Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater microbial treatment device. Background Technology

[0002] Wastewater microbial treatment devices are environmentally friendly equipment that utilizes the metabolic activity of microorganisms to decompose, transform, and remove pollutants such as organic matter, nitrogen, and phosphorus from wastewater. They are widely used in urban wastewater treatment, industrial wastewater treatment, and rural domestic sewage treatment.

[0003] A Chinese patent (CN205099475U) discloses a microbial wastewater treatment device, comprising an outer cylinder and an inner cylinder. The inner cylinder contains a biological packing chamber. An annular float is fixed to the outer wall of the outer cylinder. A rainproof cover is installed on the upper part of the outer cylinder, forming an equipment fixing chamber between the rainproof cover and the top of the chamber. The equipment fixing chamber houses a water pump, a water pump, a controller, a sewage pump, and an air pump. Water pumps one and two are connected to the inlet and outlet pipes, respectively. The air pump is connected to an air inlet pipe. A bubble guiding device and a temperature sensor are installed inside the biological packing chamber. A heater is located at the bottom of the biological packing chamber. The controller is connected to the heater and the temperature sensor. The microorganisms cultivated by this invention are more resistant to polluted water, thus resisting and eliminating pollutants in the water and avoiding secondary pollution of the water by foreign bacteria. The cultivation environment is more suitable, and the cultivation speed is faster, thereby improving the speed of wastewater treatment.

[0004] The above-mentioned technical solution increases the oxygen content inside the treated air by using an air pump, thereby increasing the activity of aerobic microorganisms inside the treatment space and promoting the treatment of wastewater by microorganisms. However, this method can only accommodate a small amount of microorganisms, and the installation and replacement of the biological packing chamber is relatively cumbersome, resulting in a relatively slow wastewater treatment speed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a wastewater microbial treatment device, comprising: a semi-circular shell 2 and an aerobic microbial packing plate 9. The top of the semi-circular shell 2 is surrounded by baffles 3. The semi-circular shell 2 serves as a treatment chamber; its semi-circular design reduces wastewater dead zones. The baffles 3 surround the top of the shell to prevent wastewater splashing and also serve as a fixed base for subsequent wastewater pipe supports. A main shaft 8 is located between the two ends of the semi-circular shell 2. Fixing plates 14 are fixed to the outer walls of both sides of the main shaft 8. The aerobic microbial packing plate 9 is located between the fixing plates 14. The main shaft 8 passes through both ends of the shell and is fixed by bearings, serving as the rotation core. The fixing plates 14 on both sides are disc-shaped with six evenly distributed U-shaped grooves for installing the packing plate.

[0026] There are multiple aerobic microbial packing plates 9, which are evenly arranged circumferentially on the fixed plate 14. The surface of the aerobic microbial packing plates 9 is porous to provide an attachment space for microorganisms, and their two ends are embedded in the U-shaped grooves of the fixed plate.

[0027] The aerobic microbial packing plate 9 has triangular blocks 15 at both ends and bottom. Positioning shells 16 are located on the outer wall of the fixing plate 14 on both sides of the top of the triangular blocks 15. A spring 17 is located on the inner wall of one end of each positioning shell 16, and a positioning rod 18 is located at one end of each spring 17. The triangular blocks 15 are inverted triangles, and one end of the positioning rod 18 can abut against the top plane of the triangular blocks 15. The triangular blocks 15 are located at both ends and bottom of the packing plate, and their inverted triangular design forms a sloping guide. The positioning shells 16 are fixed to the outer wall of the fixing plate, and the positioning rod 18 is connected internally via the spring 17. When the packing plate is pressed into the U-shaped groove, the sloping surface of the triangular blocks 15 presses against the positioning rod 18, causing it to retract. After reaching the correct position, the positioning rod 18 pops out under the elastic force of the spring 17, abutting against the top plane of the triangular blocks to achieve axial positioning. The packing plate can be quickly installed and replaced without tools, reducing the operation time for a single person to less than 5 minutes, significantly improving maintenance efficiency.

[0028] Sewage pipe supports 4 are provided on both sides of the top of the baffle 3. A sewage branch pipe 5 is fixed to the top of the sewage pipe support 4. A main sewage pipe 6 is provided at one end of the sewage branch pipe 5, and an outlet 7 is provided at the bottom of the sewage branch pipe 5. There are multiple outlets 7, and the water flow direction of the multiple outlets 7 is vertically downward and located inside the semi-circular shell 2. A valve 19 is provided at the connection between the sewage branch pipe 5 and the main sewage pipe 6. The main sewage pipe 6 is connected to an external sewage source, and the total flow rate and the flow and closure of the sewage branch pipes are controlled by the valve 19. The sewage branch pipe 5 has multiple outlets 7 evenly distributed at its bottom, spraying sewage vertically downward. The multiple outlet design avoids excessively high local concentrations and improves treatment uniformity; the vertically sprayed water impacts the packing plate, promoting oxygen dissolution and microbial mixing; the valve 19 can be dynamically adjusted according to the influent water quality to adapt to different load requirements.

[0029] The semi-circular housing 2 has bases 1 on both sides of its bottom, and a drain valve on one side of its bottom. The bases 1 are located on a support platform at the bottom of the semi-circular housing 2 and are fixedly connected to both sides of the bottom. They provide stable support to prevent vibration or tipping during equipment operation; they also raise the height of the semi-circular housing 2, facilitating the operation and maintenance of the bottom drain valve. The drain valve is located at the lowest point of the housing bottom and periodically discharges accumulated sludge or treated residue. Gravity-driven sludge discharge reduces the frequency of manual cleaning.

[0030] A motor bracket 13 is fixed to the outer wall of one end of the semi-circular shell 2. A drive motor 12 is fixed to the top of the motor bracket 13. A drive gear 11 is fixed to one end of the output shaft of the drive motor 12, and a driven gear 10 is fixed to one end of the main shaft 8. The drive gear 11 and the driven gear 10 mesh with each other. The drive motor 12 is fixed to the outer wall of the shell through the motor bracket 13, and its output shaft is connected to the drive gear 11. The driven gear 10 is fixed to one end of the main shaft and meshes with the drive gear to form a reduction transmission mechanism. The motor drives the main shaft 8 to rotate, which in turn drives the packing plate to rotate, realizing alternating contact between sewage and air. This eliminates the need for an air pump to meet the oxygen requirements of aerobic microorganisms, reducing energy consumption and equipment complexity.

[0031] There are six aerobic microbial packing plates 9. U-shaped grooves are formed on the fixing plate 14 at the connection points of the aerobic microbial packing plates 9. The width of the U-shaped grooves is the same as the thickness of the aerobic microbial packing plates 9. The six U-shaped grooves are evenly distributed circumferentially on the fixing plate 14. This circumferentially even distribution of the six packing plates ensures balanced force during rotation, reducing spindle wear. The groove width matches the packing plate thickness, ensuring no shaking after installation, and the gap is controlled within 0.1mm.

[0032] During wastewater microbial treatment, the drive motor 12 drives the main shaft 8 to rotate, which in turn drives the aerobic microbial packing plate 9 to rotate. During rotation, the aerobic microbial packing plate 9 can fully contact the wastewater and air, eliminating the need for an air pump and ensuring the oxygen supply for the microorganisms. Furthermore, during installation and disassembly of the aerobic microbial packing plate 9, the aerobic microbial packing plate 9 is connected to the U-shaped groove on the fixing plate 14. During installation, the aerobic microbial packing plate 9 is directly pressed into the U-shaped groove. During the pressing process, the inclined surfaces on both sides of the triangular blocks 15 at both ends of the aerobic microbial packing plate 9 will squeeze the positioning rod 18, causing the positioning rod 18 to retract until the aerobic microbial packing plate 9 is pressed into place. Then, under the elastic force of the spring 17, the positioning rod 18 extends above the triangular blocks 15 to position the aerobic microbial packing plate 9, thus completing the installation. Similarly, when it is necessary to disassemble the aerobic microbial packing plate 9, simply squeeze the positioning rod 18 and pull out the aerobic microbial packing plate 9. The installation is convenient and quick.

[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
