与蒸馏法相比,反渗透淡化无需热源,且耗电量因比蒸馏法少,因此它是一种经济性很好的低能耗淡化方法。 本课题主要是对反渗透膜组件造型,预处理系统高压设备和装置系统设计进行了研究,解决了原水的预处理,研制出了高压调节阀、高压泵及装置样机。该装置采用膜分离这一新技术,具有节能、紧凑、操作简便等优点,所采用的砂滤和超滤二级预处理流程既能满足反渗透膜组件的进水要求,又能保证系统长期可靠运 Compared with the distillation method, reverse osmosis desalination without heat source, and power consumption than distillation less, so it is a very economical low-energy desalination method. This topic mainly researches the design of the reverse osmosis membrane module and the pretreatment system high pressure equipment and device system, solves the pretreatment of the raw water and develops the high pressure regulating valve, high pressure pump and device prototype. The device uses the membrane separation of this new technology, with energy saving, compact, easy to operate and so on, the use of sand filtration and ultrafiltration two pre-treatment process to meet both reverse osmosis membrane components of the water requirements, but also to ensure long-term system Reliable transportation
