment system primarily treats landfill leachate, wastewater from the organic fermentation system, and cleaning wastewater. This leachate is pumped into the regulating tank and then into the anaerobic tank. The effluent from the anaerobic tank flows by gravity into the denitrification tank and then into the nitrification tank for further degradation of pollutants. The remaining sludge is then discharged into the organic fermentation stage for further treatment. Increasing the sludge concentration significantly enhances the microbial degradation capacity of organic matter. Combined with the separation effect of the ultrafiltration membrane, this improves the effluent quality to meet discharge standards.

[0037] This new fresh domestic waste resource recovery system utilizes a "multi-stage waste sorting + organic matter fermentation + leachate treatment" process to treat fresh biochemical waste, achieving waste reduction, harmless treatment, and resource recovery. Through this project, domestic waste classification will be more thorough, with the ultimate goal of increasing waste resource utilization. The multi-stage waste sorting unit separates fresh domestic waste into inorganic aggregates, organic matter, plastics, metals, textiles, and wood and bamboo. Based on local industrial conditions, organic matter is fermented to produce landscaping soil, rich in nutrients such as nitrogen and phosphorus, for use in landscaping, achieving waste resource utilization. High-quality plastics can be recycled and sold. Other non-recyclable combustible materials such as plastics, textiles, and wood and bamboo are crushed and converted into biomass fuel rods for resource recovery. Metals are recycled and sold. Inorganic aggregates such as bricks, tiles, ceramics, glass, and other inert materials are landfilled. This new fresh domestic waste resource recovery system provides strong support for the development of a zero-waste city, achieving the goals of waste reduction, harmless treatment, and resource recovery.

[0038] In addition, the fresh domestic waste resource system of the present invention has the following advantages compared with the existing technology:

[0039] 1) The utility model fresh domestic waste resource system can improve the level of urban domestic waste treatment reduction, resource utilization and harmlessness;

[0040] 2) The utility model's fresh domestic waste resource system can reduce the amount of domestic waste landfilled and extend the service life of existing domestic waste landfills;

[0041] 3) The utility model's fresh domestic waste resource system can save land, maximize water recycling, and avoid waste of resources;
