Embodiment 1

[0020] Such as figure 1 and figure 2 Shown is a preferred solution of the present invention, a hybrid biological contact oxidation tank, including a tank body 1, filler 4 and a hybrid aeration device, the inner bottom of the tank body 1 is provided with a base 12, and is fixed by the base 12 Hybrid aeration device.

[0021] Further, the hybrid aeration device includes a mixing chamber 8, an annular aeration pipe 9 and a water outlet 11, the outer wall of the mixing chamber 8 is fixed with an annular aeration pipe 9, and the inner ring of the annular aeration pipe 9 is There are eight sets of aeration inclined openings 10 at equal circle center angles on the surface. The aeration inclined openings 10 pass through the outer wall of the mixing chamber 8 and extend into the mixing chamber 8. Each set of aeration inclined openings 10 is provided with four aeration inclined openings 10 in the longitudinal direction. Slope 10, the outer side of the ring-shaped aeration pipe 9 is c...

Embodiment 2

[0023] This embodiment is further optimized on the basis of the above-mentioned embodiment, further to better realize the present invention; the lower part of one side of the outer wall of the pool body 1 is provided with an air compressor 5, and one end of the air inlet pipe 7 is connected to the air compressor 5 Connected, the aeration efficiency is increased by applying a certain wind pressure to the air intake, and the aeration inclined opening 10 is cleaned independently to avoid the situation that the sludge clogs the aeration inclined opening 10 .

Embodiment 3

[0025] This embodiment is further optimized on the basis of the above-mentioned embodiments, further to better realize the present invention; the filler 4 is a suspended filler, the specific surface area per unit of the suspended filler is large, the porosity is high, and the material is light and strong. , and can cut bubbles, increase the contact area of ​​the gas-liquid two-phase, and play a certain role in improving the oxygen capacity in water.

Abstract

The invention discloses a mixed biological contact oxidation tank which comprises a tank body, a suspension filler, a mixed aeration device and an air compressor, wherein the lower part of the tank body is provided with a pedestal; the pedestal is utilized to fix the mixed aeration device; the mixed aeration device comprises a mixing chamber and an annular aeration pipe; the annular aeration pipe is arranged on the mixing chamber; the inner ring of the annular aeration pipe is provided with a plurality of aeration chamfers; the outer side of the annular aeration pipe is connected with a gas inlet pipe; the other end of the gas inlet pipe is connected with the air compressor; and the lower part of the mixing chamber is connected with a water inlet pipe. The mixed biological contact oxidation tank is provided with the preparation stage, thereby enhancing the aeration efficiency, preventing the sludge from blocking the aeration port, and lowering the maintenance cost in the later period.

Description

technical field [0001] The invention belongs to sewage treatment equipment, in particular to a mixed biological contact oxidation pond. Background technique [0002] The biological contact oxidation method is a submerged biofilm method, which is actually a combination of a biological filter and an aeration tank. The biological contact oxidation method is also called submerged aerated biological filter. The pool is filled with various film-hanging media, and all filter materials are submerged in wastewater. An aeration tube is set at the lower part of the filter material, and the compressed air is used to bubble and oxygenate. The organic matter in the wastewater is adsorbed on the biofilm on the surface of the filter material, and is decomposed and oxidized by microorganisms. Like other biofilms, the biofilm of this method also undergoes replacement processes such as film formation, growth, thickening, and shedding. Part of the biofilm falls off and becomes activated slud...
