Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a vertical oxidation ditch micro-power water treatment system, which is provided with an oxidationditch area and a sedimentation tank area so as to achieve aeration circulation treatment and standing sedimentation simultaneously, and effectively improves the sewage treatment efficiency; a partition plate extending in the vertical direction is adopted to divide the oxidation ditch area into an aerobic zone and an anoxic zone of which the bottoms are communicated; wherein an aeration pipe for providing oxygen is arranged at the bottom of the aerobic zone, when a water inlet pipe and the aeration pipe work, liquid in the aerobic zone is driven by oxygen potential energy to surge upwards andgo over the upper end of the partition plate to converge in the anoxic zone to circulate, and then an oxidation ditch circularly flows in a vertical plane is formed. According to the present invention, the circulation power of the oxidation ditch comes from the residual energy of the aerated gas, so that the power equipment required by the circulation is eliminated, and the advantages of energy saving, environmental protection, small space occupation and compact structure are achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a microdynamic water treatment system of a vertical oxidation ditch. Background technique [0002] Oxidation ditch is a kind of activated sludge treatment system. Its aeration tank is a closed ditch type, so it is different from the traditional activated sludge method in terms of hydraulic flow. It is a circulating flow aeration ditch connected end to end. Also known as circulating aeration tank. There are many forms of oxidation ditch, but they are all connected end to end when viewed from the plane. For example, Carrousel Oxidation Ditch, Auberi Oxidation Ditch, the advantage of the planar oxidation ditch is that the existing propulsion equipment can ensure the smooth progress of the circulation. In large-scale sewage stations, the plane size is far greater than the water depth. [0003] At present, most of the oxidation ditch is a planar oxidati...
