Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] The present invention is a full medium-sized reflux flocculation inclined tube sedimentation tank. As shown in Figure 1, the sedimentation tank mainly includes a mixing mixer 3 arranged in a main tank body 2, a lifting mixer 4, and a stainless steel cylinder attached to the lifting mixer 4 5. In the concentrated mud discharge area 11 at the bottom of the main pool body 2, a mud scraper 6 is installed, a water distribution weir and baffle system 10 located on the upper part of the main pool body 2, and a plastic inclined pipe area connected with the water distribution weir and baffle system 10 8 and a stainless steel water outlet rectangular tank 9, a sludge screw pump 7 is arranged outside the tank, connected to the vicinity of the concentrated sludge discharge area, an annular dosing pipe 15 located at the junction of the water inlet pipe 12 and ...

Abstract

The settling pond features that all the mixing stirrer, the raising stirrer and its stainless steel barrel, the mud scraper, the inclined plastic pipe area and the rectangular water outlet stainless steel tank are located inside the main pond; the sludge pipe communicates the sludge screw pump, the water inlet pipe and the concentrating sludge draining area in the lower part of the main pond; and the chemical adding pipe is set below the mixing stirrer. The present invention has reasonable structure and homogeneous water distribution. The raising stirrer and the sludge screw pump are connected with the frequency varying motor for flexible regulation based on the practical condition to ensure the water effluent quality. The mud scraper can centralize and concentrate sludge. The present invention is suitable for use in water works and sewage yard.

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...
