Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to MBBR integrated sewage treatment equipment. Background Art

[0002] MBBR refers to the use of new suspended fillers to allow microorganisms to attach to the carrier. The suspended carrier moves freely in the reactor with the swirling development of the mixed liquid, providing a constantly updated and sufficient biological interface, thereby achieving better sewage treatment effects. In the reactor, the filler can move with the water and gradually grow a biofilm on its surface. The microorganisms on the biofilm use the organic matter in the sewage for metabolism, thereby achieving the purpose of removing organic pollutants in the water.

[0003] When using MBBR technology to treat sewage, after the sewage treatment is completed, it is necessary to use a filter to separate the suspended carriers and impurities in the sewage from the sewage. This process can easily cause the impurities and carriers to block the filter, affecting the filtering effect of the sewage. At the same time, when the filter is completely blocked, the water level above the filter continues to rise, causing sewage overflow, and some impurities and carriers in the sewage may pass through the filter due to their small volume, resulting in poor filtering effect of impurities and carriers in the sewage. Therefore, it is necessary to design an MBBR integrated sewage treatment equipment to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and the proposed MBBR integrated sewage treatment equipment can filter the sewage at least twice through the arrangement of three filter screens, and through the arrangement of vertical plates and inclined plates, even when the filter screen is blocked, it can still achieve the effect of overflow filtration, so that the sewage can continue to be treated even if the filter screen is not replaced in time after being blocked, and at the same time, through the operation of the reciprocating screw, the sewage can be evenly sprayed on the filter screen and flow, so that impurities and carriers will not accumulate in one place, and the filter screen can be easily replaced.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 The MBBR integrated sewage treatment equipment comprises a box body 1, the inner top of the box body 1 is provided with a through opening, the front side of the box body 1 is rotatably connected with a sliding door 2 through a hinge, the front side of the sliding door 2 is provided with a handle, three filter screens 8 are arranged in the box body 1, and the three filter screens 8 are all placed obliquely, and the inner wall of the rear side of the box body 1 is rotatably connected with two reciprocating screw rods 12, and the two reciprocating screw rods 12 are both threadedly connected with moving blocks 14, and the right sides of the two moving blocks 14 are provided with water outlet pipes 15, and the left side of the box body 1 is provided with a three-way pipe 4, and the three-way pipe 4 is connected with the two water outlet pipes 15 through a hose 16, and a driving motor 5 is installed on the rear side of the box body 1, and the output shaft end of the driving motor 5 is fixedly connected to the reciprocating screw rod 12 located on the upper side, and the two reciprocating screw rods 12 are connected by transmission assembly 6, and the bottom space of the box body 1 is connected with the outside through a drain pipe 7, and the transmission assembly 6 includes a transmission wheel arranged on the two reciprocating screw rods 12, and the two transmission wheels are connected by transmission belt transmission.

[0023] Among them, two guide rods 13 are fixedly connected to the inner wall of the rear side of the box body 1. The two guide rods 13 pass through the corresponding moving blocks 14. The two moving blocks 14 are slidably connected to the corresponding guide rods 13.

[0024] The upper ends of the three filter screens 8 are fixedly connected to the vertical plates 11 , and the right inner wall of the box body 1 is fixedly connected to a plurality of inclined plates 3 .

[0025] The lower ends of the three filter screens 8 are fixedly connected with fixed blocks 9, and the multiple fixed blocks 9 are provided with round openings. The rear side of the box body 1 is fixedly connected with multiple cross bars 10, and each cross bar 10 passes through the corresponding round opening.

[0026] The functional principle of the utility model can be explained through the following operation mode: the sewage treated with the carrier is injected into the box body 1 through the three-way pipe 4, the driving motor 5 is started, and the sewage treated with the medicine is injected into the box body 1 through the three-way pipe 4, so that the sewage is injected into the box body 1 through the outlet pipe 15, and the operation of the driving motor 5 drives the two moving blocks 14 to move back and forth through the transmission component 6, so that the sewage can be evenly sprayed on the filter screen 8, thereby preventing the impurities and carriers in the sewage from accumulating in one place and affecting the filtering effect of the sewage. At the same time, due to the arrangement of the three filter screens 8, the sewage can be filtered at least twice, thereby improving the filtering effect of the sewage;

[0027] As time goes by, the impurities and carriers on the filter screen 8 continue to increase, which will cause the mesh of the filter screen 8 to be blocked, and the water level on the filter screen 8 will continue to rise. Since the two outlet pipes 15 are arranged downwardly, the impact on the sewage is small. When the water level on the filter screen 8 reaches a certain height, it will flow through the vertical plate 11, so that a certain filtering effect can still be removed.

[0028] When the filter 8 needs to be replaced, the filter 8 can be cleared through the opening on the top of the box body 1 to allow the sewage to be completely discharged, and then the sliding door 2 is opened to remove the filter 8, and the round opening on the new filter 8 is aligned with the cross bar 10 and pushed in.
