Pulse water distribution device and water distribution method for UASB (anaerobic reactor)

Abstract

The invention discloses a pulse water distribution device and a water distribution method for a UASB (anaerobic reactor). The device mainly comprises a motor, a motor speed reducer, a cavity, a water intake device and a water discharge device, wherein the motor conveys power to the motor speed reducer through a shaft coupler, a rotating shaft and a water distribution plate are arranged in the cavity, the water intake device injects water into the cavity, and the water discharge device discharges the water in the cavity. According to the invention, pulse water distribution is realized by a mechanical method and the water intake connection mode is optimized, thereby improving the integral water distribution efficiency and greatly reducing the failure rate of water distribution pipeline.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a pulse water distribution device and a water distribution method for UASB. Background technique [0002] Anaerobic biological treatment technology (anaerobic reactor) 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. People have successively developed the second-generation anaerobic reactor represented by UASB, and the third-generation high-efficiency anaerobic reactor represented by EGSB, AFB, IC, etc., which have been widely used in practical engineering. For high-efficiency anaerobic reactors, it is not only necessary to separate the sludge retention time and hydraulic retention time, but also to maintain sufficient contact between the influent and the sludge. The mixing of sludge and wastewater in the anae...

Problems solved by technology

Due to the working environment of the water distributor, the water distribution pipes are often prone to blockage, and once the water distribution pipes are blocked, it is not easy to find out. Because most of the current water distribution pipes have dead corners at the corners, it is very difficult to clean them, which affects the normal operation of the anaerobic reactor.

[0003] Although the design of the water distribution pipe has been improved in Chinese patent applications No. 200620024297 and No. 200920043974, there are still problems such as uneven water distribution of UASB, easy blockage, insufficient hydraulic stirring power, and insufficient settlement time.
