Problems solved by technology

[0005] Another type of traditional aeration and oxygenation method is surface aeration (or called sub-rotating disc, rotating brush aeration), which uses a high-speed rotating mechanical device to blow oxygen in the air into the water. The method is relatively energy-saving, but subj

Example Embodiment

[0067] Example 1

[0068] like figure 1 As shown, this embodiment provides a sewage oxygenation system, including: an aerobic tank 1, a sewage circulation device 2, a water distribution system 3, an oxygenated filler 4, a return device 5 and a partition 6;

[0069] The partition 6 divides the aerobic tank 1 into a circulation area and an oxygenation area. The sewage circulation device 2 is located in the circulation area, and the return device 5 extends into the oxygenation area. Oxygen filling 4;

[0070] In the present invention, the water distribution system 3 includes a water distribution pipeline and a valve 31, and the valve 31 is mainly used to control the water distribution flow. The water distribution system 3 also includes a spray device, which can be a spray head arranged at the end of the water distribution pipe or a through hole evenly arranged on the outer wall of the water distribution pipe, which can ensure that the sewage is evenly sprayed on the surface of ...

Example Embodiment

[0083] Example 2: Comparative Example

[0084] like figure 2 As shown, the present embodiment provides a traditional blast aeration and oxygenation system, including: aerobic tank 1', aeration head 2'; aeration piping system 3'; blower 4'.

[0085] The traditional blast aeration oxygenation system uses the blower 4' to pump the air into the aeration pipe system 3' at the bottom of the aerobic tank 1', and then aerates the air to the aerobic tank 1 through the aeration head 2' 'The sewage inside, realize the oxygenation of sewage.

[0086] In this embodiment, the required blower 4' has a relatively large lift, which is generally the water depth plus the resistance of the aeration pipeline system, while the pool depth of the traditional aerobic pool 1' is generally 4-5 meters. Therefore, the required air pressure of the blower 4' is For 5-7 meters head. After the air bubbles (air) enter the bottom of the tank, they rise rapidly, the residence and mass transfer time in the ta...

Abstract

The invention relates to a sewage oxygen charging system and an oxygen charging method. The sewage oxygen charging system comprises an aerobic tank, a sewage circulation device, a water distribution system, an oxygen charging filler, a reflux device and a clapboard, wherein the aerobic tank is divided into a circulation area and an oxygen charging area through the clapboard; the sewage circulation device is located in the circulation area; the reflux device stretches into the oxygen charging area; the water distribution system is connected with the sewage circulation device and lifts sewage to the oxygen charging filler; the oxygen charging filler is located above the aerobic tank; the reflux device is located under the oxygen charging filler. The invention also provides the oxygen charging method of the sewage oxygen charging system. According to the oxygen charging system and the oxygen charging method provided by the invention, heat can be exchanged and temperature can be adjusted during an oxygen increasing process, and the advantages of lower aeration consumption, good oxygen charging effect, easiness in overhaul and maintenance, and the like are achieved.

Description

technical field [0001] The invention relates to a sewage oxygenation system and an oxygenation method, in particular to a sewage oxygenation system capable of heat exchange and temperature adjustment during the oxygenation process, with low energy consumption, good oxygenation effect, and easy repair and maintenance The invention relates to an oxygenation method, which belongs to the technical field of water treatment oxygenation. Background technique [0002] At present, there are two main types of aeration and oxygenation methods in aerobic ponds: [0003] One is the method of blowing aeration and oxygenation. The oxygenation system adopting this oxygenation method uses a blower to blow air into the water. During the process of air bubbles rising, gas-liquid two-phase mass transfer occurs, so that the water dissolves Oxygen is replenished. The blowing aeration and oxygenation method is suitable for large, medium and small sewage treatment scales. [0004] However, this ...
