摘要:
A wastewater treatment system having a first solid-liquid separation unit, a membrane aerated biofilm (MABR) reactor, a second solid-liquid separation unit and an anaerobic digester. Waste sludges from the solid-liquid separation units are treated in the anaerobic digester. The solid-liquid separation unit preferable comprises a micro-sieve. The treatment system may also comprise an aerated contact tank with a hydraulic retention time of 6 hours or less. Optionally, the MABR may comprise a membrane filtration unit.
