Problems solved by technology

[0003] At present, the commonly used aeration methods at home and abroad include blast aeration method, mechanical agitation method and jet aeration method, etc., but there are generally disadvantages such as low aeration capacity and oxygen utilization rate, uneven air distribution, etc.; often blocked or exposed , it is very difficult to repair and replace, and its power efficiency is lower
So far, the research and development and manufacturing processes of all aeration and oxygenation devices at home and abroad are primitive and simple, directly using mechanical methods to send ordinary air into the water, so that the oxygen in the air is naturally and inefficiently mixed into the water , so the mechanical power efficiency of the oxygen utilization rate is very low

Abstract

The invention discloses an oxygen gathering and nitrogen removing strong-oxidation two-way plug flow aerator with a high-gradient magnetic field, belonging to the technical fields of purification treatments of industrial wastewater and urban and rural domestic wastewater. The oxygen gathering and nitrogen removing strong-oxidation two-way plug flow aerator has a structure that a protective cover (1), a high-pressure fan (2) and an oxygen gathering and nitrogen removing device (3) are arranged above a square bearing platform slab (7); a spherical-end cylindrical floating body (9), two spherical floating bodies (11) and an oxygen activating device (12) are arranged below the square bearing platform slab (7); and a two-way plug flow aeration device is composed of an air inflow optimizing and shunting tee joint (14), a submersible motor (16) with double-end output shafts, an extremely-short hollow shaft (25), a spiral flow pusher (28) and water and stream stirring blades (27). All permanent magnets in all the devices are rare-earth permanent magnets (32) of which the middles are axially penetrated. Compared with the prior art, the oxygen gathering and nitrogen removing strong-oxidation two-way plug flow aerator has the advantages that the aeration and oxygenation effects are improved, and furthermore the wastewater purification effect is improved; in addition, the oxygen gathering and nitrogen removing strong-oxidation two-way plug flow aerator can be self-balanced and is more stable in operation, and the service life of the oxygen gathering and nitrogen removing strong-oxidation two-way plug flow aerator is prolonged.

Description

technical field [0001] The invention belongs to the technical field of purification treatment of industrial waste water and urban and rural domestic sewage, and relates to a bidirectional plug-flow aeration aeration device for oxygen-gathering and strong oxidation in a biological treatment process. Background technique [0002] There are a large number of microorganisms in sewage, which have the ability to digest and degrade complex organic matter and some types of inorganic matter in sewage, and convert these substances into simple, non-toxic and harmless substances. Practice has proved that the use of microorganisms to treat harmful pollutants in sewage has the advantages of low investment, high efficiency, simple operation, stable operation, low cost, good effluent quality, fast sludge settling speed, good performance, and can be used as fertilizer. Among the biological treatment methods, the activated sludge method has the advantages of basically no odor, short treatment...
