Abstract

The invention discloses a UASB reactor for sewage treatment, the UASB reactor includes a UASB reactor pool and a supporting rod located in the central axis of the UASB reactor pool, the supporting rod is connected with a water distribution pipe, the water distribution pipe is installed horizontally, the supporting rod is vertically installed, the UASB reactor also includes a water discharge groove, and the drainage groove is located in the UASB reactor pool and at the upper part of the UASB reactor pool. The structure of the UASB reactor is simple, the effect of water distribution is good, the structure of a filler frame is stable, and the effect of water inletting, water discharge, exhaust and sludge discharge can be obviously improved.

Description

Technical field [0001] The invention relates to the technical field of industrial wastewater treatment, and in particular to a UASB reactor for sewage treatment. Background technique [0002] The wastewater from the UASB reactor is introduced into the bottom of the reactor as evenly as possible, and the wastewater passes upward through a sludge bed containing granular sludge or flocculent sludge. Anaerobic reaction occurs in the process of contact between wastewater and sludge particles. The biogas (mainly methane and carbon dioxide) produced in the anaerobic state causes internal circulation, which is beneficial to the formation and maintenance of granular sludge. Some of the gas formed in the sludge layer adheres to the sludge particles, and the attached and unattached gases rise to the top of the reactor. The sludge rising to the surface hits the bottom of the gas launcher of the three-phase reactor, causing the sludge flocs attached to bubbles to degas. After the bubbles a...
