Description

A type of suspended ball-type fluidized bed composite wastewater treatment filter media Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a suspended ball-type fluidized bed composite wastewater treatment filter media. Background Technology

[0002] Rural domestic sewage treatment is of great significance to improving the rural living environment. In recent years, a large number of rural biochemical sewage treatment facilities have been built. However, due to the increasing age of some rural domestic sewage treatment facilities, the treatment effect of the facilities has dropped significantly.

[0003] The original packing material in the site was lost and severely ineffective. Some of the packing material was fixed inside the equipment tank, making replacement difficult. As the grid plates of the aerobic and anaerobic tanks fell off, the original fluidized bed packing material was prone to loss and blockage of the internal water pipes.

[0004] To address the aforementioned technical problems, a suspended ball-type fluidized bed composite wastewater treatment filter media is proposed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, this utility model provides a suspended ball meridian fluidized bed composite wastewater treatment filter material, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended ball meridian fluidized bed composite sewage treatment filter material, including a sewage treatment tank, wherein a sewage input pipe is fixedly connected to the bottom of the sewage treatment tank, and a drain outlet is provided at the top of the sewage treatment tank;

[0007] The wastewater treatment tank is equipped with lightweight suspended spheres. The surface of the lightweight suspended spheres has through holes. The interior of the lightweight suspended spheres is filled with meridian packing units. The periphery of the lightweight suspended spheres is filled with a fluidized bed packing layer. A connecting component is provided between two lightweight suspended spheres.

[0008] When water flows through the suspended sphere water treatment composite filter media, the meridian-like filler units inside the lightweight suspended spheres first come into contact with the water, utilizing their adsorption and decomposition properties to remove some impurities from the water. Furthermore, the internal meridian structure is more conducive to the growth and attachment of microorganisms. Simultaneously, the outer surface of the lightweight suspended spheres...

[0009] The fluidized bed packing layer forms a dynamic flow under the flushing of water, constantly colliding, rubbing and adsorbing impurities in the water, thereby further improving the purification effect. The combination of the suspension of the lightweight suspended spheres and the fluidity of the fluidized bed packing layer makes the entire filter media system have higher treatment efficiency and longer service life.

[0010] As a preferred technical solution of this utility model, the lightweight suspended sphere is made of polyethylene or polypropylene, with a pore diameter of 3-8 mm and a porosity of ≥30%.

[0011] Lightweight suspended spheres provide a stable carrier and prevent filler loss.

[0012] As a preferred embodiment of this utility model, the meridian filler unit is a porous fiber bundle or an elastic biological rope.

[0013] The meridian packing material inside the meridian packing unit enhances the biofilm formation ability of microorganisms.

[0014] As a preferred technical solution of this utility model, the fluidized bed packing layer is activated carbon or ceramic particles with a surface coated with a biological coating, and the particle size is 1-5mm.

[0015] Fluidized bed packing layers improve pollutant adsorption efficiency through dynamic friction.

[0016] As a preferred embodiment of this invention, the connecting component includes a central shaft penetrating the sphere and a corrosion-resistant connecting rope.

[0017] The distribution density of lightweight suspended spheres can be controlled by adjusting the length of the connecting rope to adapt to fluctuations in water quality.

[0018] As a preferred embodiment of this utility model, the bottom layer of the sewage treatment tank is formed with a water distribution cavity, which is connected to the sewage input pipe, and a drain pipe connected to the sewage treatment tank is fixedly installed on the inner top surface of the water distribution cavity.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Lightweight suspended spheres provide a stable carrier, preventing the loss of filter media. The internal meridian packing enhances the biofilm formation capacity of microorganisms. Together with the fluidized bed packing layer outside the lightweight suspended spheres, they form a dynamic flow under the scouring of water, constantly colliding, rubbing, and adsorbing impurities in the water, thereby further improving the purification effect. The combination of the suspension of the lightweight suspended spheres and the fluidity of the fluidized bed packing layer makes the entire filter media system have higher treatment efficiency and a longer service life.

[0026] 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.

[0027] Please refer to Figures 1-4. A suspended ball meridian fluidized bed composite wastewater treatment filter material includes a wastewater treatment tank 1, a wastewater inlet pipe 2 fixedly connected to the bottom of the wastewater treatment tank 1, and a drain outlet 3 opened at the top of the wastewater treatment tank 1.

[0028] The wastewater treatment tank 1 contains lightweight suspended spheres 4, each with through holes 401 on its surface. The lightweight suspended spheres 4 are filled with a network of filler units 6, and surrounded by a fluidized bed filler layer 7. A connecting component connects two lightweight suspended spheres 4. When water flows through the suspended sphere water treatment composite filter media, the network of filler units 6 inside the lightweight suspended spheres 4 first comes into contact with the water, utilizing their adsorption and decomposition properties to remove some impurities. Furthermore, their network structure promotes the growth and attachment of microorganisms. Simultaneously, the fluidized bed filler layer 7 outside the lightweight suspended spheres 4 forms a dynamic flow under the scouring of water, continuously colliding, rubbing, and adsorbing impurities in the water, thereby further improving the purification effect. The suspension properties of the lightweight suspended spheres 4 and the flow properties of the fluidized bed filler layer 7...

[0029] The combination of dynamism and flexibility gives the entire filter media system higher processing efficiency and a longer service life.

[0030] Specifically, the lightweight suspended sphere 4 is made of polyethylene or polypropylene, with through-hole 401 having a pore diameter of 3-8mm and a porosity of ≥30%. The lightweight suspended sphere 4 provides a stable carrier and prevents filler loss.

[0031] Specifically, the meridian packing unit 6 is a porous fiber bundle or elastic biological rope, and the meridian packing inside the meridian packing unit 6 enhances the biofilm formation ability of microorganisms.

[0032] Specifically, the fluidized bed packing layer 7 consists of activated carbon or ceramic particles with a surface coated with a bio-coating, with a particle size of 1-5 mm. The fluidized bed packing layer 7 improves the adsorption efficiency of pollutants through dynamic friction.

[0033] Specifically, the connecting components include a central shaft 402 that runs through the sphere and a corrosion-resistant connecting rope 5. The distribution density of the lightweight suspended sphere 4 is controlled by adjusting the length of the connecting rope to adapt to water quality fluctuations.

[0034] Specifically, a water distribution cavity 201 is formed at the bottom of the sewage treatment tank 1. The water distribution cavity 201 is connected to the sewage inlet pipe 2. A drain pipe 202 connected to the sewage treatment tank 1 is fixedly installed on the inner top surface of the water distribution cavity 201.

[0035] Working principle: Wastewater is transported to the bottom of wastewater treatment tank 1 through wastewater inlet pipe 2. The wastewater flows upward from the bottom of wastewater treatment tank 1. When the water flows through the suspended ball water treatment combined filter media, the meridian packing unit 6 inside the lightweight suspended ball 4 first comes into contact with the water, using its adsorption and decomposition properties to remove some impurities in the water. Moreover, its internal meridian structure is more conducive to the growth and attachment of microorganisms. At the same time, the fluidized bed packing layer 7 outside the lightweight suspended ball 4 forms a dynamic flow under the flushing of water, constantly colliding, rubbing and adsorbing impurities in the water, thereby further improving the purification effect. The combination of the suspension of the lightweight suspended ball 4 and the fluidity of the fluidized bed packing layer 7 makes the entire filter media system have higher treatment efficiency and longer service life. The filtered water is discharged out through the drain outlet 3.
