药品和个人护理品（Pharmaceuticals and Personal Care Products, PPCPs）在城市污水中普遍检出，具有潜在生态风险和健康风险，是污水再生利用面临的难题。臭氧氧化是PPCPs去除的重要方法，但面临着利用效率低和氧化效果差等挑战。微米气泡具有比表面积大、气泡内压高、悬停时间长等优点，有望用于强化臭氧氧化效率。本研究旨在利用陶瓷膜实现臭氧微米气泡曝气，探明微米气泡曝气对臭氧传质和氧化的强化特性和机制，构建实际水样中臭氧微米气泡去除PPCPs效率快速指示指标模型，为污水再生臭氧氧化处理技术提供理论基础和技术支撑。利用陶瓷膜研发了微米气泡曝气方法，在0.14～0.19 MPa的气态压力条件下实现了微米气泡（40～80 μm）曝气。与毫米气泡相比，微米气泡曝气显著提高了液相臭氧平衡浓度（1.53～3.25倍）、表观传质速率（3.12～3.35倍）和羟基产率（2.67～3.54倍）；自由基掩蔽和动力学研究发现，微米气泡可同时强化臭氧传质和羟基产率，对难降解型污染物2,4-二氯苯氧乙酸（2,4-dichlorophenoxyacetic acid，2,4-D）的降解贡献率分别为35.8%～45.9%和54.1%～64.2%。其中，臭氧传质强化是提高羟基产率的主要原因，而界面效应贡献较低。不同操作条件对臭氧微米气泡曝气氧化效率影响较小，如进气压力（0.14～0.18MPa）、进气浓度和流量，但水质条件（无机碳和腐殖酸）对氧化效率影响较大，羟基抑制作用尤其明显。微米气泡曝气对臭氧氧化PPCPs具有显著的强化氧化效果，对较难降解的PPCPs强化作用尤其明显。碱性pH可促进微米气泡曝气臭氧氧化效率，对易降解型和难降解型PPCPs提升较显著（1.32～1.87倍），对一般降解型PPCPs提升较小（1.14～1.24倍）；高浓度碳酸根离子造成难降解PPCPs去除效率降低2.3%～3.4%，低浓度腐殖酸对易降解型PPCPs的抑制效果明显（64.8%），而高浓度腐殖酸对所有PPCPs具有明显抑制效果。河水基质中的去除效率仅有轻微下降，二级出水基质中氧化抑制效果明显，一般降解型和难降解型PPCPs的氧化抑制效果更为明显（34.3%～65.6%），易降解型PPCPs的羟基氧化贡献率下降到35.7%。根据臭氧微米气泡曝气过程中不同实际水样的溶解性有机碳、紫外吸收和荧光变化特性，评价其与PPCPs去除效率的相关关系，可建立单段式或两段式线性替代模型。结果发现，UV适合作为一些成分相对简单实际水样的替代性指标（R2>0.986），而水质越复杂，三维荧光作为替代性指标的优势越大（R2>0.981）。

Pharmaceuticals and Personal Care Products (PPCPs) are commonly detected in urban sewage, posing potential ecological and health risks, and presenting a challenge to sewage reuse. Ozone oxidation is an important method for removing PPCPs, but faces challenges such as low utilization efficiency and poor oxidation effects. Microbubbles have advantages such as a large surface area, high internal gas pressure, and long suspension time, making them promising for enhancing ozone oxidation efficiency. This study aims to use ceramic membranes to achieve ozone microbubble aeration, explore the enhancement characteristics and mechanisms of microbubble aeration on ozone mass transfer and oxidation, and establish a rapid indicator model for microbubble ozone removal efficiency of PPCPs, providing a theoretical basis and technical support for sewage treatment using ozone oxidation technology.A microbubble aeration method was developed using ceramic membranes, which achieved ozone microbubbles (40-80 μm) aeration under gas pressure conditions of 0.14-0.19 MPa. Compared to millimeter-sized bubbles, microbubble aeration significantly increased the liquid-phase ozone equilibrium concentration (1.53-3.25 times), apparent mass transfer rate (3.12-3.35 times), and hydroxyl radical yield (2.67-3.54 times). Through studies on radical shielding and competitive kinetics, it has been found that microbubbles can simultaneously enhance ozone mass transfer and hydroxyl radical production, with contributions to the degradation of the resistant pollutant 2,4-dichlorophenoxyacetic acid ranging from 35.8% to 45.9% and 54.1% to 64.2%, respectively. Ozone mass transfer enhancement was found to be the main reason for the increase in hydroxyl radical yield, while the interface effect of microbubbles had a lower contribution to hydroxyl radical yield. Different operating conditions had little effect on the efficiency of microbubble aeration ozone oxidation, such as inlet pressure (0.14-0.18 MPa), inlet ozone concentration, and inlet flow rate. However, water quality conditions (inorganic carbon and humic acid) had a significant effect on microbubble aeration ozone oxidation efficiency, with a particularly significant inhibitory effect on hydroxyl radicals.Microbubble aeration significantly enhances the oxidation of PPCPs by ozone, especially for moderately reactive and resistant PPCPs. Alkaline pH promotes the efficiency of microbubble aeration ozone oxidation, with a more significant enhancement observed for both reactive and resistant PPCPs (1.32-1.87 times) than for moderately reactive PPCPs (1.14-1.24 times). High concentrations of carbonate ions reduce the removal efficiency of resistant PPCPs by 2.3-3.4%, while low concentrations of humic acid significantly inhibit the removal of reactive PPCPs (64.8%). High concentrations of humic acid inhibit the removal of all types of PPCPs. The removal efficiency in river water matrices only slightly decreases, but significant oxidation inhibition is observed in secondary effluent matrices, especially for moderately reactive and resistant PPCPs （34.3%-65.6% inhibition）, with a decrease in the contribution of hydroxyl oxidation for reactive PPCPs to 35.7%.Based on the changes in dissolved organic carbon, UV absorption, and fluorescence characteristics of different actual water samples during the ozone microbubble aeration process, a single-stage or two-stage linear substitution model can be used to evaluate the correlation between the removal efficiency and PPCPs. The results show that UV is suitable as a substitution index for some relatively simple components of actual water samples (R2>0.986), while the more complex the water quality, the greater the advantage of using three-dimensional fluorescence as a substitution index (R2>0.981).
