[0002] Wastewater treatment refers to the process of separating pollutants from sewage or converting them into harmless substances through various methods to purify water. In this process, MBBR equipment is required to efficiently treat sewage.

[0003] The common MBBRs in the current domestic market are all overall process modifications, which have the disadvantages of being difficult to modify and being unable to be modified and upgraded in a modular manner. At the same time, for fully loaded sewage treatment plants, there are no conditions for water outages, and it is difficult for the water plant to carry out an overall MBBR transformation. Therefore, it is necessary to propose a new type of MBBR equipment to modularly modify the MBBR of the sewage treatment plant. Summary of the invention

[0004] The purpose of the utility model is to provide a new type of MBBR equipment to solve the problem mentioned in the above background technology that the common MBBRs in the existing domestic market are all overall process transformations, which have the disadvantages of being difficult to transform and being unable to be transformed and upgraded in a modular manner. At the same time, for a fully loaded sewage treatment plant, there is no water outage condition, and it is difficult for the water plant to carry out the overall MBBR transformation.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a new type of MBBR equipment, comprising:

[0009] Furthermore, a suspension rod is fixedly connected to the top of the connecting rod, and both the support rod and the connecting rod are stainless steel square tubes, and there are four support rods in total.

[0010] Furthermore, the method further comprises an auxiliary uniform component;

[0011] The auxiliary uniform assembly also includes a set of connecting blocks, a motor, a crossbar and a set of connecting rings;

[0029] See also Figure 1-Figure 3 As shown, this embodiment is a new type of MBBR equipment, including:

[0030] The sewage treatment component includes a set of support rods 11, connecting rods 12, stainless steel mesh 13 and aeration pipes 14;

[0031] The connecting rod 12 is fixed to the upper and lower sides of the inner side of the supporting rod 11, the stainless steel mesh 13 is fixed between the connecting rod 12 and the inner side of the supporting rod 11 and the top and bottom ends, and the aeration pipe 14 is arranged at the bottom of the stainless steel mesh 13 below;

[0032] The connecting rod 12 and the supporting rod 11 are used to support and connect the stainless steel mesh 13. A mesh box is formed between the stainless steel mesh 13. The mesh box is used to place the filler for sewage treatment. The aeration pipe 14 is used to aerate and transport the filler into the mesh box, so that aeration and water flow give a certain power to the filler in the mesh box, so that the filler is evenly distributed in the mesh box.

[0033] The top of the connecting rod 12 is fixedly connected with a suspension rod 15. The support rods 11 and the connecting rods 12 are both stainless steel square tubes. There are four support rods 11 in total.

[0034] The suspension rod 15 is used for hoisting and moving the components, and the support rod 11 and the connecting rod 12 are both stainless steel square tubes, in order to extend the service life of the device;

[0035] Working principle:

[0036] When in use, the aeration pipe 14 is connected to the internal pipe of the sewage treatment control room, so that the aeration is transported to the mesh box formed by the stainless steel mesh 13 through the aeration pipe 14, so that the aeration and water flow give a certain power to the filler in the mesh box, so that the filler is evenly distributed in the mesh box, ensuring the removal rate of the pollutants by this device;

[0037] When the device is hoisted, the rope can be connected to the hoist rod 15 so that the rope can hoist the component through the hoist rod 15;

[0038] In the above steps, the filler is evenly distributed in the mesh box through the interaction between the aeration pipe 14 and the stainless steel mesh 13.

[0039] See also Figure 1-Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0040] Auxiliary uniform components;

[0041] The auxiliary uniform assembly also includes a set of connecting blocks 21, a motor 22, a crossbar 23 and a set of connecting rings 24;

[0042] The connecting blocks 21 are respectively fixed below the inner side surfaces of the stainless steel nets 13 on both sides, the motor 22 is fixed below the outer side surface of the stainless steel net 13 on one side, the cross bar 23 is rotatably connected between the inner side surfaces of the connecting blocks 21, and the connecting rings 24 are all fixed on the surface of the cross bar 23;

[0043] There are two connecting blocks 21, and the connecting blocks 21 are used for connecting the cross bars 23, and the motor 22 is used to drive the cross bars 23, and the cross bars 23 are used for connecting the connecting rings 24, and the connecting rings 24 are used for connecting the vertical bars 25;

[0044] One end of the crossbar 23 extends to the inside of the output end of the motor 22, and the two are fixedly connected, and a group of vertical bars 25 are fixedly connected to the outside of the connecting ring 24;

[0045] The motor 22 is a special underwater propulsion motor, which is specially designed for underwater environment and has special waterproof and sealing treatment to ensure its efficient and stable operation underwater. The motor 22 controls the crossbar 23 to rotate through the output end, and the vertical rod 25 is used to connect the shovel plate 26 with the connecting ring 24 and the crossbar 23;

[0046] The outer ends of the vertical rods 25 are fixedly connected with shovel plates 26, and the outer ends of the shovel plates 26 are arc-shaped. There are four vertical rods 25 in total.

[0047] The shovel plate 26 is used to rotate and shovel up the filler at the bottom of the net box to prevent part of the filler from accumulating inside the net box during aeration and transportation;

[0048] There are three connecting rings 24, and the outer ends of the shovel plates 26 are closely attached to the inner side of the lower stainless steel mesh 13;

[0049] The outer end of the shovel plate 26 is set in an arc shape and fits with the bottom end of the inner part of the net box, so as to facilitate shoveling the filler accumulated on the bottom surface of the inner part of the net box;

[0050] Working principle:

[0051] When in use, the motor 22 is started, and the motor 22 and the output end drive the crossbar 23 to rotate, and the crossbar 23 drives the surface connecting ring 24 to rotate, so that the crossbar 23 drives the vertical rod 25 and the shovel plate 26 to rotate together through the connecting ring 24. Since the outer ends of the shovel plate 26 are in contact with the inner bottom surface of the net box formed by the stainless steel mesh 13, when the shovel plate 26 rotates, it drives the filler on the inner bottom surface of the net box that is not blown up by aeration to rotate, thereby avoiding that part of the filler is not blown up by aeration, so that the filler is more evenly distributed in the net box;
