Description

Technical Field

[0001] The present invention belongs to the technical field of urban waste treatment, and in particular relates to a strongly coupled collaborative treatment method for urban venous industrial park waste. Background Art

[0002] With the acceleration of the global urbanization process, the urban population is growing, and industrial, commercial and residential activities are becoming more frequent, resulting in a sharp increase in the generation of various wastes. These wastes include domestic waste, industrial waste, construction waste and medical waste. They are of various types, complex components and different levels of treatment difficulty. How to effectively treat these wastes, reduce their pollution and harm to the environment, and achieve resource recovery and reuse has become a major challenge facing the current society. Moreover, traditional treatment methods often cannot achieve the maximum recovery and reuse of useful resources in waste. In today's increasingly tight resources, this treatment method is obviously not in line with the concept of sustainable development. Therefore, we propose a strong coupling and coordinated treatment method for urban venous industrial park waste. Summary of the invention

[0003] The purpose of the present invention is to provide a method for strongly coupled coordinated treatment of waste in an urban venous industrial park. Through the strongly coupled coordinated treatment technology of waste, the effective integration of energy and material flows between different types of waste is achieved, and the waste heat generated by metal waste smelting or medical waste incineration is used in the anaerobic digestion process, which not only improves the conversion efficiency of biomass energy, but also reduces the demand for external energy, realizes the internal circulation and efficient utilization of energy, and solves the problem that traditional treatment methods often cannot achieve the maximum recovery and reuse of useful resources in waste. In today's increasingly tight resources, this treatment method is obviously not in line with the concept of sustainable development.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a method for strongly coupled coordinated treatment of waste in an urban venous industrial park, comprising the following steps:

[0006] Step 1: Classification, collection and preprocessing;

[0007] Step 2: Waste disposal;

[0008] Step 3: Strongly coupled coordinated waste treatment;

[0009] Step 4: Information management monitoring.

[0010] The step 1 includes the following sub-steps: Classification and collection: Detailed classification is carried out at the source of waste generation, such as homes, schools, hospitals, factories, construction sites, and preliminary classification is carried out according to the nature of the waste, including recyclables, hazardous waste, kitchen waste, industrial waste and medical waste; the collection team will formulate a detailed collection route map according to the law and distribution of waste generation. During the collection process, the collection team will further classify the waste, and the classified waste will be loaded into different collection containers and transported to the designated treatment center using special transportation tools;

[0011] Pretreatment: For large wastes, such as old furniture, electronic products, industrial debris, and construction site stones, they are crushed to reduce the volume; for loose wastes, such as paper and plastics, they are compressed to improve storage and transportation efficiency; for wastes with high water content, such as kitchen waste and sludge, they are dried to reduce humidity for subsequent processing; through the action of magnetic or electric fields, magnetic or conductive substances in the waste are separated.

[0012] Further, the step 2 includes the following steps: classifying the classified waste into biomass waste, metal waste, plastic waste, medical waste and construction waste;

[0013] The biomass waste treatment includes: anaerobic fermentation: for biomass waste such as kitchen waste, crop straw and other organic matter, anaerobic fermentation technology can be used, the organic waste is placed in an anaerobic reactor and sealed to prevent oxygen from entering. The design of the reactor should ensure that the organic matter can be fully mixed and fully contacted with the microorganisms. The anaerobically fermented organic matter produces methane gas; composting: the pretreated biomass waste is piled in a well-ventilated place to form a compost pile. During the composting process, the temperature will naturally rise. This is due to the heat generated by the metabolic activity of the microorganisms. After composting, the biomass waste is converted into organic fertilizer.

[0014] Furthermore, the metal waste treatment includes: dismantling and impurity removal: preliminary sorting and dismantling of metal waste by sorting equipment and dismantling tools to remove impurities and non-metallic materials, improve the purity and recycling efficiency of metals, and the remainder is the waste residue after dismantling: smelting and casting: smelting the sorted metal, using corresponding smelting processes according to different metal types and properties, and then casting it into new metal products or parts.

[0015] Furthermore, the plastic waste treatment includes: cleaning and crushing: cleaning the plastic waste to remove stains and impurities, and then crushing it into smaller pieces through a crusher to facilitate subsequent processing. After cleaning, it is divided into plastic and wastewater; plastic can be heated and granulated: the crushed plastic fragments are made into plastic particles through heating, extrusion and other processes. These plastic particles can be used to produce new plastic products. Some plastics can also be decomposed into original monomers or chemicals through chemical recycling methods, and then repolymerized into new plastic materials; and the wastewater produces filtered water and sludge after purification.

[0016] Furthermore, the medical waste treatment includes: incineration: using high temperature to thoroughly sterilize combustible medical waste to kill pathogenic microorganisms and other harmful substances therein. Medical waste has a high calorific value, and the heat generated by its combustion can be recycled; sterilization and landfill: for some medical waste that is not suitable for incineration, such as sharp instruments and metal medical waste, strict sterilization treatment is required, and then safe landfill or other disposal methods are carried out.

[0017] Furthermore, the construction waste treatment includes: classification, crushing and screening: using a crusher to crush the construction waste into particles of a certain size, screening the crushed particles through a vibrating screen or other screening equipment to remove impurities therein, and obtaining recycled aggregate that meets the requirements; recycling: using the recycled aggregate to produce recycled concrete, recycled bricks, recycled mortar and other construction materials, or as roadbed materials.

[0018] Furthermore, the strong coupling collaborative treatment of waste includes the following steps: utilizing the waste heat generated by smelting metal waste or incinerating medical waste for the anaerobic digestion process to improve the conversion efficiency of biomass energy; the methane generated after anaerobic digestion can be used for stoves, heating, power stations and industrial fuels; it has the characteristics of high calorific value, low carbon content and high combustion efficiency; the heat generated can provide a heat source for the surrounding biomass waste treatment facilities or for heating buildings; concrete blocks in construction waste, sludge after sewage purification, residues after metal dismantling and organic fertilizers after composting are recycled as soil conditioners or renewable resources to achieve efficient utilization and complementarity of energy; after cleaning the plastic waste, the treated wastewater is reused in the production process or the greening and cleaning links within the park to achieve the recycling of water resources.

[0019] Furthermore, the information management monitoring includes the following steps: corresponding monitoring points are set for different waste treatments to monitor the key parameters in the treatment process in real time. For anaerobic fermentation, temperature sensors, pressure sensors, gas flow meters, pH meters and speed sensors can be set to monitor temperature, pressure, methane production, pH value and stirring speed; for composting process, temperature sensors, humidity sensors, oxygen analyzers, carbon dioxide analyzers and organic content meters can be set to monitor temperature, humidity, oxygen concentration, carbon dioxide concentration and organic degradation rate; for metal smelting and casting, pyrometers, energy consumption monitors, spectrometers and atmosphere analyzers are set to monitor temperature, energy consumption, metal composition and furnace atmosphere; for plastic For the treatment of plastic waste, image recognition systems, particle size analyzers, temperature sensors and quality detectors are set up to monitor the cleaning effect, crushing particle size, heating temperature and granulation quality of plastics; for medical waste, pyrometers, biological indicator testing equipment and gas analyzers are set up to monitor the incineration temperature, sterilization effect and landfill gas emission conditions; for the treatment of construction waste, particle size analyzers, screening efficiency monitors and quality detectors are set up to monitor the crushing particle size, screening efficiency and quality of recycled aggregates; parameter data in the treatment process is collected in real time and transmitted to the central control system through a wireless network, so that the central control system can analyze and process these data to optimize the treatment process and improve the treatment efficiency and quality.

[0020] The present invention has the following beneficial effects:

[0021] 1. The present invention realizes the effective integration of energy and material flows between different types of wastes through the strong coupling collaborative treatment technology of wastes. The waste heat generated by the smelting of metal waste or the incineration of medical waste is used in the anaerobic digestion process, which not only improves the conversion efficiency of biomass energy, but also reduces the demand for external energy, realizes the internal circulation and efficient utilization of energy. In addition, construction waste, sludge, etc. are converted into soil conditioners or renewable resources, and plastic washing wastewater is reused in the production process or the greening and cleaning links in the park, which reflects the maximum recovery and recycling of resources and conforms to the principle of sustainable development.

[0022] 2. The present invention effectively reduces the pollution to the environment caused by direct discharge of waste through classified collection and pretreatment, and strong coupling and coordinated treatment steps of waste, especially the high-temperature disinfection treatment of medical waste, which ensures the safe disposal of pathogenic microorganisms and other harmful substances and prevents the occurrence of secondary pollution. At the same time, the methane produced by anaerobic fermentation is used as a clean energy to replace traditional fossil fuels, which helps to reduce greenhouse gas emissions and combat climate change.

[0023] 3. The present invention provides real-time monitoring and data analysis support for the entire waste treatment process through the introduction of an information management and monitoring system. Through accurate measurement of key parameters such as temperature, pressure, gas composition, and energy consumption, problems in the treatment process can be discovered in a timely manner and adjusted, thereby optimizing the treatment process and improving treatment efficiency and quality. This intelligent management model not only improves operational efficiency, but also enhances the stability and security of the system, providing a scientific basis for achieving refined management and decision-making.
