Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically refers to a sewage treatment device for water ecological environment governance. Background Art

[0002] Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. In the work of ecological environment governance, sewage needs to be pretreated before being discharged into external water sources to filter out impurities in the sewage to prevent it from entering the nature and causing pollution.

[0003] When performing water treatment and filtration, it is usually necessary to set up a filter screen to filter impurities in the sewage through the filter screen. For example, the publication (announcement) number: CN220695979U discloses a sewage treatment device for water ecological environment management. The filter screen can be cleaned by a cleaning scraper driven by a servo motor, instead of manually rotating the rotary rod, saving manpower. The impurities cleaned can be discharged through a sewage pipe.

[0004] However, there are some shortcomings in use: the sewage pipe is set on one side of the filter, the filter is in a horizontal state, and the scraper cannot ensure that all impurities on the filter enter the sewage pipe when scraping the filter. Moreover, if there are long debris such as branches in the sewage, it is easy to clog the sewage pipe. Based on this, improvements are needed. Utility Model Content

[0007] Furthermore, the blocking device includes a fixing frame, which is fixed on the side wall of the treatment box, and a cylinder is provided on the fixing frame. A blocking plate is provided at the output end of the cylinder, and a guide rod is provided on the blocking plate. The sewage outlet can be blocked and opened by the blocking plate to prevent sewage from flowing out of the sewage outlet.

[0008] Furthermore, the stirring device includes a motor 1, which is arranged on the side wall of the treatment box. A rotating shaft is provided at the output end of the motor 1, and a stirring plate is provided around the rotating shaft. A through hole is provided on the stirring plate, and the through hole can reduce the resistance of the stirring plate to rotation. The stirring plate can disturb and stir the sewage in the treatment box.

[0009] Preferably, the filter screen is arranged in an inclined shape and is inclined toward the sewage outlet, and the lower end of the filter screen is located at the sewage outlet.

[0010] Preferably, the processing box is provided with a window.

[0011] Preferably, the length of the connecting plate is equal to the width of the filter screen.

[0012] Preferably, a sealing plug is provided on the sealing plate, and the sealing plug is made of rubber material and can be just inserted into the sewage outlet.

[0013] The utility model adopts the above structure to achieve the following beneficial effects:

[0014] 1. The utility model can scrape and brush the debris on the filter screen to the sewage outlet by arranging a sliding scraping and brushing device, and the debris falls into the receiving trough through the sewage outlet for centralized collection, so that the debris on the filter screen can be completely removed, thereby ensuring the filtering efficiency of the filter screen.

[0015] 2. The utility model can achieve the blocking of the sewage outlet by setting a blocking device. When there is no need to clean up the debris, the sewage outlet can be blocked to prevent sewage from flowing out of the sewage outlet. The sewage in the treatment box can be disturbed and stirred under the action of the stirring device, and the addition of flocculants can fully react with the sewage.
