Description

[0002] With the rapid development of industrialization and urbanization, the amount of wastewater generated has increased dramatically, making wastewater treatment a key aspect of environmental protection.

[0003] Traditional wastewater treatment systems suffer from high energy consumption, low treatment efficiency, and secondary pollution. Meanwhile, the energy crisis is increasingly prominent, making the search for renewable and clean energy sources for wastewater treatment a growing industry trend. Solar energy, as an inexhaustible clean energy source, and bioenergy generated during wastewater treatment (such as biogas), if effectively integrated and utilized, will bring new breakthroughs to wastewater treatment. However, existing wastewater treatment systems have technical shortcomings in areas such as the synergistic utilization of solar and bioenergy, and the recycling of biological carrier particles during anaerobic biological treatment. For example, the mixing reaction of anaerobic organisms with wastewater is inefficient and energy-intensive, making it difficult to achieve efficient and sustainable wastewater treatment. Therefore, this paper proposes a wastewater treatment system integrating solar and bioenergy. Summary of the Invention

[0013] Furthermore, the one-way sealing mechanism includes an inner ring and an outer ring. The inner ring is fixed to the top of the partition by a bolt structure. Several elastic plates are evenly fixed between the inner ring and the outer ring at equal angles. A sealing gasket matching the upper port is fixed to the bottom of the outer ring.

[0014] Furthermore, the partition is also equipped with an anaerobic silo, the discharge port of the anaerobic silo is connected to the middle of the sewage pipe, and the inlet of the anaerobic silo is located on the side close to the anaerobic conveying pipe.

[0015] The partition is fixed with sealing inner rings on both the upper and lower sides of the feed inlet. The sealing inner rings abut against the outer wall of the anaerobic conveying pipe.

[0048] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0049] Example:

[0050] This invention provides a wastewater treatment system integrating solar and bioenergy. Please refer to [link / reference]. Figure 1 - Figure 13 The core of the system consists of a multi-stage pretreatment tank 1 and an anaerobic biological reactor 2. The multi-stage pretreatment tank 1 plays a key role in the pretreatment of wastewater in the multi-stage wastewater treatment process. Wastewater first enters the multi-stage pretreatment tank, where larger suspended solids and debris are removed by a screen to prevent them from clogging subsequent treatment equipment. Then it enters the grit chamber, where the principle of gravity sedimentation is used to remove inorganic particles such as sand from the wastewater. In the equalization tank, the water quality and quantity of the wastewater are balanced to ensure the stable operation of the subsequent anaerobic biological reactor 2.

[0051] Please see Figure 4 The bottom of the anaerobic biological reactor 2 is equipped with a sewage delivery pipe 25. The multi-stage pretreatment tank 1 puts the pretreated sewage into the anaerobic biological reactor 2 through the sewage delivery pipe 25. A one-way valve 251 is installed in the sewage delivery pipe 25.

[0052] Please see Figure 3The top of the anaerobic bioreactor 2 is equipped with a three-phase separator 22, whose main function is to efficiently separate the gas, liquid and solid phases. In this application, the main separated substances are biogas, sewage and biomass packing material. The biomass packing material is composed of anaerobic biological carrier particles as the packing medium. Microorganisms continuously gather and multiply on the surface of the packing medium, gradually forming granular substances. The biogas separated by the three-phase separator 22 is transported to the biogas collection device through pipeline and the heat energy generated by the biogas combustion is converted into electrical energy that can be stored in the storage battery 4 by the biogas internal combustion generator, realizing the efficient utilization of bioenergy. The solid separated by the three-phase separator 22 is transported to the filter mechanism 5 through pipeline and then transported to the anaerobic conveying pipe 7 after being processed by the filter mechanism 5. The sewage separated by the three-phase separator 22 enters the next stage of treatment equipment.

[0053] Please see Figure 3-11 At the bottom of the anaerobic bioreactor 2, a mixing mechanism 6 is installed on one side, and an anaerobic conveying pipe 7 for feeding anaerobic biological carrier particles is installed on the other. The mixing mechanism 6 can reciprocate up and down under the strong drive of the drive mechanism, so as to fully mix the anaerobic biological carrier particles with the sewage. On one side of the outer wall of the anaerobic bioreactor 2, a filtration mechanism 5 is installed. Its function is to filter the solids separated by the three-phase separator 22, which contain anaerobic biological carrier particles, and to transport the treated particles back to the anaerobic conveying pipe 7. In addition, the anaerobic bioreactor 2 is also equipped with a solar photovoltaic panel 3 and a battery 4. The solar photovoltaic panel 3 is electrically connected to the battery 4 through an inverter, thereby providing stable power to some equipment in the system, including heating the spiral electric heating tube in the compartment 23. The temperature inside the anaerobic bioreactor 2 can be precisely adjusted according to actual needs to create the most suitable living environment for anaerobic microorganisms.

[0054] Please see Figure 3-11 The mixing mechanism 6 includes a partition 61, and a sealing piston ring 64 is rotatably connected to the circumferential side of the partition 61. The partition 61 of the mixing mechanism 6 is in close contact with the inner wall of the bottom of the anaerobic bioreactor 2 through the sealing piston ring 64, thereby ensuring the sliding seal between the partition 61 and the inner wall of the anaerobic bioreactor 2. Pretreated sewage can be transported to the bottom of the partition 61 through the sewage conveying pipe 25. The pumped water pressure is used to lift the partition 61 to the highest position for use.

[0055] Please see Figure 6-7 The bottom of the partition 61 is provided with a number of mixing blades 612, and the partition 61 is provided with a number of sewage pipes 67 corresponding to the number of mixing blades 612. The lower port 672 of the sewage pipe 67 is provided on the end face of the mixing blades 612, and the upper port 671 of the sewage pipe 67 is provided on the top side of the partition 61.

[0056] Please see Figure 6 and Figure 8 The top of the partition 61 is also fixed with a one-way sealing mechanism 62. The one-way sealing mechanism 62 is used to block the upper port 671 of the sewage pipe 67 during the upward movement of the partition 61 and to open the upper port 671 of the sewage pipe 67 when the partition 61 moves downward. Specifically, the one-way sealing mechanism 62 includes an inner ring 621 and an outer ring 623. The outer edge of the outer ring 623 is fixed with a ceramic wear-resistant layer. The inner ring 621 is fixed to the top of the partition 61 by bolts. Several elastic plates 622 are evenly fixed between the inner ring 621 and the outer ring 623 at equal angles. The bottom of the outer ring 623 is fixed with a sealing gasket 624 that matches the upper port 671. The elastic plates 622 have an elastic force that drives the outer ring 623 to approach the upper port 671.

[0057] When the baffle 61 moves upward under the action of the bottom water pressure, the outer ring 623 uses the friction with the inner wall of the anaerobic biological reactor 2 and the elasticity of the elastic plate 622 to keep the sealing gasket 624 sealed on the upper port 671, thus maintaining the sealing of the sewage pipe 67 during the upward movement of the baffle 61.

[0058] Please see Figure 9 and Figure 4 The top of the anaerobic conveying pipe 7 is provided with a spiral groove 71, and the bottom of the partition 61 is provided with a nut seat 65 that matches the spiral groove 71. The nut seat 65 is unidirectionally connected to the bottom of the partition 61 through a ratchet mechanism. In order to maintain the sealing between the nut seat 65 and the anaerobic conveying pipe 7 during the displacement process, an elastic sealing membrane 9 is fixed at the bottom of the nut seat 65. The bottom end of the elastic sealing membrane 9 is rotatably connected to one side of the outer wall of the anaerobic conveying pipe 7.

[0059] The top inner side of the anaerobic conveying pipe 7 is also equipped with a conveying rod 8, which is specifically used to assist in the conveying of anaerobic biological carrier particles.

[0060] Specifically, the partition 61 is also equipped with an anaerobic silo 66. The discharge port 662 of the anaerobic silo 66 is connected to the middle of the sewage pipe 67, and the feed port 661 of the anaerobic silo 66 is located on the side close to the anaerobic conveying pipe 7.

[0061] The partition 61 has sealing inner rings 611 fixed on both the upper and lower sides of the feed inlet 661. The sealing inner rings 611 abut against the outer wall of the anaerobic conveying pipe 7. The top of the anaerobic conveying pipe 7 is also provided with an end cap 72. A tension spring 721 is fixed between the end cap 72 and the top of the anaerobic conveying pipe 7. The bottom of the conveying rod 8 is provided with a spiral blade 81. The top of the conveying rod 8 is rotatably connected to the middle of the end cap 72. The outer circumference of the end cap 72 is also provided with an execution skirt 722 that cooperates with the sealing inner ring 611. A pressure sensor is also fixed at the bottom of the execution skirt 722. The top inner side of the partition 61 is also fixed with a drive shaft 68. The drive shaft 68 is slidably sleeved on the top of the conveying rod 8. The bottom of the drive shaft 68 is also fixed with a second magnetic coupler 681.

[0062] The driving mechanism includes a drive motor 21 fixed to the top of the anaerobic bioreactor 2. The drive motor 21 is driven by electrical energy provided by the battery 4. The output end of the drive motor 21 is fixed with a drive rod 24 that extends into the interior of the anaerobic bioreactor 2. The outer wall of the drive rod 24 is also fixed with stirring blades 241, which are used to stir the sewage located on top of the partition 61 in the anaerobic bioreactor 2, thereby improving the efficiency of anaerobic microorganisms in decomposing organic matter in wastewater and converting it into biogas and carbon dioxide.

[0063] The bottom of the drive rod 24 is provided with a relay shaft 63, the top of the relay shaft 63 is provided with a limiting slider 632, the bottom of the drive rod 24 is provided with a vertical limiting groove 242 corresponding to the limiting slider 632, and a 243 is clamped between the limiting slider 632 and the vertical limiting groove 242. The bottom of the relay shaft 63 is rotatably connected to the top of the partition 61. The bottom of the relay shaft 63 is also provided with a first magnetic coupler 631. It should be noted that in this application, the magnetic components of the first magnetic coupler 631 and the second magnetic coupler 681 are both electromagnetic structures, and the opening and closing states of the first magnetic coupler 631 and the second magnetic coupler 681 can be electrically controlled.

[0064] Please see Figure 1 - Figure 13 The specific operation process is as follows:

[0065] Wastewater pretreatment: Wastewater first flows into multi-stage pretreatment tank 1. In multi-stage pretreatment tank 1, larger particles of impurities are removed through the effective interception of the screen, completing the preliminary purification work. After preliminary purification, the wastewater smoothly enters anaerobic biological reactor 2 under the guidance of sewage delivery pipe 25 and one-way valve 251.

[0066] Inside the anaerobic biological reactor 2, when the sewage water pressure from the sewage conveying pipe 25 lifts the baffle 61 to the design height, the sealing inner ring 611 at the top abuts against the execution skirt 722 of the end cover 72, thereby causing the end cover 72 to overcome the elastic force of the tension spring 721 and move upward, so that the top of the anaerobic conveying pipe 7 is open.

[0067] Please refer to this first. Figure 12Simultaneously, due to the pressure sensor installed on the skirt 722, the drive motor 21, the first magnetic coupler 631, and the second magnetic coupler 681 are all activated. The activation of the first magnetic coupler 631 transmits power from the drive rod 24 to the relay shaft 63, and the activation of the second magnetic coupler 681 transmits power from the relay shaft 63 to the conveying rod 8. At this time, the forward rotation of the conveying rod 8 and the spiral blade 81 causes the anaerobic biological carrier particles in the anaerobic conveying pipe 7 to be conveyed into the anaerobic silo 66 through the feed inlet 661. At the same time, the forward rotation of the partition 61 causes the anaerobic biological carrier particles in the anaerobic silo 66 to be conveyed into the anaerobic silo 66. The carrier particles enter the sewage pipe 67 through the discharge port 662 by centrifugal force. Since the upper port 671 is blocked by the one-way sealing mechanism 62, the anaerobic biological carrier particles are discharged to the bottom of the baffle 61 through the lower port 672 and mix with the sewage. As the anaerobic biological carrier particles fall from above, they are mixed evenly with the rotation of the mixing blades 612. It should be noted that during the forward rotation of the baffle 61, the mixing blades 612 rotate in the direction away from the lower port 672. At the same time, the nut seat 65 rotates freely at the bottom of the baffle 61 through the ratchet mechanism and does not cooperate with the spiral groove 71.

[0068] Please refer to this first. Figure 13 When the mixing time reaches the design value, the drive motor 21 rotates in the reverse direction, causing the partition 61 to rotate in the reverse direction. At this time, the nut seat 65 restricts the rotation of the partition 61 relative to the ratchet mechanism and engages with the spiral groove 71. Under the guidance of the spiral groove 71, the partition 61 begins to rotate and move downward. During this process, because the sewage conveying pipe 25 is equipped with a one-way valve 251, the sewage at the bottom of the partition 61 will not be discharged in the reverse direction through the sewage conveying pipe 25. As the sealing inner ring 611 moves downward with the partition 61, the end cover 72 utilizes the spring tension spring 721 to... The force moves downward and closes the upper end of the anaerobic conveying pipe 7 to prevent sewage from mixing into the anaerobic conveying pipe 7. At the same time, the one-way sealing mechanism 62 is subjected to the upward frictional force of the anaerobic biological reactor 2, causing the upper port 671 to be open. During the reverse rotation of the baffle 61, the mixing blade 612 rotates towards the side closer to the lower port 672, which on the one hand enhances the mixing effect, and on the other hand discharges the sewage with anaerobic biological carrier particles uniformly mixed through the sewage pipe 67 to the top of the anaerobic biological reactor until the baffle 61 moves down to the lowest point to start the next cycle.

[0069] The anaerobic digester 2, after undergoing anaerobic reaction, sends the resulting liquid mixture into a three-phase separator 22. Under the efficient operation of the separator, biogas, solids, and treated wastewater are successfully separated. The separated biogas is transported through a dedicated pipeline to a biogas collection device. Inside the collection device, a biogas internal combustion generator converts the heat energy from biogas combustion into electrical energy, which is stored in a battery 4. The separated solids, containing anaerobic biological carrier particles, enter a filtration mechanism 5. After filtration by this mechanism, the solids are reintroduced into the anaerobic digester 2 via an anaerobic delivery pipe 7 to continue participating in subsequent treatment processes. The treated wastewater then enters the next stage of treatment equipment for further processing.

[0070] Energy Supply and Regulation: Solar photovoltaic panels 3 continuously collect solar energy and efficiently convert it into electrical energy, which is stored in battery 4. During system operation, battery 4 provides stable power to drive motor 21, spiral heating tube, and other equipment according to the actual operating needs of the system. The spiral heating tube precisely regulates the temperature inside the anaerobic bioreactor 2 according to a preset temperature, ensuring that the activity of anaerobic microorganisms is always at its optimal state.

[0071] This invention integrates solar and bioenergy, which can reduce dependence on external power grids, lower operating costs, and achieve energy recycling, in line with the concept of sustainable development. The mixing mechanism 6 works closely with the drive mechanism to ensure that the anaerobic biological carrier particles are fully mixed with the sewage, thereby improving the efficiency of anaerobic biological reaction and thus enhancing the wastewater treatment effect.

[0072] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
