Water distribution system for anaerobic reactor

Abstract

The invention discloses a water distribution system for an anaerobic reactor, comprising a support (1). A plurality of U-shaped water distribution pipes (2) are disposed on the support (1) and provided with a plurality of nozzles (3), and two adjacent nozzles (3) on branch pipes of the U-shaped water distribution pipes (2) are always on two sides of the corresponding branch pipe; water inlets of the U-shaped water distribution pipes (2) are connected with an inflow master pipe (5) respectively through corresponding inflow branch pipes (4), and the inflow master pipe (5) distributes water for the U-shaped water distribution pipes (2) in mechanical constant-pressure distribution manner. The U-shaped water distribution pipes herein enable uniform water distribution with no dead corner and good mud bed activity; a pressure backflushing system is added, blockage of the water distribution system and mud bed dead corners that are formed are eliminated, high efficiency and low energy consumption are achieved, anaerobic treatment effect is improved, significant environmental and economic benefits are achieved in the field of treatment of high-concentration organic wastewaters, and wastewater treatment cost is decreased by 8%.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a water distribution system for an anaerobic reactor with uniform water distribution and a pressure backwash mechanism. Background technique [0002] Anaerobic treatment technology is an advanced wastewater treatment technology that is energy-saving and efficient and can recover a large amount of biomass. At present, the existing domestic technology has the characteristics of high treatment load, low treatment power consumption, and low sludge production. It is widely used in urban life. Sewage and industrial wastewater treatment processes. The use of anaerobic reactor treatment can make the anaerobic bacteria multiply quickly, the time is short, the removal rate is high, the gas production rate is good, the operating cost is low, and the land occupation is small. However, the anaerobic reactors in the prior art all adopt pulsed water distribution, and the water distribution syst...

AI Technical Summary

Problems solved by technology

However, the anaerobic reactors in the prior art all use pulsed water distribution, and the water distribution system is a radial emission structure, which has defects such as uneven water distribution, easy blockage of the system, many dead spots in the mud bed, and low treatment rate.
