The system mainly includes a reaction tank, a membrane module, a macroporous gas distribution device, low-temperature pyrolysis biochar. The application of the process to sewage treatment shows that: under the conditions that the hydraulic retention time is 3.2-7.2 h, the membrane flux is 12.0-17.8 L/m2/h, and the sludge concentration of 7.2-15.6 g/L, multiple objectives of promoting organic micropollutants (OMPs) biotransformation, accelerating methane production and strengthening membrane fouling control were achieved.
