A kind of sludge thickening equipment based on sbr treatment process

Abstract

The invention discloses a sludge thickening device based on an SBR treatment process, which includes a sedimentation tank, a mud scraping mechanism and an aeration mechanism; the mud scraping mechanism is installed at the center of the sedimentation tank through a working bridge, and the aeration mechanism is installed at the bottom of the sedimentation tank; The mud scraping mechanism includes driving device 1, rotating main shaft, screw auger and driving device 2; the driving device is installed on the working bridge and connected with the rotating main shaft; the screw auger is parallel to the bottom of the sedimentation tank and connected with the rotating main shaft, and the The driving device 2 for driving its rotation is separately connected to the top; the mud scraper is also connected to the bottom end of the rotating main shaft, and a mud discharge pipe extending out of the sedimentation tank is installed in the center of the bottom of the sedimentation tank; The supporting installation structure that cooperates with it enables the mud scraper to not only move and scrape mud well along the bottom of the pool, but also have a good mud scraping effect, which ensures the mud scraping time of the mud scraper and greatly saves energy consumption. Has good performance.

Description

technical field [0001] The invention relates to a sludge concentration device, in particular to a sludge concentration device based on an SBR treatment process. Background technique [0002] At present, environmental pollution is becoming more and more serious, environmental protection has become a top priority, and effective treatment of sewage is becoming more and more important. Therefore, the use of sewage treatment equipment has also become one of the keys in the construction of sewage treatment plants. Among them, mud scrapers are sewage treatment One of the most commonly used equipment in China, the sludge thickener is mainly used in water treatment systems such as blast furnaces, continuous casting, hot rolling and water plants in the metallurgical industry, or in coal, chemical, building materials, water sources, anhydrous treatment and other industries. Concentration or purification of solid slurry can also be used for concentration and dehydration of concentrate a...

AI Technical Summary

Problems solved by technology

However, in actual use, when the sludge layer of the existing scraper is thick, the scraping effect is not good, and it is easy to cause damage to the scraper and rake frame and cause waste of energy consumption during the use of the equipment , affect the treatment time of sludge and bring inconvenience to sewage treatment
