Description

A high-efficiency anaerobic reactor for high-concentration chemical wastewater

technical field

The utility model belongs to the technical field of sewage treatment equipment, in particular to a high-efficiency anaerobic reactor for high-concentration chemical wastewater.

Background technique

UASB reactors are generally used for high-efficiency anaerobic reactors for high-concentration chemical wastewater. UASB reactors are composed of three parts: sludge reaction zone, three-phase separator and gas collection chamber, and a large amount of anaerobic sludge is left in the bottom reaction zone. , the sludge with good sedimentation performance and coagulation performance forms a sludge layer in the lower part, and the sewage to be treated flows in from the inlet pipe at the bottom to mix and contact with the sludge in the sludge layer, and the microorganisms in the sludge decompose the sludge in the sewage The organic matter is converted into biogas, and the biogas is continuously released in the form of tiny bubbles. The tiny bubbles are constantly merging in the process of rising, and gradually form larger bubbles. On the upper part of the sludge layer, due to the agitation of the biogas, a sludge concentration is formed. The thin mud-water mixture and the mud-water mixture mixed with biogas bubbles rise together into the three-phase separator. The biogas is collected by the gas-collecting hood of the three-phase separator and then enters the gas-collecting chamber. The biogas in the air chamber is discharged, and the mud-water mixture enters the sedimentation area through the gap between the gas collecting hood and the air-blocking plate, and the mud-water is separated. The supernatant is discharged from the outlet pipe at the top, and the sedimented sludge returns to the reaction under the action of gravity. Area.

The existing reactor has the following disadvantages: the sludge and wastewater cannot be fully contacted, and the organic matter in the sewage cannot be effectively decomposed, resulting in poor organic load capacity and low purification efficiency of the UASB reactor; at the same time, the sludge is easy to compact in the tank, Manual cleaning is required, and the cleaning cycle is long and labor-intensive.

Utility model content

The utility model provides a high-efficiency anaerobic reactor for high-concentration chemical wastewater in order to solve the existing problems. The collected biogas is rationally used to drive the agitator, which solves the problem of poor organic load capacity and low purification efficiency of the existing reactor. The problem of long cleaning period.

The utility model is realized through the following technical solutions:
