Purification oxygen flotation aeration device

Abstract

The invention belongs to the technical field of waste water sewage treatment, and discloses a purification, oxygenation, air floatation and aeration device. The purification, oxygenation, air floatation and aeration device consists of a semispherical protective cover (1), a conical floating body (9), a high-end high-pressure fan (3) and a submersible motor (11), wherein an oxygen-gathering rare earth permanent magnet (4) and an LC oscillator (26) are arranged in a vertical drum (2), and air inlets (5) are formed; a boosting stirring blade (16) and a fly-cutter-shaped flow push blade (15) are arranged at the tail end of an ultra-short hollow shaft (14); a sealed cabin (12) filled with nano graphite powder and an air supply cabin (13) are arranged coaxially with the ultra-short hollow shaft (14); the high-end high-pressure fan (3) is used for conveying oxygen-gathering high-pressure air into the underwater air supply cabin (13) through a non-eddying-flow storage air supply cabin (7) and a resistance-free air guide pipe (8). By adopting the purification, oxygenation, air floatation and aeration device, the oxygen-gathering capability, oxygen dissolving capability and rich oxygen transfer rate are increased, the water purification efficiency is increased, a water purification effect is enhanced, the influence of wind waves can be reduced, parasitism of scallops and snails is prevented, and heat-dissipating, lubricating, dust prevention and rainwater prevention effects are achieved. The device can run safely and stably.

Description

technical field [0001] The invention belongs to the technical field of waste water and sewage treatment, and in particular relates to a high-efficiency oxygen-increasing flotation aeration device used for biological treatment of industrial waste water and urban domestic sewage purification. Background technique [0002] There are a large number of microorganisms in nature, which have the ability to digest and degrade complex organic matter and some types of inorganic matter in water, and convert these substances into simple, non-toxic and harmless substances. Practice has proved that the use of microorganisms to treat harmful pollutants in wastewater has the advantages of low investment, high efficiency, stable operation, low operating costs, good effluent quality, good sludge settlement performance, and can be used as fertilizers. Among the biological treatment methods, the activated sludge method has the characteristics of basically no odor, short treatment time and high t...

Problems solved by technology

Since 1919, ceramic microporous aerators have been used in activated sludge, and different materials and types of microporous aerators developed and used later have affected their use due to technical problems such as micropore blockage.

Since the 1970s, various types of blower aeration equipment have been introduced in my country, and spiral aerators and jet aerators for deep water aeration have been developed successively. Low, uneven air distribution, etc., often blocked or exposed, very difficult to repair and replace, and its power efficiency is lower

In short, so far, all the research and development and manufacturing processes of aeration and oxygenation devices at home and abroad are primitive, all of which are simple, and directly use mechanical methods to send ordinary air into the water, so as to promote the oxygen in the air to rely on its natural inefficiency. mixed into water, so the utilization rate of oxygen and the power efficiency of machinery are very low
