Purification equipment and two-chamber type gas stripping equipment thereof

Abstract

The invention discloses purification equipment and two-chamber type gas stripping equipment thereof. The two-chamber type gas stripping equipment comprises an aeration device, a first partition wall and a second partition wall which are arranged in a biological pool, a lifting chamber is formed between the first partition wall and the second partition wall, and the aeration device extends into thelifting chamber; a third partition wall is arranged in the biological pool and located on the side, away from the first partition wall, of the second partition wall, and an air release chamber is formed between the third partition wall and the second partition wall; the bottom of the second partition wall is not in contact with the bottom surface of the biological pool, so that sludge flows intothe lifting chamber from the gas release chamber after the gas release chamber is communicated with the lifting chamber. The two-chamber type gas stripping equipment is additionally provided with thethird partition wall and the gas release chamber, the energy-saving effect is achieved, the technical problem of sludge concentration differential gradient control between functional areas communicated with the gas stripping equipment and required by daily engineering operation conditions can be solved, a gas diffusion device in the prior art is omitted, maintenance and repair are reduced, and thecost is effectively saved.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a two-chamber air lifting equipment. In addition, the present application also relates to a purification device comprising the above-mentioned two-chamber gas stripping device. Background technique [0002] At present, the backflow of sewage treatment mostly uses mechanical pump backflow, but due to its many wearing parts, heavy maintenance workload, high power consumption, small backflow ratio, biological treatment efficiency and removal effect are difficult to improve due to small backflow ratio, so it is urgently needed A new equipment that is more economical, requires less maintenance and repair work, and consumes less energy. [0003] In the existing technology, such as figure 1 As shown, the lifting equipment is mainly composed of the first partition wall, the second partition wall and the gas diffusion device, and the lifting chamber is formed by the first partit...

AI Technical Summary

Problems solved by technology

[0004] However, since the second partition wall is connected to the bottom of the second functional area, it is easy to cause the sludge concentration in the second functional area to be the same as that in the lifting chamber, and then it is lifted to the first level by the air diffusion device in the lifting chamber. The sludge concentration after the functional zone will not be much different from the sludge concentration in the original second functional zone, and it is difficult to achieve differentiated sludge concentration control
