摘要: 综述了多年来国内外高度疏水膜应用于乳化油污水处理的研究及进展,简单介绍了含油污水处理及破乳方法,重点介绍了疏水膜分相机理和处理油水乳状液的破乳机理,讨论了影响疏水膜油水分离的因素。最后对今后的研究方向提出展望。Abstract: According to the high concentrations of industrial wastewater in chemical industrial park,through the analysis of problems existing in original ordinary A2 /O process,the improved A2 /O ditch process was put forward. The transformation operation results showed that the removal rate of COD NH3 -N TP was 57. 26% 76. 94% and 98. 36% respectively; and indexes of the effluent by the biochemical system achieved the first level standard : Integrated Wastewater Discharge Standard ( GB 8978 1996) .
