[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 4 This utility model provides a deep denitrification and desalination wastewater treatment system, which includes as follows: Figure 1 As shown, it includes: a pretreatment unit system, an anaerobic treatment unit device, an A / O--A / O biochemical unit, an ozone catalytic oxidation unit, and a deep biochemical treatment unit;

[0022] Specifically, wastewater first enters the pretreatment unit system, whose main purpose is to remove large particulate matter, suspended solids, and some organic matter from the wastewater to reduce the burden on subsequent treatment processes. After pretreatment, the wastewater enters the anaerobic treatment unit. Anaerobic treatment is a technical process that uses anaerobic microorganisms to decompose and metabolize organic matter in a strictly anaerobic or low-oxygen environment. The A / OA / O biochemical unit achieves effective removal of organic matter, nitrogen, and phosphorus from the wastewater through alternating operation of anoxic and aerobic environments. The ozone catalytic oxidation unit uses the oxidizing properties of ozone to deeply treat the wastewater. Ozone catalytic oxidation technology can completely degrade or transform recalcitrant organic components in wastewater in a short time, thereby achieving the purpose of purifying the water body. The deep biochemical treatment unit is the key link in the final treatment of wastewater, removing residual pollutants from the wastewater and ensuring that the wastewater meets discharge standards or reuse requirements.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The pretreatment unit system includes: a settling device, which includes: a box 1, a partition 12 fixedly connected to the bottom wall of the box 1, a frame 3 slidably connected to the front and rear inner walls of the box 1, a sliding groove provided on the front and rear inner walls of the box 1, the front and rear surfaces of the frame 3 located inside the sliding groove, a filter screen 4 fixedly connected to the side inner wall of the frame 3, an output pipe 7 fixedly connected to the left surface of the box 1, the output pipe 7 communicating with the box 1, a valve 8 provided on the side surface of the output pipe 7, a guide plate 9 fixedly connected to the bottom wall of the box 1, the guide plate 9 located to the left of the partition 12, a brake motor 2 fixedly connected to the front surface of the box 1, a rotating shaft 10 fixedly connected to the output end of the brake motor 2, the rotating shaft 10 penetrating the front surface of the box 1, and a support plate 11 fixedly connected to the side surface of the rotating shaft 10.

[0024] Specifically, under the braking action of the brake motor 2, the support plate 11 is located on the left side of the rotating shaft 10, and together with the partition plate 12, the frame 3 and the filter screen 4, forms a sealed space for wastewater sedimentation. When wastewater is placed in it, under the constraint of gravity and the filter screen 4, the impurities in the wastewater will settle on the upper surface of the support plate 11. The wastewater will enter the left side of the box 1 through the filter screen 4. Since the partition plate 12 divides the box 1 into two spaces, the wastewater after sedimentation and filtration will be located on the left side of the partition plate 12. When it is necessary to discharge wastewater, the valve 8 on the side surface of the output pipe 7 is opened to control the discharge of wastewater. When it is necessary to replace the filter screen 4, it is disassembled and replaced by pulling out the frame 3 inside the slide.

[0025] Reference Figure 1 , Figure 2 and Figure 3A brake motor 2 is fixedly connected to the front surface of the box 1. A rotating shaft 10 is fixedly connected to the output end of the brake motor 2. The rotating shaft 10 passes through the front surface of the box 1. A support plate 11 is fixedly connected to the side surface of the rotating shaft 10. Rotating grooves are provided on the front and rear inner walls of the box 1. The front and rear surfaces of the support plate 11 are located inside the rotating grooves. The rotating shaft 10 and the support plate 11 are located inside the box 1. A collection chamber 5 is slidably connected to the bottom wall of the box 1. A pull ring is fixedly connected to the front surface of the collection chamber 5. The collection chamber 5 is located directly below the support plate 11 and is located to the right of the partition 12, the frame 3, and the filter screen 4. A support column 6 is fixedly connected to the lower surface of the box 1.

[0026] Specifically, the brake motor 2 is started to provide power to drive the rotating shaft 10 to move the support plate 11 downward along the axis of the rotating shaft 10 inside the rotating groove, so that the sediment on the support plate 11 slides into the inside of the collection chamber 5. Then, it rotates in the opposite direction to reset the support plate 11. The collection chamber 5 is easy to disassemble and clean the sediment inside through the pull ring on the front surface. The support column 6 on the lower surface of the box 1 is used to support the box 1 and ensure the stability of the device operation.

[0027] Working principle: Wastewater is placed in a sedimentation space formed by a support plate 11, a partition 12, a frame 3, and a filter screen 4. Under the constraint of gravity and the filter screen 4, impurities in the wastewater will settle on the upper surface of the support plate 11. Wastewater without sedimentation enters the left space of the tank 1 (left side of the partition 12) through the filter screen 4. When the treated wastewater needs to be discharged, the valve 8 on the side surface of the output pipe 7 is opened, and the wastewater discharge is controlled by the guide plate 9. When the filter screen 4 needs to be replaced, it is disassembled and replaced by pulling out the frame 3 inside the slide. After the wastewater has settled, the brake motor 2 is started, driving the rotating shaft 10 to move the support plate 11 downward along the axis of the rotating shaft 10 inside the rotating trough. The sediment on the support plate 11 slides down into the collection chamber 5 under the action of gravity. Then the rotating shaft 10 is rotated in the opposite direction to reset the support plate 11 to the initial position. The collection chamber 5 is disassembled by pulling the ring to clean the sediment inside.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
