Embodiment 2

[0054] Comply with the above technical solutions, such as Figure 1 to Figure 2 As shown, this embodiment provides a device for improving water quality by air bubble cutting biological contact oxidation enhanced pumping and aeration, which includes a rising cylinder unit 1, a main aeration unit 2 is arranged at the bottom of the rising cylinder unit 1, and a bottom end of the rising cylinder unit 1 is provided with An anchoring unit 3, a biological contact oxidation unit 4 is arranged on the top of the ascending cylinder unit 1;

[0055] The biological contact oxidation unit 4 adopts the biological contact oxidation device described in Example 1.

[0056] During the operation of the equipment, the rising water flow enters the filler filling chamber 405 through the air bubble cutting water distribution grid 404, and the water body is in contact with the filler, thereby performing bioremediation of the water body through biological contact oxidation, effectively reducing the con...

Embodiment 3

[0059] Comply with the above technical solutions, such as Figure 2 to Figure 3 As shown, this embodiment provides a device for improving water quality by air bubble cutting biological contact oxidation enhanced water pumping and aeration. And the anchoring unit 3 can take the following specific scheme as an example to illustrate the scheme of the present application.

[0060] Specifically, the ascending cylinder unit 1 includes an upper ascending cylinder 101 and a lower ascending cylinder 102 connected together by a flange 103, the top of the upper ascending cylinder 101 is affixed to the bottom of the cabin body 101; The end is affixed to the trumpet-shaped inlet 301 of the anchor unit 3 .

[0061] Both the upper ascending cylinder 101 and the lower ascending cylinder 102 are provided with an airtight chamber 104; the airtight chamber 104 is used to provide buoyancy, and the fixed cylinder is relatively stable and suspended in water.

[0062] Lifting lugs 105 are provided...

Abstract

A water-lifting aeration water quality improving device enhanced through bubble cutting and bio-contact oxidation is provided. A lifting center cylinder is disposed in a cabin body of a bio-contact oxidation unit. The cabin body, the lifting center cylinder and a rising cylinder unit are coaxially arranged. A chamber between the cabin body and the lifting center cylinder is a filler filling chamber. The filler filling chamber is provided with a plurality of double-layer punched plates along the axial direction. The double-layer punched plates partition the filler filling chamber. A resistancereducing slot is disposed between two layers of each double-layer punched plate. A plurality of meshed ball shells are disposed in the filler filling chamber and contain a filler. The device combinesa bubble cutting aeration process and a bio-contact oxidation process, oxygen-rich water aerated by a water lifting aerator is brought into contact with a bio-contact oxidation gear in a process thatwater is lifted by the water lifting aerator, and concentrations of COD, N, P and other pollutants in water of a water source can be more effectively reduced, thus overcoming a water source pollutionproblem from the source.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a pumping and aerating device, in particular to a device for improving water quality by air bubble cutting biological contact oxidation enhanced pumping and aerating. Background technique [0002] Generally, reservoirs and lakes have large water capacity and low fluidity, and many nutrients such as organic carbon, nitrogen, and phosphorus are deposited and accumulated at the bottom, providing sufficient nutrients for aquatic algae and other plankton all year round, and algae can stay in the water stably and receive light to grow in large numbers. Breeding, causing eutrophication of water bodies and affecting water quality. For deep-water source reservoirs and lakes, due to the more stable stratification of the water body, the lower water body is in anaerobic or anoxic state for a long time, the ecological environment deteriorates, and a large number of pollutants in the bottom sedime...
