Description

Technical Field

[0001] The present invention belongs to the technical field of water quality treatment, and particularly relates to a biological incubator for river water quality cleaning and its usage method. Background Art

[0002] For example, a black and odorous river water purification device is disclosed in Chinese Patent No. 201710103624.X. Its bracket is provided with a solidified microorganism tube, an ecological base, and an air diffuser tube, and the air diffuser tube is connected to a compressor through an air pipe. By moving the guide rod along the guide rail, it can adapt to different water depth ranges at will, meeting the requirements of various river channels with different water depths, and also overcoming the problem of equipment stranding caused by the change of river water level during the flood season.

[0003] However, when this incubator is actually used, there will be insufficient aeration, and it is difficult to effectively control the aeration volume during aeration. At the same time, since this air diffuser tube is directly preset in the containing box body, the ventilation direction is in one direction, and it is difficult to form a turbulent flow in the bearing box body. Although the aeration component can provide sufficient nutrients and oxygen in the sewage for the microorganisms in the bearing box body, this kind of microorganism adheres to a local position in the bearing box body, making it difficult for the microorganisms adhering to the local position in the box body to be removed through direct water passing and aeration, affecting the amount of microorganisms removed during aeration, causing it to decrease, and making it difficult to achieve an effective sewage treatment effect. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a biological incubator for river water quality cleaning and its usage method, which solves the above-mentioned technical problems existing in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A biological incubator for river water quality cleaning includes a box body and an aeration module arranged in the box body. The box body is integrally in a cavity structure with an open upper part;

[0007] The aeration module includes an air ventilation pipe and an air diffuser head. The air ventilation pipe extends to the bottom position of the cavity of the box body, and at the same time, the air diffuser head is located on the air ventilation pipe at the bottom and is movably connected. Through the ventilation of the air ventilation pipe, the aeration operation of the air diffuser head at the bottom is realized;

[0008] The air diffuser head is integrally in a disc-shaped structure, and the air outlet of the disc-shaped accommodation cavity in the middle where the air diffuser head is located faces upward. At the same time, a bearing assembly is arranged in the disc-shaped accommodation cavity and a spray head is located at the side position of the air diffuser head. There are several groups of spray heads, and the spray heads form an inclination angle with the central axis of the disc-shaped accommodation cavity, so that when multiple groups of spray heads ventilate simultaneously, the whole air diffuser head is driven to rotate self-rotationally;

[0009] The cavity of the box is filled with a gel component;

[0010] The porosity of the gel component is 82% to 92.4%, and the material density is 1380 to 1500 kg·m -3 .

[0011] Furthermore, the water inlet pipe where the box is located is located at the top of the upper layer, and the water outlet pipe is located at the bottom of the lower layer.

[0012] Furthermore, the rear end portion of the aeration head is spherically connected to the ventilation pipe.

[0013] Furthermore, the box body divides the open cavity into two left and right parts through the middle partition, namely chamber A and chamber B, and the top height of the partition is lower than the height of the outer edge of the box body.

[0014] Furthermore, the A chamber and the B chamber separated by the box body are filled with gel components respectively, and the gel components are in a block structure as a whole, so that a plurality of gel components are filled in the cavities where the A chamber and the B chamber are located.

[0015] Furthermore, a stirring assembly is provided in the cavity structure where the box is located, so that the stirring assembly extends into the bottom of chamber A and chamber B, and drives the disturbance of water in chamber A and chamber B through the stirring assembly.

[0016] Furthermore, the bearing assembly of the aeration head includes a first bearing frame and a second bearing frame, and gas is discharged forward through the gas outlet at the front end of the first bearing frame, and a buffer layer is filled in the gap between the first bearing frame and the second bearing frame, so that gas passes through the buffer layer and overflows from the top gas outlet of the second bearing frame on the outside;

[0017] The first load-bearing frame is connected to the inner side of the disc-shaped accommodating cavity through an elastic member;

[0018] Furthermore, the first supporting frame and the second supporting frame are both hemispherical structures that protrude forward as a whole, and the outer edges of the first supporting frame and the second supporting frame are in contact with the inner wall of the disc-shaped accommodating cavity, and reciprocate along the extension direction of the inner wall.

[0019] Furthermore, the first supporting frame moves upward when the ventilation volume of the aeration head increases, and enables the nozzle to communicate with the ventilation space in the disc-shaped accommodating cavity.

[0020] Furthermore, the first load-bearing frame is connected to the second load-bearing frame via a connecting member.

[0021] Beneficial effects of the present invention:

[0022] 1. The gel component used in this device is suspended and carried in the cavity of the box body. It has very fine and abundant pores, which can provide more attachment space for the reproduction of microorganisms such as bacteria, fungi, algae, protozoa, and metazoans, and form a biological film. At the same time, large particle impurity suspensions will be blocked by the fine pores. During backwashing, the attached biological film can fall off quickly and can be reused repeatedly.

[0023] 2. The aeration head used in this device has two ventilation components. First, when passing a small amount of gas, ventilation is achieved only through the gaps generated by the first load-bearing framework and the second load-bearing framework. This ventilation method is to provide sufficient oxygen components for the microorganisms in the gas. When the gas volume increases, the nozzles on the side will also ventilate synchronously. When the nozzles ventilate, they will drive the entire aeration head to rotate self - sufficiently, thereby realizing the disturbance of the gas in the water body, and then promoting the shedding of the biological film on the gel component in the water body, improving the efficiency.

[0024] 3. The overall structure of this device is mobile. It can, according to needs, timely change the usage environment of the equipment, can be reused, and when discharging water, the biomass rich in the water can be increased by 10 - 20% compared with the existing aeration equipment.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1-4 shown, an embodiment of the present invention provides a biological incubator for cleaning river water quality, including a box body 1 and an aeration module 2 arranged in the box body 1. The box body 1 is integrally in a cavity structure with an open upper part. The aeration module 2 is located in the cavity structure. The box body 1 divides the open cavity into two parts, namely an A chamber 111 and a B chamber 112, by a middle partition 11. At the same time, the top height of the partition 11 is lower than the height of the outer edge of the box body 1. Gel components 3 are respectively filled in the A chamber 111 and the B chamber 112 separated by the box body 1, and the gel components 3 are integrally in a block structure, so that a plurality of gel components 3 are filled in the cavities where the A chamber 111 and the B chamber 112 are located. This setting can provide a good spatial environment for the attachment of microorganisms. At the same time, when the aeration increases, the microorganisms attached to the gel components 3 can quickly fall off and be discharged from the box body 1. The water inlet pipe 101 where the box body 1 is located is at the upper layer top for supplying sewage.

[0039] The filler of this gel component 3 is mainly a multi-void structure, having very fine and rich pores (pores in an approximately conical shape, not specifically drawn in the figure), making the water flow disordered and generating many vortices. The vortices separate the plankton according to density and retain them at different positions inside the filler. It contains microorganisms such as bacteria, fungi, algae, protozoa, and metazoans. These microorganisms combine with the surface of the filler and multiply in large numbers, thus forming a biofilm (film formation). Large particle suspensions are easily intercepted by the corrugated pores, and the porosity is high (between 82% and 92.4% according to the filler size). The filtration resistance is small, and filtration can be carried out efficiently and smoothly. Its material is light (the density is between 1380 and 1500 kg·m -3), during backwashing (i.e., when the aeration volume increases), the packing is in a fluidized state, and the suspended solids can be easily cleaned (i.e., the biofilm formed by microorganisms directly falls off from the gel component).

[0040] In addition, the packing has high chemical and geometric stability and strong resistance to oxidants, reductants, and strong acids. This project is a suspended water purification treatment device integrating a power device with this packing as the biological carrier. The device can be flexibly placed in various polluted water bodies and undergoes two processes: filtration and purification (solid and liquid phases) and backwashing (gas, solid, and liquid phases), which alternate and cycle. Parameters such as the filtration rate, device volume, and packing size of the suspended water purification treatment device need to be determined according to the impact on the amount of microorganisms (biofilm amount) bound to the packing surface.

[0041] This gel component 3 is suspended in the water body. The suspended solid particles in the pumped sewage are not easily attached (the suspended solid particles are heavier), so it is not easily blocked. At the same time, even when the water level is too high, the gel component 3 will not be affected by the uneven distribution of hydrostatic shear stress. The packing formed by this gel component 3 has strong toughness and hydrophilic suspension ability and can be used stably for a long time in a micro-stirred environment. There will be no phenomena such as the packing sinking to the bottom or floating to the surface.

[0042] As Figures 5-9 shown, the aeration module 2 includes an air vent pipe 21 and an aeration head 22. The air vent pipe 21 extends to the bottom position of the cavity of the box body 1. At the same time, the aeration head 22 is located on the bottom air vent pipe 21 and is movably connected (the rear end where the aeration head 22 is located is connected to the air vent pipe 21 in a spherical shape, and this method can achieve the relative rotation of the aeration head 22). By ventilating the air vent pipe 21, the aeration operation of the bottom aeration head 22 is realized.

[0043] The aeration head 22 is integrally in a disc-shaped structure, and the air outlet of the disc-shaped accommodation cavity 201 in the middle of the aeration head 22 faces upward, which can achieve the aeration operation from the bottom to the top. At the same time, a bearing component 221 is arranged in the disc-shaped accommodation cavity 201, and a spray head 222 is arranged on the side of the aeration head 22. There are several groups of spray heads 222, and the spray heads 222 form an angle with the central axis of the disc-shaped accommodation cavity 201 (so that the spray heads 222 are arranged radially outward from the central axis). When multiple groups of spray heads 222 ventilate simultaneously, they can drive the entire aeration head 22 to rotate self-rotationally.

[0044] The supporting assembly 221 of the aeration head 22 includes a first supporting frame 2211 and a second supporting frame 2212. Gas is discharged forward through the air outlet at the front end of the first supporting frame 2211. At this time, the first supporting frame 2211 is connected to the inner side of the disc-shaped accommodating cavity 201 through the elastic member 2214; the gap between the first supporting frame 2211 and the second supporting frame 2212 is filled with a buffer layer 2213 (the buffer layer 2213 has a multi-through hole structure, which can realize the effective passage of gas), so that the gas passes through the buffer layer 2213 and overflows from the top air outlet of the second supporting frame 2212 on the outside (the first supporting frame 2211 and the second supporting frame 2212 have a frame-like hollow structure as a whole, and are a hemispherical structure protruding forward as a whole).

[0045] like Figure 7 As shown, when the ventilation volume of the aeration head 22 is small, the pressure on the elastic member 2214 is small, and the ventilated gas passes through the first supporting frame 2211, the second supporting frame 2212 and the buffer pad layer 2213, so as to realize aeration operation for the water contained in the box body 1. At this time, the ventilation effect can provide sufficient oxygen supply for the organisms in the water body (attached to the gel component 3).

[0046] like Figure 9 As shown, when the ventilated gas flow increases, the first supporting frame 2211 moves upward under the impact of the gas, and a limiting protrusion 2201 is provided at the outer edge of the disc-shaped accommodating cavity 201 to prevent the second supporting frame 2212 ( Figure 11 As shown in FIG. 1 , the impact force of the gas is too great and the disc-shaped receiving cavity 201 may fall off (as shown in FIG. 1 ). Figure 8 As shown, within the range limited by the limiting protrusion 2201, the second supporting skeleton 2212 can realize reciprocating motion within the elastic limit of the elastic member 2214), until the first supporting skeleton 2211 is pushed forward to expose the air inlet of the nozzle 222 where the disc-shaped accommodating cavity 201 is located (the nozzle 222 is not used as a vent for ventilation at the beginning), and because the nozzle 222 as a whole is arranged in multiple groups of inclined shapes, when the nozzle 222 is pressed by gas, gas will be discharged from the front end, and the gas discharge from the front end of the nozzle 222 will drive the rotation of the aeration head 22 as a whole. The effect of the gas rotation will cause the disturbance in the surrounding water body, thereby realizing the detachment of the biofilm attached to the gel component 3 and overflowing from the water outlet pipe 102 at the bottom.

[0047] In order to further improve the effect of removing the biofilm on the gel component 3, a stirring component 4 is provided in the cavity structure where the box body 1 is located, so that the stirring component 4 extends to the bottom of the A chamber 111 and the B chamber 112, and the stirring component 4 drives the disturbance of the water in the A chamber 111 and the B chamber 112.

[0048] When the flow rate of the ventilation air decreases, the elastic member 2214 in which the first load-bearing framework 2211 and the second load-bearing framework 2212 are located as a whole will rebound and reset.

[0049] Both the first load-bearing framework 2211 and the second load-bearing framework 2212 are such that the outer edges where the first load-bearing framework 2211 and the second load-bearing framework 2212 are located are fitted to the inner wall of the disc-shaped accommodating cavity 201, enabling reciprocating movement back and forth along the extending direction of the inner wall.

[0050] In order to adjust the ventilation volume, the first load-bearing framework 2211 is connected to the second load-bearing framework 2212 through a connecting member 2215 ( Figure 10 as shown). The connecting member 2215 adopts a threaded connection method, which can adjust the clearance thickness between the first load-bearing framework 2211 and the second load-bearing framework 2212, so as to fill buffer cushions 2213 with different thicknesses, and the change of the aeration volume can be achieved (according to different depths).

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
