Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a suspended fiber biological packing material. Background Technology
[0002] Suspended fiber biological packing is an important carrier in the biofilm process of wastewater treatment. Its core function is to provide an environment for microorganisms to attach and grow efficiently, thereby enhancing the degradation process of pollutants. Most of them are composed of an upper shell and a lower shell, and are filled with woven filaments, biological sponges and other fillers. After being assembled, they form a spherical structure that moves randomly in the water.
[0003] CN206188476U discloses a biological carrier suspension packing material. This packing material is an overall spherical biofilm carrier composed of two interlaced inner and outer layers. The outer layer is a fishnet-like sphere, and the inner layer is a rotating sphere. The biological carrier suspension packing material is cast from vinylidene material. The inner layer of the biological carrier suspension packing material is a melon-slice, combined, or snake-skin filament elastic material. This utility model uses a scientific formula and special processes to modify and construct the polymer material. It mainly functions as a biofilm carrier while also retaining suspended solids. It features strong biological adhesion, large specific surface area, high porosity, good chemical and biological stability, durability, no leaching of harmful substances, no secondary pollution, UV protection, anti-aging, and strong hydrophilicity. During use, it facilitates microbial growth, is easy to replace, is acid and alkali resistant, anti-aging, unaffected by water flow, has a long service life, produces little residual sludge, and is easy to install.
[0004] Based on the above, the upper and lower shells of suspended packing are mostly injection molded from high molecular polymers, with a relatively fixed density. When the water flow disturbance in the pool is weak, such as insufficient aeration or flow velocity <0.2m / s, the packing may float on the water surface because its overall density is lower than that of water, i.e., buoyancy is greater than gravity. This reduces the effective contact area between the packing and the sewage, decreases the treatment efficiency, and may also increase maintenance costs due to abnormal biofilm shedding or equipment blockage. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a suspended fiber biological packing material that occupies a small volume during transportation, has an easily assembled upper and lower shell, high structural strength, and can be counterweighted to meet the requirements for settling, thereby increasing its effective contact area with sewage, improving treatment efficiency, and avoiding increased maintenance costs due to abnormal biofilm shedding or equipment blockage.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A suspended fiber biological packing material includes an upper shell, a lower shell, limiting rings, fixing plates, a first connecting box, a second connecting box, and a counterweight adjustment assembly; the lower shell is disposed below the upper shell; two limiting rings are provided, and the two limiting rings are respectively fixedly connected inside the upper shell and the lower shell; two fixing plates are provided, and the two fixing plates are respectively fixedly connected inside the two limiting rings; two first connecting boxes are provided, and the two first connecting boxes are respectively fixedly connected to the left and right sides of the bottom of the upper shell; two second connecting boxes are provided, and the two second connecting boxes are respectively fixedly connected to the left and right sides of the top of the lower shell; two sets of counterweight adjustment assemblies are provided, and the two sets of counterweight adjustment assemblies are respectively disposed inside the two limiting rings.
[0007] Preferably, the counterweight adjustment assembly includes: a mating groove and a mating block; the mating groove is formed inside the limiting ring; the mating block is fixedly connected to the bottom of the limiting ring.
[0008] Preferably, the counterweight adjustment component further includes: a first placement groove and a second placement groove; the first placement groove is formed at the bottom of the limiting ring; and the second placement groove is formed inside the mating block.
[0009] Preferably, the counterweight adjustment assembly further includes a cover plate; the cover plate is inserted into the fixed plate.
[0010] Preferably, the suspended fiber biological packing material further includes: a quick-connect assembly; the quick-connect assembly is provided in two sets, and the two sets of quick-connect assemblies are respectively disposed inside the two first connecting boxes.
[0011] Preferably, the quick-connect assembly includes: a sliding plate, a pressing post, and a fixing post; the sliding plate is slidably connected inside the first connecting box; the pressing post is fixedly connected to the front of the sliding plate and is slidably connected to the first connecting box; the fixing post is fixedly connected to the front of the sliding plate and is slidably connected to the first connecting box.
[0012] Preferably, the quick-connect assembly further includes: a fixing spring and a fixing groove; the front end of the fixing spring is fixedly connected to the back of the sliding plate, and the rear end of the fixing spring is fixedly connected to the inside of the first connecting box; the fixing groove is formed inside the second connecting box.
[0013] The beneficial effects of this novel suspended fiber biological packing material are as follows:
[0014] (1) When the upper and lower shells of the suspended fiber biological packing material of this utility model are packed and transported, they can be tightly fitted by the mating block and the mating groove to achieve layer-by-layer stacking, which not only improves the stability of transportation but also reduces the volume occupied. When facing situations where the water flow disturbance in some sewage tanks is weak, stones, gravel and other weight-increasing materials can also be filled into the mating block to effectively sink into the sewage tank and ensure the use effect.
[0015] (2) When splicing the upper shell and lower shell of the suspended fiber biological filler of this utility model, first press the pressing column backward to drive the sliding plate and the fixing column to move backward synchronously. Then insert the bottom of the first connecting box into the second connecting box. After releasing the pressing column, the upper shell and the lower shell can be quickly fixed. Compared with the traditional buckle fixing, it is more secure and not easy to separate. When it is necessary to refill the sponge or other materials in the shell, just press the pressing column again to quickly separate the upper shell and the lower shell. The operation is more convenient.
[0016] (3) The suspended fiber biological filler of this utility model achieves layer-by-layer stacking by tightly fitting the mating block after the upper shell is flipped and the mating groove of the lower shell. This can not only improve the stability during transportation, but also greatly reduce the volume occupied. The mating block can be filled with weight-adding materials such as stones and gravel, which can effectively meet the sinking requirements in low water flow disturbance scenarios. The setting of the first connecting box and the second connecting box greatly accelerates the splicing speed and structural strength of the upper shell and the lower shell.
