Abstract

The invention discloses a novel integrated oxidation ditch for sewage treatment. The novel integrated oxidation ditch comprises a round secondary sedimentation tank, wherein a round inner ditch is arranged at the periphery of the secondary sedimentation tank; a round outer ditch is arranged at the periphery of the inner ditch; a round middle ditch is arranged between the inner ditch and the outerditch; a ring-shaped water collecting groove is arranged between the secondary sedimentation tank and the inner ditch; a sludge-discharging arrangement structure is arranged in the secondary sedimentation tank; the inner ditch, the middle ditch and the outer ditch are internally and respectively provided with an aeration mechanism; the side walls of the middle ditch and the inner ditch are provided with air pipeline components; a water discharging hopper is arranged between the secondary sedimentation tank and the water collecting groove; sidewalk plate components are arranged above the secondary sedimentation tank, the inner ditch, the middle ditch and the outer ditch; a sludge discharging hopper is arranged in the secondary sedimentation tank. The novel integrated oxidation ditch disclosed by the invention has the beneficial effects that the oxygen-deficit function, anaerobic function, aerobic function, sedimentation function and sludge returning function are integrated, the sewage treating effect is good, the operation is stable, the investment is less, the process flow is simple and the management is convenient.

Description

technical field [0001] The invention relates to a novel integrated oxidation ditch for sewage treatment, belonging to the technical field of sewage treatment equipment. 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. The current oxidation ditch has the problems of poor mud-water separation effect, short service life of the aeration device, easy blockage, high operating cost, and poor sludge treatment effect. To this end, we propose a new integrated oxidation ditch for sewage treatment. Contents of the invention [0003] The main purpose of the present invention is to provide a new type of integrated oxidation ditch for sewage treatment. The oxidation ditch includes anoxic, anaerobic, aerobic, ...
