Suspension filling clarifier tank

Abstract

The present invention relates to sewage biotreating technology, and is especially one suspended stuffing clarifier for solid-liquid separation of fluent from bioreaction tank to treat sewage biologically in an active sludge process or biomembrane process. The suspended stuffing clarifier consists of one clear water area, one stuffing trapping area, one aerating pipe, one sludge flocculating area,one sludge overflowing area, one fairing area, one sludge concentrating area, one draining pipe and one grating. The suspended stuffing clarifier may be set alone or through combination with bioreaction tank. It has high solid-liquid separation effect, low cost and other advantages.

Description

technical field [0001] The suspended filler clarifier relates to the biological treatment sewage technology, and is applied to the activated sludge method or the biological membrane method sewage biological treatment process to separate the mixed liquid flowing out of the biological reaction tank from solid and liquid. Background technique [0002] The activated sludge or biofilm sewage treatment process system generally consists of a biological reaction tank and a secondary sedimentation tank (referred to as secondary sedimentation tank), of which the secondary sedimentation tank undertakes two functions of effluent clarification and sludge concentration. However, there are many problems in the actual project operation of the secondary sedimentation tank: ①The area is huge: the surface load of the secondary sedimentation tank is generally controlled at 0.6-0.8m 3 / m 2 .h, the area of ​​the entire secondary sedimentation tank area is even close to the biological reaction ta...

Problems solved by technology

However, there are many problems in the actual project operation of the secondary sedimentation tank: ①The area is huge: the surface load of the secondary sedimentation tank is generally controlled at 0.6-0.8m 3 /m 2 .h, the area occupied by the entire secondary settling tank area is even close to that of the biological reaction tank, which limits the potential of the sewage treatment plant to increase the treatment capacity; There is floating mud problem. In some local sewage plants, even during heavy rainfall in the rainy season, sludge loss often o
