APPARATUS AND METHOD FOR ELIMINATING DISSOLVED SOLIDS AND SUSPENDED SOLIDES OF WASTEWATER BY MICRO BUBBLE

摘要

Disclosed is the foul/waste water treatment process and method that can simultaneously eliminate both dissolved solids ans suspended solids using microbubbles and, more particularly, to a foul/waste water treatment process and method that can simultaneously eliminate both suspended solids and at least one kind of dissolved solids such as soluble chemical oxygen deman, NH4+−N, NO2−−N, NO3−−N, PO43−−P, color causing organics and the like by supplying microbubbles generated with a surfactant(s) to the foul/waste water. The invented foul/waste water treatment process includes multiple flotation tanks in series for receiving foul/waste water to be treated, bubble generators for supplying microbubbles using surfactant solutions to the flotation tanks, and a waste bubble collector for removing waste microbubbles that have attached suspended and dissolved solides chemically and physically.
