Description
Technical Field
The utility model relates to a UASB technical field, especially a water distribution device.
Background
A UASB anaerobic reactor, namely an upflow anaerobic sludge blanket, consists of a sludge reaction zone, a gas-liquid-solid three-phase separator (including a settling zone) and a gas chamber. A large amount of anaerobic sludge is reserved in the bottom reaction zone, and sludge with good settling property and coagulation property forms a sludge layer at the lower part. The sewage to be treated flows into the anaerobic sludge bed from the bottom of the anaerobic sludge bed to be mixed and contacted with the sludge in the sludge bed, and the microorganisms in the sludge decompose the organic matters in the sewage and convert the organic matters into methane. The marsh gas is continuously discharged in the form of micro bubbles, the micro bubbles are continuously combined in the rising process to gradually form larger bubbles, sludge with thinner sludge concentration is formed at the upper part of a sludge bed due to the stirring of the marsh gas and rises together with water to enter a three-phase separator, and when the marsh gas touches a reflecting plate at the lower part of the separator, the marsh gas is folded to the periphery of the reflecting plate, then passes through a water layer to enter a gas chamber, is concentrated in the marsh gas in the gas chamber and is led out by a guide pipe. The solid-liquid mixed liquid enters a settling zone of the three-phase separator through reflection, sludge in the sewage is flocculated, particles are gradually increased, and the sludge is settled under the action of gravity. The sludge deposited on the inclined wall slides back to the anaerobic reaction zone along the inclined wall, so that a large amount of sludge is accumulated in the reaction zone, and treated effluent separated from the sludge overflows from the upper part of the overflow weir of the deposition zone.
The traditional water distribution device is positioned at the bottom of the USAB and adopts a perforation water distribution mode. The UASB anaerobic reactor can continuously generate anaerobic sludge in the running process. If the sludge is not discharged in time, the sludge can be accumulated slowly. After long-time operation, the sludge can block the water distribution device, and further the normal operation of the UASB system is influenced.
