Abstract

The utility model discloses a contact oxidation pond device, which comprises a water inlet pipe, an air inlet pipe, a filler, a water outlet pipe and a pond body; waste water enters the cell body through the water inlet pipe, the air inlet pipe oxygenizes the waste water and enables the sewage in the cell body to be in a flowing state so as to ensure that the sewage is fully contacted with the filler in the sewage and avoid the defect that the contact between the sewage and the filler is uneven in the biological contact oxidation cell. The oxygen required by the microorganisms in the filler is supplied by the air inlet pipe, after the biofilm grows to a certain thickness, the microorganisms on the wall of the filler can carry out anaerobic metabolism due to oxygen deficiency, the produced gas and the scouring action formed by aeration can cause the shedding of the biofilm and promote the growth of a new biofilm, and at the moment, the shed biofilm flows out of the pool through the water outlet pipe. The utility model discloses a data calculation comparatively reasonable, can effectually get rid of aquatic COD, and only need 0.5h-1.0h just can reach the 8h effect of activated sludge method. The sludge load is small, and the wastewater is fully contacted with the filamentous fungi in the filler.

Description

Contact oxidation pond device

Technical Field

The utility model relates to the technical field of an activated sludge process, in particular to a contact oxidation pond device.

Background

The biological contact oxidation method is a high-efficiency water treatment process for purifying organic wastewater by mainly using a biological film attached to a carrier (commonly called as a filler). Is a biomembrane method with the characteristics of an activated sludge method, and has the advantages of both the activated sludge method and the biomembrane method. Under the biochemical condition, the method obtains good economic benefit no matter being applied to the treatment of industrial wastewater, breeding sewage and domestic sewage. The process has the characteristics of high efficiency, energy conservation, small occupied area, impact load resistance, convenient operation and management and the like, and is widely applied to sewage treatment systems in various industries.

The biological treatment is a link after physicochemical treatment and is also an important link in the whole sewage treatment circulation flow, and harmful substances such as ammonia nitrogen, nitrous acid, nitrate, hydrogen sulfide and the like are removed, so that the biological treatment plays a key role in further treatment of water quality in the subsequent flow.

However, the contact oxidation pond designed on the market often has the conditions of sludge death, sludge disintegration and water load.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a contact oxidation pond device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a contact oxidation tank device comprises a water inlet pipe, an air inlet pipe, a filler, a water outlet pipe and a tank body; waste water enters into the cell body through the inlet tube, and the intake pipe oxygenates waste water and makes sewage be in the mobile state in the cell body, and the equipartition of packing is in the cell body, set up the oxidation pond between the packing, the required oxygen of microorganism is supplied with by the intake pipe in the packing, and sewage flows out outside the pond by the outlet pipe after the oxidation in the cell body.

Preferably, the effective contact time of the sewage in the tank body is generally 1.5-3.0 h.

Preferably, the filler is honeycomb type filler, and is filled in layers, the height of each layer is 1m, and the pore diameter of the honeycomb is not less than 25 mm.

Preferably, the area of every other oxidation pond containing the filler in the pond body is generally not more than 25m²。

Compared with the prior art, the beneficial effects of the utility model are that: the data calculation is reasonable, COD in water can be effectively removed, and the effect of 8h of the activated sludge method can be achieved only by 0.5h-1.0 h. The sludge load is small, and the wastewater is fully contacted with the filamentous fungi in the filler.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a contact oxidation tank device comprises a water inlet pipe 1, an air inlet pipe 2, a filler 3, a water outlet pipe 4 and a tank body 5; waste water enters the cell body 5 through the water inlet pipe, and the air inlet pipe 2 oxygenizes the waste water and makes the sewage in the cell body 5 be in a flowing state to guarantee that the sewage fully contacts with the filler 3 in the sewage, and avoid the defect of uneven contact between the sewage and the filler existing in the biological contact oxidation tank. Oxygen required by microorganisms in the filler 3 is supplied by the air inlet pipe 2, after the biofilm grows to a certain thickness, the microorganisms on the wall of the filler can carry out anaerobic metabolism due to oxygen deficiency, the produced gas and the scouring action formed by aeration can cause the falling of the biofilm and promote the growth of new biofilm, and at the moment, the fallen biofilm flows out of the pool through the water outlet pipe 4.

Preferably, the effective contact time of the sewage in the tank body 5 is generally 1.5-3.0 h.

Preferably, the filler 3 is honeycomb type filler, and is filled in layers, the height of each layer is 1m, and the pore diameter of the honeycomb is not less than 25 mm.

Preferably, the area of every other oxidation pond containing the filler 3 in the pond body 5 is generally not more than 25m²。

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
