Description

Technical Field

[0001] The utility model belongs to the technical field of sewage biodegradation, in particular to a sewage biodegradation device. Background Art

[0002] Sewage is wastewater generated by urban life and industrial operations. It contains large amounts of organic and inorganic matter, making it highly polluting. After undergoing environmental treatment to reduce pollutants to acceptable discharge standards, sewage can be recycled or discharged into the natural environment.

[0003] Environmentally friendly wastewater treatment primarily includes physical, chemical, and biological treatment methods. Biological treatment is the most common in the industry due to its higher environmental performance, efficiency, and effectiveness.

[0004] Specifically, microorganisms are cultured in ecological sludge and reproduce under the action of ecological sludge to produce a large number of microbial bacteria, which then perform aerobic and anaerobic degradation treatment on sewage.

[0005] However, currently sewage is treated aerobically and anaerobically separately in independent large sewage pools. The disadvantage of this method is that it occupies too large an overall volume of the sewage pool, and during the treatment process, once the microbial content in the ecological sludge decreases, the sewage degradation efficiency decreases, and the ecological sludge cannot be quickly replaced. The sewage that has not been effectively degraded cannot be transferred for treatment. Specifically, after the microbial content in the ecological sludge decreases, the large amount of sewage in the large pool is not only difficult to transfer, but once more ecological sludge is added to the pool, it is easy to cause too much sludge to accumulate in the sewage pool, making subsequent cleaning more troublesome.

[0006] Therefore, how to achieve and maintain high-efficiency degradation, and at the same time, once the degradation efficiency of ecological sludge decreases, being able to replace the ecological sludge in a timely and rapid manner and transfer the sewage conveniently is crucial to improving the microbial degradation of sewage. Utility Model Content

[0007] Based on the above background, the purpose of the present invention is to provide a sewage biodegradation device.

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A sewage biodegradation device comprises a sewage degradation tank, wherein a grid plate is fixedly connected to the sewage degradation tank;

[0010] The grid plate divides the sewage degradation tank into a plurality of independent aerobic degradation cells and anaerobic degradation cells, and the aerobic degradation cells, the anaerobic degradation cells, and the aerobic degradation cells and the anaerobic degradation cells are connected by pipeline structures.

[0011] The aerobic degradation cell and the anaerobic degradation cell are respectively fixedly connected with an ecological sludge assembly, and the ecological sludge assembly includes a crossbeam mounted on the upper end of the aeration cell, and a plurality of ecological tubes are fixedly connected to the bottom of the crossbeam, and the ecological tubes are provided with a plurality of through holes, and the ecological tubes are filled with ecological sludge;

[0012] The sewage biodegradation device further comprises an aeration mechanism arranged in the aerobic degradation cell.

[0013] Preferably, the transverse cross-section of the grid plate is a cross shape, and the grid plate divides the sewage degradation tank into a first aerobic degradation cell, a second aerobic degradation cell, and a first anaerobic degradation cell and a second anaerobic degradation cell;

[0014] The lower ends of the first aerobic degradation cell are connected to the lower ends of the second aerobic degradation cell through a pipeline structure, and the lower ends of the second aerobic degradation cell are connected to the lower ends of the first anaerobic degradation cell through a pipeline structure.

[0015] Preferably, the pipeline structure includes a pipeline, and the pipeline is fixedly installed on the grid plate; a solenoid valve is installed on the pipeline.

[0016] Preferably, the sewage degradation tank is connected to a sewage inlet pipe connected to the first aerobic degradation cell and a sewage outlet pipe connected to the second anaerobic degradation cell.

[0017] Preferably, the top of the ecological tube is connected to a feed pipe, and the pipe mouth of the feed pipe is threadedly connected to a fastening screw fastened to the beam frame.

[0018] Preferably, a cylindrical filter is fixedly connected to the outer wall of the ecological tube;

[0019] The cylindrical filter screen comprises annular seats fixedly connected to the upper and lower sides of the ecological tube, and the cylindrical filter screen is fixedly connected between the annular seats.

[0020] Preferably, a threaded hole is provided in the center of the annular seat;

[0021] The annular seat is threadedly connected to the ecological tube.

[0022] Preferably, the aeration mechanism includes a plurality of arc-shaped aeration pipes spanning between the first aerobic degradation cell and the second aerobic degradation cell, the bottoms of the arc-shaped aeration pipes are respectively connected to horizontal connecting pipes, and the air inlet ends of the horizontal connecting pipes are connected to aeration fans;

[0023] A plurality of aeration holes are provided on the arc-shaped aeration pipe.

[0024] Preferably, the arc-shaped aeration pipe comprises an arc-shaped portion, and both ends of the arc-shaped portion are integrally formed with vertical aeration pipe portions respectively located in the first aerobic degradation cell and the second aerobic degradation cell;

[0025] The vertical aeration pipe portion is provided with a plurality of aeration holes spaced apart from each other.

[0026] The utility model has the following beneficial effects:

[0027] During operation, sewage is first pumped into the first aerobic degradation cell through a sewage pipe. Within the first aerobic degradation cell, it passes through ecological sludge (commonly used in existing sewage treatment processes, containing microorganisms that degrade sewage). After a period of treatment, as microbial degradation slows, the sewage in the first aerobic degradation cell is pumped into the second aerobic degradation cell for continued degradation. This method ensures that the microorganisms in the ecological sludge maintain high degradation activity throughout the microbial degradation process.

[0028] This approach allows wastewater to be immediately transferred to a vacant degradation cell with high activity to continue degradation if microbial degradation activity decreases during the degradation process (microbial degradation is related to the pollution intensity of the wastewater). This improves the efficiency and effectiveness of microbial degradation of wastewater.

[0029] 2. During the operation of the eco-tube, microbial degradation activities are mainly carried out around the eco-tube, which solves the technical defect of traditional sewage pools that when the activity of the ecological sludge decreases, it cannot be quickly and effectively replaced. During the operation, when the activity of the degradation sludge decreases, the ecological sludge can be quickly replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] like Figure 1-5As shown, a sewage biodegradation device includes a sewage degradation tank 1, in which a grid plate 11 is fixedly connected (the transverse cross-section of the grid plate 11 is a cross shape).

[0042] The grid plate 11 divides the sewage degradation tank 1 into several independent aerobic degradation cells and anaerobic degradation cells. Specifically, it is divided into a first aerobic degradation cell 31, a second aerobic degradation cell 32, and a first anaerobic degradation cell 33 and a second anaerobic degradation cell 34. The lower ends of the first aerobic degradation cell 31 and the second aerobic degradation cell 32 are connected by a pipe structure, and the lower ends of the second aerobic degradation cell 32 and the first anaerobic degradation cell 33 are connected by a pipe structure. According to existing methods, the pipe structure includes a pipe A, which is fixedly mounted on the grid plate 11 (specifically, mounted at the lower end of the grid plate 11). According to conventional methods disclosed in the prior art, a solenoid valve (not shown) is installed on the pipe A.

[0043] At the same time, the sewage degradation tank 1 is connected to a sewage inlet pipe connected to the first aerobic degradation cell 31 and a sewage outlet pipe 12 connected to the second anaerobic degradation cell 34 .

[0044] During the working process, the sewage is first pumped into the first aerobic degradation cell 31 through the sewage inlet pipe, and passes through the ecological sludge (ecological sludge is the ecological sludge commonly used in the existing sewage treatment process, and the ecological sludge contains microorganisms that degrade sewage) in the aerobic environment of the first aerobic degradation cell 31.

[0045] After a period of treatment, as the microbial degradation slows down, the sewage in the first aerobic degradation cell 31 is pumped into the second aerobic degradation cell 32 for further degradation. This method ensures that the microorganisms in the ecological sludge maintain high degradation activity during microbial degradation.

[0046] Similarly, after aerobic degradation is completed, the waste can be discharged to the next process after the waste is degraded through the first anaerobic degradation cell 33 and the second anaerobic degradation cell 34.

[0047] Through the above method, during the degradation process, once the microbial degradation activity decreases (microbial degradation is related to the pollution intensity of sewage), the sewage can be immediately transferred to an idle degradation cell with high activity to continue to maintain high degradation activity.

[0048] In this way, the efficiency and effect of microbial degradation of sewage can be improved.

[0049] Example 2

[0050] like Figure 1-5As shown, based on the structure of Example 1, the present embodiment has an ecological sludge assembly 4 fixedly connected to the aerobic degradation cell and the anaerobic degradation cell respectively. The ecological sludge assembly 4 includes a crossbeam 41 installed at the upper end of the aeration cell, and a plurality of ecological tubes 42 are fixedly connected to the bottom of the crossbeam 41. The ecological tubes 42 are provided with a plurality of through holes 421, and the ecological tubes 42 are filled with ecological sludge.

[0051] Specifically, the top of the ecological tube 42 is connected to a feed pipe 422 (ecological sludge is pumped into the feed pipe 422 ), and a fastening screw 411 fastened to the crossbeam 41 is threadedly connected to the pipe mouth of the feed pipe 422 .

[0052] During operation, microbial degradation activity primarily occurs around the ecological tube 42, thereby resolving the technical drawback of conventional sewage tanks where the ecological sludge cannot be quickly and effectively replaced once its activity decreases. During operation, when the activity of the degraded sludge decreases, the ecological sludge can be quickly replaced.

[0053] To trap sludge, a cylindrical filter 431 is fixedly attached to the outer wall of the eco-tube 42. This filter 431 includes an annular seat 43 fixedly attached to the upper and lower sides of the eco-tube 42, between which the cylindrical filter 431 is fixedly attached. The center of the annular seat 43 has a threaded hole (correspondingly, the outer wall of the eco-tube 42 has an external threaded structure); the annular seat 43 is threadedly connected to the eco-tube 42.

[0054] Under the above-mentioned method, a large amount of sludge can be intercepted by the filter, thereby reducing the dispersion of sludge into the sewage, which makes the degradation cell difficult to clean.

[0055] Example 3

[0056] like Figure 1-5 As shown, based on the structure of Example 2, in the aerobic degradation process, in order to provide oxygen for microorganisms, the sewage biodegradation device further includes an aeration mechanism 2 arranged in the aerobic degradation cell.

[0057] Specifically, the aeration mechanism 2 includes a plurality of arc-shaped aeration pipes 21 spanning between the first aerobic degradation cell 31 and the second aerobic degradation cell 32. The bottoms of the arc-shaped aeration pipes 21 are respectively connected with horizontal connecting pipes 23. According to the conventional aeration method disclosed in the prior art, the air inlet end of the above-mentioned horizontal connecting pipes 23 is connected with an aeration fan (specifically, the horizontal connecting pipes pass through the side walls of the corresponding first aerobic degradation cell 31 and the second aerobic degradation cell 32, and are assembled and connected to the aeration fan. The aeration fan is an aerator conventionally used in the sewage treatment process in the prior art); a plurality of aeration holes 221 are opened on the arc-shaped aeration pipes 21.

[0058] The arc-shaped aeration pipe 21 includes an arc-shaped portion, and vertical aeration pipe portions 22 are integrally formed at both ends of the arc-shaped portion and are respectively located in the first aerobic degradation cell 31 and the second aerobic degradation cell 32; the vertical aeration pipe portion 22 is provided with a plurality of aeration holes 221 spaced apart from each other.

[0059] During operation, when the aeration fan (not shown) is working, the aeration gas bursts out from the vertical aeration pipe portion 22 and the aeration holes and enters into the sewage to perform aeration treatment on the sewage.

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
