垃圾渗沥液中膜系统优化设计

摘要

纳滤膜和反渗透膜在垃圾渗沥液处理过程中,易出现膜污染严重、清洗频繁、使用寿命短等问题.阐述了渗沥液膜系统设计的经验参数和注意事项,在膜系统设计方面作出了改进,优化了传统的膜清洗方法,以减轻渗沥液膜系统污染,使其长期稳定运行.%Some problems usually appeared in the process of using NF membrane and RO membrane to treat leachate,such as membrane pollution,frequent cleaning,short lifespan and so on.Leachate membrane system was introduced in this paper,including the experience of the design parameters and some attention items.Improvement in membrane system design was raised.Optimization of the traditional membrane cleaning method was put forward,in order to reduce membrane pollution and make its long-term stable operation.
