Process for treatment of organic contaminated water

摘要

The present invention may be used in methods for treatment of drinking water contaminated with algal metabolites. An inflow of water in a drinking water treatment facility may have multiple types of algal metabolites wherein each algal metabolites has a concentration of less than 20 µg/l. The water may contain indigenous bacteria that may serve as a bioreactor inoculum. The water may be dosed with a biodegradable electron donor at a concentration of less than 7 mg/l to form water, electron donor solution. The water, electron donor solution may be processed through a fixed-bed bioreactor for an empty bed bioreactor contact time of less than 30 minutes. An effluent of the fixed-bed bioreactor may have an algal metabolite concentration for each algal metabolite of less than 10 ng/l.
