Abstract
Description
Technical Field
[0001] This invention belongs to the field of waste recycling, and specifically relates to an industrial device for the graded utilization of solid waste. Background Technology
[0002] With the acceleration of global urbanization, industrialization, and consumption upgrading, the amount of solid waste generated is growing exponentially. The existing solid waste treatment has long relied on the "landfill as the main method and incineration as a supplementary method" model, which has significant drawbacks: First, landfill land resources are scarce. The remaining capacity of landfills in first-tier cities in China is generally less than 5 years. "Illegal landfilling" leads to heavy metals and persistent organic pollutants (POPs) polluting the soil and groundwater through leachate, with remediation costs reaching hundreds of thousands of yuan per acre. Second, incineration releases dioxins (900 times more toxic than arsenic) and heavy metal dust, achieving only "volume reduction" without resource recovery, wasting organic matter and metal resources. Third, open burning of agricultural solid waste causes regional smog, and the indiscriminate dumping of livestock and poultry manure exacerbates the greenhouse effect and eutrophication of water bodies.
[0003] Existing solid waste treatment technologies suffer from low resource utilization rates and long remediation cycles, and also exhibit significant shortcomings in classification and treatment: Treatment of traditional Chinese medicine residue often remains at the level of simple composting, failing to explore its medicinal components and compatibility with specialized planting soils, resulting in the waste of raw materials for antibiotic-resistant veterinary drugs and soil resources for traditional Chinese medicine cultivation; horticultural crop and vegetable straw are mostly burned or directly returned to the field, failing to achieve the purification and utilization of nutrients in the sap and the transformation of straw into feed; and there is a lack of customized pretreatment processes for different solid waste characteristics, such as using sludge treatment processes for slag soil without dewatering, leading to redundant energy consumption. Simultaneously, existing solid waste treatment technologies suffer from efficiency bottlenecks and functional fragmentation: traditional single-stage composting or anaerobic digestion processes have low organic matter conversion rates (<50%) and long treatment cycles; remediation processes rely on manual experience for control, resulting in low precision and high energy consumption; and solid waste treatment and soil remediation are disconnected, failing to achieve synergistic "resource-remediation" integration. Therefore, there is an urgent need for an integrated system that can achieve efficient solid waste conversion, deep soil remediation, and full-process pollution control. Summary of the Invention
[0004] In order to address the problems of low resource utilization rate and long remediation cycle in existing solid waste disposal technologies, as well as the significant shortcomings in classification and treatment, this application designs an industrial device for the graded utilization of solid waste, in order to enhance the pretreatment of solid waste classification, expand the high-value product chain, upgrade the intelligent control system, and realize the classification, on-demand conversion, and diversified output of solid waste.

This embodiment primarily introduces an industrial equipment design for the graded utilization of solid waste. Through a fully integrated design of "pretreatment-multi-stage conversion-purification-finished product," combined with bioconversion, intelligent monitoring, and material modification technologies, a solid waste-soil co-utilization system is constructed. The specific technical solution is as follows: (1) Overall system architecture The system comprises six core modules: raw material pretreatment unit, multi-stage biological conversion unit, intelligent control unit, flue gas purification unit, wastewater treatment unit, and finished product treatment unit. Each module is connected in series through equipment such as belt conveyors and screw pumps to achieve continuous treatment of solid waste from feed to finished product, while achieving near-zero emissions through flue gas and wastewater purification.
[0026] (2) Detailed design of core modules Raw material pretreatment unit: Customized pretreatment processes for different solid waste characteristics Sludge-type solid waste: It is processed through "sampling and testing → sludge preparation (adding cell wall breaking / biological deodorizing agents) → wet material entering the silo → ultra-high pressure belt filter press dewatering (moisture content 40%-90%) → dry material storage → coarse crushing → fine crushing → powdering → sorting and dewatering" to remove impurities and adjust the moisture content to a suitable range for biological transformation. Chinese medicine residue solid waste: Add a "solid-liquid separation in the carriage" step, where the liquid material is used to prepare antibiotic-free veterinary drug intermediates, and the solid material enters the crushing and pulverizing process, while realizing the graded utilization of the effective components in the residue. Horticultural straw solid waste: The juice is collected through "pressure filtration → dry and wet separation" (to prepare soil nutrient supplement solution), and the solid material enters the crushing process after secondary dehydration, thereby improving resource utilization.
[0027] Multi-stage biological conversion unit: Breaking through the bottleneck of traditional single-stage treatment, it adopts a three-stage series structure of "anaerobic fermenter (stage I) - aerobic composting bin (stage II) - post-ripening aging tank (stage III)" with a volume ratio of 1:2:1. A 45° inclined guide pipe ensures uniform material flow, and the functions of each stage are clearly defined. Stage I anaerobic fermenter: Equipped with a built-in spiral agitator and microporous aerator, and supplemented with AQDS redox mediator (50-100μM) to promote the hydrolysis and acidification of complex organic matter and electron transfer, increasing the methanogenesis rate by 40%; Level II aerobic composting bins: The double-layer jacket structure achieves heat preservation, the tracked turner (turning depth 20-30cm) ensures uniform oxygen supply, and the E.coli S30 cell-free system is introduced to synthesize lignin peroxidase (enzyme activity 200U / mL) to accelerate the degradation of recalcitrant organic matter (such as lignin). Level III post-maturation aging tank: The honeycomb biological filter layer (made of coal gangue-sludge composite modification, with a porosity of >60%) is inoculated with nitrogen-fixing bacteria and phosphorus-solubilizing bacteria to achieve slow release of nutrients and colonization of microorganisms, thereby improving the fertility of the finished soil.
[0028] Intelligent control unit: Enables dynamic optimization throughout the entire process, constructing a multi-parameter online monitoring network and central control system. Sensor deployment: The anaerobic tank is equipped with an ORP sensor and a VFA detector to monitor the acidification process in real time; the aerobic chamber is equipped with a CO2 / O2 sensor to adjust the aeration rate (0.5-2.0 m³ / h); the remediation zone is equipped with distributed fiber optic temperature sensors and three-parameter probes (EC, pH, moisture content) to provide early warning of contaminant migration. Data transmission and control: Data is transmitted to the DCS central control system via a LoRa wireless module (spreading factor 7-12). Combined with PID algorithm and AI recognition, the operation of the equipment can be remotely controlled (e.g., in the Shanghai central control room), reducing energy consumption by 30%.
[0029] Flue gas and wastewater treatment unit: Full-process pollution control Flue gas purification: A five-stage process is adopted, consisting of "cyclone dust removal → multi-tube dust removal → bag dust removal → activated carbon adsorption → water mist dust collection". The end-of-pipe flue gas monitoring instrument ensures that emissions meet the standards (dioxin and particulate matter concentrations meet national standards). Wastewater treatment: The process involves a steel sludge sedimentation tank, an air flotation machine, a biological purification tower, and an integrated RO / MBR system. The effluent is used as industrial diluent, and the sludge is returned to the dewatering module, thus achieving water resource recycling.
[0030] Finished Product Processing Unit: Produces high-value-added products in a tiered manner. Based on the type of solid waste and the conversion effect, the output includes: Basic products: organic planting soil, construction site purified backfill soil, tailings filling purified soil (compliant with GB36600-2018 and T / CSTM 00505-2024 standards). Specialized products: Specialized planting soil for Chinese medicinal herbs (suitable for the growth needs of Chinese medicinal herbs), antibiotic-free veterinary drug intermediates (derived from Chinese medicinal herb residue), and soil nutrient supplement solution (derived from straw juice).
[0031] Example 2: The following is a detailed explanation of the implementation process of this system, using a project example from Shanghai as an example: I. Project Background This project addresses the solid waste treatment needs of Shanghai and surrounding areas, with a designed processing capacity of 50 tons / day. It mainly treats three types of solid waste: sludge, traditional Chinese medicine residue, and horticultural straw, and aims to produce organic planting soil, special soil for traditional Chinese medicine, and soil nutrient supplement solution.
[0032] II. Equipment Configuration (Refer to the project equipment list)
[0033] III. Implementation Steps (1) Sludge treatment process (core process) 1. Sampling and testing: After the solid waste transport vehicle (GPS positioning) enters the plant, samples are taken to the laboratory. The process of "sample drying → powdering → preparation of standard solution / sample solution → elemental detection" is carried out to determine the content of heavy metals (Cd, Pb) and organic matter in the sludge. The data is then transmitted to the DCS system. 2. Preparation and Dewatering: The sludge enters a stationary mixing tank, and cell wall breaking agent (concentration 0.5%) and biological deodorizing agent (concentration 0.3%) are added. After being stirred evenly, it is transported to an ultra-high pressure belt filter press through a screw pump to dewater to a moisture content of 60%. 3. Crushing and grinding: Dewatered sludge is fed into a compound crusher via a belt conveyor and crushed to a particle size ≤5mm. It is then processed by a grinding mill to a particle size ≤1mm and impurities are removed by a heavy-duty shaftless screen. 4. Multi-level biotransformation: Stage I anaerobic fermentation: The material enters the anaerobic tank, AQDS (concentration 80μM) is added, the temperature is maintained at 35℃, the ORP is controlled at -300~-200mV, and the mixture is held for 12 hours to complete the hydrolysis and acidification. Level II aerobic composting: The material enters the aerobic chamber, and the tracked turner turns it once every 2 hours. The aeration rate is 1.5 m³ / h, maintaining an oxygen content of 18% and a temperature of 58℃. A cell-free system is introduced to synthesize LiP, and the material stays for 24 hours. Level III post-maturation aging: The material enters the aging tank, is inoculated with nitrogen-fixing bacteria through the honeycomb filter layer, and stays for 12 hours to complete the slow release of nutrients; 5. Finished product processing: After aging, the material is bagged by a bagging machine (25kg / bag), weighed, and then put into storage. The finished product test shows that the organic matter content is ≥30% and the Cd leaching concentration is ≤0.3mg / L, which meets the standards for organic planting soil. 6. Pollution control: Dust generated during the crushing and grinding process is treated by the flue gas purification system, and the concentration of particulate matter emitted is ≤10mg / m³; wastewater generated during dewatering is treated by MBR equipment, with the effluent used for reagent dilution and the sludge returned to the filter press.
[0034] (2) Processing flow of Chinese medicinal herb residue (derived products) 1. Solid-liquid separation: After the Chinese medicine residue is transported to the factory, the liquid and solid materials are separated by a solid-liquid separation device in the truck compartment, and the liquid materials are stored in a special storage tank. 2. Solid-state treatment: After dehydration (50% moisture content), crushing and pulverizing, the solid Chinese herbal medicine residue enters a multi-stage biological transformation unit. The temperature of the aerobic chamber is adjusted to 55℃ to produce special soil for Chinese herbal medicine (testing shows pH=6.5-7.0, suitable for the growth of Chinese herbal medicines). 3. Liquid processing: After filtration and purification (removal of impurities), the liquid material is tested for the content of effective ingredients, and then filled into antibiotic-free veterinary drug liquid intermediates for storage and shipment. Implementation effect
[0035] After three months of operation, the project has processed a total of 4,500 tons of solid waste, producing 2,800 tons of organic planting soil, 800 tons of soil for traditional Chinese medicine, and 200 tons of antibiotic-free veterinary drug intermediates, generating sales revenue of 1.26 million yuan. The treatment cost has been reduced by 40% compared to traditional landfill, the flue gas emission compliance rate is 100%, and the wastewater reuse rate is 80%.
