Integrated biological and ecological cooperative sewage treatment method and reactor

Abstract

The invention discloses an integrated biological and ecological cooperative sewage treatment reactor. The reactor comprises a biological treatment tank, an ecological treatment tank and a disinfection contact tank, wherein separation walls are vertically arranged in a biological treatment tank body and separate the tank body into a plurality of grids; a center grid is used as a blower chamber, and other grids are used as biological tanks provided with suspension stuffing, and the bottom of each tank is provided with a microporous aeration device and a sludge discharge pipe; the biological treatment tank and the ecological treatment tank are connected in series for operation and are separated by a vertically arranged separation wall into two grids; iron-rich stuffing is arranged and aquatic plants are planted in each grid which is also provided with a collector pipe connected with the disinfection contact tank; deflection and guiding separation walls are arranged in the disinfection contact tank to prolong the disinfection contact time; a drain pipe is arranged in a disinfection contact area; and the treated sewage is drained into water bodies nearby. The invention has the advantages of strong shockproof loading capacity, high treatment efficiency, low operation energy consumption, small remaining sludge amount, short process, small floor area, little investment, convenient management, and the like.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to an integrated bio-ecological collaborative sewage treatment reactor. Background technique [0002] Conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation and management, making it difficult to promote them in small towns. In recent years, reactor technology for small town sewage treatment has developed rapidly, such as CN2811278Y "six-dimensional three-phase biological treatment process device", CN1552644 "a small town sewage treatment process" and CN2780751 "baffled wetland filter + lateral subsurface flow wetland bed sewage treatment system" and so on, the first two are bioreactors, which are different from the biological and ecological synergistic treatment of this reactor. In order to achieve higher treatment efficiency, the process flow is longer and the structure...

[0002] Conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation and management, making it difficult to promote them in small towns

In recent years, reactor technology for small town sewage treatment has developed rapidly, such as CN2811278Y "six-dimensional three-phase biological treatment process device", CN1552644 "a small town sewage treatment process" and CN2780751 "baffled wetland filter + lateral subsurface flow wetland bed sewage treatment system" and so on, the first two are bioreactors, which are different from the biological and ecological synergistic treatment of this reactor. In order to achieve higher treatment efficiency, the process flow is longer and the structure is relatively It is complex and consumes a lot of energy, which is not conducive to the operation and management of small town sewage treatment reactors; the latter is a continuous flow artificial wetland treatment system, which is quite different from the intermittent flow ecological treatment pool in this reactor. It adopts the sequence batch operation mode and has the functions of high-efficiency filtration and sedimentation area and phosphorus and nitrogen removal.

In addition, the latter has the problem of a large footprint

However, this ecological treatment pool has high efficiency and a small footprint, and there are no reports about integrated bio-ecological synergistic sewage treatment reactors at home and abroad.
