The invention discloses a municipal sludge hydrothermal carbonization pressure filtrate nanotube up-to-standard treatment process, and relates to the technical field of municipal sludge treatment. The invention discloses a sludge hydrothermal carbonization press filtrate nanotube up-to-standard treatment process. The process comprises the following steps: press filtrate enters an adjusting tank; carrying out a coagulation reaction, and then carrying out solid-liquid separation; carrying out nitrogen removal by denitrification on the supernate and the reflux liquid of the secondary sedimentation tank; effluent enters an anaerobic tank for hydrolytic acidification; then carrying out denitrification nitrogen removal, and enabling effluent to enter an aerobic tank; carrying out sludge-water separation on effluent of the aerobic tank through a secondary sedimentation tank, and carrying out advanced oxidation reaction on supernate; oxidized effluent enters an A/O biological filter to be degraded. The treatment proc
