Abstract

The invention discloses a built-in desilter, which is characterized in that lifting the agitator and its appendixes in the body tank such as a non-corrodible steel body, a sludge scraper, the plastic inclined tube area and a non-corrodible steel water outlet rectangular channel, arranging the mixing agitator in the mixture tank out of the body tank, connecting the sludge screw pump with incurrent siphon and concentrated sludge discharge area using a sludge pipe.

Description

Technical field: [0001] The invention relates to the technical field of sedimentation tanks, in particular to a water treatment tank used for mixed flocculation and sedimentation in conventional treatment in water supply plants and primary treatment in sewage plants. Background technique: [0002] At present, the conventional treatment of waterworks and the primary treatment of sewage plants mostly adopt traditional tank types such as advection sedimentation tanks, mechanical stirring clarifiers, and inclined tube sedimentation tanks. Among them, although the conventional water quality of the advection sedimentation tank can also meet the requirements of the water to be filtered, and it is easy to manage and resistant to impact loads, but it occupies a large area and has a large amount of sludge discharge, and the treatment effect on low-temperature and low-turbidity water is poor; mechanical agitation Although the clarification tank occupies a small area, it is difficult to...
