To guide the practical application of ozonation coupled with tubular ceramic membranes (TCMs), the performance and the mechanism of mitigated membrane fouling by pre-ozonation-filtration (Pre-O/F) and in-situ ozonation-filtration (in-situ-O/F) were investigated. The in-situ-O/F mode exhibited a rejection performance 1.19 times better than that of Pre-O/F for effluent organic matter (EfOM) removal, but less membrane fouling mitigation. The backwashing efficiency of the in-situ-O/F mode was better than that of Pre-O/F, because backwashing loosened the in-situ-O/F membrane fouling layer and made it easier to remove by backwashing. SEM-EDX measurements were used to identify the components of the inorganic, organic, and biofouling membrane fouling layers. In Pre-O/F mode, EfOM, extracellular polymeric substances, and microorganisms in the effluent were destroyed by ozonation before filtration. In in-situ-O/F mode, the adhesion between irreversible membrane fouling and the pores/surfaces of TCMs was destroyed by ozonation, thus converting the irreversible membrane fouling to reversible membrane fouling. This led us to propose the process strategy of filtration coupled with ozonation for reclaimed water treatment. Pre-O/F is suitable for use in the treatment of large amounts of wastewater in short times because of the high-water flux. The in-situ-O/F mode is more suitable for normal use because of its lower operating cost and higher efficiency.

为了指导臭氧化与管状陶瓷膜（TCM）结合的实际应用，通过预臭氧化过滤（Pre-O / F）和原位臭氧化过滤（原位- O / F）进行了调查。该原位-O / F模式表现出抑制性能比的预O / F更好1.19倍为流出物的有机物质（EFOM）的去除，但小于膜减轻结垢。原位-O / F模式的反洗效率要优于Pre-O / F，因为反洗会使原位松动-O / F膜结垢层，使其更容易通过反冲洗去除。SEM-EDX测量用于确定无机，有机和生物污染膜污染层的成分。在Pre-O / F模式下，过滤前，臭氧处理可破坏废水中的EfOM，细胞外聚合物和微生物。在原位-O / F模式下，不可逆膜结垢与TCM的孔/表面之间的粘附力通过臭氧化作用被破坏，从而将不可逆膜结垢转化为可逆膜结垢。因此，我们提出了过滤与臭氧化相结合的再生水处理工艺策略。由于水通量高，Pre-O / F适合在短时间内处理大量废水。在原位-O / F模式具有较低的运行成本和较高的效率，因此更适合正常使用。
