Problems solved by technology

[0003] In the process of sewage treatment, the sewage treatment of activated sludge method is realized by aeration, which meets the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. The degree of refinement of the air introduced in the medium is not enough, and the oxygen in the air cannot fully contact with the activated sludge, resulting in low efficiency of sewage treatment. Therefore, a high-efficiency aeration device for water pollution control is now provided to use Solve the above technical problems

Embodiment 1

[0021] see Figure 1-3 , a high-efficiency aeration device for water pollution control, comprising a base plate 1, a support frame 2 is fixedly installed on the base plate 1, an aeration box 9 is fixedly installed on the base plate 1, and the aeration box 9 is used to store the sewage to be treated, Activated sludge for treating sewage is added inside the aeration box 9 .

[0022] Inside the aeration box 9, a rotating sleeve 16 is rotatably and vertically worn, the lower end of the rotating sleeve 16 is connected with a rotating disk 8, and the bottom surface of the rotating disk 8 is evenly and fixedly installed with a number of longitudinal aeration nozzles 21 communicated with the inside thereof. Between the aeration nozzles 21, a stirring plate 19 fixed on the bottom of the rotating disk 8 is vertically arranged, an air pump 11 is fixedly installed on the bottom plate 1, and the outlet end of the air pump 11 is connected and installed with an air intake pipe 17 extending t...

Embodiment 2

[0026] On the basis of Embodiment 1, in addition, a rotating sleeve II13 is rotatably and horizontally penetrated in the aeration box 9, and the rotating sleeve II13 penetrates and installs an intake pipe II12 communicating with the intake pipe I7, and the rotating sleeve II13 A number of aeration pipes 14 communicated with the inside of the aeration pipes 14 are fixedly installed on the sidewalls at equal intervals in the lateral direction.

[0027] Part of the compressed air pumped by the air pump 11 enters the rotating sleeve II13 through the air intake pipe II12, the air enters the aeration pipe 14 and is finally sprayed laterally into the aeration tank 9 through the lateral aeration nozzle 16, so as to realize the discharge from the aeration tank. 9 The lower half of the oxygen supply.

[0028] Further, a drive motor 23 is fixedly installed on the base plate 1, and the output shaft of the drive motor 23 is connected to the rotating sleeve II13 through a pulley mechanism I...

Abstract

The invention discloses an efficient aeration device for water pollution control and relates to the technical field of sewage treatment. The efficient aeration device comprises a bottom plate, a supporting frame is fixedly mounted on the bottom plate, an aeration box is fixedly mounted on the bottom plate, a rotating sleeve I is rotatably, vertically and penetratingly arranged in the aeration box,a plurality of longitudinal aeration nozzles communicated with the inside of a rotating disc are uniformly and fixedly mounted on the undersurface of the rotating disc, and stirring plates fixed at the bottom of the rotating disc are vertically arranged among the longitudinal aeration nozzles. The efficient aeration device is ingenious in structure; air is pumped into the aeration box by an air pump through delivering by an air outgoing pipe and then sprayed out by the longitudinal aeration nozzles and transverse aeration nozzles to realize dispersing refinement of the air; the rotating discrotates to drive the stirring plate to rotate to realize scattering refinement; a rotating sleeve II drives aeration pipes to rotate, so that rotating dispersion of the air is promoted, oxygen contentinside the aeration box is increased greatly, oxygen is utilized more sufficiently by activated sludge, own activity is improved greatly, and sewage treatment efficiency is improved remarkably.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency aeration device for water pollution treatment. Background technique [0002] Sewage treatment (sewage treatment, wastewater treatment): The process of purifying sewage in order to make it meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc. It is also increasingly entering the daily life of ordinary people. Surface water pollution is obvious, groundwater pollution But it was startling. 70% of China's 1.3 billion people drink groundwater, and more than 400 of the more than 660 cities use groundwater as a source of drinking water. However, according to reports, 90% of the city's groundwater has been polluted. [0003] In the process of...
