[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in construction, agriculture, energy, environmental protection, urban landscape and other fields. When treating sewage, filtration equipment is used to filter the sewage.

[0003] Although the existing sewage treatment device can filter sewage during use, it still has some shortcomings during use. For example, it is not convenient to discharge the mud during use, causing the mud to accumulate inside the filter equipment, affecting the filtering effect.

[0004] The existing patent (Announcement No.: CN219646798U) is a filtering device for industrial wastewater treatment. This device can filter the sewage by providing a filter screen so that the sewage can be discharged. The motor can drive the threaded rod to rotate. The threaded connection between the threaded rod and the threaded hole is used to make the threaded rod drive the control plate to move, and then the control plate drives the scraper to move, so that the scraper can push the mud intercepted on the filter screen. The inclined plate can be used to discharge the mud from the slag discharge port when the scraper moves upward, thereby solving the problem of inconvenience in discharging the mud in the process, causing the mud to accumulate inside the filtering equipment and affecting the filtering effect.

[0005] In response to the above problems, existing patents have provided solutions. However, the existing filtering equipment is not convenient for discharging large-scale waste materials that have been initially filtered out during filtering. As a result, when there is too much large-scale waste material in the filtering equipment, workers are required to manually salvage the accumulated large-scale waste material, which increases labor and increases the limitations of the use of the filtering equipment.

The salvaging assembly 2 can be provided to perform preliminary filtration on the discharged sewage, and after it is powered on and started, it can rotate, and during the rotation process, the large-scale waste materials preliminarily filtered out can be transported out, thereby eliminating the need for staff to manually salvage the accumulated large-scale waste materials, thereby reducing labor and increasing the limitations of the use of the filtering equipment. The filtering assembly 3 can be provided to perform adsorption filtration on the sewage after the preliminary filtration, thereby improving the sewage filtration quality.

[0031] Specifically, such as Figure 5 As shown, the filter assembly 3 includes a filter box 301, and a guide groove 302 is opened on the left side of the top of the filter box 301. The guide groove 302 and the inner wall of the filter box 301 are fixedly connected to the surface of the trapezoidal box body 201. A servo motor 303 is fixedly connected to the right side of the filter box 301. The output end of the servo motor 303 passes through the filter box 301 and the trapezoidal box body 201, and is fixedly connected to the side opposite to the auger 205. The inner wall of the filter box 301 is fixedly connected to an adsorption frame 304, and the inner wall of the adsorption frame 304 is provided with an activated carbon adsorption layer 305 used therewith.

[0032] Specifically, such as Figure 5 As shown, the bottom of the filter box 301 is fixedly connected with a support rod 4 , and there are four support rods 4 in total, and the four support rods 4 are evenly distributed on both sides of the bottom of the filter box 301 .

[0033] Specifically, such as Figure 5 As shown, the left side of the filter box 301 is connected to a discharge pipe 5 , and a valve 6 for use therewith is provided on the surface of the discharge pipe 5 .

[0034] In this embodiment: by setting the support rod 4, it can support the filter box 301, thereby preventing the filter box 301 from contacting the ground and causing the filter box 301 to be corroded, and by setting the discharge pipe 5 and the valve 6, the discharge pipe 5 can discharge the filtered sewage, and under the setting of the valve 6, it is convenient to open and close the discharge pipe 5.

[0041] Working principle: First, connect the connecting pipe 1 to the required sewage discharge equipment, and then after the sewage enters the trapezoidal box 201, the servo motor 303 can be started. After the servo motor 303 is started, the auger 205 can be driven to rotate under the fixation of the filter box 301, and then the rotation of the auger 205 can be used to transport the large-scale waste filtered out from the filter screen 204 fixed on the filter frame 203, and the filtered sewage passes through the filtration of the filter screen 204 and falls on the activated carbon adsorption layer 305 in the adsorption frame 304. Then, through the adsorption and filtration of the activated carbon adsorption layer 305, the filtration quality of the sewage is increased, and when the waste is transported by the auger 205, it can fall on the guide hopper 8 through the discharge port 7, and then, through the guidance of the guide hopper 8, the waste can be discharged to the desired position. After the sewage is filtered, the valve 6 can be opened to allow the discharge pipe 5 to discharge the filtered sewage into the desired container.
