As shown in fig. 1-3, a vertical oxidation ditch comprises a cylindrical frame 1 and an oxidation ditch body 2 arranged in the frame 1, wherein the oxidation ditch body 2 is arranged in a downward spiral and closed structure, an oxidation ditch body inlet 21 is positioned at the top of the spiral structure, and an oxidation ditch body outlet 22 is positioned at the top of the spiral structure; therefore, the sewage can flow downwards in a spiral mode under the action of gravity after entering the oxidation ditch body 2, and related equipment such as a flow impeller and the like is not needed, so that the energy consumption is reduced, and the energy conservation and emission reduction are facilitated; meanwhile, the space in the vertical direction is expanded due to the downward spiral arrangement, and the occupied area is greatly reduced under the condition of the same flow compared with that of a conventional oxidation ditch.
The cylindrical frame 1 and the oxidation ditch body 2 are made of glass fiber reinforced plastics; glass Fiber Reinforced Plastic (FRP), i.e., fiber reinforced plastic, is a composite material of unsaturated polyester, epoxy resin and phenolic resin matrix reinforced by glass fiber; compared with the traditional oxidation ditch material, the material has the advantages of good chemical stability, corrosion resistance, high and low temperature resistance, non-conductivity, light weight, high strength and the like; the oxidation ditch adopting the material also has the advantages of high strength and light weight, so that the flexibility of building and applying the oxidation ditch is greatly increased. The glass fiber reinforced plastic adopted by the embodiment is epoxy resin-based glass fiber reinforced plastic, has higher hardness and stronger strength compared with other glass fiber reinforced plastics, and is more suitable for the oxidation ditch of a vertical structure.
In the embodiment, the oxidation ditch body 2 is arranged to circle for three circles, the tracks of the oxidation ditch body in each circle are the same, and the projections of the tracks on the horizontal plane are all oval. The reason for the oval shape is that the flow of the sewage is smoother and less affected by the centrifugal force than the circular or other shapes.
The oxidation ditch body 2 is provided with a plurality of aeration heads 23 at the lower two weeks, namely the downstream of the oxidation ditch body 2. Thus, an anaerobic zone is formed upstream of the oxidation ditch body 2 and an oxygen-rich zone is formed downstream thereof. By means of the anaerobic and aerobic combined mode, organic components and oil substances in the sewage can be removed more effectively, and the purification effect and the purification efficiency of the sewage are improved.
