Problems solved by technology

Therefore, in the existing sewage treatment technologies, they are all limited to single use of water jumping aerators or underwater blowing aerators, and because the uniformity of dissolved oxygen distribution in the water body is ignored, the stirring mechanism is basically not used, resulting in the aeration of sewage. Low efficiency and high energy consumption in the gas treatment process

Embodiment Construction

[0025] Now how the present invention is implemented in conjunction with the accompanying drawings:

[0026]The integrated aeration device is composed of air compressor 1, compressed air main pipe G and compressed air branch pipes G1 and G2, two rows of aeration rotor row P1, two rows of stirring rotor row P2, two groups of micro The hole aeration ring tube group P3 is composed. The row of aeration rotors P1 and the row of agitating rotors P2 are arranged in a straight line and are perpendicular to the compressed air main pipe G and are symmetrically cross-connected. P1 is located at the upper part of compressed air main pipe G. The stirring wheel row P2 and the microporous aeration ring pipe group P3 are located at the lower part of the compressed air transmission main pipe G, and are arranged alternately at equal intervals from top to bottom in the order of P2, P3, P2, and P3. The main compressed air pipeline G is arranged vertically, and the compressed air branch pipes G1 ...

Abstract

The invention relates to a high-efficiency integral aerating device for sewage treatment, belonging to the field of sewage treatment aerating equipment. The device is composed of an air compressor, a compressed air delivery pipe system, a water-surface water-jump aeration mechanism, an underwater blast aeration mechanism and an underwater stirring mechanism, wherein the water-surface water-jump aeration mechanism is aeration rotary-axe wheel rows which are communicated by connecting compressed air delivery branch pipes in series, and the aeration rotary-axe wheel rows are communicated with the upper parts of air delivery main pipes through the air delivery branch pipes and are arranged on the surface of a water body; the underwater blast aeration mechanism is microporous aeration circular pipes, and the microporous aeration circular pipes are communicated with the compressed air delivery main pipes through microporous radial-connecting pipes and are arranged in the water body; the stirring mechanism is stirring wheel rows which are communicated by connecting the compressed air delivery branch pipes in series, and the stirring wheel rows are communicated with the air delivery main pipes through the air delivery branch pipes and are arranged between the aeration rotary-axe wheel rows and the microporous aeration circular pipe groups and between upper and lower microporous aeration circular pipe groups respectively. A set of compressed air power source is adopted, dissolved oxygen in the water body is integrally, efficiently, synchronously increased and is quickly and uniformly distributed, and the aeration efficiency and the energy utilization rate are significantly increased.

Description

technical field [0001] The invention relates to a high-efficiency integrated aeration device for sewage treatment, which belongs to the field of sewage treatment aeration equipment. Background technique [0002] Excessive energy consumption is the main problem in the operation of urban sewage treatment plants. How to save energy and reduce consumption in urban sewage treatment plants to reduce sewage treatment costs has always been the focus of research. Studies have shown that the energy consumption of urban sewage plants is mainly concentrated in the aerobic aeration process necessary for the sewage treatment process, and the energy consumption of this process generally accounts for more than 80% of the total energy consumption of the sewage plant. The efficiency is the key to realize the high efficiency and low consumption operation of the sewage plant. [0003] There are two types of aerators currently used for sewage treatment: surface jump aerators and underwater blas...
