摘　　要：为了解决TiO2光催化耦合陶瓷超滤膜工艺优化过程中水质（CODMn）最优参数与水量（膜通量）最佳参数间不一致的问题，引用矩阵分析法对该多指标耦合工艺正交试验的结果进行优化。首先，构建了正交试验的层结构矩阵。尔后，将各层矩阵相乘得出试验指标值的权矩阵，并计算得出影响试验结果的各因素各水平的权重。最后，均分水质与水量的影响，确立了综合权重，根据综合权重的大小，确定各因素对响应值影响的主次顺序与耦合工艺的最佳运行参数。结果显示：在TiO2浓度为0．5g/L，曝气量5L／rain，跨膜压差0．15MPa，膜面流速2．0m／s的情形下，耦合工艺能兼顾出水水质和产水量的影响，实现工艺的最佳运行。In order to solve inconsistent optimum parameters of water quality （ CODMn ） and water production （membrane flux）during the TiO2 photocatalytic oxidation coupling ceramic ultrafiltration membrane process, matrix analysis method was introduced to optimize multi-index orthogonal test results. Initially, the layer structure matrix of orthogonal test was constructed. Then, the matrix of each layer is multiplied to obtain the weight matrix of the test index value, and the weight of each factor influencing the test result is calculated. Eventually, the influence of water quality and water quantity is established, and the comprehensive weight is established. According to the size of the comprehensive weight, the optimal order of the impact of each factor on the response value is determined. The results indicated that the best operation of the coupling process taking into account of effluent quality and water production can be achieved in the presence of TiO2 concentration of 0. 5 g/L, aeration rate of 5 L/min, a transmembrane pressure difference of 0. 15 MPa and a membrane velocity of 2. 0 m/s.
