Abstract
A nano zero valent iron biological coupling device for organic wastewater includes a continuous flow stirred reactor, a flocculation sedimentation device and a membrane bioreactor arranged in series. A nano zero valent iron feeding device is arranged in the continuous flow stirred reactor, a flocculant and a coagulant aid are arranged in the flocculation sedimentation device, and a microbial reaction liquid is arranged in the membrane bioreactor. A nano iron biological coupling process includes: S, placing the organic wastewater in the continuous flow stirred reactor, adding the nano zero valent iron, stirring and mixing; S, placing the organic wastewater treated after Sin the flocculation sedimentation device; S, placing the organic wastewater treated after Sin the membrane bioreactor and interacting with the microbial reaction liquid; S, performing a membrane separation on the organic wastewater treated after Sin the membrane bioreactor to obtain purified organic wastewater.
