Abstract

The invention belongs to the technical field of sewage treatment equipment, and relates to a UASB anaerobic reactor automatic flushing method and a water distribution system thereof. The water distribution system comprises a water distribution header pipe and water distribution branch pipes; The water distribution header pipe annularly surrounds the outer part of the anaerobic reactor; and the water distribution branch pipes are arranged at the bottom of the anaerobic reactor, and two ends of each water distribution branch pipe are connected with the water distribution header pipe. The automatic flushing method comprises the following steps of S1, pipeline pressure detection, S2, blocked branch pipe separation and S3, flushing. The water distribution header pipe is arranged outside the reactor, the two ends of each water distribution branch pipe can supply water, the head loss is small, and the water distribution uniformity is guaranteed; The automatic flushing system adopts a water supply and flushing separated structure, so that water supply is not affected during flushing, the reactor does not need to be shut down, and meanwhile, the automatic flushing system provides basic guarantee for unmanned and automatic operation of the UASB anaerobic reactor.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and relates to an automatic flushing method of a UASB anaerobic reactor and a water distribution system thereof. Background technique [0002] The upflow anaerobic sludge bed reactor is an anaerobic biological method for sewage treatment, also called upflow anaerobic sludge bed, English abbreviation UASB (Up-flow Anaerobic Sludge Bed / Blanket). Its characteristic is that the sewage passes through the UASB from bottom to top, and there is a high-concentration and high-activity sludge bed at the bottom of the reactor, where most organic pollutants in the sewage are degraded into methane and carbon dioxide through anaerobic fermentation. [0003] The UASB anaerobic reactor is mainly composed of a water distribution system, a three-phase separator, an effluent collection system, and a sludge discharge system. The rational design of the water distribution system is crucial to the go...
