AI Technical Summary
Traditional biofilm methods suffer from low oxygen utilization efficiency, high energy consumption, and a single direction of oxygen and substrate transfer, making it impossible to achieve simultaneous anaerobic-aerobic cascade reactions in microorganisms.
A microcrystalline composite MABR membrane is used, and micro-nano composite microcrystals are enriched on the membrane surface through plasma treatment. The anaerobic-aerobic cascade reaction of the microbial community is realized by utilizing the partial pressure difference of O2/CO2. The plasma treatment also increases the polar groups on the membrane surface to fix the microcrystals, thereby improving oxygen utilization and biofriendliness.
It achieves low-energy consumption and high oxygen utilization rate of microbial synchronous cascade reaction, improves sewage treatment efficiency, and is particularly suitable for the synchronous digestion-denitrification treatment of high ammonia nitrogen sewage.
