超高压卷式反渗透在垃圾渗滤液膜浓缩液减量化中的应用研究

Research on application of ultra-high pressure roll-type reverse osmosis in reduction of landfill leachate membrane concentrate

当前,生活垃圾渗滤液膜浓缩液主要采用碟管式反渗透(DTRO)膜进行减量化处理,但该技术存在投资成本高,运行过程易渗漏、检修繁琐等一系列问题.为解决该难题,本研究创新性地设计了一套超高压卷式反渗透成套设备用于渗滤液膜浓缩液的处理,为替代DTRO和STRO进行垃圾渗滤液膜浓缩液减量化处理提供了新的选择.同时对该套设备进行箱式集成处理,其简便、快捷的设计模式为后期工艺的调整提供了更多可能性.

At present,the concentrated liquid of household garbage filtration membrane mainly uses dish and tube reverse osmosis(DTRO)membrane for reduction treatment,but this technology has a series of problems such as high investment cost,easy leakage in operation process and tedious maintenance.In order to solve this problem,a complete set of ultra-high pressure roll-type reverse osmosis equipment for the treatment of leachate membrane concentrate was creatively designed,which provides a new choice to replace the reduction treatment of landfill leachate membrane concentrate treated by DTRO and STRO.At the same time,through the box integrated processing of the set of equipment,the simple and fast design mode provides more possibilities for the later process adjustment.
