Description

Technical Field

[0001] The utility model belongs to the technical field of aeration tanks, and particularly relates to an aeration tank with uniform upper and lower aeration. Background Art

[0002] An aeration basin is a biochemical reaction facility specially used for sewage treatment. It uses the activated sludge method to treat sewage. The aeration basin fills the sewage with air through its internal aeration system to ensure that aerobic microorganisms obtain sufficient dissolved oxygen, so that they can effectively survive, proliferate and degrade organic pollutants in the sewage. An aeration basin usually consists of three parts: the tank body, the aeration system and the inlet and outlet. The tank body is usually made of reinforced concrete and can be designed in a variety of shapes such as rectangular, square or circular to meet different engineering needs and process flows.

[0003] In the aeration tank, sewage and activated sludge are mixed evenly and stay for a certain period of time, so that microorganisms can fully contact with organic matter in sewage and oxidize and decompose it, thereby achieving the purpose of purifying water quality. The aeration tank is the core component of the activated sludge sewage treatment process.

[0004] Most of the existing aeration tanks are equipped with aeration structures at the bottom for aeration, or rely on agitation equipment floating on the water surface to aerate the water in the aeration tank. This aeration method is prone to uneven aeration, and uneven aeration in the upper and lower parts of the tank will lead to uneven distribution of microbial populations. Aerobic, facultative anaerobic and anaerobic microorganisms have different growth rates and activities under different oxygen concentrations, thus affecting the stability and efficiency of biological reactions such as organic matter degradation, nitrification, and denitrification. This may cause fluctuations in effluent water quality and make it difficult to achieve stable discharge standards. Therefore, we hope to design an aeration tank with a new structure to solve this problem. Utility Model Content

[0027] See also Figures 1 to 5 The utility model provides a technical solution: an aeration tank with uniform aeration from top to bottom, comprising: an aeration tank body 100, an aeration component 1 200 and an aeration component 2 300, wherein a plurality of aeration components 1 200 for three-dimensional aeration are arranged inside the aeration tank body 100, and an aeration component 2 300 is installed on the upper side of the aeration tank body 100 through a plurality of aeration components 1 200;

[0028] The aeration assembly 200 includes a column 210 and a main air pipe 220. The main air pipe 220 is embedded and fixed inside the column 210, and the upper end of the main air pipe 220 is connected to the delivery pipe 240.

[0029] The aeration assembly 2 300 includes a mounting frame 310 and a stirring member 320 . The mounting frame 310 is fixed between a plurality of columns 210 , and the stirring member 320 is installed in the middle of the mounting frame 310 .

[0030] Please refer to the figure, the column 210 is a reinforced concrete cylindrical structure, the height of the column 210 is greater than the depth of the aeration tank body 100, and each column 210 is pre-buried with a row of vertical connecting air pipes 221 on the front, rear, left and right sides, and the inner ends of the multiple rows of connecting air pipes 221 are connected to the main air pipe 220. In actual use, the number and position of the aeration components 200 can be set according to actual use requirements. When arranging the aeration components 200, it is necessary to place the multiple aeration components 200 in the aeration tank close to the edge of the aeration tank, and the distance should be 0.5 meters to 1 meter. This helps the aeration components 200 to cooperate with the inner wall of the aeration tank to mix the sewage, so that the aeration is more uniform and thorough. Different numbers of aeration components 2 300 can be installed between the multiple aeration components 200 according to actual use requirements. One aeration component 2 300 can be installed between every four aeration components 200, which helps to assist the upper sewage in rapid and uniform aeration.

[0031] A plurality of equally spaced three-dimensional aeration components 230 are fixed to the outside of the column 210 through a connecting air pipe 221 . The three-dimensional aeration component 230 includes a ring pipe and an aeration head 231 . The left inner wall, right inner wall, front inner wall and rear inner wall of the ring pipe are all fixedly connected to the outer end of a connecting air pipe 221 .

[0032] A plurality of aeration heads 231 distributed in a ring structure are arranged on the upper outer side of the annular tube, and a plurality of aeration heads 231 distributed in a ring structure are arranged on the lower outer side of the annular tube. The aeration heads 231 on the upper outer side of the annular tube are arranged upwardly inclined at forty-five degrees, and the aeration heads 231 on the lower outer side of the annular tube are arranged downwardly inclined at forty-five degrees. The sewage near the column 210 can be aerated and pushed in different directions, so that the sewage is in a state of pneumatic stirring, thereby enhancing the aeration effect.

[0033] An air branch pipe is provided at the lower end of the main air pipe 220 , and the air branch pipe is vertically connected to the main air pipe 220 , and the air branch pipe passes through the lower end of the column 210 in the front-to-back direction.

[0034] The air distribution pipe is connected to the bottom aeration member 250 , and the bottom aeration member 250 is evenly distributed in the bottom space of all aeration tank bodies 100 except the columns 210 . A plurality of aeration heads 251 are evenly installed on the upper side of the bottom aeration member 250 .

[0035] As the first embodiment of the utility model, in actual use, when the interior of the aeration tank body 100 is filled with sewage that needs to be aerated, high-pressure gas is delivered to the upper ends of the main gas pipes 220 on the multiple aeration components 200 through the delivery pipe 240 (multiple main gas pipes 220 can be connected to the same delivery pipe 240, and the specific connection structure and method can be set according to the arrangement position and distance of the columns 210, and are not limited to a certain arrangement structure). After the main gas pipes 220 in the multiple columns 210 are charged with high-pressure gas, they are quickly distributed to the multiple connecting gas pipes 221 in a uniform portion. The sewage is transported into the annular tube of the three-dimensional aeration element 230, and is further transported to a plurality of inclined aeration heads 231, and is finally discharged through the aeration holes on the aeration head 231, so as to aerate and push the sewage near the aeration head 231, and can aerate the sewage near the aeration head 231 and push it in a direction away from the aeration head 231.

The aeration component is installed here, and the drive motor is started synchronously to drive the multiple propellers 322 on the lower side of the shaft 321 to mechanically stir the sewage at this position (the length of the stirring piece 320 can be set according to actual use requirements, and cannot be too close to the bottom aeration piece 250, and a distance of at least 20 cm is retained). In conjunction with the four aeration components 200 and the bottom aeration piece 250 (the bottom aeration piece 250 needs to evenly cover the bottom of the aeration tank body 100 except the space occupied by the columns 210), the sewage here can be aerated to the maximum extent, so that the sewage inside the entire aeration tank body 100 can be evenly aerated.
