Abstract

The invention relates to an up flow type anaerobic reactor, which comprises a barrel of the reactor, a water distributor pipe arranged on the lower end of the barrel, a three phase separator composed of a cone diversion drum arranged on the upper end of the barrel and a gas hood arranged on the upper end of the cone diversion drum, a circular passage arranged between the lower end of the gas hoodwall and cone diversion drum wall, a circular passage arranged between the cone diversion drum and the upper wall of the barrel, a settling zone barrel arranged on the upper end of the reactor barrel, a drain trough arranged on top of the settling zone barrel, the combination of two circular passages can separate sludge with water, gas with water at different position, has good separating effect of gas, sludge, water, thereby avoiding the problem of return-sludge flow interfered by inlet flow because of mixed liquor ascent passage sharing one passage with return-sludge flow in a conventional three phase separator, the invention can keep liquid flow in settling zone steady, fluid state closing to laminar flow, has good solid-liquid separation effect.

Description

technical field [0001] The invention relates to 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 reactor (UASB). [0003] Wast...
