A METHOD FOR RAPID START-UP OF MICROBIAL GRANULATION IN WASTEWATER BIOTREATMENT PROCESS

摘要

There is disclosed herein a method of accelerating the growth of aerobic granules, comprising the step of adding: (a) one or more aggregating signalling compounds or precursors thereof; and/or (b) crushed aerobic granular biomass, to an activated sludge, wherein: (i) the amount of the one or more aggregating signalling compounds is equivalent to an amount extracted from an aerobic granular biomass that is about 1 wt% to about 10 wt% of the total estimated dry biomass in the activated sludge; and (ii) the amount of the crushed aerobic granular biomass is in an amount of from about 1 wt% to about 10 wt% of the total estimated dry biomass of the activated sludge.
