On the Process Technology of production of inoculum sludge for UASB reactor

摘要

The present Invention relates to Procedure to produce inoculum from anaerobic granular sludge of Waste Water sewage treatment plants or other sources faceCterizado comprises the steps of: a) feed in Continuous aqueous sludge with a load of 0.5 5 kg / M3D TSS (total suspended Solids per cubic meter of reactor, preferably of Type Upflow sludge bed; (b) subjecting the sludge to a stage of anaerobic fermentation,Under the following conditions: Ambient temperature to 40C Hydraulic retention time of 1 to 5 days; Velocity integral (Recirculation) of 0.01 to 3M / hWith or without Slow stirring; (c) retain solids in the Reactor during a time of 20 to 60 days until the material change to a grainy appearance; (d) the product in a sediment Chamber of reposWhere is Thick or between 3 and 6 percent in Mass for use as inoculum.
