DETAILED DESCRIPTION

[0030] In order to make the person skilled in the art better understand the technical schemes in the present application, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical schemes in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.

[0031] As Figures 1-5As shown, the utility model discloses an embodiment of a kind of MCHS bioreactor for wastewater treatment, including reactor shell 1, the top of reactor shell 1 is fixedly installed with top plate 3, motor 4 is fixedly installed at the middle position of top plate 3 top, the middle position of reactor shell 1 inside is rotatably installed with shaft 5 by bearing, the output end of motor 4 is fixed with the top of shaft 5 by coupling, and motor 4 can drive shaft 5 to rotate.

[0032] As Figure 2 And Figure 3 As shown, a plurality of mounting seats 501 are arranged on the shaft 5 near the bottom, and a plurality of aeration pipes 7 are detachably fixed on the mounting seats 501. Among them, the aeration pipe 7 can be fixed on the mounting seat 501 by screwing, or can be fixed on the mounting seat 501 by bolts, which can be flexibly detached, and is convenient for replacement and maintenance.

[0033] The bottom of the shaft 5 has a hollow design, which is used as an air flow channel, and a plurality of aeration pipes 7 are connected to the air flow channel. The bottom of the reactor shell 1 is fixedly installed with a gas supply pipe 2, one end of the gas supply pipe 2 is connected to the inside of the air flow channel, and the other end of the gas supply pipe 2 is connected to the air blower. The air blower can inject air into the air flow channel through the gas supply pipe 2, and then the air will enter the inside of the plurality of aeration pipes 7.

[0034] A plurality of aeration pipes 7 are provided with a plurality of aeration openings 701, and the air entering the inside of the aeration pipe 7 can be uniformly released into the water through the aeration openings 701, so as to uniformly aerate the water.

[0035] Specifically, the motor 4 drives the shaft 5 to rotate, so that the aeration pipe 7 can stir the wastewater, thereby performing mechanical aeration. At the same time, the air blower injects air into the air flow channel and the plurality of aeration pipes 7 through the gas supply pipe 2, and the air is released into the water through the aeration openings 701, realizing air blowing aeration. In this way, the aeration pipe 7 is used as a stirring rod, which can realize real-time flushing of the surface of the aeration pipe 7, avoiding the formation of biofilm on the surface of the aeration pipe 7, which causes the aeration openings 701 to be gradually blocked, and combining mechanical aeration with air blowing aeration, which greatly improves the aeration effect.

[0036] It is worth noting that, since the aeration pipe 7 can move dynamically inside the reactor shell 1, the air blowing aeration is more comprehensive and uniform, and there is no dead angle.

[0037] As Figure 2 And Figure 5As shown, the bottom end inside the reactor shell 1 is fixedly installed with a cleaning assembly 8, the cleaning assembly 8 includes a fixed frame 801, the fixed frame 801 is in the shape of "C", the fixed frame 801 is fixedly installed at the bottom end inside the reactor shell 1, the top end and the bottom end inside the fixed frame 801 are fixedly installed with a first cleaning brush 802 and a second cleaning brush 803 respectively, the first cleaning brush 802 and the second cleaning brush 803 are oppositely arranged and are both used for cleaning the surface of the aeration pipe 7.

[0038] Specifically, when the aeration pipe 7 rotates through the inside of the fixed frame 801, the first cleaning brush 802 and the second cleaning brush 803 can clean the surface of the aeration pipe 7 to realize automatic and real-time cleaning of the surface of the aeration pipe 7, so as to ensure that the surface of the aeration pipe 7 will not be fouled or form a biofilm, and ensure efficient aeration.

[0039] As shown in Figure 3 and Figure 4 A plurality of installation rails 9 are welded and fixed on the outer wall of the rotating shaft 5, and a plurality of placement racks 6 are fixedly installed on the plurality of installation rails 9. The plurality of placement racks 6 are used for placing fillers. The placement rack 6 is provided with a plurality of openings 601, which can avoid the placement rack 6 from hindering the contact between the filler and the bubbles, and facilitate the installation of the filler through the openings 601.

[0040] Specifically, the filler needs to be fixed on a special support and placed in water first. At this time, the special support with the filler fixed thereon can be first fixed on the placement rack 6, and then the placement rack 6 can be installed on the installation rail 9, so that the filler can be installed inside the reactor shell 1.

[0041] The installation block 10 is welded and fixed on the placement rack 6 and is in sliding fit with the installation rail 9. The placement rack 6 is slidably installed on the installation rail 9 through the installation block 10. A plurality of preset holes 901 are formed in the installation rail 9, and a pair of fastening bolts 12 are penetrated through the installation block 10. A locking nut 11 is arranged on each of the fastening bolts 12. After the pair of fastening bolts 12 are respectively penetrated through the pair of preset holes 901, the installation block 10 can be fixedly installed on the installation rail 9 by locking the locking nuts 11.

[0042] In addition, the plurality of preset holes 901 are arranged at equal intervals. The installation block 10 can be fixed at different positions of the installation rail 9 through the plurality of preset holes 901 arranged at equal intervals, so that the plurality of placement racks 6 can be installed at different heights, so as to arrange the fillers at different heights inside the reactor shell 1.

[0043] In addition, as shown in Figure 4 The installation rail 9 is provided with a limiting portion 902 for limiting the transverse position of the installation block 10, which facilitates the installation of the placement rack 6.

[0044] Specifically, when laying the filler, first fix the specific support fixed with the filler on the placing rack 6, then slide the mounting block 10 on the placing rack 6 to be assembled on the mounting rail 9, and pass through the corresponding preset hole 901 by the fastening bolt 12, and lock by the locking nut 11, so that the laying of the filler can be completed. Since the installation height position of the placing rack 6 can be flexibly adjusted, the filler can be laid at different height positions inside the reactor shell 1, so as to more uniformly and efficiently degrade the wastewater.

[0045] It is worth noting that the filler is indirectly mounted on the rotating shaft 5, and the filler also rotates with the rotating shaft 5, so that the surface of the filler does not attach too thick biological nests, and the degradation efficiency is ensured.

[0046] The reactor shell 1 is provided with a manhole 101, and the manhole 101 is convenient for workers to observe and record the degradation process and result of the wastewater.

[0048] For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
