Built-in vertical flow precipitation type anaerobic reactor

Abstract

The invention discloses a built-in vertical flow precipitation type anaerobic reactor.The built-in vertical flow precipitation type anaerobic reactor is characterized in that a separation cover is arranged above a three-phase separator, a flow guide barrel is arranged on the top of an anaerobic reactor body, the separation cover comprises a body and an extension portion, the extension portion is fixed to the top of the body, the flow guide barrel and the lower side of the body are communicated with each other via the extension portion to form a gas and water ascending region, the extension portion partially extends into the flow guide barrel, is distanced from the top of the anaerobic reactor body to form a gas removal region and is distanced from the inner wall of the flow guide barrel to form a mud and water descending region, a second biogas exhaust pipe is connected with the top of the flow guide barrel, a vertical flow precipitation separation region is formed between the body and the top of the anaerobic reactor body, and a water outlet pipe is connected with the upper portion of the vertical flow precipitation separation region.The built-in vertical flow precipitation type anaerobic reactor has the advantages that the built-in vertical flow precipitation type anaerobic reactor is simple in structure, the problem of mud in water drained from existing anaerobic reactors can be solved, and follow-up sewage treatment load can be relieved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a built-in vertical flow sedimentation anaerobic reactor. Background technique [0002] In wastewater anaerobic biological treatment reactors, there is often the problem of effluent with mud, resulting in high concentrations of organic matter and suspended solids SS in anaerobic effluent, causing sludge loss and increasing the load of subsequent treatment. The anaerobic biogas is not completely separated from sewage and sludge, resulting in a low recovery rate of biogas. Sludge in the anaerobic reactor is easy to deposit at the bottom of the reactor, and the reactor is prone to dead zones, sludge compaction or calcification, resulting in low activity of anaerobic sludge to produce SMA. In order to improve the treatment efficiency of the anaerobic reactor and provide the SMA activity of the anaerobic sludge, the present invention is thus developed. Conten...
