[0002] With the rapid increase of urban population in my country, more and more nitrogen and phosphorus nutrients are discharged into water bodies, and the control of nitrogen and phosphorus is an important control target for urban sewage discharge and water environment protection.

[0003] In the process of denitrification and dephosphorization of sewage, since the sewage contains a large amount of nitrogen, phosphorus and other substances, foam will float on the surface of the sewage during flow treatment. Most of the existing defoaming treatments for sewage are carried out by adding agents to reduce the generation of bubbles. However, since most of the staff pour the defoaming agent in one place of the pool, the agent content in other parts of the pool is too low and the pouring range is too small, resulting in the agent not being able to be evenly dispersed, reducing the efficiency of sewage purification treatment. Therefore, a solidified microbial sewage treatment device for denitrification and dephosphorization is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a solidified microbial sewage treatment device for nitrogen and phosphorus removal, comprising a box body 1, an electric telescopic rod 3 is fixedly connected to the surface of the box body 1, the output end of the electric telescopic rod 3 penetrates into the interior of the box body 1, and the output end of the electric telescopic rod 3 is slidably connected to the interior of the box body 1, a sliding pipe 4 is slidably connected to the interior of the box body 1, a spraying pipe 13 is fixedly connected to the surface of the sliding pipe 4, and spraying holes 17 arranged equidistantly are provided on the surface of the spraying pipe 13, the surface of the sliding pipe 4 is fixedly connected to the output end of the electric telescopic rod 3, a shell 5 is fixedly connected to the surface of the sliding pipe 4, a medicine storage box 7 is fixedly connected to the surface of the shell 5, a feed hopper 8 is fixedly connected to the surface of the medicine storage box 7, a connecting pipe 6 is fixedly connected to the surface of the feed hopper 8, and the end of the connecting pipe 6 away from the medicine storage box 7 is fixedly connected to the sliding pipe 4.

[0024] A pressure pump is provided inside the medicine storage box 7, and the water outlet of the pressure pump is fixedly connected to the connecting pipe 6. The pressure pump is an existing device, so no further explanation will be given.

[0025] When the electric telescopic rod 3 is started, the output end of the electric telescopic rod 3 pushes the sliding rod 14 to move, and the sliding tube 4 drives the shell 5 and the medicine storage box 7 to move. At the same time, the pressure pump inside the medicine storage box 7 is started, so that the pressure pump starts to send the medicine inside the medicine storage box 7 into the inside of the connecting tube 6, and then the medicine enters the inside of the sliding tube 4 through the inside of the connecting tube 6, so that the medicine enters the inside of the spraying tube 13, and finally the medicine is sprayed out from the spraying hole 17 under the push of the rear medicine. In the process of the movement of the device, through the action of the pressure pump, the medicine is continuously sprinkled into the sewage during the movement, and the sewage inside the box 1 is evenly sprayed, avoiding the direct fall of the medicine into the sewage, so that the concentration of the medicine at the falling place is higher, while the concentration at other positions is lower, so that the medicine is evenly distributed in the box 1, so that the sewage can be fully in contact with the medicine, thereby improving the sewage treatment efficiency, and at the same time, the spraying tube 13 moves back and forth to stir the water flow, so that the medicine can be better mixed with the sewage, further increasing the use effect of the device.

[0026] A limiting groove 10 is opened inside the box body 1, and a limiting rod 11 is fixedly connected to the lower end of the sliding tube 4. The surface of the limiting rod 11 is slidably connected to the inside of the limiting groove 10. Then, by setting the limiting groove 10 and the limiting rod 11, the sliding of the sliding tube 4 is restricted, thereby avoiding the sliding tube 4 from tilting during the sliding process.

[0027] The shell 5 is slidably connected to a baffle 9, and a slide groove 15 is slidably opened on the inner wall of the baffle 9. The shell 5 is slidably connected to an extrusion plate 18. The surface of the extrusion plate 18 is slidably connected to the surface of the baffle 9, and the inner wall of the slide groove 15 is slidably connected to the surface of the extrusion plate 18. A spring 16 is fixedly connected to the inner wall of the slide groove 15, and one end of the spring 16 away from the slide groove 15 is fixedly connected to the extrusion plate 18. A card plate 12 is fixedly connected to the inner wall of the box body 1, and the card plate 12 is serrated. The shell 5 is slidably connected to a sliding rod 14, and the lower end of the sliding rod 14 contacts the surface of the card plate 12. One end of the sliding rod 14 located inside the shell 5 is fixedly connected to the extrusion plate 18, and through holes 2 are opened on the bottom of the shell 5 and the surface of the extrusion plate 18.

[0028] When the sliding tube 4 moves, the sliding tube 4 drives the shell 5 to move, and the shell 5 drives the sliding rod 14 to move. As the sliding tube 4 moves, the foam floating on the sewage surface will enter the interior of the shell 5, and under the action of gravity, the sliding rod 14 will stick to the surface of the card plate 12, and because the card plate 12 is serrated, the sliding rod 14 will continue to move up and down. When the sliding rod 14 moves up, the sliding rod 14 drives the extrusion plate 18 to move, and the extrusion plate 18 drives the baffle 9 to move. When the baffle 9 contacts the top of the inner wall of the shell 5, the extrusion plate 18 will continue to slide under the setting of the slide groove 15 to squeeze and crush the foam falling on the surface of the extrusion plate 18, and when the subsequent sliding rod 14 moves downward with the extrusion plate 18, the extrusion plate 18 drives the baffle 9 to move to squeeze the foam entering the bottom of the extrusion plate 18, and the foam is squeezed and crushed by starting the electric telescopic rod 3. At the same time, the broken bubbles will return to the sewage through the setting of the through hole 2 to react again, further improving the use effect of the device.

[0029] Working principle: the electric telescopic rod 3 is started, and the output end of the electric telescopic rod 3 pushes the sliding tube 4, the sliding tube 4, the shell 5, and the medicine storage box 7 to move. At the same time, the pressure pump inside the medicine storage box 7 is started, so that the pressure pump starts to send the medicine inside the medicine storage box 7 into the inside of the spray pipe 13, and finally the medicine is sprayed out from the spray hole 17 under the push of the rear medicine.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
