Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a low-energy biofilm wastewater treatment device. Background Technology

[0002] With the development of industrial production and the acceleration of urbanization, the amount of sewage discharged is increasing day by day, and the requirements for sewage treatment are becoming more and more stringent. Biofilm treatment, as a commonly used and effective sewage treatment process, utilizes the biofilm formed by the attachment and growth of microorganisms to decompose pollutants.

[0003] In the prior art, such as Chinese Patent No. CN222017408U, a biofilm reactor for river sewage treatment includes an inlet pipe, a biofilm reaction tank, an oxygenation device, and an outlet pipe. The end of the inlet pipe is located at the center of the top of the biofilm reaction tank. The oxygenation device is located at the right end of the biofilm reaction tank near the top. The outlet pipe is located at the right end of the biofilm reaction tank near the bottom. The biofilm reaction tank includes a door, a filter screen, and a biofilm reaction device. In this invention, the filter screen in the biofilm reaction tank has fine pores, which can filter out blocky objects and excess substances, avoiding a reduction in the working efficiency of the biofilm reaction device. The multi-layered filter screen can increase the adsorption capacity of the biofilm reaction device and improve the efficiency of microorganisms in the packing material in purifying sewage. Oxygen is generated by the aerator in the oxygenation device and introduced into the water through multiple oxygen outlet holes on the oxygen delivery pipe, thereby increasing the activity of aerobic organisms.

[0004] Although the device achieves wastewater filtration, replacing the packing material inside the installation box is quite cumbersome. It requires opening the box door, removing the installation box from the reaction chamber, separating the installation block from the installation box, and then removing and replacing the packing material inside the installation box. This makes the packing material replacement time-consuming and labor-intensive, thus affecting the efficiency of wastewater purification. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figure 1 - Figure 5This utility model provides a technical solution: a low-energy biofilm wastewater treatment device, including a reaction tank 1. An inlet pipe 2 and an outlet pipe 3 are fixedly connected to the surface of the reaction tank 1. A valve 22 is fixedly connected to the surface of the inlet pipe 2. A filter plate 23 is fixedly connected inside the reaction tank 1. A square groove 4 is opened on the surface of the reaction tank 1. A slot 5 is opened at the bottom of the square groove 4. A support frame is inserted inside the slot 5. The support frame includes a frame body 6 and a frame cover 7. A T-shaped groove 11 is opened on the surface of the frame body 6. A T-shaped rod 10 is fixedly connected to the surface of the frame cover 7. The T-shaped rod 10 is slidably connected inside the T-shaped groove 11. The inside of the frame body 6 is filled with biofilm filler 17. A locking block 12 is fixedly connected to the surface of the frame cover 7. A locking seat 13 is fixedly connected to the surface of the reaction tank 1. A locking pin 14 is slidably connected inside the locking block 12. A spring 15 and a push plate 16 are fixedly connected to the surface of the locking pin 14. The locking pin 14 is inserted inside the locking seat 13.

[0025] like Figure 4 As shown, there are two sets of locking pins 14, which are symmetrically distributed on both sides of the middle part of the surface of the frame cover 7. This can improve the stability of the connection between the frame cover 7 and the reaction chamber 1.

[0026] like Figure 4 As shown, a sealing gasket 8 is provided inside the square groove 4. The sealing gasket 8 is located between the frame cover 7 and the bottom of the square groove 4. This can improve the sealing effect between the frame cover 7 and the square groove 4 and prevent leakage.

[0027] like Figure 2 As shown, the surface of the reaction chamber 1 is embedded with an observation window 9, which is made of transparent glass. The inside of the reaction chamber 1 can be observed here, making it easy to grasp the relevant conditions and water level inside the reaction chamber 1.

[0028] like Figure 2 and Figure 3 As shown, an oxygenation device 24 is fixedly connected to the surface of the reaction chamber 1, and an aeration pipe 25 is fixedly connected to the surface of the oxygenation device 24. The aeration pipe 25 penetrates the reaction chamber 1, which can provide oxygen to the microorganisms attached to the biofilm packing 17 and increase the activity of the microorganisms.

[0029] like Figure 2 As shown, a slag discharge pipe 26 is fixedly connected to the bottom of the reaction chamber 1. A sealing cover 27 is provided on the surface of the slag discharge pipe 26, which facilitates the discharge of impurities filtered by the filter plate 23 from the inside of the reaction chamber 1.

[0030] like Figure 3 and Figure 4As shown, a circular hole 18 is provided on the surface of the reaction chamber 1. A connecting rod 19 is rotatably connected inside the circular hole 18. A handle 21 and a brush 20 are fixedly connected to both ends of the connecting rod 19, respectively. The bristles of the brush 20 abut against the filter plate 23. This can clean the impurities attached to the mesh of the filter plate 23, and prevent the impurities from adhering to the filter plate 23 and clogging the pores of the filter plate 23, thus affecting the filtration effect and filtration efficiency of the filter plate 23 on sewage.

[0031] The operating method and working principle of this device are as follows: First, open valve 22 on inlet pipe 2 to allow wastewater to enter the reaction tank 1. After being filtered by filter plate 23, it flows into the front end of frame 6. In the biofilm reaction zone, oxygenation device 24, controlled by an externally connected intelligent control system, precisely aerates the reaction tank 1 through aeration pipe 25, providing a suitable oxygen environment for microorganisms. This promotes the growth and reproduction of microorganisms on the biofilm packing 17, decomposing organic matter, nitrogen, phosphorus, and other pollutants in the wastewater. Furthermore, it avoids the excessive aeration common in traditional aeration methods. The energy waste caused by aeration is effectively reduced, thus significantly lowering energy consumption. Subsequently, the wastewater purified by microorganisms is discharged through the effluent pipe 3. When impurities adhere to the filter plate 23, rotating the handle 21 causes the connecting rod 19 and brush 20 to rotate. The bristles of the brush 20 contact the filter plate 23, cleaning away the impurities attached to the pores. This cleans the impurities adhering to the mesh of the filter plate 23, preventing them from clogging the pores and affecting the filtration effect and efficiency of the filter plate 23. When it is necessary to replace the biofilm packing 17 inside the frame 6, press the push plate 16. The push plate 16 drives the locking pin 14 to slide inside the locking block 12 and squeeze the spring 15, causing the locking pin 14 to disengage from the locking seat 13. Then, grasp the handle 21 on the frame cover 7 to lift the frame 6 part of the support frame out of the slot 5 on the reaction chamber 1. Push the frame cover 7 to disengage the T-shaped rod 10 on the frame cover 7 from the T-shaped slot 11 on the frame 6. Then the biofilm packing 17 can be replaced. This process achieves the purpose of fixing the support frame and the reaction chamber 1 together. On the other hand, it also makes the disassembly and assembly of the support frame more convenient, and makes the replacement of the biofilm packing 17 in the frame 6 simpler and faster, improving the work efficiency of replacing the biofilm packing 17. The sealing gasket 8 between the frame cover 7 and the bottom of the square groove 4 improves the sealing effect between the square groove 4 and the frame cover 7. When a large amount of impurities accumulate on one side of the filter plate 23, the sealing cover 27 on the slag discharge pipe 26 is opened, so that the impurities in the reaction tank 1 are discharged with the slag discharge pipe 26. When purifying sewage, the internal condition and water level of the reaction tank 1 can be monitored at all times through the observation window 9.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
