Abstract

An aerobic granular sludge treatment facility comprises a rectangular reaction tank and a sewage inlet pipe. The rectangular reaction tank is provided with a partition board and is divided into a water inlet area and a reaction area by the partition board, a water outlet of the sewage inlet pipe is positioned at the bottom of the water inlet area, a plurality of frame screen boards which are approximately parallel to each other are respectively placed in the water inlet area and the reaction area, the partition board is approximately perpendicular to the frame screen boards, a plurality of water inlet holes are disposed on the partition board, aeration heads are arranged at both the bottom of the water inlet area and the bottom of the reaction area, a blowdown pipe is positioned at the bottom of the water inlet area, a siphon decanter is mounted at the tail end of the reaction area, a water inlet end of the siphon decanter is positioned on the upper portion of the tail end of the reaction area, and a water outlet end of the siphon decanter is positioned in a drainage channel. By the aid of the aerobic granular sludge treatment facility, flocculent activated sludge is granulated, treatment efficacy is greatly improved, accordingly, purification efficacy is enhanced, resources and energy are saved, engineering cost and operation cost are reduced by 20% at least, energy consumption is reduced by 10% at least, and sludge treatment and disposal expenses are reduced by about 10%.

Description

technical field [0001] The invention belongs to the fields of urban and rural sewage treatment and industrial waste water treatment, and relates to a sewage treatment structure beneficial to the formation of aerobic granular sludge, in particular to an aerobic granular sludge treatment facility. Background technique [0002] Activated sludge biological treatment technology mainly relies on activated sludge, a microbial floc, to purify sewage. However, the current activated sludge has a low biomass and a small population, resulting in low treatment efficiency and unstable operation. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an aerobic granular sludge treatment facility with high activated sludge biomass, large population, high treatment efficiency and stable operation. The treatment facility has a small volume and low engineering cost. [0004] Another technical problem to be solved by the present invent...
