Abstract

The invention discloses an integrated aerobic granular sludge composite purifier comprising a shell, wherein the shell is sequentially provided with a central reaction cylinder and a downward rotation ring from inside to outside; a cylinder body of the central reaction cylinder is internally provided with a plurality of layers of horizontal reaction cylinder screen plates which are horizontally arranged; the downward rotation ring is internally provided with a plurality of vertical rotation ring screen plates which are vertically arranged along the radial direction; the lower edge of the cylinder body of the central reaction cylinder and the lower edge of the downward rotation ring are respectively provided with an annular microporous aeration pipe; a side wall sediment and water discharging region is arranged between the downward rotation ring and the shell; the lower end of the shell is of a cone; an accumulated sludge sinking hole is formed between the bottom of the central reaction cylinder and the shell; the bottom end of the shell is provided with a conical sludge accumulating region; a sludge discharging pipe is communicated with the conical sludge accumulating region; and a sludge returning pipe is provided with two outlets. By using the integrated aerobic granular sludge composite purifier, the biological purification and treatment of sludge are integrated in one structure and are simultaneously finished, and complex equipment such as an anaerobic tank, an anoxic tank and a secondary sedimentation tank in the prior art are omitted; and the integrated aerobic granular sludge composite purifier has the advantages of saving space and energy and reducing engineering investment and operation expense.

Description

technical field [0001] The invention relates to a sewage treatment facility, which is a high-efficiency sewage treatment facility with multiple uses in one pool, specifically an integrated aerobic granular sludge compound purifier; the invention also relates to the application of an integrated aerobic granular sludge A method for treating sewage with a compound purifier. Background technique [0002] The current various activated sludge biological treatment technologies mainly rely on flocculent activated sludge microorganisms to purify sewage. Due to their low biomass and small population size, the treatment efficiency is not high. If the flocculent sludge can be granulated and the granular sludge is in a strong turbulent state by using fluidization technology, the phase interfaces of water, gas and solid phases will be continuously renewed, the mass transfer will be accelerated, and the high-strength water in the pool will The air shear force keeps the microorganisms in t...
