[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] Example 1: See Figures 1 to 8 As shown, a movable perforated plate includes a base frame 1, a support frame 2 mounted on the base frame 1, and a perforated plate 3 mounted on the support frame 2. The base frame 1 and the support frame 2 are both hollow structures. The perforated plate 3 has a plurality of water-permeable holes evenly distributed on it. The two ends of the water-permeable holes are respectively connected to the top surface and the bottom surface of the perforated plate.

[0035] There is a frame-shaped spacing 4 between the outer edge of the support frame 2 and the outer edge of the bottom frame 1. A flexible plate 5 is also installed on the outer edge of the top surface of the support frame 2. The inner end of the flexible plate 5 is installed within the frame-shaped spacing 4, and the outer end of the flexible plate 5 is located on the outside of the bottom frame 1.

[0036] Multiple guide wheels 6 are rotatably mounted on the outer edge of the bottom surface of the bottom frame 1, and the outer surface of the guide wheels 6 is located on the outer bottom of the bottom of the bottom frame 1.

[0037] See Figure 7 , 8 As shown, this utility model also provides a multiphase bioreactor, including a box body 7, a chamber 8 inside the box body 7, a fixed perforated plate 9 above the chamber 8, and the aforementioned movable perforated plate 10, which is vertically movable and disposed in the chamber 8 below the fixed perforated plate 9.

[0038] The top of the housing 7 is provided with a vertical drive component 11, which is configured to drive the moving perforated plate 10 to move vertically within the chamber 8.

[0039] The outer surface of the flexible plate 5 abuts against the inner surface of the chamber 8, and the outer surface of the guide wheel 6 is close to or abuts against the inner wall of the chamber 8.

[0040] In the utility model, the sponge filler is placed in the chamber between the fixed hole plate and the movable hole plate, the sponge filler has denitrifying bacteria, under the condition of oxygen deficiency, the denitrifying bacteria multiply in large quantities, can convert nitrate nitrogen in sewage into nitrogen gas and remove, and the purpose of denitrogenation is achieved. In the process of sewage treatment, in the process of denitrogenation of denitrifying bacteria, because the sponge filler is used, it has strong mechanical interception effect, adsorption effect of the surface microorganism of the sponge filler and sticky substance produced in metabolism, so that the SS (suspended matter) of effluent is very low, generally does not exceed 10 mg / L, therefore, the secondary sedimentation tank (secondary sedimentation tank) can be saved, and the capital construction cost is reduced, it can not only denitrogenate, but also effectively remove organic matter and suspended matter in sewage. Because the sponge filter adsorption capacity is limited, after a certain amount of sludge is adsorbed, it cannot be adsorbed any more, therefore, the fixed hole plate and the movable hole plate are arranged, when the sludge needs to be extruded, the vertical driving part drives the movable hole plate to move upwards, the distance between the movable hole plate and the fixed hole plate is reduced, so that the sponge filler is extruded, the sludge in the sponge filler is extruded, after extrusion is completed, the movable hole plate is moved downwards and away from the fixed hole plate, and the original state is restored through the self-restoring force. Because the size of the box body is large, the size of the movable hole plate is also large, the movable hole plate and the box body are made of metal material, it is difficult to guarantee the precision, and the material has self-deformation problem, in the normal mode, a small gap is reserved between the movable hole plate and the box body, so as to prevent the movable hole plate from moving and colliding, jamming and other problems, the size of the sponge filler is small, part of the sponge filler falls downwards to the lower side of the movable hole plate, the sludge in the sponge filler at the lower side cannot be extruded when the movable hole plate moves to extrude the sludge, and the sewage treatment effect is affected.

[0041] Therefore, in the embodiment, in order to increase the strength of the movable hole plate and reduce the strength as much as possible, the bottom frame, the support frame and the hole plate are hollow structures, which are light in weight, good in strength and strong in anti-deformation. At the same time, in order to prevent the edge of the movable hole plate from scratching the inner wall of the box, a flexible plate is arranged at the outer edge of the movable hole plate, the flexible plate surrounds the outside of the support frame, the outer surface of the flexible plate abuts against the inner wall of the box, the flexible plate is made of rubber, and the outer surface of the flexible plate is tightly fitted with the inner wall of the box. In this way, even if the machining precision is a little low or the box and the movable hole plate are slightly deformed, the elastic force of the flexible plate can also contact the inner surface of the box, so as to prevent the sponge filler from leaking from the gap between the movable hole plate and the box. Furthermore, the outer surface of the guide wheel is located outside the bottom of the bottom frame, the outer surface of the outer end of the guide wheel is located directly below the flexible plate, and the outer surface is close to the inner wall of the cavity or abuts against the inner surface of the cavity. Due to the precision problem between the movable hole plate and the box, it is difficult to ensure that the outer surface of each guide wheel abuts against the inner wall of the cavity respectively. Therefore, the guide wheel is as close to the inner wall of the cavity as possible, or part of the guide wheel contacts the inner surface of the box, and part of the guide wheel has a gap with the inner wall of the box. In this way, even if there is slight shaking or some deformation during movement, some guide wheels can still contact the inner surface of the cavity, so as to ensure the stability during movement, thereby ensuring the stability and smoothness of the movable hole plate during movement. Moreover, during movement, the guide wheel can also abut against the inner wall of the box, so as to prevent the flexible plate from being deformed too much and causing the outer surface of the bottom frame to slide and contact the box rigidly, and only the guide wheel and the box can be rolled and guided.

[0042] Referring to Figure 3 As shown in the figure, the inner end surface of the flexible plate 5 is in contact with the outer surface of the support frame 2, and the inner end bottom surface of the flexible plate 5 is placed on the top surface of the bottom frame 1 of the frame-shaped spacing 4. The frame-shaped pressing plate 11 is further arranged on the flexible plate 5 in the frame-shaped spacing 4, and the inner end of the flexible plate 5 is limited on the bottom frame 1 by the locking component (not shown in the figure).

[0043] In the embodiment, the flexible plate is always in contact with the inner wall of the box and is in sliding contact, so the flexible plate is prone to wear and other problems. Therefore, in order to facilitate the maintenance and replacement of the flexible plate, the flexible plate is directly placed on the frame-shaped spacing on the top surface of the bottom frame, and then the frame-shaped pressing plate is directly pressed on the flexible plate, and the flexible plate is locked on the bottom frame by the locking component. The movable hole plate is rectangular or square, and the frame-shaped pressing plate is also rectangular or square. The frame-shaped pressing plate can be composed of four plates, and the locking component is a bolt. The bolt is screwed through the flexible plate and the bottom frame, so as to realize the locking and limiting of the flexible plate. When the flexible plate is replaced, the frame-shaped pressing plate is removed, and then the flexible plate can be quickly replaced. Subsequently, the frame-shaped pressing plate can limit the flexible plate on the bottom frame.
