[0002] People have increasingly high requirements for a healthy environment, and the government attaches great importance to the treatment of waste gas and sewage generated by related industries. The biological trickling filter tower absorbs the odor generated by the sewage station through the pre-cultivation of microbial strains. These elements include sulfur, hydrogen, nitrogen and other gases, which generally have an odor. Biological strains can effectively absorb and decompose them, and at the same time, the gases eventually form carbon dioxide and water to achieve the purpose of deodorization and purification. In order to reduce the NIMBY effect of the sewage plant and the impact on the surrounding residents, ensure a good working environment and comply with relevant environmental protection regulations, the sewage treatment plant should be deodorized.

[0003] The existing biological trickling filter tower needs to manually enter the box body through the access hole to clean the filler when replacing the carbonaceous filler. The replacement of the filler is difficult, and the personnel entering the box body has the risk of limited space operation. Frequent disassembly and installation can increase the gap of the box body connection and easily cause the device to leak.

[0004] At the same time, the carbonaceous filler in the device is dispersedly placed in the storage device. Due to the irregular surface of the carbonaceous filler, the space utilization rate of the storage device is not high.

[0048] The inner diameter of the fixed ring 9 is the same as the inner diameter of the annular grid plate 51, and the outer diameter of the fixed ring 9 is greater than the outer diameter of the grid plate 51.

[0049] The biological treatment assembly 5 comprises a grid plate 51 abutting on the upper end of the fixed ring 9, and the grid plate 51 is wound and provided with a through hole 56 penetrating through the middle of a plurality of carbonaceous filler blocks 52 through a rubber pipe 55 to form a carbonaceous filler chain (as shown in Figure 5(Exhibition) A 2mm gap is reserved between the surface of the rubber tube 55 and the through hole 56 in the middle of the carbonaceous filler block 52. This gap allows water to flow smoothly from the opening on the surface of the rubber tube 55. This setting can improve the treatment effect of a single carbonaceous filler block 52 on sewage. At the same time, the carbonaceous filler chain composed of several carbonaceous filler blocks 52 is also easy to recycle. It can be wound on the winding roller for recycling, making recycling more convenient.

[0050] At least two biological processing components 5 are stacked on top of each other (e.g. Figure 3 As shown in the figure, the two sets of biological treatment components 5 provided in this case include, but are not limited to, those configured according to actual needs to improve the treatment effect of sewage deodorization;

The reserved space can store more air and allow the initially treated wastewater to fully contact the air and store a small amount of oxygen for microbial use. At the same time, this space allows wastewater to drip evenly onto the carbonaceous packing block 52. One end of the rubber tube 55 is closed, and the other end is fixedly connected to a water collection hood 54. The water collection hood 54 is made of the same material as the rubber tube 55 and is funnel-shaped with a small volume. It is located on the top of the carbonaceous packing block 52, allowing a small amount of wastewater to enter the interior of the carbonaceous packing block 52 through the water collection hood 54 and the rubber tube 55 for microbial treatment. The water collection hood 54 is located on one side of the upper end of the coiled carbonaceous packing block 52 and abuts against the inner cavity of the outer shell 1.

[0054] The upper end of each support rod 53 is provided with holes for easy hanging (not shown in the figure).

[0055] The spraying assembly 4 comprises a fixed rod one 41 fixed on the inner wall of the upper shell 11 by screws, a sealing sleeve 42 fixed on the middle part of the fixed rod one 41, a hollow saucer 43 for spraying rotatably arranged in the inner cavity of the lower end of the sealing sleeve 42, a rubber ring embedded in the inner cavity of the lower end of the sealing sleeve 42 and sealing the outer wall of the convex tube of the hollow saucer 43, the rubber ring being preferably made of corrosion-resistant material, the diameter of the hollow saucer 43 being smaller than the inner diameter of the outer shell 1, and the gap therebetween being 2-4 mm, so as to increase the water distribution area as much as possible;

[0056] The spraying assembly 4 further comprises a fixed rod two 46 fixed on the inner wall of the convex tube at the upper end of the hollow saucer 43, a connecting shaft 45 rotatably arranged in the inner cavity of the upper end of the sealing sleeve 42 and fixed on the upper end of the fixed rod two 46, and the mounting mode of the bearing being a prior art and the bearing being optionally a waterproof bearing;

[0057] The surface of the connecting shaft 45 is equally divided and fixed with blades 44, the blades 44 being arc-shaped, the upper end of the convex tube at the upper end of the hollow saucer 43 being located in the middle part of the sealing sleeve 42, the middle upper part of the middle part of the sealing sleeve 42 being fixedly penetrated with a water inlet pipe 47 inclined opposite to the blades 44, the inner diameter of the water inlet pipe 47 towards one end of the blades 44 being reduced to increase the water flow pressure and speed, so as to impact the blades 44 to rotate.

[0058] The other end of the water inlet pipe 47 is fixedly penetrated with the outer shell 1 and extends to the outside, the other end of the water inlet pipe 47 is connected with a water supply device, the hollow saucer 43 is located at the upper end of the carbonaceous filler block 52 and has a spacing of 10-15 cm, the lower end surface of the hollow saucer 43 is flush with the lower end surface of the upper shell 11 (as shown in Figure 3 The lower end of the hollow saucer 43 is fixedly penetrated with nozzles 48 in communication with the inner cavity of the hollow saucer 43, and the nozzles 48 cover the lower surface of the hollow saucer 43 to make the water outlet more uniform and dense.

[0059] Specifically, the lower end of the inner cavity of the outer shell 1 is a water storage part, the outer shell 1 is fixedly penetrated with a communicating vessel 8, one end of the communicating vessel 8 is located in the water storage part, and the air inlet pipe 6 is arranged close to the fixed ring 9 and has a water storage space with the bottom of the inner cavity of the outer shell 1.

[0060] The carbonaceous filler block 52, the bearing, the transparent observation window 7 and the communicating vessel 8 are prior arts, and their structures and principles will not be described in detail, the device further comprises a switch, a power supply and a controller, which are not the main technology and will not be described in detail, and the carbonaceous filler block 52 is arranged in an arc shape.

[0061] The use method of the biological trickling filter tower sewage deodorization device comprises the following steps:

[0062] SO1, before using the device, the device is installed on a platform, then the water inlet end of the water pump 2 and the air inlet pipe 6 are respectively connected with the corresponding devices outside, and one end of the water inlet pipe 47 is connected with a water supply device;

[0063] The water supply device sprays water through the water inlet pipe 47 onto the blade 44, and pushes the blade 44 to rotate, and the blade 44 drives the connecting shaft 45 to rotate on the inner ring of the bearing, and the connecting shaft 45 drives the hollow sprinkler 43 to rotate through the fixed rod two 46, and the rotating speed of the hollow sprinkler 43 depends on the water outlet pressure of the water inlet pipe 47, the greater the pressure, the faster the rotating speed of the hollow sprinkler 43, and vice versa. The sewage is gathered in the hollow sprinkler 43 and is uniformly sprayed out through a plurality of nozzles 48, which is similar to a sky curtain shower, so that the sewage fully covers the coiled carbonaceous filler block 52, thereby improving the effect of microbial treatment. The diameter of the single water column sprayed by the nozzle 48 is small, which can reduce the impact on the surface of the carbonaceous filler block 52, thereby protecting the microorganisms from being detached or killed by long-time impact. The spraying device does not need to use power to drive rotation, which effectively reduces the use cost of the device.

[0064] S02, when the sewage is subjected to microbial treatment:

[0065] The sewage first flows on the surface of the carbonaceous filler block 52 of the upper biological treatment assembly 5. The surface of the carbonaceous filler block 52 has a plurality of holes of different sizes, and microorganisms are attached to the surface. The microorganisms convert organic matter in the sewage into inorganic matter through decomposition. The microorganisms convert organic matter in the sewage into harmless substances such as carbon dioxide and water through adsorption and degradation, and use these substances as energy and nutrients for growth and reproduction. Because the size holes on the surface of the carbonaceous filler block 52 are not completely connected, the utilization rate of the surface of the carbonaceous filler block 52 is limited. The sewage flows through the openings of the rubber pipe 55 to the through hole 56 in the middle of the carbonaceous filler block 52. The through hole 56 also has a plurality of holes of different sizes. Therefore, the setting effectively increases the area of microbial attachment and further improves the sewage treatment effect. A special microbial activity promoter is used. During the domestication of functional bacteria, the activity of dominant bacteria is fully stimulated, the microbial domestication is accelerated, the operation start-up period is shortened, the number of microorganisms in a unit volume is increased, the mutual inhibition between different components in the removal process is weakened, the removal load of malodorous pollutants is greatly improved, and the operation stability of the biological trickling filter tower is improved.

[0066] S03, when the carbonaceous filler block 52 needs to be replaced:

[0067] First, the switch is opened, the external power supply through the wire for multi-stage electric push rod 34 power supply, multi-stage electric push rod 34 telescopic end extends through the slider 33 in the vertical rod 31 longitudinal slot 32 moves, thereby driving the upper shell 11 moves upwards and separates from the shell body 1, because in normal state, the upper end of the support rod 53 protrudes from the shell body 1, so the support rod 53 is convenient to connect with the external hoisting device, the hook of the hoisting device is hung in the hole of the support rod 53, thereby lifting the entire biological treatment assembly 5 and separating from the inner cavity of the shell body 1, at this time, the hoisting device moves can move and recycle the biological treatment assembly 5, the biological treatment assembly 5 located in the shell body 1 is disassembled in the same way, and the installation of the new biological treatment assembly 5 is opposite to the above operation, which can effectively and quickly replace the used biological treatment assembly 5 without damaging the trickling filter tower body.

[0068] The replaced biological treatment assembly 5 is placed in the recycling area, the water collecting cover 54 is taken up and fixed on the winding roller (not shown in the figure), the winding roller rotates through the rubber pipe 55 to wind the carbonaceous filler block 52 on the surface of the winding roller like a chain, and the recycling setting facilitates recycling, storage and transportation of the carbonaceous filler block 52.

[0069] The shell body 1 for storing a plurality of biological treatment assemblies 5 is integrally formed without splicing joints, which can increase the sealing of the carbonaceous filler structure and the biological trickling filter tower, increase the utilization rate of the storage device space, and reduce the space occupied by the storage device in the inner cavity of the shell body 1.

[0070] The lowermost biological treatment assembly 5 in the inner cavity of the shell body 1 further processes the treated sewage, thereby improving the sewage treatment effect, finally, the treated sewage enters the storage part at the bottom of the inner cavity of the shell body 1, then the water pump 2 draws out the treated sewage through the water suction pipe 10, the communicating vessel 8 is arranged to display the water level in the trickling filter tower, and the external air supply device sends air containing oxygen into the trickling filter tower through the air inlet pipe 6 to provide oxygen for microorganisms, and the technology is not described in detail.

[0071] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
