Oxygen-rich suspending chain type microporous aerating device

Abstract

The invention discloses an oxygen-rich suspending chain type microporous aerating device. The device comprises an air compressor, a main oxygen preparing machine, a gas inlet pipe, a high tower aerating pond, a three-phase separator and a water absorbing pump; the air compressor is connected with the main oxygen preparing machine; the oxygen preparing machine is used to prepare oxygen by the PSA (Pressure Swing Adsorption) method; one end of the gas inlet pipe is connected with the main oxygen preparing machine and while the other end of the gas inlet pipe extends through the aerating pond; pure oxygen prepared by the main oxygen preparing machine enters the gas inlet pipe; a stop valve and a filter are arranged on the gas inlet pipe; a condensate water draining valve is arranged at the tail end of the gas inlet pipe; at least two gas inlet hoses which are connected with an aerating pipe are connected to the gas inlet pipe; two ends of the aerating pipes are sealed; the aerating pipe is also equipped with falling parts which are symmetrically arranged at two sides of the aerating pipe; the falling parts are suspended on the gas inlet pipe through a suspending chain. According to the oxygen-rich suspending chain type microporous aerating device, blocking is greatly avoided, the aerating effect is great, the oxygenation capacity is high, the generation of some anaerobic bacteria (facultative anaerobic bacteria) can be effectively inhibited, and the strength of ozone is also reduced.

Description

technical field [0001] The invention relates to an aeration device, in particular to an oxygen-enriched suspended chain microporous aeration device. Background technique [0002] At present, the microporous aerator generally uses a disc-type suspension aerator head, and the use of a disc-type suspension aerator head has the following problems: 1. The diameter of the bubbles diffused by the aerator is large, and the oxygen utilization rate is relatively low. low, so that 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; 2. The disc suspension aerator has high energy consumption and low efficiency; 3. The disc aerator is resistant to The plugging performance is poor. Once the sewage plant is out of operation, the sludge will be blocked by sludge particles after it settles down. Contents of the invention [0003] The object of the present invention is to provide an o...
