Abstract

The invention discloses an integrated A2-O oxidation ditch, which is characterized by comprising an ear-shaped anaerobic zone, an anoxic zone, an aerobic zone and a settling zone, wherein a sewage inlet pipe is arranged in the anaerobic zone; a plurality of submersible water impellers are arranged in each of the anaerobic zone, the anoxic zone and the aerobic zone; a plurality of aeration pipes arranged in the aerobic zone; and a sludge discharge pipe and a water outlet pipe are arranged in the settling zone. The invention aims to provide an A2O and settling integrated oxidation ditch with a simple structure and ideal treatment effect for overcoming the drawbacks of the prior art.

Description

technical field [0001] The present invention relates to an integrated A 2 -O oxidation ditch. Background technique [0002] A 2 The O method, also known as the AAO method, is the abbreviation of the first letter of the English Anaerobic-Anoxic-Oxic anaerobic-anoxic-aerobic method, and is a commonly used sewage treatment process. Existing for integration A 2 The oxidation ditch structure of O sewage treatment is relatively complex, and its treatment effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure in order to overcome the deficiencies in the prior art, A 2 Oxidation ditch with good integrated treatment effect of O and precipitation. [0004] In order to achieve the above object, the present invention adopts the following scheme: [0005] an all-in-one A 2 O oxidation ditch, it is characterized in that comprising the anaerobic zone, the anoxic zone, the aerobic zone and the sedimentation zone...
