Problems solved by technology

[0002] There are a large amount of solid matter in domestic sewage. Therefore, in the sewage treatment process, the solid matter in the domestic sewage needs to be settled first. During the settlement process, the dirt settled at the bottom of the settlement tank needs to be treated. However, in the existing sewage sludge scraping equipment, the scraper is usually a flat plate, and the flat scraper only scrapes the sludge at the bottom of the sedimentation tank. During the scraping process, its resistance is large, and the scraping effect is poor, resulting in the scraping process. Poor efficiency in

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0021] Such as Figure 1-5 Shown, a kind of sewage treatment system comprises settling tank 1 and mud scraping device 2, and described settling tank 1 is a conical tank, and this settling tank 1 is formed by pouring cement; At the bottom of this settling tank 1 There is a row of mud pipes connected to the center, and the mud scraped by the mud scraping device 2 enters into the mud discharge pipe, and then is discharged through the mud discharge pipe. The specific mud discharge pipe mud discharge is the prior art, so it will not be repeated here; The mud scraping device 2 includes a motor 20, a rotating part 21, a support part 22 and a mud scraping part 3. The rotating part 21...

Abstract

The invention discloses a sewage treatment system, comprising a precipitating tank and a mud scraper disposed in the same; the mud scraper includes a rotator, a support connected with the rotator anda plurality of mud scraping parts arranged on the support at intervals; each mud scraping part includes a mud scraping plate and a mud scraping element, the mud scraping element is releasably connected with the mud scraping plate through a connection part; each mud scraping plate is provided with an arc face that is provided with a plurality of ribs. The mud scraping parts are arranged to includethe mud scraping element and the mud scraping plate; one mud scraping element may be fixed to each mud scraping plate; mud is blocked, flowing direction of mud is limited, and mud is accumulated and flows to the center of the precipitating tank; the mud scraping elements are arranged to scrap and remove mud; the mud scraping elements are good in abrasiveness, rarely abrade, have long service lifeand great scraping capacity; the connection parts arranged to mount the mud scraping elements, and accordingly the mud scraping elements are convenient to replace.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] There are a large amount of solid matter in domestic sewage. Therefore, in the sewage treatment process, the solid matter in the domestic sewage needs to be settled first. During the settlement process, the dirt settled at the bottom of the settlement tank needs to be treated. However, in the existing sewage sludge scraping equipment, the scraper is usually a flat plate, and the flat scraper only scrapes the sludge at the bottom of the sedimentation tank. During the scraping process, its resistance is large, and the scraping effect is poor, resulting in the scraping process. Poor efficiency in . Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a sewage treatment system with high working efficiency. [0004] In order to achieve the above object, th...
