APPARATUS AND METHOD FOR ANAEROBIC WASTEWATER TREATMENT WITH MEMBRANE

摘要

The present invention relates to an anaerobic wastewater treatment apparatus having a membrane and a method thereof capable of generating biogas by anaerobically treating wastewater and also effectively preventing the contamination on the surface of a separation membrane. The anaerobic wastewater treatment apparatus having a membrane according to the present invention comprises an anaerobic bio-reactor for filtering and removing contaminants in wastewater while anaerobically digesting the wastewater; an anaerobic membrane bio-reactor for filtering, in a separation membrane module, wastewater discharged from the anaerobic bio-reactor and providing a room for anaerobically digesting wastewater; a submerged separation membrane module contained in the anaerobic membrane bio-reactor so as to filter wastewater; a rotating disk contained in the submerged separation membrane module and inducing the turbulence of wastewater by rotating; and second floating filter media contained in the anaerobic membrane bio-reactor and floating according to the flow of wastewater so as to detach contaminant materials from the surface of the separation membrane module.
