[0048] Embodiment 1: The present embodiment is a stale garbage treatment method, and the final product obtained by the method is an adsorbent material, which specifically comprises the following steps:

[0049] S1, crushing and screening the stale garbage to obtain humus soil with a particle size meeting the preset requirements. The degree of crushing and screening directly affects the particle size and specific surface area of the humus soil, thereby affecting the performance of the adsorbent material. By adjusting the conditions of crushing, screening and mixing, the particle size and composition of the humus soil can be controlled, and the adsorption performance of the adsorbent material can be improved.

[0050] In this example, the screening should be carried out through a screen with a screen hole size not less than 200mm to remove large particle building waste in the stale garbage, and through a screen with a screen hole size of 10mm to remove small particles and small plastics in the stale garbage, and finally obtain stale garbage under-screen soil which can be used for resource utilization and which is free of large sandstone and large plastic.

[0051] The stale garbage is from municipal solid waste landfills, agricultural waste, industrial waste, construction waste landfills, and other mixed landfills. In practical applications, the appropriate stale garbage can be selected according to the local garbage source and processing needs. For complex sources of stale garbage, pretreatment measures such as classification, screening, and cleaning can be taken to improve its resource utilization rate.

[0052] S2, using solar heat drying treatment at 105℃, the moisture content of humus soil is reduced to 2%~8%, or other 3d moisture content has no obvious decrease. The heat drying treatment can remove the excess water in the humus soil and improve its dryness, which is beneficial to the subsequent mineralization treatment. By adjusting the temperature and time of heat drying, the moisture content and dryness of the humus soil can be controlled, thereby affecting the adsorption performance and stability of the adsorption material.

[0053] In the solar heat drying device, high-efficiency collectors are used to improve the utilization rate of solar energy. The collector can adopt flat plate type, vacuum tube type and other structures, and the appropriate type and specification can be selected according to the actual needs. At the same time, temperature control and humidity control systems are equipped to realize accurate control of the heat drying process. By improving the utilization rate of solar energy and control accuracy, the performance and yield of the adsorption material can be improved.

[0054] S3, through solar power generation to drive the rotary kiln, the humus soil is mineralized and carbonized at 650℃ to obtain humus soil powder. The high-temperature mineralization treatment of the rotary kiln can promote the carbonization of organic matter and the release of heavy metals in the humus soil, improving its adsorption performance. By adjusting the temperature and speed of the rotary kiln, the mineralization and carbonization degree and speed of the humus soil can be controlled, further optimizing the performance of the adsorption material.

[0055] In the solar power generation driven rotary kiln, high-efficiency solar cell panels are used to improve the conversion efficiency of solar energy. The solar cell panel can adopt single crystal silicon, polycrystalline silicon and other types, and the appropriate specification and installation method can be selected according to the actual needs. At the same time, an automatic control system is equipped to realize accurate control of the temperature and speed of the rotary kiln. By improving the conversion efficiency of solar energy and accurate control, the performance and yield of the adsorption material can be improved.

[0056] S4, adding composite gelling agent and passivation agent to the humus soil powder, stirring and mixing uniformly to obtain the adsorption material. The passivation agent such as CaO and fly ash is used to passivate heavy metals such as Zn and Cd in the humus soil. The gelling agent is used to promote the coagulation of the humus soil powder, improving its formability and stability. By adjusting the addition amount of the composite gelling agent and passivation agent, the performance and stability of the adsorption material can be further improved.

[0057] Humus powder, composite gelling agent and passivator should be added according to the final particle composition of humus powder and gelling characteristics. The addition of passivator should be determined according to the heavy metals contained in humus.

[0058] S5, various shapes of adsorbent materials are prepared by extrusion balling machine, square mold and other equipment. Different shapes of adsorbent materials have different application scenarios, such as spherical adsorbent materials are suitable for suspended solids removal in water treatment, and square adsorbent materials are suitable for heavy metal ion adsorption in soil remediation. By adjusting the equipment parameters and mold shape, adsorbent materials with desired shape, size and performance can be prepared.

[0059] In this example, a closed system is used in the composting process to reduce energy loss and environmental pollution. The closed system can reduce dust and harmful gas leakage, improve the safety and environmental protection of production. At the same time, the waste heat and surplus energy in the production process can be recycled and utilized, improving the energy utilization efficiency. By using a closed system, an efficient and environmentally friendly adsorbent material preparation process can be achieved.

[0060] In this embodiment, other additives or modifiers can be added during the composting process (adsorbent material preparation process) to further improve the performance of the adsorbent material. For example, activated carbon, metal oxides and other materials with excellent adsorption performance can be added to improve the adsorption capacity and selectivity of the adsorbent material; or surfactants, coupling agents and other modifiers can be added to improve the surface properties and wettability of the adsorbent material. By adding appropriate additives or modifiers, the application range of adsorbent materials in various fields can be further expanded. The addition of activated carbon, metal oxides, surfactants and coupling agents should be tested according to the subsequent adsorption effect and different application scenarios.

[0061] This embodiment can greatly reduce the dependence on natural resources and environmental pollution by converting composted waste into high-value adsorbent materials. At the same time, it provides a new idea and method for waste resource utilization and the development of low-carbon and environmentally friendly technologies.
