Embodiment Construction

[0015] Such as figure 1 As shown, the U-shaped anaerobic bioreactor of the present invention mainly includes a tank body 1, a water distribution system 2, a backflow system 3, a backwash system 4, a sludge discharge system 5 and a water outlet system 6. The pool body 1 adopts a reinforced concrete structure, and the whole structure is a U-shaped structure, which is a combination of a square area at the front and a semicircular area at the rear. The U-shaped structure solves the construction difficulties caused by the large pool capacity and long pool shape in civil construction. There is a partition wall 7 in the middle of the pool body 1, which divides the square area at the front of the U-shaped pool body 1 into two areas: a water distribution area 8 and a water outlet area 10. Water outlet system 6 and mud discharge system 5 are arranged. In the water distribution area 8, the sludge and sewage are fully mixed, and the water intake area is where the most gas is produced. ...

Abstract

The invention provides a U-shaped low speed anaerobic reactor which comprises a tank body, a water distribution system, a reverse-flow system, a back-washing system, a sludge discharging system and a water outlet system, wherein the tank body is a U-shaped structure and is divided into a front square area and a rear semi-circle area; a partition wall is arranged in the middle of the front square area of the tank body and separates the front square area into a water distribution area and a water outlet area, wherein the water distribution area is internally provided with the water distribution system; the water outer area is internally provided with the water outlet system and the sludge discharging system; the rear semi-circle area of the tank body is also internally provided with a semi-circle partition wall; the back-washing system is connected with the water distribution system; the reverse-flow system is connected between the bottom of the water outlet area and the top of the water distribution area; the sludge discharging system is arranged at the bottom of the water outlet system; and a marsh gas separation system is arranged above the whole tank body. The U-shaped low speed anaerobic reactor has anti-blocking function, high processing efficiency and stable quality of treated water, can treat multiple high-concentration waste water, is stable in running, has long service life and is convenient to operate and run.

Description

technical field [0001] The invention relates to an anaerobic reactor used in the biochemical treatment stage of industrial sewage treatment, belonging to the technical field of water treatment. Background technique [0002] The various reactors used at this stage can be classified as high, medium and low speed anaerobic reactors. Anaerobic reactors with a height of less than 10 meters and an ascending flow rate between 0.5-1.0 m / hour are classified as medium-speed anaerobic reactors, and the COD volume load of medium-speed anaerobic reactors is usually less than 5KgCOD / m 3 .d, flocculent sludge can be used for start-up and operation. The medium-speed anaerobic reactor occupies a moderate area, saves investment, and is convenient to operate, but the disadvantage is that it cannot be applied to high-concentration water quality and sewage with poor biodegradability, and the anaerobic sludge in the system is easy to lose. The high-speed anaerobic reactor is represented by the ...
