Aeration tank with safe microporous aerator

Abstract

The invention discloses an aeration tank with a safe microporous aerator. The aeration tank comprises an aeration tank body, a head aeration pipe, a head pipe, a vertical liquid guide pipe and a valve; the head aeration pipe is arranged at the bottom part of the aeration tank body and connected with at least two aeration pipes, wherein the at least two aeration pipes are uniformly distributed at the bottom part of the aeration tank body; magnets are arranged on the aeration pipes; absorption parts matched with the magnets are arranged at the bottom part of the aeration tank body; supporting pipes of which two ends are opened are arranged at intervals on the aeration pipes; concave grooves are formed in the supporting pipes along the length direction and form an air channel with an air distributing pipe membrane on the outer surface of each supporting pipe; a plurality of micropores are closely distributed in the air distributing pipe membranes. According to the aeration tank with the safe microporous aerator, the uniformity of aerating is realized, the vibrating in aerating is removed, the service life is prolonged, the overhaul and maintenance are reduced, high oxygen transfer rate is ensured, the requirement of mixing agitating is met, the oxygen transfer rate is high, the energy consumption is small, the performance on resisting blocking is high, blocking is greatly avoided, the aerating effect is great, the aerating capacity is high, the applicable scope is wide.

Description

technical field [0001] The invention relates to an aerator, in particular to an aeration tank with a safety microporous aerator. Background technique [0002] At present, the microporous aerator generally adopts the disc-type suspension aerator head, and the following problems exist in the use of the disc-type suspension aerator head: the diameter of the bubbles diffused by the aerator is large, and the oxygen utilization rate is low. The sewage cannot be fully mixed, and the activated sludge cannot be guaranteed to be in a suspended state, resulting in dead sludge at the bottom of the pool; the disc suspension aerator has high energy consumption and low efficiency; the disc aerator has poor anti-blocking performance, once When the sewage plant is out of operation, the sludge can be blocked by sludge particles when it settles down. Contents of the invention [0003] The purpose of the present invention is to provide an aeration tank with a safe microporous aerator with lo...
