Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an MVR-based energy-saving and environment-friendly sewage treatment equipment. Background technique [0002] With the increasingly serious problem of urban environmental pollution, the treatment and disposal of sewage and sludge as the main content of urban pollution control has gradually received more and more attention. The national urban sewage treatment capacity reaches 1.0×108m 3 / d, the annual sewage treatment capacity reaches 3.0×10 10 m 3 , the sludge output will reach 3.0×10 7 t (80% moisture content). With the increase of sewage treatment rate and treatment depth, sludge discharge is increasing at a rate of more than 10-15% per year, but supporting sludge treatment and disposal has not made great progress. Due to technical and policy reasons, most domestic urban sewage sludge is disposed of by landfill without harmless treatment, and the secondary polluti...
