Embodiment

[0018] Embodiment: a kind of oxygen-enriched biological oxidation system, comprises biological oxidation tank 1, aeration device and clear water tank 2, is filled with activated sludge in biological oxidation tank 1, and activated sludge purifies the sewage in biological oxidation tank, the sewage after treatment The filtered sediment enters the clear water pool 2.

[0019] The aeration device includes an aerosolizer 4 and a releaser 6. The aerosolizer 4 has a gas inlet, a water inlet and a water outlet. The gas inlet is connected to the air compressor 5, and air is passed into the aerosolizer 4. The water inlet passes through a pipeline. It is connected with the water pump 3 and the clean water tank 2, and part of the water in the clean water tank 2 is passed into the air dissolver 4, and the air in the air dissolver 4 is dissolved into the water under pressure to form dissolved air water.

[0020] The water outlet is connected with the releaser 6, which is an aerosol release...

Abstract

The invention discloses an oxygen-enriching biological oxidation system, which comprises a biological oxidation pool and an aeration device, wherein activated sludge is filled in the biological oxidation pool; the aeration device comprises an air dissolving device and a releaser; the air dissolving device is provided with an air inlet, a water inlet and a water outlet; air and water are respectively introduced into an inner cavity of the air dissolving device from the air inlet and the water inlet; air in the air dissolving device is dissolved into water under the pressure state to form air dissolving water; the water outlet is connected with the releaser; the releaser is arranged in the biological oxidation pool and is covered by the activated sludge; the air dissolving water in the air dissolving device is released into the biological oxidation pool by the releaser. The oxygen-enriching biological oxidation system has the advantages that clean water and air are simultaneously pumped into the air dissolving device by using an air dissolving mechanism; the air is blended into the water under the pressure state; the air dissolving water is formed and is then released into the biological oxidation pool; through oxygen-enriching water, the utilization capability of microbes on the air is greatly improved; the effective utilization rate of the air is improved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a biological oxidation system for aerobic biological treatment. Background technique [0002] The activated sludge method is an aerobic biological treatment method for sewage, which was invented and applied by Clark and Gage in Manchester at the Lawrence Sewage Test Station in Manchester around 1913. Today, the activated sludge process and its derivative improvement processes are the most widely used methods for treating municipal sewage. It can remove dissolved and colloidal biodegradable organic matter, suspended solids and other substances that can be adsorbed by activated sludge from sewage, and can also remove part of phosphorus and nitrogen, which are suspended in water for wastewater biological treatment. A collective term for various methods of micro-organisms. [0003] A typical activated sludge process is composed of an aeration tank, a sedimentation tank, a sludge ret...
