The invention provides a composition and a method for removing new pollutants in sludge or sewage, and belongs to the technical field of sewage or sludge treatment. The composition includes a persulfate and a catalyst iron amino acid chelate. As an active catalyst of persulfate, the amino acid chelated iron can catalytically activate the persulfate placed in the new pollutants to generate persulfate free radicals, so that the persulfate free radicals oxidize and degrade the pollutants in the new pollutants. In addition, the molecular structure of the amino acid chelated iron is close to the natural form of iron in a living body, the addition of excessive amino acid chelated iron does not cause harm to sludge and sewage, and plants in the sludge or sewage can be promoted to accelerate the chlorophyll formation speed, improve photosynthesis, promote seedling strengthening and increase the yield. The composition and the method provided by the invention have the advantages that the raw material cost is low, the c
