Description

Technical Field

[0001] The invention belongs to the technical field of garbage resource recovery, and in particular relates to a small-scale domestic garbage and kitchen garbage high-efficiency resource recovery integrated system for islands and remote areas. Background Art

[0002] As small pieces of land scattered in the ocean, islands play a key role as frontier bases in the process of marine development. Island tourism development has always been an important part of marine development and coastal area construction, and is also one of the hot spots in the current marine economic development. As a large marine region, it has rich island tourism resources. With the deepening of tourism development, island tourism is also developing rapidly. The development of island tourism can not only make more effective use of marine resources and bring considerable social and economic benefits to regional construction, but it may also have a negative impact on the ecological environment of islands and surrounding oceans. Among the many potential sources of environmental pollution, domestic garbage and kitchen waste generated in people's lives and production processes are both the main and more difficult to control sources of pollution.

[0003] Island is a special geographical type, with many obvious differences compared with the mainland. Generally speaking, the connection between islands and the mainland, and between islands is very weak. It is precisely because of this that the transportation between islands and between islands and the mainland is very inconvenient, which is not conducive to the flow of materials. Therefore, most developed islands have formed a relatively single socio-economic structure. The difficulty in supplying electricity, fresh water, and means of production on the island has led to high living and construction costs on the island. The island ecosystem refers to the biological community and non-biological environment of the island and its surrounding waters. As a component of the ocean, the island plays an important role in the marine ecosystem. However, compared with the land, the island environment is unique, the ecological conditions are harsh, the vegetation species are poor, the dominant species are relatively obvious, the ecosystem is relatively fragile, and it is extremely easy to be destroyed, and it is difficult to recover after destruction. All this shows that the island has a small carrying capacity for pollutants, that is, the environmental capacity of the island is small.

[0004] The patent with the authorization announcement number CN 112845504 B discloses a process for resource utilization of domestic waste, which includes: crushing and pretreatment; low-temperature cracking; cracking slag selection; carbon powder purification device; energy recovery; leachate and desorption oil and water treatment; cleaning of scrap metal and sewage treatment. The patent invents a process and equipment for resource utilization of domestic waste using low-temperature cracking technology, which can effectively overcome the secondary pollution problem of dioxins caused by incineration, and completely realize the harmlessness, reduction and resource utilization of domestic waste. The low-temperature cracking technology has many advantages. During the low-temperature cracking process, the organic components in the garbage can be converted into usable energy forms, which is more economical. The fuel gas (non-condensable gas) generated by low-temperature cracking can be directly burned or mixed with high-calorific value fuel gas depending on its calorific value. The amount of flue gas generated by the low-temperature cracking method is less than that of the incineration method, which is convenient for flue gas purification.

[0005] The patent with application announcement number CN 114042733 A discloses a comprehensive treatment process for resource utilization of domestic waste, including: crushing and screening domestic waste in sequence, screening into large and small categories; then separating the large categories into heavy and light categories through a specific gravity air separator; then adding a fermentation agent to the light categories for rapid fermentation, and aerobic fermentation of the biological organic matter in the light categories; then screening the fermented light categories into humus, drying the remaining light categories, and then friction dry cleaning; the materials after friction dry cleaning are subjected to magnetic vortex sorting to sort out iron and non-ferrous metal mixtures and plastic film-like substances; finally, plasticizing and polymerizing the plastic film-like substances, and then crushing and grinding them, and finally extrusion and injection molding to obtain plastic products. The comprehensive treatment process for resource utilization of domestic waste of this invention embodiment separates plastic and plastic film-like substances from domestic waste, avoiding the plastic materials from being treated as pollutants in other sorting and treatment processes.

[0006] The patent with the authorization announcement number CN 104070051 B discloses a method for sorting household waste resources and cleaning, including: breaking bags after disinfection and deodorization; tearing into 1-25cm and then disinfecting and deodorizing again; crushing the treated household waste, squeezing out the crushed waste, and the squeezed waste liquid enters the anaerobic fermentation system, and the squeezed waste is sorted through a 2-15mm garbage screen; the screened material after sorting falls into the water, passes through a 50-100 mesh screen, and the obtained pulp is dehydrated and wrung out to obtain a crude pulp product, and the heavy material after separating the pulp, after clearing the mud and sand, enters the building material production line to sort out non-ferrous metals, and then makes building materials; the screened material enters the flotation water tank, and the plastic and other materials with lighter specific gravity are separated from it, and flow with water to a screen with an aperture of 1-5mm, and then it is dried and dehydrated, and then transported to the plastic finishing production line. This method realizes the effective separation of household waste, and finally all of it is processed into products, achieving zero incineration, zero landfill, and zero emission.

[0007] The patent with the authorization announcement number CN 102407232 B discloses a method for recycling domestic waste resources, which is characterized by the following steps: a. water seepage treatment; b. oil-water separation of the water phase and refined treatment of the oil phase; c. high-temperature disinfection, sterilization, shrinkage, reduction, and volume reduction treatment, and entering the grading screen for primary classification; d. primary classification after baking; e. selection of the above-mentioned sorted residues; f. biogas fermentation; refining biodiesel; heating system combustion. Beneficial effects of the invention: The present invention processes and recycles the kitchen waste fully, solves the problems of wastewater and waste gas, achieves high efficiency, energy saving, low consumption, environmental protection, and low cost of transformation into treasure, and achieves the goal of circular economy. Beneficial effects of the invention: The urban domestic waste is fully recycled and utilized, and the problems of wastewater and waste gas are solved, and the problems of wastewater and waste gas are achieved, and the high efficiency, energy saving, low consumption, environmental protection, and low cost of transformation into treasure are achieved, and the goal of circular economy is achieved.

[0008] The patent with the authorization announcement number CN 102371266 B is a method for resource utilization of restaurant kitchen waste, which includes the following steps: a. high temperature instant sterilization and preservation of collected restaurant kitchen waste; b. removal of free water and grease in the restaurant kitchen waste; c. preparation of biodiesel by oil-water separation and exchange reaction of liquid phase, and wastewater treatment; d. magnetic separation, further dehydration; e. catalyst treatment; f. combustion heat energy conversion; g. separation of liquid phase from oil and water to remove its colloid, used as fuel oil, and the water phase enters the wastewater treatment stage. The beneficial effects of the invention: the present invention processes restaurant kitchen waste for full recycling, solves the problems of wastewater and waste gas, and achieves high efficiency, energy saving, low consumption, environmental protection, low cost of transformation and treatment, and realizes the goal of circular economy.

[0009] However, the technical solution of CN 112845504 B focuses on the harmless disposal of screened organic waste using low-temperature pyrolysis technology, which is actually not suitable for production applications on islands (and remote areas); the technical solutions of CN 114042733 A and CN104070051B focus on the simple screening of domestic waste using a combination of equipment and processes, and do not have a resource-based production process for intelligent identification, sorting, and combination with kitchen waste; the technical solutions of CN 102407232 B and CN 102371266 B focus on the resource-based disposal of kitchen waste. On the one hand, their production processes are relatively complicated and are not suitable for production applications on islands (and remote areas) (such as production of biodiesel from crude oil), and on the other hand, products such as biogas are not used in the process, and kitchen waste is not efficiently recycled, and joint production is not achieved with domestic waste.

[0010] At present, there are also some patents involving the coordinated treatment of restaurant and domestic waste. For example, the invention with patent publication number CN117925381A discloses a recycling disposal system and method for island life and tourism waste. The invention adopts the above-mentioned efficient recycling disposal system to achieve the stable disposal of perishable waste such as kitchen waste, straw, grass and trees, and combustible waste such as waste paper and waste clothing generated by island life and tourism, effectively avoiding the problems of unstable fermentation biogas production, poor incineration effect and large pollution faced by single disposal, saving construction costs and disposal costs. The invention with patent publication number CN220379674U discloses a system for the coordinated disposal of urban pollutants by garbage incinerators, including a garbage incineration power plant, a restaurant and kitchen waste treatment plant, a sludge drying disposal device, a slag comprehensive utilization plant, a leachate and sewage treatment station, and a fly ash landfill. The invention with patent publication number CN214289972U discloses a coordinated treatment device for kitchen waste and domestic waste, the invention with patent publication number CN212041970U discloses a solid hazardous waste coordinated domestic waste incineration treatment system, and the invention with patent publication number CN210023209U discloses a garbage treatment station, etc., which can simultaneously treat kitchen waste and domestic waste, and use biogas to burn combustible waste. However, these existing technologies either have large equipment scales and each garbage treatment plant still needs to be managed separately, and are not suitable for islands and remote areas. Although inventions such as CN117925381A involve the coordinated treatment of island life and tourism garbage and can use biogas, the treatment of garbage is very simple and the garbage recycling rate is low. In addition, the garbage treatment device of the prior art does not take into account the specific needs of the unique local natural resources and application scenarios, and the structural model is single, which also reduces the garbage recycling rate from another aspect.

[0011] Therefore, there is an urgent need for a garbage disposal system that can fully take into account local actual conditions and meet the needs of efficient resource disposal of domestic garbage and kitchen waste in islands and remote areas. Summary of the invention

[0012] Technical problems to be solved: Based on the above status quo and needs, the present invention proposes an integrated system for the efficient resource utilization of small-scale domestic waste and kitchen waste on islands and remote areas. The system can be combined with the unique local natural resources and the specific needs of the application scenarios to coordinate the disposal of domestic waste and kitchen waste generated on the islands (or in remote areas), fully realize the harmlessness of the waste and the efficient resource disposal of the products, solve the actual difficulties in the local area, and fill the current market gap.
