Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for phosphorus and nitrogen removal. Background Technique

[0002] Sewage contains a large amount of nitrogen and phosphorus. If the sewage is directly discharged into the water body without treatment, it will cause eutrophication of the water body, and then trigger environmental problems such as water blooms, which will have a serious impact on the aquatic ecosystem. Therefore, the treatment of sewage has also become an important part of environmental protection. At present, the phosphorus and nitrogen removal of sewage is mainly divided into biological methods, chemical methods and physical methods. The biological method uses microorganisms to achieve the conversion of nitrogen and phosphorus, while the chemical method uses the method of adding agents to react with nitrogen and phosphorus to achieve removal. The physical method is to achieve the removal of nitrogen and phosphorus through processes such as adsorption and ion exchange. Among them, the biological method is widely used because of its advantages such as high treatment efficiency, economy and practicality, and no secondary pollution.

[0003] In current biological sewage treatment, the commonly used method is the biological membrane method. By adding fillers in the sewage treatment tank, it is convenient for microorganisms to form biofilms. When the sewage passes through the biofilm, the microorganisms can achieve the removal of nitrogen and phosphorus through metabolic functions. When the current fillers are used, they need to be customized according to the specific size and size of the sewage treatment tank, and the fillers are added or removed accordingly. That is, each sewage treatment tank needs to have corresponding filler equipment. If there is no sewage treatment plan for some sewage treatment tanks temporarily, it is impossible to quickly transfer the fillers to another sewage treatment tank for use, resulting in waste of resources and increased sewage treatment costs. Content of the Utility Model

[0004] In view of this, the utility model provides a sewage treatment device for phosphorus and nitrogen removal, which can adjust the overall length and the retraction and release of the hanging fillers, so as to be suitable for different sewage treatment tanks for phosphorus and nitrogen removal.

[0023] See Figures 1 to 3, a phosphorus and nitrogen removal device for sewage treatment provided by the utility model includes a hollow tube 1, a movable rod 2, a hanging filler 3, a clamping mechanism and an adjusting mechanism. One end of the movable rod 2 extends into the hollow tube 1, and an installation groove 4 is arranged on the bottom surface of the other end. The clamping mechanism is arranged in the installation groove 4 and is used to clamp the top of the side wall of the sewage treatment tank. The hanging filler 3 is arranged on the bottom surface of the hollow tube 1 and the bottom surface of the movable rod 2; the adjusting mechanism includes a double-shaft motor 5, a lead screw 6, a fixing plate 7 and a sliding block 8. The fixing plate 7 is arranged at both ends of the hollow tube 1. The double-shaft motor 5 is arranged on the inner top surface of the hollow tube 1, and its output shaft is connected to one end of the lead screw 6. The other end of the lead screw 6 is rotatably connected to the fixing plate 7. The sliding block 8 is arranged inside the hollow tube 1, and its bottom surface is slidably connected to the inner bottom surface of the hollow tube 1. The lead screw 6 passes through the sliding block 8 and is screwed to the sliding block 8. The end of the movable rod 2 is connected to the side wall of the sliding block 8. When the movable rod 2 extends into the hollow tube 1, the hanging filler 3 is received into the hollow tube 1.

[0024] A phosphorus and nitrogen removal device for sewage treatment of the utility model is used to be erected on a sewage treatment tank. Movable rods 2 that can move are arranged at both ends of the hollow tube 1. After the movable rods 2 move, they can be suitable for the width of the sewage treatment tank. A clamping mechanism is arranged in the installation groove 4 at the end of the movable rod 2. The clamping mechanism can clamp and fix the top of the side wall of the sewage treatment tank to ensure that the entire hollow tube 1 and the movable rod 2 are stably located above the sewage treatment tank. Hanging fillers 3 are arranged on the bottom surface of the hollow tube 1 and the bottom surface of the movable rod 2. The hanging fillers 3 can hang down into the sewage treatment tank for microorganisms to form biofilms. When sewage passes through the microbial film, nitrogen and phosphorus can be decomposed under the metabolic action of microorganisms, realizing phosphorus and nitrogen removal in sewage treatment.

[0025] For the hanging filler 3, it is arranged on the movable rod 2 in a hanging manner. When the movable rod 2 is completely received into the hollow tube 1, the hanging filler 3 will be received in the hollow tube 1 in a horizontal state. When it is necessary to further extend the movable rod 2 to the outside of the hollow tube 1, drive the double-shaft motor 5. The double-shaft motor 5 can drive the lead screw 6 to rotate. The sliding block 8 converts the rotational motion of the lead screw 6 into a linear motion and drives the movable rod 2 to move outward. When the top of the hanging filler 3 on the bottom surface of the movable rod 2 moves outside the hollow tube 1, the hanging filler 3 will droop downward, thus realizing the increase of the hanging filler 3. According to the different overall lengths of the hollow tube 1 and the movable rod 2, the automatic addition and deletion of the hanging filler 3 can be realized, so as to be suitable for sewage treatment tanks of different widths, effectively utilize idle resources and reduce the sewage treatment cost.

[0028] Preferably, a slider 10 is provided on the top surface of the sliding block 8, a sliding groove 11 is provided on the inner top surface of the hollow tube 1, and the slider 10 is located in the sliding groove 11.

[0029] When the sliding block 8 moves, the slider 10 on its top can move along the sliding groove 11, preventing the movement of the sliding block 8 from deviating. At the same time, the sliding groove 11 can limit the slider 10, preventing the sliding block 8 from rotating synchronously with the lead screw 6, enabling the sliding block 8 to convert the rotational motion of the lead screw 6 into a linear motion.

[0030] Preferably, the adjusting mechanism further includes a bearing 12, the bearing 12 is provided on the opposite side walls of the fixed plate 7, and the end of the lead screw 6 away from the dual-axis motor 5 is connected to the bearing 12.

[0031] When the lead screw 6 rotates, its end can rotate under the support of the bearing 12, ensuring that the sliding block 8 can move linearly stably.

[0032] Preferably, the clamping mechanism includes a clamping plate 13 and a clamping spring 14. The clamping plates 13 are oppositely arranged in the installation groove 4. The clamping spring 14 connects the side walls of the clamping plate 13 and the side walls of the installation groove 4. The clamping mechanism further includes a sleeve 15 and a telescopic rod 16. The sleeve 15 is provided on the side wall of the installation groove 4. The clamping spring 14 is located in the sleeve 15. One end of the telescopic rod 16 is connected to the side wall of the clamping plate 13, and the other end extends into the sleeve 15 and is connected to the clamping spring 14.

[0033] A clamping area is formed between the clamping plates 13. After moving the installation groove 4 above the side wall of the sewage treatment tank, pull the clamping plates 13 to move outward. At this time, the telescopic rod 16 will move into the sleeve 15 and compress the clamping spring 14, driving the moving rod 2 to descend so that the clamping plates 13 are located between the side walls of the sewage treatment tank. Then slowly release the clamping plates 13. Under the action of the clamping spring 14, the clamping plates 13 can clamp and fix the side wall of the sewage treatment tank, ensuring the stability of the entire phosphorus and nitrogen removal device and preventing the entire hollow tube 1 and the moving rod 2 from moving when the sewage flows.

[0034] Preferably, it further includes a handle 17, and the handle 17 is provided on the top surface of the hollow tube 1.

[0035] The provided handle 17 can be used to grasp the hollow tube 1, facilitating its transfer to different sewage treatment tanks.
