METHOD FOR TREATING WASTEWATER BIOLOGICALLY BY CONTINUOUSLY CYCLING AND REGENERATING POWDERED ZEOLITE IN THE BIOREACTOR

摘要

As anaerobic or anoxic, aerobic tank, and after a predetermined amount In the powdered zeolite in a series of biological treatment tank is composed of a sequence of the settling tank, depending on the flow of sewage and waste water, these powdered zeolites and sludge through each of the reaction tank, the biological by COD reduction, adsorption, denitrification, to perform dephosphorization and subsequently powdered zeolite is transferred along with the sludge economical biological sewage and waste water treatment method is naturally reproduced in each of the reaction vessel, the additional zeolite reproducing device to an external is very cost-effective and efficient sewage and waste water treatment method that can effectively handle sewage and waste water installation and without additional introduction of the biological treatment apparatus.
