CONTROL OF ACTIVATED SLUDGE WASTEWATER TREATING PROCESS FOR ENHANCED PHOSPHORUS REMOVAL |
摘要 |
<p>An improved method of operating an activated biomass process wherein influent and activated biomass are initially contacted under anaerobic conditions to form a mixed liquor, the mixed liquor is subsequently oxygenated, thereafter activated biomass is separated from the mixed liquor and at least a portion of the separated biomass is introduced into the initial contacting step. The improved method comprises maintaining both the F/M ratio and the BOD/P ratio within particular ranges, preferably relative to each other.</p> |
