摘要
An apparatus and a method for removing nitrogen and phosphorus from sewage by using sponge iron and activated sludge are disclosed herein. The apparatus comprises a raw tank, a pH adjusting tank, a primary SBBR reactor, a secondary SBBR reactor, an intermediate tank, and a discharge tank; by modification of sponge iron, preparation of composite filler, sludge inoculation and domestication, and sewage treatment, an effect of simultaneous denitrification and dephosphorization is achieved in one reactor using the combined action of sponge iron and activated sludge with high nitrogen and phosphorus removal efficiency.
