The invention discloses an anaerobic reaction device with an immersed membrane separation device. The anaerobic reaction device comprises an anaerobic reaction device body, the immersed membrane separation device, an aeration distribution device, a gas isolation shield, a shield water seal device, a biogas circulation pipeline, a blast equipment shield, blast equipment, a water inlet header pipe and a water production header pipe. Incoming water is fed into the anaerobic reaction device, the immersed membrane separation device continuously produces water under the driving action of hydraulic pressure difference, and a gas space in the anaerobic reaction device body, a gas isolation shield space, a biogas circulation pipeline space, a blast equipment shield space, a blast equipment pressurization cavity and a space in the aeration distribution device form a closed cavity. And the biogas forms closed circulation in the cavity and the water space of the anaerobic reaction device. An immersed membrane filtering device forms effective driving circulation through gas isolation and sealing, so that anaerobic condition guarantee without additional inert gas supplement is realized, and an immersed membrane works under the anaerobic biogas aeration condition.
Description
technical field [0001] The present application relates to the field of anaerobic reaction devices, in particular to an anaerobic reaction device with a submerged membrane separation device. Background technique [0002] The biochemical reaction device is a representative treatment device in water treatment. It mainly uses the absorption of nutrient substrates in the water body by microorganisms in the process of proliferation and growth to realize the pollution degradation of the water body. According to the type of microorganisms, it can be divided into aerobic reaction device, anoxic reaction device and anaerobic reaction tank. [0003] Anaerobic reaction devices are widely used in practical projects because of their high removal load and good impact resistance. Anaerobic colonies are a type of bacteria that are strictly limited by the amount of dissolved oxygen in water. If the dissolved oxygen content in the water is too high, the survival of anaerobic bacteria will be ...
