Method and Apparatus of Biological Nitrogen and Phosphorus Removal from SBR

摘要

The present invention is biological nitrogen and phosphorus removal of the sequencing batch reaction tank for biologically in the aqueous phase concentration of the organic low to be able to remove nitrogen and phosphorus at the same time, a method and relates to an apparatus, a biological nitrogen and phosphorus removal of such continuous batch reactor method and the apparatus, or to occur after the release of the release is stored separately from the NO ₃ -N in the effluent of a predetermined amount to prevent a phenomenon in which deterioration by the NO ₃ -N, and phosphorus in the sewage injected into the raw water first, or , organic matter and nutrients from the lower organic loading wastewater characteristics, such as can be effectively removed by reducing the inhibition of NO ₃ N for the release of phosphorus to form the cover to the precipitated microorganism inside the sequencing batch reaction tank with nitrogen, and which have the same as the country that can be removed so that the effect will be.
