Novel quick-installation aeration connector for membrane bioreactor

Abstract

The invention relates to a novel quick-installation aeration connector for a membrane bioreactor. The novel quick-installation aeration connector for the membrane bioreactor is characterized by comprising an injector (1), wherein the upper part of the injector (1) is a mixing chamber (2), while the lower part is a suction chamber (3); the mixing chamber (2) is communicated with the suction chamber (3); an air inlet (10) is formed on a side wall of the suction chamber (3); a nozzle head (4) is arranged in the suction chamber (3); the lower end of the nozzle head (4) is positioned on the outer part of the lower end of the injector (1) and provided with a circle of bulges (5);a spiral connector (6) of which the lower end is provided with internal screw threads is arranged at a position of the bulges (5); a water inlet pipe (7) is arranged below the injector (1) and provided with a spiral adaptor pipe (8); and the outside wall of the spiral adaptor pipe (8) is provided with an external screw thread structure which is matched with the internal screw threads in the spiral connector (6). The novel quick-installation aeration connector for the membrane bioreactor has small investment and a simple and practical structure, the aerating connector is convenient to assembly and maintain, and the treatment efficiency is high.

Description

technical field [0001] The invention relates to the technical field of domestic sewage and industrial wastewater treatment equipment, which is a biological reaction wastewater treatment equipment combined with activated sludge method and biofilm, and is also a new type of membrane bioreactor quick-installed aeration joint. Background technique [0002] At present, the aeration joints for membrane bioreactors on the market are generally connected by clamps. This connection method not only affects the sealing performance, but also the accessories can only be used once, which is a great waste, especially because of poor sealing performance, which affects the aeration effect. Although there is also a method of directly welding together by electric welding in the existing market, although this solves the sealing problem, it can only be used for one time, which increases the maintenance cost. Normal use of membrane bioreactors. Contents of the invention [0003] The purpose of ...
