Adopting a 60 m3/d micro-flocculation flat ceramic membrane short process water purification process,simulating engineering operating parameters,conducting high flux operation testing and effectiveness research on the raw water of the Yangtze river.The results show that the process can operate stably under high throughput conditions of 100 LHM,with maintenance clean-ing cycle of 5~7 days and the TMP endpoint controlled within 35 kPa.The short process controls the turbidity of the effluent below 0.05 NTU,and the removal rates of CODMn,iron ions,and alu-minum ions are 49.9%,94.8%,and 89.8%,respectively.The average water production rate is 94.6%~97.5%,indicating stable effluent performance.The coupled ozone process can adapt to various raw water switching conditions.
