Description

Technical Field

[0001] This application relates to the technical field of multi-source organic waste treatment, and in particular to a multi-source organic waste synergistic conversion wastewater treatment composite carbon source system. Background Technology

[0002] The efficiency of nitrogen removal processes in wastewater treatment is becoming increasingly important. Nitrifying microorganisms require sufficient and balanced nutrients for denitrification, and carbon sources are a key factor. A suitable carbon source can provide adequate nutrition for denitrifying microorganisms, promoting their growth and metabolism, thereby effectively improving denitrification efficiency. However, traditional external carbon sources such as methanol, sodium acetate, and glucose are costly, and a single carbon source cannot meet the comprehensive nutritional needs of denitrifying microorganisms. Meanwhile, large amounts of organic waste, such as the three-phase centrifugal waste liquid generated in the aerobic composting process of kitchen waste, waste pulp from the processing of dried tangerine peel, byproducts of biodiesel production, and polysaccharide byproducts from the processing of traditional Chinese medicine, will not only waste resources but also cause environmental pollution if not effectively utilized. If these organic wastes can be converted into composite carbon sources that can be used for wastewater treatment, it can solve environmental problems and reduce wastewater treatment costs, resulting in significant economic and environmental benefits.

[0003] In terms of organic waste treatment, current methods for handling organic waste such as kitchen waste, dried tangerine peel pulp, alcohol byproducts from biodiesel production from kitchen waste oil, and polysaccharide byproducts from alcohol extraction processes in traditional Chinese medicine factories have many shortcomings. The three-phase centrifugal wastewater generated during the aerobic composting process of kitchen waste is directly treated as high-concentration organic wastewater for purification. This wastewater treatment process is complex, with high engineering costs and operating expenses, severely impacting the profitability of kitchen waste treatment projects. Dried tangerine peel pulp is mostly discarded directly, resulting in resource waste, and its decomposition in the natural environment may cause odor and environmental pollution problems. Crude glycerol has many impurities, limiting its subsequent utilization; it generally requires a complex and costly refining process before it can be used in other industrial fields. Polysaccharide byproducts from alcohol extraction of traditional Chinese medicine are usually treated as waste, not effectively utilized, and their rich nutrients are wasted.

[0004] Therefore, given the problems with traditional carbon source applications and organic waste treatment, it is of great practical significance to develop a system that can effectively utilize organic waste and provide a high-quality composite carbon source for denitrification in wastewater treatment.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a multi-source organic waste synergistic conversion wastewater treatment composite carbon source system, referring to... Figure 1 In this embodiment, the system includes a food waste pretreatment device 1, a waste fruit pulp pretreatment device 3, an alcohol by-product pretreatment device 4, a polysaccharide by-product pretreatment device 5, a stirring sterilization treatment device 6, and a collection and storage device 8.

[0028] Among them, the kitchen waste pretreatment device 1 can process the collected kitchen waste to obtain the liquid phase of the kitchen waste three-phase centrifuge; the waste fruit pulp pretreatment device 3 can process the waste fruit pulp obtained from the tangerine peel production and processing plant to obtain tangerine peel waste fruit pulp juice; the alcohol by-product pretreatment device 4 can obtain alcohol by-products from the production of biodiesel from kitchen waste oil; and the polysaccharide by-product pretreatment device 5 can obtain polysaccharide by-products from the alcohol extraction process of traditional Chinese medicine factories.

[0029] Meanwhile, the food waste pretreatment device 1, the waste fruit pulp pretreatment device 3, the alcohol by-product pretreatment device 4, and the polysaccharide by-product pretreatment device 5 are respectively coordinated with the stirring and sterilization treatment device 6 to add the pretreated food waste three-phase centrifuge liquid phase, the juice of pressed tangerine peel pulp, the alcohol by-products of biodiesel made from food waste oil, and the polysaccharide by-products of the alcohol extraction process of traditional Chinese medicine factories into the stirring and sterilization treatment device 6 for thorough stirring and sterilization, thereby producing a composite carbon source product.

[0030] In addition, the collection and storage device 8 is located on one side of the stirring sterilization treatment device 6, and the input end of the collection and storage device 8 is matched with the output end of the stirring sterilization treatment device 6 so as to seal and store the above-prepared composite carbon source product in the collection and storage device 8.

[0031] Therefore, this application, through the coordinated system of a kitchen waste pretreatment device 1, a waste fruit pulp pretreatment device 3, an alcohol by-product pretreatment device 4, a polysaccharide by-product pretreatment device 5, a stirring sterilization treatment device 6, and a collection and storage device 8, can rationally treat and compound various organic wastes into composite carbon sources, balancing the nutrients required by denitrifying microorganisms in wastewater treatment, thereby reducing wastewater treatment costs and improving denitrification efficiency; at the same time, it realizes the resource recovery and reuse of organic waste, thereby reducing the production cost of composite carbon sources, and thus meeting the urgent need of the wastewater treatment industry for efficient and low-cost carbon sources.

[0032] The following is a detailed description of the structure of the food waste pretreatment device 1, the waste fruit pulp pretreatment device 3, the alcohol by-product pretreatment device 4, the polysaccharide by-product pretreatment device 5, the stirring sterilization treatment device 6, and the collection and storage device 8:

[0033] Specifically, refer to Figure 1 In this embodiment, the food waste pretreatment device 1 includes a sorting and impurity removal machine 11, a pulping machine 12, a sand remover 13, a three-phase centrifuge 14, and a three-phase centrifuge liquid phase collection tank 15. The sorting and impurity removal machine 11, the pulping machine 12, the sand remover 13, the three-phase centrifuge 14, and the three-phase centrifuge liquid phase collection tank 15 cooperate with each other. More specifically, the sorting and impurity removal machine 11 can sort and remove impurities from the collected food waste, removing large impurities such as plastics and metals.

[0034] The pulping machine 12 is installed on one side of the sorting and impurity removal machine 11. The sorted and impurity-removed kitchen waste is then added to the pulping machine 12 for pulping, thus breaking the kitchen waste into a uniform slurry. Simultaneously, the input end of the pulping machine 12 is connected to an external high-temperature steam supply device 2 via a steam conveying pipe 21. This allows the external high-temperature steam supply device 2 to deliver high-temperature steam along the steam conveying pipe 21 into the pulping machine 12, uniformly heating and cooking the slurry inside, thereby ensuring the material is fully cooked and allowing the animal and vegetable oils in the material to be fully extracted. It should be noted that the high-temperature steam supply device 2 is existing equipment and will not be described in detail here.

[0035] The desander 13 is installed on one side of the pulper 12. The heated and cooked pulp is then added to the desander 13 for desanding to remove inorganic impurities such as sand particles. The three-phase centrifuge 14 is installed on one side of the desander 13. The desanded pulp is then added to the three-phase centrifuge 14 for oil extraction to separate the oil and obtain the liquid phase of the three-phase centrifuge.

[0036] In addition, the three-phase centrifuge liquid phase collection tank 15 is installed on one side of the three-phase centrifuge 14, and an anaerobic fermentation tank 16 is also installed between the three-phase centrifuge liquid phase collection tank 15 and the three-phase centrifuge 14. The three-phase centrifuge liquid phase obtained above and the pre-enriched and domesticated acid-producing microorganisms are added to the anaerobic fermentation tank 16 respectively. Anaerobic fermentation is used to hydrolyze and produce organic acids and organic alcohols. During the anaerobic fermentation process, the fermentation temperature is controlled and the mixture is stirred regularly to ensure that the acid-producing microorganisms are in close contact with the three-phase centrifuge liquid phase of the kitchen waste.

[0037] After 5-7 days of continuous anaerobic fermentation, the hydrolysate is filtered using a microfiltration membrane to remove any remaining fine solid impurities. The filtered three-phase centrifuge liquid phase is then collected and stored in a three-phase centrifuge liquid phase collection tank 15 for later use in the preparation of the composite carbon source product. Specifically, the sorting and impurity removal machine 11, pulping machine 12, sand remover 13, three-phase centrifuge 14, anaerobic fermentation tank 16, and three-phase centrifuge liquid phase collection tank 15 are all existing equipment and will not be described in detail here.

[0038] Specifically, refer to Figure 1 In this embodiment, the waste fruit pulp pretreatment device 3 includes a press 31, a juice collection tank 32 installed at the output end of the press 31, a juice centrifuge 33 installed on one side of the press 31, and a supernatant collection tank 34 installed on one side of the juice centrifuge 33. Waste fruit pulp obtained from the tangerine peel production and processing plant is put into the press 31, which then presses the waste fruit pulp to obtain juice, which is collected in the juice collection tank 32.

[0039] Next, pectinase is added to the juice collection tank 32 for enzymatic hydrolysis. The hydrolyzed juice is then added to the juice centrifuge 33 for centrifugation to remove precipitates and impurities and collect the supernatant. The collected supernatant is stored in the supernatant collection tank 34 for use in the preparation of the composite carbon source product. Specifically, the press 31, juice collection tank 32, juice centrifuge 33, and supernatant collection tank 34 are all existing equipment and will not be described in detail here.

[0040] Specifically, refer to Figure 1 In this embodiment, the alcohol by-product pretreatment device 4 includes a vacuum distillation unit 41 and an alcohol by-product collection tank 42 placed on one side of the vacuum distillation unit 41. By adding the alcohol by-products from the production of biodiesel from kitchen waste oil to the vacuum distillation unit 41 for vacuum distillation, water and a small amount of residual fatty acid methyl esters and other impurities can be removed. The treated alcohol by-products are then collected in the alcohol by-product collection tank 42 for use in the preparation of the composite carbon source product. Specifically, both the vacuum distillation unit 41 and the alcohol by-product collection tank 42 are existing equipment and will not be described in detail here.

[0041] Specifically, refer to Figure 1 In this embodiment, the polysaccharide by-product pretreatment device 5 includes a polysaccharide by-product collection tank 51. Polysaccharide by-products can be obtained through the alcohol extraction process in a traditional Chinese medicine factory. The main component of these by-products is polysaccharides. These polysaccharides are collected and stored in the polysaccharide by-product collection tank 51, and can be directly used as raw materials for compounding composite carbon sources when preparing the final composite carbon source product. Specifically, the polysaccharide by-product collection tank 51 is existing equipment and will not be described in detail here.

[0042] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the stirring sterilization treatment device 6 includes a stirring tank 61, a stirrer 62, and a high-temperature sterilization mechanism. The stirrer 62 is installed inside the stirring tank 61 and can mix the materials inside the stirring tank 61 evenly. The stirring tank 61 also works in conjunction with the three-phase centrifuge liquid phase collection tank 15, the supernatant collection tank 34, the alcohol by-product collection tank 42, and the polysaccharide by-product collection tank 51. This allows for the addition of pretreated kitchen waste from the three-phase centrifuge, juice from pressed tangerine peel pulp, alcohol by-products from the biodiesel production process from kitchen waste oil, and polysaccharide by-products from the alcohol extraction process in traditional Chinese medicine factories to the stirring tank 61 for thorough mixing, thereby obtaining a mixed solution.

[0043] Meanwhile, in this embodiment, the high-temperature sterilization mechanism is located on one side of the mixing tank 61, and the high-temperature sterilization mechanism cooperates with the mixing tank 61 to sterilize the mixed liquid in the mixing tank 61 by means of high-temperature instantaneous sterilization. After sterilization, the composite carbon source product can be obtained.

[0044] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the high-temperature sterilization mechanism includes steam nozzles 63, steam delivery hoses 64, a support plate 65, a locking assembly, a steam delivery ring pipe 7, a steam output pipe 71, a connecting assembly, and a steam input pipe 72. Several steam nozzles 63 are provided, evenly installed on the inner walls of the mixing tank 61. Several steam delivery hoses 64 are provided, one end of each hose being connected to the input end of the steam nozzle 63, and the other end extending outside the mixing tank 61.

[0045] Furthermore, there are two support plates 65, both of which are symmetrically installed on the outer wall of the mixing tank 61 by locking components; the steam conveying ring is placed on the two support plates 65, so that the two support plates 65 support the steam conveying ring pipe 7; there are several steam output pipes 71, one end of each of the steam output pipes 71 is connected to the inner side of the steam conveying ring pipe 7, and the other end of each of the steam output pipes 71 is fixedly connected to the end of each of the steam conveying hoses 64 away from the steam nozzle 63 by connecting components; one end of the steam input pipe 72 is fixedly connected to one side of the steam conveying ring pipe 7, and the other end of the steam input pipe 72 is connected to the output end of the external high-temperature steam supply equipment 2.

[0046] When the mixture in the mixing tank 61 needs to be sterilized, high-temperature steam is delivered to the steam delivery ring pipe 7 through the external high-temperature steam supply device 2 along the steam input pipe 72. Then, the high-temperature steam is delivered to the steam delivery hose 64 from the steam output pipe 71. Finally, the high-temperature steam is sprayed into the interior of the mixing tank 61 from the steam nozzle 63 to perform high-temperature sterilization of the mixture.

[0047] The structure of the locking assembly and the connecting assembly is described in detail below:

[0048] Specifically, refer to Figure 2 and Figure 3In this embodiment, the locking assembly includes a locking plate 651, a rotating shaft, and locking blocks 66. The locking plate 651 is vertically mounted on one side of the support plate 65, and a locking groove 67 is formed on the outer wall of the mixing tank 61. The locking groove 67 cooperates with the locking plate 651, causing the locking plate 651 to abut against the locking groove 67. Two rotating shafts are provided, symmetrically mounted on the outer wall of the mixing tank 61, and located on the upper and lower sides of the locking groove 67, respectively. Two locking blocks 66 are provided, each mounted on one of the two rotating shafts.

[0049] When the locking plate 651 is abutted in the locking groove 67, the locking block 66 on the rotating shaft is rotated so that the locking block 66 abuts against the side of the locking plate 651 facing the bearing plate 65, thereby securing the locking plate 651 in the locking groove 67 and thus achieving a stable installation of the bearing plate 65.

[0050] Specifically, refer to Figure 3 and Figure 4 In this embodiment, the connecting assembly includes a limiting ring 641, a connecting sleeve 642, and a sealing ring 68. The limiting ring 641 is installed on the outer side of the end of the steam delivery hose 64 furthest from the steam nozzle 63. The connecting sleeve 642 is movably fitted onto the outer side of the steam delivery hose 64, and the inner side of the connecting sleeve 642 cooperates with the limiting ring 641, allowing the limiting ring 641 to block the connecting sleeve 642, thereby preventing the connecting sleeve 642 from detaching from the outside of the steam delivery hose 64.

[0051] Meanwhile, the inner side of the connecting sleeve 642 is provided with an internal thread, and the outer side of the end of the steam output pipe 71 away from the steam conveying ring pipe 7 is provided with an external thread. The external thread and the internal thread are threaded together, so that the connecting sleeve 642 can be screwed into the outer side of the steam output pipe 71, so that the limiting ring 641 on the steam conveying hose 64 is pressed against the opening of the steam output pipe 71, so as to realize the interconnection between the steam conveying hose 64 and the steam output pipe 71.

[0052] In addition, the sealing ring 68 is installed on the outside of the ring opening of the limiting ring 641. When the limiting ring 641 is pressed against the opening of the steam output pipe 71, the sealing ring 68 and the opening of the steam output pipe 71 are pressed against each other, so that the steam delivery hose 64 and the steam output pipe 71 can be more tightly connected, thereby preventing steam leakage.

[0053] Preferably, in this embodiment, an insulation layer is securely fitted on the outside of the steam delivery hose 64, the steam delivery ring pipe 7, the steam output pipe 71, the steam input pipe 72, and the steam delivery pipe 21. The insulation layer is insulation cotton, which can effectively insulate these pipes.

[0054] Secondly, specifically, refer to Figure 1 and Figure 2 In this embodiment, the collection and storage device 8 includes a collection and storage tank 81, an inlet 82, an outlet 69, and an automatic conveying component. The collection and storage tank 81 is installed on one side of the mixing tank 61; the inlet 82 is installed at the inlet end of the top of the collection and storage tank 81; the outlet 69 is installed at the outlet end of the bottom of the mixing tank 61, and a valve is also installed on the outlet 69; the automatic conveying component is a screw conveyor 83, which is installed between the mixing tank 61 and the collection and storage tank 81, with its inlet end fixedly connected to the outlet 69 and its outlet end fixedly connected to the inlet 82.

[0055] When the valve is opened and the screw conveyor 83 is started, the composite carbon source product prepared in the mixing tank 61 enters the screw conveyor 83 through the output port 69. Then, under the conveying action of the screw conveyor 83, the composite carbon source product is transported to the input port 82, and finally discharged into the collection and storage tank 81 for sealed storage at room temperature. It should be noted that this screw conveyor 83 is existing equipment and will not be described in detail here.
