AUTOTHERMAL THERMOPHILIC AEROBIC DIGESTOR FOR WASTE WATER TREATMENT

摘要

PURPOSE: A self-heating high temperature aerobic digestion apparatus for processing wastewater is provided to improve the decomposition efficiency of organic materials in the wastewater by uniformly diffusing aerobic microorganisms in an aerobic digester. CONSTITUTION: A self-heating high temperature aerobic digestion apparatus for processing wastewater includes an aerobic digester, an air supplying unit(110), and a cylindrical guiding member(120). Air nozzles discharging air and supplying lifting force for circulating wastewater are installed on the air supplying unit with the constant interval. An Inner protrusion(122) in a spiral form is installed on the inner wall surface of the guiding member for sucking up the wastewater on the inner bottom of the aerobic digester by an air lift phenomenon, after discharging the air from the air nozzles. The air supplying unit includes an air supplying pipe(114) and the air nozzles(116).
