[0002] Directly discharging sewage from production and life will lead to environmental pollution and waste of water resources. How to effectively and economically treat sewage becomes particularly important, and finding efficient and low-consumption sewage treatment technology has become a very valuable research topic. The flat ceramic membrane bioreactor is a water treatment technology that integrates biological treatment process and membrane separation process.
