摘　　要：本文以城市生活垃圾渗滤液处理系统反渗透产水为研究对象,采用模拟中试装置,考察不同气水比及填料层高度对反渗透产水pH值的影响。研究结果表明,吹脱可以有效地提高反渗透产水的pH值。此外,适当增加填料高度及气水比均可提高吹脱效果。值得注意的是,与填料高度相比,气水比对反渗透水p H值的影响更为明显,循环次数对反渗透产水pH值的影响较小。吹脱可少量去除反渗透产水中的氨氮,降低产水的氨氮浓度。This paper examines reverse osmosis water production within the treatment system of municipal solid waste leachate,employing an air stripping pilot-scale setup,it investigates the influence of varying gas-water ratios and packing layer heights on the pH of the reverse osmosis water.Thefindings suggest that air stripping effectively elevates the pH of the reverse osmosis water.Moreover,appropriately increasing both the packing height and gas-water ratio enhances this aeration effect.Notably,the impact of the gas-water ratio on the pH of the reverse osmosis water is more pronounced compared to packing height,while the number of cycles exhibits a relatively minor influence on the pH.Air stripping can remove some ammonia nitrogen of the reverse osmosis water,reducing the concentration of ammonia nitrogen in the reverse osmosis water.
