Air-lift bottom-oxidation ditch system

Abstract

The utility model discloses an air push flow type bottom exposure oxidation ditch system belongs to biochemical treatment technical field of sewage treatment plant. The system includes oxidation ditch pool body, and oxidation ditch pool body is by the water inlet pipe, anaerobic area, anoxic area, aerobic area and water outlet pipe who links to each other in proper order is formed, and its characterized in that: the aeration assembly and push flow subassembly are equipped in the aerobic area, and the gas supply subassembly that supplies the aeration assembly and push flow subassembly is equipped with in the pool body side of aerobic area, and the aeration assembly and push flow subassembly are respectively by multiple aeration ware units and air push flow unit who set up along the pool body longitudinal interval are formed, and the air push flow unit includes gas supply cross pipe, and multiple gas supply vertical pipes who extend to the pool bottom and can be dismantled are arranged at the gas supply cross pipe interval, and the bottom push flow ware and middle push flow ware are all installed on the gas supply vertical pipe. The oxidation ditch system is the novel oxidation ditch system that sets high -efficient aeration, air push flow, convenient repair as a whole.
