Description

ABR reactor

Technical Field

The utility model relates to an environmental protection equipment technical field especially relates to a sewage treatment plant ABR reactor.

Background

Anaerobic biological treatment is a treatment method which utilizes the metabolic characteristics of anaerobic microorganisms, takes reduced organic matters as hydrogen acceptors under the condition of not providing exogenous energy, and finally converts the organic matters into small molecular substances such as methane, carbon dioxide, water, hydrogen sulfide, ammonia and the like. Is widely used for treating high-concentration organic sewage. The ABR process is a process which obviously enhances the treatment effect by utilizing the characteristics of an anaerobic process and combining fluid dynamics. The existing ABR reaction equipment generally has short retention time, poor treatment effect and larger occupied area, so that the treatment cost is greatly improved.

Disclosure of Invention

In order to solve the above technical problem, the present invention provides an ABR reactor.

The purpose of the utility model is realized through the following technical scheme:

an ABR reactor comprises a reaction chamber, a baffle plate and a uniform water distribution pipe (6); the reaction chambers comprise three reaction chambers, namely a first reaction chamber (5a), a second reaction chamber (5b) and a third reaction chamber (5c), the three reaction chambers are connected in parallel, and the baffle plate comprises a vertical baffle plate (3) and a baffle plate (7) inside the reaction chambers; the middle parts of the three reaction chambers are respectively separated by a vertical baffle plate (3); the uniform water distribution pipe (6) is arranged at the bottom of the first reaction chamber.

Compared with the prior art, the utility model discloses an advantage can have as follows to one or more embodiments:

1. the ABR reactor can be designed according to the amount of treated water, so that the construction quality is ensured, and the investment cost is saved.

2. The ABR reactor has simple process flow, long retention time and stable water outlet, and does not need additional power.

3. The vertical baffle plates are arranged in the reactor, so that the contact time of anaerobic sludge and sewage is prolonged while the mixing and stirring effects are achieved, and the treatment efficiency is improved;

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1, the ABR reactor is of an integral structure, including: a reaction chamber, a baffle plate and a uniform water distribution pipe 6; the reaction chambers comprise three reaction chambers, namely a first reaction chamber 5a, a second reaction chamber 5b and a third reaction chamber 5c, the three reaction chambers are connected in parallel, and the baffle plate comprises a vertical baffle plate 3 and a baffle plate 7 in the reaction chamber; the middle parts of the three reaction chambers are respectively separated by a vertical baffle plate 3; the uniform water distribution pipe 6 is arranged at the bottom of the first reaction chamber.

The ABR reactor also comprises a water outlet 1, a gas outlet 2 and a shell observation hole; the water outlet 1 is arranged at the right upper side of the third reaction chamber 5c and is connected with the third reaction chamber 5 c; the air outlet 2 is arranged at the upper end of the water outlet 1; the casing observation hole is including three, is the first observation hole 4a of casing, casing second observation hole 4b and casing third observation hole 4c respectively, the first observation hole 4a of casing, casing second observation hole 4b and casing third observation hole 4c are parallel connection and arrange in the upper end of first reaction chamber 5a, second reaction chamber 5b and third reaction chamber 5 c.

The lower end of the uniform water distribution pipe 6 is provided with a water inlet, and the direction of the water inlet is downward.

The reaction chamber internal baffle plates 7 comprise three baffle plates, and are respectively arranged in the middles of the first reaction chamber 5a, the second reaction chamber 5b and the third reaction chamber 5 c.

The ABR reactor is integrated equipment.

The above embodiments, when in use:

the sewage to be treated is conveyed to the uniform water distribution pipe through a pipeline, the water inlet is arranged downwards, the sewage flows upwards slowly, and meanwhile, the sludge can be stirred upwards, so that the water is in full contact with the sludge. The water, the sludge and the gas which move upwards are separated under the action of the baffle plate, the sludge is prevented from falling back downwards, the water moves downwards again and upwards through the vertical baffle plate to enter the second reaction chamber for continuous reaction, the gas flows out through the gas hole in the top of the reaction chamber, finally, the clear water which is treated by the three reaction chambers flows out through the water outlet, and the gas is discharged through the gas outlet. Staff's accessible the sewage change in the reaction chamber is observed at any time to the casing inspection hole, guarantees the ABR reactor normal operating.

Although the embodiments of the present invention have been described above, the description is only for the convenience of understanding the present invention, and the present invention is not limited thereto. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
