Abstract

The invention relates to a three phase separator of an up flow type anaerobic reactor, which is composed of a cone diversion drum arranged on the upper end of a anaerobic reactor barrel, a gas hood arranged on the upper end of the cone diversion drum, a gas chamber is composed of the gas hood and a wide mouth of the cone diversion drum, a circular passage arranged between the lower end of the gas hood wall and the upper end of the cone diversion drum wall, a circular passage arranged between the lower end of the cone diversion drum wall and the upper wall of the anaerobic reactor barrel, a gas chamber with bigger volume and a bigger gas liquid separation interface is composed of a circular wide mouth on upper of the cone diversion drum and a cylinder gas hood, can reduce release rate of biogas and aqueous vapour entraining amount discharged from the reactor barrel, adopting the invention, gas in mixture liquor of gas, sludge and water can not enter into the settling zone barrel, gas can be separated and removed effectively to avoid gas leaking to the settling zone barrel to interfere solid-liquid separation effect.

Description

technical field [0001] The invention relates to a three-phase separator for an upflow anaerobic reactor. Background technique [0002] Compared with traditional aerobic biological treatment technology, anaerobic biological treatment technology has high organic matter load, does not require a large amount of dilution water; high purification efficiency; less nutrient requirement; no aeration, low energy consumption, and low operating costs It has strong adaptability to impact load and environmental conditions; it can produce biogas as clean energy for recycling; the sludge yield is low, and the generated biological sludge is easy to dehydrate; the reactor volume is small and the floor area is small, etc. It has been widely used in the treatment of medium and high concentration organic wastewater in light industry, chemical industry, pharmaceutical and other industries, and achieved good results. The most successful application at present is the upflow anaerobic sludge bed re...
