[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 5 As shown, the existing biofilm includes a traditional biofilm 1 and a groove 2. When in use, the reaction cells are attached to the groove 2, and the cells in the groove 2 can be multiplied. The organic matter, nitrogen, phosphorus and other pollutants in the sewage are adsorbed and biodegraded by the cells in the groove 2.

[0025] However, during the treatment process, the bacteria inside the groove 2 will directly contact the sewage. The fluctuation of the water quality and temperature of the sewage will affect the bacteria in the groove 2, causing the bacteria to fall off and affecting the adhesion rate of the bacteria, resulting in a decrease in the bacteria in the groove 2, affecting the sewage treatment efficiency.

[0026] As a preferred embodiment of the present invention, Figure 2 As shown, this embodiment provides a device for improving the biofilm attachment efficiency, including a protective shell 3, the protective shell 3 includes a high-strength layer 4, the surface of the high-strength layer 4 is coated with a high-temperature resistant layer 5, and the surface of the high-temperature resistant layer 5 is coated with a corrosion-resistant layer 6.

[0027] When the above embodiment is implemented, that is, when sewage is treated, the bacteria inside the groove 2 are protected by the protective shell 3 to prevent the bacteria in the groove 2 from escaping. At the same time, the sewage has an adverse effect on the bacteria in the groove 2. At the same time, the high-strength layer 4 protects the bacteria in the groove 2 through its high-strength characteristics, which can effectively prevent large particles of debris in the sewage from affecting the bacteria. The corrosion-resistant layer 6 plays an anti-corrosion role, which can effectively prevent the protective shell 3 from being damaged by corrosive substances. The high-temperature resistant layer 5 plays a high-temperature resistant role, which can effectively prevent the protective shell 3 from being damaged by high temperature.

[0028] In some embodiments, Figure 3-Figure 6 As shown, this embodiment provides a mounting module 21, including a movable block 9, a surface of the movable block 9 is slidably connected to the first mounting groove 8, a mounting block 10 is welded to the side of the movable block 9 away from the traditional biofilm 1, the top of the mounting block 10 is connected to an L-shaped plate 11 by bolts, a threaded rod 12 is penetrated through the top of the L-shaped plate 11, the bottom of the threaded rod 12 is rotatably connected to an insert block 13, and a slot 15 is provided on the top of the movable block 9.

[0029] In order to facilitate operation, this embodiment can directly pull the movable block 9 to drive the installation block 10 to move, and adjust the position of the installation block 10.

[0031] In order to facilitate operation, the elastic force of the spring 17 in this embodiment provides a thrust to the connecting plate 18. Under the action of the spring 17, the connecting plate 18 and the baffle 19 move up and down, so that the baffle 19 contacts the installed sewage treatment device. The baffle 19 seals the gap, which can effectively prevent the leakage of debris in the sewage.

[0032] In some embodiments, the slide groove, the slider, the turning handle and the guide rod 20.

Through the slide groove and the slider, it is convenient to guide the connecting plate 18, and it is convenient to ensure the stable movement of the connecting plate 18 and the baffle 19.

[0033] When in use, pull the movable block 9 to drive the mounting block 10 to move, adjust the position of the mounting block 10, and after adjusting the mounting block 10 to a suitable position, the threaded rod 12 is rotated to drive the plug block 13 to move up and down, and the plug block 13 passes through the through hole 14 and is inserted into the slot 15.

After installation is completed, the elastic force of the spring 17 provides thrust to the connecting plate 18, and the connecting plate 18 and the baffle 19 are moved up and down under the action of the spring 17. The baffle 19 is in contact with the installed sewage treatment device. The baffle 19 is used to seal the gap, which can effectively prevent the leakage of debris in the sewage. When treating the sewage, the protective shell 3 protects the bacteria inside the groove 2 to prevent the bacteria in the groove 2 from escaping. At the same time, the sewage has an adverse effect on the bacteria in the groove 2. At the same time, the high-strength layer 4 protects the bacteria in the groove 2 through the high-strength characteristics, which can effectively prevent large particles of debris in the sewage from affecting the bacteria. The corrosion-resistant layer 6 plays an anti-corrosion role, which can effectively prevent the protective shell 3 from being damaged by corrosive substances. The high-temperature resistant layer 5 plays a high-temperature resistant role, which can effectively prevent the protective shell 3 from being damaged by high temperature.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
