Embodiment Construction

[0031] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] figure 1 It is a schematic diagram of equipment connection of the present invention.

[0033] Such as figure 1 As shown, the present invention provides an italic type oxidation ditch, mainly comprising: aerobic pool 1-12 connected in series, facultative oxygen pool 1-13, anaerobic pool 1-14, anoxic pool 1-15, secondary sedimentation Pool 1-9 and clear water pool 1-10; described aerobic pool 1-12, facultative oxygen pool 1-13, anaerobic pool 1-14, anoxic pool 1-15, secondary sedimentation pool 1-9 and clear water Pools 1-10 are combined to form an italic oxidation ditch.

[0034] The italic oxidation ditch passes through three arc-shaped diversion walls 1-3, three linear diversion walls 1-4, one fixed overflow weir 1-7 and one mobile overflow weir 1-8 It is divided into aerobic pool 1-12, facultative pool 1-13, anaerobic pool 1-14, anoxic pool ...

Abstract

The invention discloses an inclined oxidation ditch. The inclined oxidation ditch mainly comprises an aerobic tank, a facultative tank, an anaerobic tank, an anoxic tank, a secondary sedimentation tank and a clean water tank, which are sequentially connected in series. The inclined oxidation ditch is divided into the aerobic tank, the facultative tank, the anaerobic tank, the anoxic tank, the secondary sedimentation tank and the clean water tank through three circular arc flow guide walls, three linear flow guide walls, a fixed overflow weir and a moving overflow weir; two rotating brush aeration machines are arranged at the bottoms of the aerobic tank, the facultative tank, the anaerobic tank and the anoxic tank; detachable support pillars are arranged at the bottom of the inclined oxidation ditch. An integrated design is adopted, so that the inclined oxidation ditch can be used flexibly and conveniently, and can be widely used for treating a small amount of domestic sewage.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering wastewater treatment, in particular to an italic oxidation ditch. Background technique [0002] Due to the increasing shortage of water resources, the solution to point source and non-point source pollution has become the theme of water environmental protection, especially for small water pollution sources that are scattered and difficult to collect, and mobile treatment devices are urgently needed to treat them. In the wastewater treatment system, the activated sludge method occupies an indispensable and important position, and the oxidation ditch process is one of the most important treatment processes for the biological treatment of wastewater. [0003] Oxidation ditch process is an activated sludge process in which sewage circulates in a ditch and is aerated through an aeration brush or a turntable. Oxidation ditch process has the advantages of low sludge load, large circula...
