Description

Technical Field

[0001] The utility model relates to the field of sludge treatment, in particular to a new type of internal circulation granular sludge anaerobic reactor. Background Technique

[0002] Sludge is the solid precipitate generated by water and the sewage treatment process. Sludge treatment is a process of reducing, stabilizing and rendering harmless the sludge. The higher the degree of sewage treatment, the more sludge residues will be generated and need to be treated. Unless sewage is treated by land treatment or sewage pond treatment, general sewage treatment plants must be equipped with sludge treatment facilities.

[0003] In the prior art, the circulation efficiency of the internal circulation granular sludge anaerobic reactor is too low, resulting in poor maintenance of sludge granulation. There is a lack of promotion of mass transfer for the sludge, which leads to low efficiency and poor maintenance of granulation. Therefore, those skilled in the art provide a new type of internal circulation granular sludge anaerobic reactor to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of internal circulation granular sludge anaerobic reactor to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of internal circulation granular sludge anaerobic reactor, including an anaerobic reactor body. The bottom of the anaerobic reactor body is connected and communicated with a water outlet pipe, and a valve is installed on the water outlet pipe. A sealing disc is fixedly embedded on the inner wall of the anaerobic reactor body. The top of the sealing disc is provided with a water inlet through hole, and a sewage suction pump is connected and communicated with the bottom of the water inlet. A water inlet pipe is connected and communicated with the top of the sealing disc. The top of the anaerobic reactor body is attached with a top cover.

[0006] As a further scheme of the utility model: The top end of the water inlet pipe is connected and communicated with a funnel, and a filter disc is embedded in the funnel.

[0007] As a further scheme of the utility model: The top of the sealing disc is provided with a water outlet through hole, and the water outlet is connected and communicated with the water inlet pipe.

[0008] As a further scheme of the utility model: The top of the top cover is provided with a reserved hole, and the water inlet pipe passes through the reserved hole.

[0009] As a further scheme of the utility model: Two heaters are symmetrically and fixedly connected to the outer wall of the anaerobic reactor body. A plurality of heat conduction rings are vertically arranged on the two heaters, and the heat conduction rings are fixedly embedded on the outer wall of the anaerobic reactor body.

[0010] As a further solution of the present utility model: the bottom inner wall of the anaerobic reactor body is an inclined plane, and the sewage suction pump is located below the sealing disc.

[0011] As a further solution of the present utility model: the top end of the water inlet pipe extends to the top of the anaerobic reactor body, and a plurality of legs are arranged in a circular array at the bottom of the anaerobic reactor body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] The wastewater entering the funnel through the filter disc can be filtered by the filter disc. The water inlet pipe can transport the wastewater to the area below the sealing disc. Moreover, by lifting the filter disc, the mixed liquid and sludge can also be transported to the area below the sealing disc through the water inlet pipe. The wastewater and sludge will be sucked by the sewage suction pump through the water inlet and into the area above the sealing disc. In this way, a strong hydraulic force can be forcibly formed to generate a shear force, thereby promoting mass transfer and maintaining sludge granulation.

[0014] The present utility model is simple to use. The filter disc can filter the wastewater and then transport it to the area below the sealing disc. Through the sewage suction pump, the wastewater and sludge can be repeatedly transported between the area above and below the sealing disc for internal circulation. In this way, through the repeated suction and transportation of the sewage suction pump, a strong hydraulic force is formed to generate a shear force, thereby promoting mass transfer and maintaining the granulation of the sludge.

A sealing disk 13 is fixedly embedded on the inner wall of the anaerobic reactor body 1. A water inlet 12 is opened through the top of the sealing disk 13. A sewage suction pump 14 is connected to the bottom of the water inlet 12. A water inlet pipe 9 is connected to the top of the sealing disk 13. A top cover 7 is attached to the top of the anaerobic reactor body 1.

[0023] In this embodiment, a funnel 8 is connected to the top end of the water inlet pipe 9. A filter disk 10 is embedded in the funnel 8. The wastewater entering the funnel 8 through the filter disk 10 can be filtered by the filter disk 10. The water inlet pipe 9 can transport the wastewater to the area below the sealing disk 13. And by picking up the filter disk 10, the mixture liquid and sludge can also be transported to the area below the sealing disk 13 through the water inlet pipe 9. The wastewater and sludge will be sucked by the sewage suction pump 14 through the water inlet 12 into the area above the sealing disk 13, so as to forcibly form strong hydraulic force to generate shear force.

[0024] In this embodiment, a water outlet 11 is opened through the top of the sealing disk 13, and the water outlet 11 is connected to the water inlet pipe 9.

[0025] In this embodiment, a reserved hole 15 is opened on the top of the top cover 7, and the water inlet pipe 9 passes through the reserved hole 15.

A plurality of heat conduction rings 6 are vertically arranged in an array on the two heaters 5, and the heat conduction rings 6 are fixedly embedded on the outer wall of the anaerobic reactor body 1. By starting the two heaters 5, the plurality of heat conduction rings 6 can be heated. The heat conduction rings 6 will evenly distribute the heat on the anaerobic reactor body 1, so as to accelerate the reaction speed of the content in the anaerobic reactor body 1.

[0027] In this embodiment, the bottom inner wall of the anaerobic reactor body 1 is an inclined surface, and the sewage suction pump 14 is located below the sealing disk 13.

The water inlet pipe 9 can transport the wastewater to the lower area of the sealing disc 13. Moreover, picking up the filter disc 10 can also transport the mixed liquid and sludge to the lower area of the sealing disc 13 through the water inlet pipe 9. The wastewater and sludge will be sucked by the sewage suction pump 14 through the water inlet 12 into the upper area of the sealing disc 13. In this way, a strong hydraulic force is forcibly formed to generate a shear force, thereby promoting mass transfer and maintaining sludge granulation. The top cover 7 covers the top opening of the anaerobic reactor body 1 to prevent sundries from entering the anaerobic reactor body 1 and affecting the use effect of the mixed liquid. Starting the two heaters 5 can heat the plurality of heat conduction rings 6, and the heat conduction rings 6 will evenly distribute the heat on the anaerobic reactor body 1, so as to accelerate the reaction rate of the content in the anaerobic reactor body 1.
