Abstract
Description
Technical Field
[0001] The utility model relates to an organic waste resource processing system, belonging to the technical field of organic waste processing. Background Art
[0002] Organic waste refers to organic items or materials generated during production, daily life, and other activities that have lost their original value or have been discarded despite retaining their value. It generally includes municipal organic waste, industrial organic waste, and agricultural organic waste. Municipal organic waste includes restaurant and household kitchen waste, industrial organic waste includes processed vegetable, fruit, and meat waste, and agricultural organic waste includes livestock manure and straw. If these organic wastes are not effectively and properly disposed of, they will have a serious adverse impact on the ecological environment.
[0003] Currently, resource utilization of organic waste includes landfilling, composting, and incineration. Landfilling will produce a large amount of leachate that is difficult to handle and costly; composting has a long treatment cycle and low product added value; since organic waste contains a large amount of water, its calorific value is relatively low, and incineration not only easily causes air pollution but also increases the consumption of other energy materials.
[0004] Anaerobic fermentation-based biogas production from organic waste promotes harmless treatment and energy utilization of organic waste. This not only eliminates environmental pollution and produces clean biogas, but also allows the biogas residue to be used as organic fertilizer, meeting the needs of energy conservation, emission reduction, and renewable energy development. However, the disposal of the large amount of biogas slurry generated by biogas projects has become a key factor hindering their development.
[0005] Currently, one approach to treating biogas slurry is to use it as an organic fertilizer resource. However, due to its high production volume and low concentration of crop nutrients, there is generally insufficient land available to absorb it, and long-distance transportation is costly. Furthermore, the agricultural use of biogas slurry is significantly seasonal, requiring ample storage space, resulting in high construction costs. Treating it as wastewater and discharging it to meet standards is also costly and economically inefficient. To achieve zero biogas slurry discharge, existing treatment systems for landfill leachate and fermented biogas utilize an inlet preheater, a desorption tower, a deamination tower, an MVR evaporator, a forced circulation heat exchanger, a biochemical reactor, and a condenser. The fermented biogas wastewater undergoes two thermal extractions to remove most of the ammonia nitrogen, and then condenses to produce ammonia water. Mechanical vapor recompression and forced circulation flash evaporation are then used to remove the remaining ammonia nitrogen and volatile small molecules of COD. Finally, the wastewater is fed into a biochemical reactor for biochemical treatment, and then passes through a condenser to produce regenerated return water. However, this treatment system uses an MVR evaporator to evaporate and desalinate the deammonified wastewater. It can utilize the secondary steam generated by the evaporation system itself and its energy to compress the steam compressor to do work and increase the thermal energy of the secondary steam to reduce the demand for external energy. However, the operating energy consumption still cannot be reduced. In particular, the wastewater contains relatively high hardness ions, which makes the scaling problem particularly serious under the condition of intense evaporation, and the equipment operation stability is poor.

DETAILED DESCRIPTION
[0021] See Figure 1 As shown, an organic waste resource treatment system of the present invention includes an anaerobic reactor 1, a steam boiler 7, a solid-liquid separator 2, a microfiltration membrane assembly 4, a deammonification device 5 and an ozone reactor 6.
[0022] As shown in Figure 1, the anaerobic reactor 1 of the present invention is used to perform anaerobic digestion on organic waste and produce biogas and biogas liquid after degrading the organic matter. The anaerobic reactor 1 of the present invention adopts a CSTR fully mixed anaerobic reactor. The anaerobic reactor 1 has a feed port, a biogas liquid outlet, and a biogas outlet. The organic waste is added to the anaerobic reactor 1 through the feed port. The organic waste can be crushed material, such as organic waste with a particle size between 10-20 mm. The organic waste can also be in liquid phase and added to the anaerobic reactor 1 through a water distribution pipe. The anaerobic reactor 1 is provided with an electric stirrer 1-1 for The organic waste and the anaerobic sludge are mixed and stirred so that the organic waste and the anaerobic sludge containing microorganisms are in a completely mixed state and anaerobic digestion treatment is carried out. First, most of the hydrocarbon organic matter is anaerobically digested, degraded and produces biogas, and organic nitrogen such as protein is converted into ammonia nitrogen. The biogas outlet at the top of the anaerobic reactor 1 is connected to the fuel device of the steam boiler 7 through a biogas pipe, so that the anaerobic biogas is used as the fuel source of the steam boiler 7. The biogas liquid outlet at the top of the anaerobic reactor 1 is connected to the feed port of the solid-liquid separator 2 through a pipeline, and the biogas liquid after the anaerobic reaction is sent to the solid-liquid separator 2 for solid-liquid separation.
[0023] As shown in Figure 1, the solid-liquid separator 2 of the present invention is used to perform solid-liquid separation on the biogas slurry. The solid-liquid separator 2 adopts a horizontal screw centrifuge. The liquid phase outlet of the solid-liquid separator 2 is connected to the water inlet of the microfiltration membrane assembly 4 through a water inlet pipe. The water inlet pipe is provided with a water inlet pump 3. The biogas slurry containing high ammonia nitrogen after anaerobic digestion is sent to the solid-liquid separator 2 for solid-liquid separation through the water inlet pump 3. After the solid-liquid separation, the anaerobic effluent separates the suspended matter and sludge with larger diameters, discharges them and uses them as agricultural fertilizer, while the separated wastewater still contains fine suspended matter. Therefore, the separated liquid enters the microfiltration membrane assembly 4 to further remove suspended matter, colloids and other substances.
[0024] As shown in Figure 1, the microfiltration membrane assembly 4 of the present invention is used to perform membrane filtration on the effluent of solid-liquid separation to remove suspended matter in the water. The clear water outlet of the microfiltration membrane assembly 4 is connected to the deammonification device 5 through a clear water pipe, and the concentrated water outlet is introduced into the lower part of the anaerobic reactor 1 through a concentrated water return pipe. The effluent of the microfiltration membrane assembly 4 is wastewater containing high concentrations of ammonia nitrogen and alkalinity, and the wastewater is mainly composed of bicarbonate ions. The suspended matter retained by the microfiltration membrane assembly 4 is a concentrated solution containing a large amount of organic matter. The concentrated solution is returned to the anaerobic reactor 1 for further degradation to ensure the anaerobic sludge concentration in the anaerobic reactor 1 and prevent sludge loss. The clear liquid treated by the microfiltration membrane assembly 4 then enters the deammonification device 5, which can well solve the problem of easy clogging of the deammonification device 5.
[0025] As shown in Figure 1, the microfiltration membrane assembly 4 of the present invention includes multiple microfiltration membrane elements connected in series, and the water inlets and water outlets of adjacent microfiltration membrane elements are connected and communicated in sequence. Therefore, the wastewater is filtered through multiple microfiltration membrane elements, and the concentrated water outlet of each microfiltration membrane element is connected and communicated with the concentrated water return pipe, and the concentrated water is returned to the lower part of the anaerobic reactor 1 to maintain the concentration of anaerobic sludge in the anaerobic reactor 1.
[0026] See Figure 1 As shown, the deamination device 5 of the present invention includes a deamination tower 5-1, a gas-liquid separation tank 5-2, a carbonization tower 5-5 and a centrifuge 5-8.

The water inlet at the top of the deamination tower 5-1 is connected to the clear liquid pipe, and the mixed gas outlet at the top is connected to the air inlet of the gas-liquid separation tank 5-2 through the mixed gas pipe. The steam outlet of the steam boiler 7 is connected to the steam inlet at the bottom of the deamination tower 5-1 through the steam pipe. The biogas produced by anaerobic digestion is used as the fuel for the steam required by the deamination tower 5-1. The steam generated by the steam boiler 7 It enters from the bottom of the deamination tower 5-1, and under the action of steam stripping, the ammonium bicarbonate in the biogas slurry after deslagging is decomposed into ammonia, carbon dioxide, etc., and the mixed gas enters the gas-liquid separation tank 5-2. The drain outlet at the bottom of the deamination tower 5-1 is connected to the liquid inlet of the ozone reactor 6 through the ozone inlet pipe. The ozone feed pump 5-3 is provided on the ozone inlet pipe. Therefore, after the biogas slurry is deaminated in the deamination tower 5-1, the wastewater is sent to the ozone reactor 6 for ozone oxidation treatment, and the organic matter in the wastewater is further oxidized and degraded.
[0027] See Figure 1 As shown, the gas-liquid separation tank 5-2 of the present invention is used to separate gas and liquid. An air inlet is provided on the top of the gas-liquid separation tank 5-2, and a condenser 5-21 is provided on the upper part. The gas phase outlet in the middle of the gas-liquid separation tank 5-2 is connected to the gas phase inlet of the carbonization tower 5-5 through a pipeline, and the water outlet at the bottom of the gas-liquid separation tank 5-2 is connected to the water inlet of the carbonization tower 5-5 through an ammonia water inlet pipe. After the mixed gas is condensed by the condenser 5-21, the ammonia gas and water vapor are condensed to form ammonia water, and the ammonia water and carbon dioxide gas are separated and discharged into the carbonization tower 5-5 through the corresponding water outlet and gas phase outlet respectively.
[0028] The utility model is to increase the concentration of ammonia water discharged from the gas-liquid separation tank 5-2 to the carbonization tower 5-5. Figure 1As shown, the lower portion of the gas-liquid separator tank 5-2 of the present invention is further provided with a reflux port, located above the water outlet. This reflux port is connected to the feed port at the top of the gas-liquid separator tank 5-2 via a concentration reflux pipe. A circulation pump 5-9 is provided on the concentration reflux pipe, and a carbonizing tower feed pump 5-4 is provided on the ammonia inlet pipe. The concentration reflux pipe can be connected to the mixed gas pipe via a three-way pipe joint. This allows the ammonia at the bottom of the gas-liquid separator tank 5-2 to be continuously refluxed back into the gas-liquid separator tank 5-2 via the circulation pump 5-9, thereby continuously concentrating the ammonia. The concentrated ammonia is then delivered to the carbonizing tower 5-5 via the carbonizing tower feed pump 5-4.
[0029] See Figure 1 As shown, the carbonizing tower 5-5 of the present invention is used to react ammonia water and carbon dioxide introduced into the carbonizing tower 5-5 to generate an ammonium bicarbonate solution. In the carbonizing tower 5-5, the ammonia water continuously circulates and absorbs the carbon dioxide to form a saturated ammonium bicarbonate solution. The carbonizing tower 5-5 is provided with an upper water inlet, a lower gas phase inlet and a bottom discharge port. The discharge port is connected to the feed port of the centrifuge 5-8 through a feed pipe, and a centrifugal feed pump 5-7 is provided on the feed pipe. The water outlet of the carbonizing tower 5-5 is fed into the centrifuge 5-8 through the centrifugal feed pump 5-7 for solid-liquid separation.
[0030] See Figure 1 As shown, the centrifuge 5-8 of the present invention is used to separate crystals in a saturated ammonium bicarbonate solution. A feed inlet is provided at the top of the centrifuge 5-8, and a mother liquor outlet is provided at the bottom. The crystal outlet at the bottom of the centrifuge 5-8 is connected to the storage tank, and the mother liquor outlet is connected to the ammonia water inlet pipe through a mother liquor reflux pipe. A centrifugal reflux pump 5-6 is provided on the mother liquor reflux pipe. The fine crystals in the saturated ammonium bicarbonate solution are separated by the centrifuge 5-8, and the separated mother liquor is refluxed to the carbonization tower 5-5 to separate the ammonia in the biogas slurry to obtain ammonium bicarbonate fertilizer.
[0031] See Figure 1 As shown, the ozone reactor 6 of the present invention is used to perform ozone oxidation treatment on organic matter. The ozone reactor 6 is provided with a liquid inlet at the bottom and a water outlet at the top. A small amount of organic matter in the wastewater is degraded by ozone treatment, so that the ozone effluent meets the pipe emission standard and can be discharged.
[0032] See Figure 1 、 2As shown, the organic waste resource treatment system of the present invention is used to treat agricultural organic waste. The agricultural organic waste is crushed and then added to the anaerobic reactor 1. The agricultural organic waste and anaerobic sludge are mixed and stirred by the electric stirrer 1-1. A large amount of alkalinity is generated during the anaerobic microbial metabolic reaction, which is mainly composed of bicarbonate, and can degrade most organic matter and convert organic nitrogen such as protein into ammonia nitrogen. The biogas generated by anaerobic means is sent to the steam boiler 7, and the steam generated by the steam boiler 7 is used as the steam source for the deamination tower 5-1. The anaerobic effluent enters the solid-liquid separator 2 for solid-liquid separation. The separated solid residue is used as agricultural fertilizer, and the separated liquid enters the microfiltration membrane module 4 through the water inlet pump 3 to further remove fine suspended matter. The concentrated liquid after microfiltration is returned to the anaerobic reactor 1 for further degradation, ensuring the anaerobic sludge concentration. The effluent of the microfiltration membrane module 4 first flows into the water inlet at the top of the deamination tower 5-1, and the steam enters the lower part of the deamination tower 5-1. Through the stripping effect, the ammonium bicarbonate in the biogas slurry is decomposed into ammonia, carbon dioxide, etc. and enters the gas-liquid separation tank 5-2 through the mixed gas pipe at the top of the deamination tower 5-1. The mixed gas is in the gas-liquid separation tank 5-2. After condensation in the condenser, ammonia and water vapor are condensed to form ammonia water, while gases such as carbon dioxide flow out of the gas-liquid separation tank 5-2 and are sent to the bottom of the carbonization tower 5-5. The dilute ammonia water in the gas-liquid separation tank 5-2 is concentrated and then enters the carbonization tower 5-5. In the carbonization tower 5-5, the ammonia water absorbs carbon dioxide to generate ammonium bicarbonate. The saturated ammonium bicarbonate solution formed by continuous circulation absorption enters the centrifuge 5-8 through the centrifugal feed pump 5-7, and the fine crystals in the saturated ammonium bicarbonate solution are separated. The separated mother liquor is returned to the carbonization tower 5-5, and ammonium bicarbonate fertilizer is obtained by steam stripping, deammonification and carbonization. The remaining wastewater after deamination is stored at the bottom of the deamination tower 5-1 and is sent to the ozone reactor 6 through the ozone feed pump 5-3 to perform ozone oxidation and degradation on a small amount of organic matter in the wastewater. Table 1 shows the main indicators of various water quality. Therefore, after being treated by the treatment system of the utility model, the ozone effluent can meet the piped emission standards, and can realize efficient energy utilization and full-scale treatment of organic waste.
