Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically to an integrated sewage treatment equipment. Background Technology

[0002] Wastewater treatment equipment is a general term for various devices that remove and transform pollutants in wastewater through physical, chemical, or biological technologies to purify water quality. It is widely used in various wastewater treatment scenarios.

[0003] Current wastewater treatment equipment still has the following problems when in use: 1. Existing wastewater treatment equipment, especially in the anaerobic and hydrolysis acidification stages, often employs simple mechanical or aeration mixing methods. This results in dead zones within the tank, uneven mixing of sludge and wastewater, low mass transfer efficiency, and limited microbial activity, thereby affecting overall treatment efficiency and prolonging reaction time. 2. Traditional wastewater treatment equipment is typically a modular structure, with each treatment unit set up independently, resulting in a large footprint. Furthermore, each tank requiring agitation needs its own independent drive motor, leading to complex equipment structure, high manufacturing costs, and high overall system energy consumption.

[0004] Therefore, it is necessary to propose an integrated wastewater treatment device to solve the above problems. Utility Model Content

[0005] To address the above problems, this utility model provides an integrated wastewater treatment device that improves wastewater treatment efficiency and increases gas mixing efficiency in anaerobic and hydrolysis acidification tanks.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An integrated wastewater treatment device includes a housing, in which an anaerobic tank, a hydrolysis acidification tank, a contact oxidation tank, a sedimentation tank, and a clear water tank are arranged sequentially. Each of the anaerobic tank, hydrolysis acidification tank, contact oxidation tank, and sedimentation tank is connected to an inlet pipe. A sludge return pipe is connected between the sedimentation tank and the anaerobic tank. An aeration pipe is connected to the contact oxidation tank, and an aeration head is connected to the aeration pipe. An outlet pipe located in the clear water tank is connected to the housing. Both the anaerobic tank and the hydrolysis acidification tank are internally connected to an air supply pipe and a base. One end of the air supply pipe is connected to the base, and the end of the air supply pipe away from the base is externally connected to an air supply device. A rotating disk is rotatably connected to the top of the base. A horizontally arranged moving pipe is connected inside the rotating disk. Both ends of the moving pipe have upward-facing air outlets, and a through hole is opened in the middle of the moving pipe. A gas flow channel is opened inside the air supply pipe, and the air supply pipe is connected to the through hole on the moving pipe through the gas flow channel. When the rotating disk rotates, the ejected airflow can increase the stirring effect.

[0007] Preferably, to improve the mixing effect and range, the moving tube is slidably connected to the rotating disk, and a disc is connected to the top of the base. The top of the disc has a sliding groove, which is preferably star-shaped or flower-shaped. When the first pin moves in the sliding groove, the two ends of the moving tube extend outward at different lengths, thus increasing the mixing effect. The outer wall of the moving tube is connected to the first pin located in the sliding groove. The two ends of the moving tube are at different distances from the first pin, which increases the mixing area when moving along the sliding groove.

[0008] Preferably, in order to improve the stability of the moving tube during movement, a guide groove is provided at the top of the rotating disk, the direction of the guide groove is the same as the axial direction of the moving tube, and a second pin located in the guide groove is connected to the top of the moving tube.

[0009] Preferably, in order to improve the stirring effect, a first stirring blade is connected to the outer wall of the rotating disk, and a second stirring blade is connected to both ends of the moving tube.

[0010] Preferably, in order to make the rotating disk rotate, a rotating rod is connected to the top of the rotating disk, a drive motor is connected to the housing, and the output end of the drive motor and the rotating rod are connected by a chain drive structure.

[0011] Preferably, in order to synchronize the rotation of the two rotating rods, the two adjacent rotating rods are connected by a chain drive.

[0012] Preferably, in order to improve the water purification effect, the sedimentation tank is provided with an overflow weir connected to the clear water tank at the top.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Improved treatment efficiency and mixing uniformity: Through the coordinated rotation, extension, and jetting in the anaerobic tank and hydrolysis acidification tank, especially by utilizing the star-shaped sliding trough to achieve asymmetric extension and contraction of the moving pipe, dead zones in the mixing are effectively eliminated, the mass transfer effect of the gas, liquid, and solid phases is enhanced, and the contact between microorganisms and pollutants is more sufficient, thereby improving the effect of wastewater treatment.

[0014] 2. A single drive motor simultaneously drives the stirring systems of both the anaerobic tank and the hydrolysis acidification tank via a chain transmission structure. Compared to the traditional dual-motor configuration, this simplifies the mechanical structure and reduces manufacturing costs. Furthermore, integrating multiple tanks into a single, compact housing reduces the floor space required.

[0015] 3. Through a multi-stage series process of anaerobic, hydrolytic acidification and contact oxidation, combined with the sludge return mechanism of the sedimentation tank, the system is more tolerant to fluctuations in influent water quality, which enhances system stability and improves effluent water quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In this case, the selection of materials, heat treatment processes, and structural dimensions of conventional and critical load-bearing components all conform to standards.

[0020] Please see Figure 1-8 An integrated wastewater treatment device includes a housing 101, which is an integrated structure with a compact design and small footprint. The housing 101 contains, in sequence, an anaerobic tank 102, a hydrolysis acidification tank 103, a contact oxidation tank 104, a sedimentation tank 105, and a clear water tank 106. Each of the anaerobic tank 102, hydrolysis acidification tank 103, contact oxidation tank 104, and sedimentation tank 105 is connected to an inlet pipe 107. A sludge return pipe 108 connects the sedimentation tank 105 and the anaerobic tank 102 to return the deposited sludge to the anaerobic tank 102. An aeration pipe 109 is connected to the contact oxidation tank 104, and an aeration head is connected to the aeration pipe 109 to supply oxygen to the contact oxidation tank 104. An outlet pipe 110 located within the clear water tank 106 is connected to the housing 101. The wastewater treatment method is as follows: Step 1: Anaerobic Tank 102 Treatment: Wastewater first enters anaerobic tank 102. In a completely anaerobic environment, anaerobic microorganisms decompose some easily degradable organic matter, initially breaking down complex organic matter into simple substances and producing a small amount of methane gas.

[0021] Step 2: Treatment in hydrolysis acidification tank 103: Wastewater treated in anaerobic tank 102 flows into hydrolysis acidification tank 103. In a low-oxygen environment, hydrolytic bacteria and acid-producing bacteria decompose recalcitrant macromolecular organic matter into small-molecule organic acids.

[0022] Step 3: Contact oxidation tank 104 treatment: This is the core aerobic treatment step. The tank is filled with biological packing materials, such as elastic packing materials or combined packing materials, and the aeration pipe 109 continuously supplies oxygen, allowing aerobic microorganisms to form a biofilm on the surface of the packing materials.

[0023] Step 4: Sedimentation tank 105 treatment: Wastewater flowing out of contact oxidation tank 104 enters sedimentation tank 105, where the water flow rate slows down and solid impurities and biological sludge settle naturally under gravity.

[0024] Step 5: Treatment in Clear Water Tank 106: The supernatant from sedimentation tank 105 enters clear water tank 106 for final disinfection treatment, such as ultraviolet disinfection or chlorine dioxide addition, to kill pathogenic microorganisms and ensure that the effluent meets the standards.

[0025] Each tank is connected in sequence via an inlet pipe 107. The sedimentation tank 105 has a sludge return pipe 108 at its bottom, connecting to the anaerobic tank 102 to achieve sludge recycling. An aeration pipe 109 is arranged at the bottom of the contact oxidation tank 104, providing sufficient oxygen through aeration heads. The treated clean water is discharged through the outlet pipe 110 of the clear water tank 106.

[0026] Both the anaerobic tank 102 and the hydrolysis acidification tank 103 are internally connected to an air supply pipe 111 and a base 112. The base 112 is connected to the bottom wall inside the housing 101. One end of the air supply pipe 111 is connected to the base 112, and the end of the air supply pipe 111 away from the base 112 is externally connected to an air supply device for supplying oxygen to the anaerobic tank 102 and the hydrolysis acidification tank 103. A rotating disk 113 is rotatably connected to the top of the base 112, and a horizontally arranged movable device is connected inside the rotating disk 113. The moving pipe 114 has upward-facing air outlets 115 at both ends and a through hole 116 in the middle. The air supply pipe 111 has a gas flow channel inside. An external air supply device supplies airflow sequentially through the air supply pipe 111, the air flow channel, and the through hole 116 into the moving pipe 114. The air supply pipe 111 is connected to the through hole 116 on the moving pipe 114 via the gas flow channel. When the rotating disk 113 rotates, the ejected airflow increases the stirring effect. The rotating moving pipe 114 ejects airflow, and in the anaerobic tank 102, stirring allows anaerobic microorganisms to fully mix with wastewater and returned sludge, preventing sludge settling and accumulation, and ensuring efficient decomposition of macromolecular organic matter. In the hydrolysis acidification tank 103, stirring enhances the macromolecular hydrolysis reaction, preventing wastewater stratification or sludge deposition, and resulting in more uniform organic acid production.

[0027] Specifically, to improve the mixing effect and range, the moving tube 114 is slidably connected to the rotating disk 113. A disc 117 is connected to the top of the base 112, and a sliding groove 118 is formed on the top of the disc 117. The sliding groove 118 is preferably star-shaped or flower-shaped. When the first pin 119 moves within the sliding groove 118, the two ends of the moving tube 114 extend outwards at different lengths, increasing the mixing effect. The first pin 119, located within the sliding groove 118, is connected to the outer wall of the moving tube 114. The different distances between the two ends of the moving tube 114 and the first pin 119 increase the mixing area as it moves along the sliding groove 118. Airflow is ejected from one end towards a distance, and from the other end towards a closer location.

[0028] Specifically, to improve the stability of the moving tube 114 during movement, a guide groove 120 is provided at the top of the rotating disk 113. The direction of the guide groove 120 is the same as the axial direction of the moving tube 114, which is used to stabilize the axial movement of the moving tube 114. A second pin 121 located in the guide groove 120 is connected to the top of the moving tube 114.

[0029] Specifically, in order to improve the stirring effect, a first stirring blade 122 is connected to the outer wall of the rotating disk 113, and a second stirring blade 123 is connected to both ends of the moving tube 114 to increase the stirring area.

[0030] Specifically, in order to rotate the rotating disk 113, a rotating rod 124 is connected to the top of the rotating disk 113, and a drive motor 125 is connected to the housing 101. The output end of the drive motor 125 and the rotating rod 124 are connected through a chain drive structure 126. The chain drive structure 126 consists of a chain and a sprocket, which is a mature existing structure and will not be described in detail here.

[0031] Specifically, in order to synchronize the rotation of the two rotating rods 124, the two adjacent rotating rods 124 are connected by a chain drive to keep the two rotating rods 124 rotating synchronously.

[0032] Specifically, in order to improve the water purification effect, the upper part of the sedimentation tank 105 is provided with an overflow weir or outlet trough connected to the clear water tank 106, so that the upper water in the sedimentation tank 105 will flow into the clear water tank 106.

[0033] The stirring method is as follows: The drive motor 125 drives the rotating rod 124 to rotate through the chain transmission structure 126. The rotating rod 124 drives the internal moving tube 114 to rotate through the rotating disk 113. When rotating, the moving tube 114 slides in the sliding groove 118 through the first pin 119, thereby sliding back and forth on the rotating disk 113, which increases the diffusion area of ​​the ejected gas.

[0034] The first stirring blade 122 and the second stirring blade 123 on the outer wall are used to increase the stirring area.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
