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 SBR reactor, a secondary SBR 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.

A biotrickling filter for treating waste gas including a waste gas inlet, packing layers, a spray pipe, a spray liquid storage tank, and a waste gas outlet. The waste gas passes through a first packing layer after passing through the waste gas inlet and then passes through a second packing layer after changing the flow direction at the bottom of the first packing layer; the flow directions of the waste gas in the first packing layer and the second packing layer are opposite to form a cross-flow structure; the two different flow directions of the waste gas form a cross-flow unit, and two or more cross-flow units form the biotrickling filter.
