Improved expanded granular sludge bed (EGSB) reactor and method utilizing improved EGSB reactor to improve organic wastewater treatment efficiency

Abstract

An improved expanded granular sludge bed (EGSB) reactor and a method utilizing the improved EGSB reactor to improve organic wastewater treatment efficiency belong to the technical field of sewage treatment. A flow-guiding flow-disturbing device is additionally arranged in a sludge bed area of a traditional EGSB reactor and is composed of an upper arc-shaped horn opening (2), a lower arc-shaped horn opening (2) and a flow-guiding barrel (3). The arc-shaped horn openings (2) comprise an upper opening (2-1), a lower opening (2-2) and a supporting wall (2-3). A lower port of the flow-guiding barrel (3) is connected with the upper opening (2-1) of the lower arc-shaped horn opening (2), and the distance of the top end of the flow-guiding barrel (3) and the bottom end of the arc-shaped horn opening (2) located at the upper end of the flow-guiding barrel (3) is 1 / 3 to 2 / 3 that of the lower opening (2-2) of the upper arc-shaped horn opening (2) and the upper opening (2-1) of the lower arc-shaped horn opening (2). The processing method has the advantages of being simple to operate, safe, reliable, economical and energy-saving and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a water treatment device and a method thereof, in particular to a device for adding a diversion and disturbance device inside an EGSB reactor to improve the hydraulic flow state so as to improve the treatment capacity of organic waste water, and to use the device to improve the treatment capacity of organic waste water. Methods of water treatment.
