A first aspect of the present invention relates to a digested sludge treatment apparatus for treating digested sludge generated by subjecting organic waste matter to anaerobic digestion, comprising: an apparatus for decarbonating the digested sludge; a removal apparatus for removing coarse contaminant particles from the digested sludge; and an apparatus for separating or concentrating crystals containing magnesium ammonium phosphate from the digested sludge after the digested sludge passes through the decarbonation apparatus and removal apparatus. Another aspect of the present invention relates to a digested sludge treatment apparatus for treating digested sludge generated by subjecting organic waste matter to anaerobic digestion, comprising: a crystallization reactor for precipitating magnesium ammonium phosphate from the digested sludge; a removal apparatus for removing coarse contaminant particles from the digested sludge; and an apparatus for separating or concentrating crystals containing magnesium ammonium phosphate from the digested sludge after the digested sludge passes through the crystallization reactor and coarse contaminant particles removal apparatus.
