Description

Anaerobic reaction device for wastewater treatment

Technical Field

Background

Anaerobic biochemistry is an efficient multistage internal circulation anaerobic reaction water treatment mode, and the anaerobic biochemical device has the characteristics of small occupied area, high organic load, strong impact resistance, stable performance and simpler operation and management. The anaerobic device is suitable for treating organic high-concentration wastewater and has the advantages of high treatment efficiency and good treatment effect. Among them, the tank body in the anaerobic biochemical reaction device is an important device, and the traditional tank body is roughly classified into a polyethylene storage tank, a polypropylene storage tank, a glass fiber reinforced plastic storage tank, a ceramic storage tank, a rubber storage tank, a stainless steel storage tank and the like. In recent years, PP is widely used because of its advantages of light weight, corrosion resistance, no leakage, etc.

When the tank body is used for sewage treatment, the wastewater is uniformly introduced into the bottom of the tank body through the water distribution device, and the sewage upwards passes through a sludge bed containing granular sludge or flocculent sludge; the anaerobic reaction occurs during contact between the wastewater and the sludge particles. Biogas (mainly methane and carbon dioxide) produced under anaerobic conditions causes internal circulation, which facilitates the formation and maintenance of granular sludge. Some of the gas formed in the sludge blanket adheres to the sludge particles and rises toward the top of the tank, and the sludge rising to the surface strikes the bottom of the gas baffle of the three-phase separator, causing degassing of the sludge flocs adhering to the bubbles. After the bubbles are released, sludge particles are precipitated on the surface of a sludge bed, gas is discharged through the exhaust mechanism, and sewage subjected to anaerobic biochemical treatment is discharged to the water outlet through the overflow weir. The important ring is to introduce the sewage into the bottom of the tank body as uniformly as possible, but the current commonly used water distributors are difficult to meet the requirements, and the uniformity of water distribution is still to be improved.
