Embodiment 1

[0037] Such as figure 1 Shown: a tower-type self-circulating aerobic degradation reactor, including a reactor body, the reactor body includes an upper aerobic degradation zone 11 and a lower anoxic reaction zone 10, and the anoxic reaction zone 10 is set There is a water inlet pipe 1, a water distribution system 15 and a mud discharge pipe 9, the water distribution system 15 is a spiral coil 16, and the spiral coil 16 has a certain spiral gap, and the center of the spiral coil 16 The end is a sealed structure, and the spiral coil 16 is provided with several water outlet holes 17 with openings downward, so that the waste water is evenly distributed on the bottom surface of the reactor body and forms a vertical upflow flow state. The aerobic Between the degradation zone 11 and the anoxic reaction zone 10, the microporous aeration system 14 connected with the air inlet pipe 2 is arranged, and the microporous aeration system 14 is arranged at 4.5 meters below the water surface of ...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that the water distribution system 15 includes a plurality of concentric water distribution rings 18, the water distribution rings 18 have several water outlet holes 17 with openings downward, and the adjacent water distribution rings The rings 18 are connected by a communication pipe 19, and the communication pipe 19 is tangent to the smaller water distribution ring of the two adjacent water distribution rings. The outermost water distribution ring 18 is connected to the water inlet pipe 1 . The central return pipe 8 passes through the innermost water distribution ring 18 .

[0044] The microporous aeration system includes a plurality of aeration layers, and each aeration layer is connected with a number of aeration heads through an aeration branch pipe, and the aeration layers are connected through communication pipes, and the communication pipes are connected to the inlet Tracheal connection. The gas-water ...

Embodiment 3

[0046] A method for performing aerobic degradation in a tower-type self-circulating aerobic degradation reactor of embodiment one or two, comprising the steps of:

[0047] 1) Inlet water: Wastewater containing organic matter is evenly distributed on the bottom surface of the reactor through the water inlet pipe and the water distribution system at the bottom of the reactor, and is evenly mixed with the sludge digestion liquid in the anoxic reaction zone to form a vertical upflow flow At the same time, the macromolecular organic matter in the wastewater is hydrolyzed and acidified into small molecules, the nitrate nitrogen in the digestive juice undergoes denitrification biological denitrification reaction, and the phosphorus accumulation bacteria release phosphorus. The sludge concentration in the anoxic reaction zone is 15000-20000mg / L;

[0048] 2) Aeration and oxygen supply: The sludge and wastewater mixture after the anoxic reaction rises to the aeration system. The resul...

Abstract

The invention discloses a tower-type self-circulation aerobic degradation reactor. Waste water is uniformly introduced into an anoxic reaction zone at the bottom of the reactor by virtue of a water inlet pipe and a water distribution system which are arranged at the bottom of the reactor, the waste water is jointly mixed and reacts with high-concentration sludge and digestive fluid which are arranged at the bottom of the reactor and mixed liquor refluxed through a central reflux pipe, the mixture rises for forming a vertically rising type flow state upward movement, and a water inlet pump and an aeration fan are used for providing power, so that no sludge, digestive fluid reflux pump and the like is needed; meanwhile, the aeration fan has low power requirement, a conventional air blower is needed only, and operating cost and management difficulty are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of aerobic biological treatment equipment, in particular to a tower-type self-circulating aerobic degradation reactor and an aerobic degradation method thereof. Background technique [0002] Aerobic biological treatment technology is a treatment method that uses aerobic microorganisms to perform biological metabolism in the presence of oxygen to degrade organic matter and make it stable and harmless. Microbes use organic pollutants in water as substrates for aerobic metabolism, release energy step by step through a series of biochemical reactions, and finally stabilize with low-energy inorganic substances to meet the requirements of harmlessness. [0003] The aerobic treatment technology that has been developed at present is widely used, but due to the limitation of the oxygen supply method, the traditional fan blowing aeration is used. Due to the limited wind force, the depth of the aeration tank of the rea...
