Membrane gas-water mixed continuous cleaning device and cleaning method in membrane bioreactor

The invention discloses a membrane gas-water mixing continuous cleaning device in a membrane bioreactor and a cleaning method, and belongs to the technical field of sewage treatment equipment. The device comprises an aeration pipe assembly and a flushing water pipe assembly. Aeration holes are formed in the aeration pipe assembly, and flushing water holes are formed in the flushing water pipe assembly. Gas can be output to the membrane to be cleaned through the aeration holes; through the flushing water hole, flushing water can be output to the membrane to be cleaned; under the combined action of gas and water, the membrane to be cleaned can be cleaned in a continuous working state. The method is realized based on the device. According to the device and the method, the membrane applied in the membrane bioreactor can be cleaned in the running process of the membrane bioreactor, and the running of the membrane bioreactor is not interrupted, so that the membrane bioreactor can stably run for a long time; and the
