Treatment and processing system for domestic sewage

Abstract

The invention discloses a treatment and processing system for domestic sewage. The system comprises a sedimentation pool and a mud scraping device arranged in the sedimentation pool, wherein the mud scraping device comprises a rotating element, a support element and a plurality of mud scraping components; the support element is connected with the rotating element; the mud scraping components are arranged on the support element at intervals; each mud scraping component comprises a mud scraping plate and a mud scraping element; the mud scraping element is detachably connected with the mud scraping plate through a connecting component; a water inlet pipeline is arranged at the upper part of the sedimentation pool; a flow baffle device used for reducing the impact force on the water body in the sedimentation pool during the water inlet through the water inlet pipeline is arranged on the water inlet pipeline. Through the arrangement of the flow baffle device, the water flow speed of the water inlet pipeline during the water outlet can be effectively decelerated, so that precipitates in the pool body are prevented from being flushed up again; water discharged out from the water collecting groove always maintain the clear state; the water quality of the outlet water is ensured.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a treatment and processing system for domestic sewage. Background technique [0002] There are a large amount of solid matter in domestic sewage, so in the sewage treatment process, the solid matter in the domestic sewage needs to be settled first, the impurities in the sewage settle to the bottom of the pool, and the upper clear water is collected by the upper sump Exhaust outward. However, under this structure, the water in the pool body is directly inflowed from the side through the water inlet pipe, and the water flow is relatively large when entering the water, so it is easy to muddy the water in the original pool body, thus making the sediment deposited on the bottom of the pool If it is turned again, the water in the pool becomes turbid, which in turn affects the quality of the effluent. Contents of the invention [0003] In order to overcome the d...
