摘要

ANAEROBIC PURIFICATION DEVICE FOR WATER PURIFICATION, USE OF ANAEROBIC PURIFICATION DEVICE AND METHOD OF OPERATING AN ANAEROBIC PURIFICATION DEVICE AS WATER SERVED. The present invention relates to an anaerobic effluent purification device including: a reactor tank; input devices for introducing tributary into the tank; water collecting device for collecting purified water; a gas collection system for collecting gas from a fluid contained in the reactor; a gas-liquid separation device; a riser for passing liquid into the raised gas separation device caused by gas collected in the gas collection system; a down tube to take up liquid and slurry from the separator within the lower section of the tank. According to the invention, this device is characterized by the fact that it is set to define, in the descending pipe at the liquid surface level, a head pressure of at least approximately 1.4 m of water column (about 0 , 14 bar). The invention also relates to a method for anaerobic purification device for effluent purification.
