APPARATUS AND METHOD FOR ANAEROBIC WASTEWATER TREATMENT WITH MEMBRANE DISTILLATION

摘要

Disclosed is an apparatus and method for anaerobic wastewater treatment, which combines membrane distillation and biological treatment to improve treated water quality, performs anaerobic treatment to the wastewater to generate bio-gas and effectively restrain contamination of a membrane surface. The apparatus comprises a bio-reactor, submerged membrane modules, rotary disks and fluidizable media, wherein the bio-reactor is configured to give a space for filtration and biological treatment of wastewater and operated under an anaerobic condition, wherein the modules are provided in the bio-reactor to filter the wastewater, and wherein the rotary disks are provided at both sides of the module to induce turbulence of the wastewater and moving of the fluidizable media, wherein a channel is provided in the modules so that a cooling water flows therein, moisture of the wastewater is evaporated due to a temperature difference of the wastewater and the cooling water, moved to the channel.
