| 摘要 |
The present invention discloses an influent wastewater injection device suitable for upflow anaerobic sludge bed (UASB) reactors, with unsettled sewage and under sub-mesophilic temperatures in a sustainable way, comprising:
- a feeding wastewater tank, located outside the reactor and above the reactor water level, having a volume ranging from 0.5 to 1.5% of the total reactor volume for generating wastewater pulses by gravity, the feeding tank being connected to said reactor by means of
- an influent flow distribution manifold, that connects downwards the feeding tank at one end with
- al least one string with nozzles at a second end, the string having a valve automatically controlled by the water level in the feeding tank that generates a wastewater flow through the string that is released inside the reactor through the injection nozzles in the form of high flow pulses by gravity through the sludge bed, equivalent to a maximum upwards liquid velocity in the reactor from 6 to 12 m/h. |
