The microbial material bin is used for storing microorganisms. One end of the microbial material bin is communicated with the conveying and processing module, and the microbial material bin is used for conveying microorganisms into the conveying and processing module. The other end of the conveying and processing module extends away from the microbial material bin. The side wall of the conveying and processing module is a porous structure, and a filter media element is arranged in the conveying and processing module.

[0010] Preferably, the action module is a drawstring, the drawstring extends along the length direction of the porous pipe, and one end of the drawstring is fixed to the end of the porous pipe away from the microbial bin. Pulling the drawstring in the direction close to the microbial bin can drive the porous pipe to be extruded and deformed.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] The object of the present invention is to provide a microbial bed to solve the problems existing in the prior art, achieve self-cleaning of the outer wall of the microbial silo, and also take into account the growth of aerobic colonies and anaerobic colonies.

[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As Figure 1 shown, this embodiment provides a microbial bed, which includes a microbial silo 1, a conveying and treating module 2, and an action module 5. The microbial silo 1 is used to store microorganisms for temporary storage of microorganisms. The microbial silo 1 is connected to one end of the conveying and treating module 2, and the microbial silo 1 is used to convey microorganisms into the conveying and treating module 2. Then the microorganisms enter the conveying and treating module 2 and decompose pollutants in the sewage in the conveying and treating module 2, playing a role in sewage treatment. The other end of the conveying and treating module 2 extends away from the microbial silo 1. The side wall of the conveying and treating module 2 is a porous structure, so that water can enter the interior of the conveying and treating module 2 through the pores, react with the microorganisms in the conveying and treating module 2, and at the same time realize the two-way mass exchange of microorganisms and sewage. A filter element is provided in the conveying and treating module 2, which can enable microorganisms to adhere to the filter element. The action module 5 is connected to the conveying and treating module 2 and can drive the conveying and treating module 2 to deform. Then, with the deformation of the conveying and treating module 2, part of the suspended foreign matters in the water attached to the outer wall of the conveying and treating module 2 can be shaken off. At the same time, with the deformation of the conveying and treating module 2, the water volume in the conveying and treating module 2 can be reduced, and the water fluidity is poor. To a certain extent, an anaerobic environment of the water body can be created, providing a favorable environment for the growth of anaerobic microorganisms. On the other hand, during the process of the conveying and treating module 2 being squeezed and deformed, the water body exchange inside and outside the conveying and treating module 2 will be accelerated, and microorganisms can be released into the water body to a certain extent for the decomposition of pollutants.

[0025] Specifically, the conveying and treating module 2 includes a plurality of porous tubes. One end of each porous tube is connected to the outlet of the microbial silo 1, and the other end of each porous tube extends away from the microbial silo 1. The filter element is installed in each porous tube, and the filter element is arranged evenly and staggeredly along the length direction of the porous tube, so as to increase the sewage treatment area, improve the sewage treatment efficiency and sewage treatment effect.

[0026] The filter element includes a packing carrier 3 and a packing layer 4. The packing carrier 3 is fixed at different positions on the inner wall of the porous tube, and the packing carrier 3 is used to hold the packing layer 4. The packing layer 4 is limited and fixed by the packing carrier 3 to prevent the accumulation of the packing layer 4 from affecting the adhesion of microorganisms.

[0027] The packing carrier 3 is a mesh bag, which can not only hold the packing layer 4, but also does not affect the entry of microorganisms into the mesh bag and their attachment to the surface of the packing layer 4.

[0028] The packing layer 4 is formed by volcanic rock packing, and those skilled in the art can also make adaptive changes to the specific material of the packing layer 4 according to actual needs.

[0029] The action module 5 is a pull rope, which extends along the length direction of the porous pipe, and one end of the pull rope is fixed at the end of the porous pipe far from the microbial bin 1. When the pull rope is pulled towards the microbial bin 1, it can drive one end of the porous pipe to move towards the other end, thereby causing the porous pipe to be squeezed and deformed. The pull rope can be manually controlled or automatically controlled through a transmission structure. Those skilled in the art can also select other types of action modules 5 according to actual needs.

[0030] The porous pipe is made of soft plastic and can be smoothly squeezed and deformed.

[0031] As another embodiment, the porous pipe is a telescopic pipe, and the telescopic pipe includes multiple pipe units with different pipe diameters. The adjacent pipe units are slidably connected, so that the adjacent pipe units can move towards each other or away from each other under the drive of the pull rope to achieve overall telescoping, and the adjacent pipe units can be limited to each other to prevent them from coming out. Furthermore, through the movement of each pipe unit, the cleaning of the pipe walls of the adjacent pipe units can be realized. In order to ensure the smooth telescoping of the telescopic pipe, the pull rope can also be replaced with other structures, such as an electric push rod, etc.

[0032] This embodiment further includes a feeder, a water quality sensor 6 and a controller. There is a through hole on the microbial bin 1 for connecting and transporting the treatment module 2. The feeder is installed at the microbial bin 1, and the feeder is used to control the opening and closing of the through hole to realize the control of whether to supplement microorganisms into the transportation and treatment module 2; the water quality sensor 6 is installed at the end of the transportation and treatment module 2, and the water quality sensor 6 is used to monitor the water quality. The water quality sensor 6 is electrically connected to the controller, and the controller can control the opening and closing of the feeder according to the water quality value detected by the water quality sensor 6, and control the action frequency of the action module 5, and finally realize the linkage of the bacterial liquid transportation by monitoring the water quality change. For example, when the water quality sensor 6 detects that the water quality exceeds the set limit value, the feeder can be controlled to open to increase the bacterial liquid transportation, and the action frequency of the action module 5 can be controlled to control the mechanical movement contraction frequency of the transportation and treatment module 2.

[0033] The feeder is a control valve and can be manually controlled or automatically controlled.

[0034] This embodiment further includes an outer frame. The microbial bin 1, the transportation and treatment module 2 and the action module 5 are all installed in the outer frame, which plays a supporting role for the overall structure. At the same time, the angle of attack of the overall structure can also be realized by the rotation of the outer frame.

[0035] In the present invention, specific examples are used to illustrate the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
