中文摘要	As the advanced technology to make freshwater, seawater desalination plays more and more important roles in solving the scarcity of freshwater resource in coastal areas and offshore areas. Especially in the remote sea area such as the remote islands, oil drilling platform in the sea and big warships, high energy consumption and large investment limit the application of medium and small type seawater desalination device. So it is necessary to develop a new type high-efficiency and energy-saving seawater desalination device to boost the ocean development. First of all, the main seawater desalination methods, the development and actuality of seawater desalination in and abroad and the main study aspect of seawater reverse osmosis (SWRO) desalination today are introduced in the first chapter of this thesis. The second chapter is mainly about the basic theory and elementary knowledge of reverse osmosis (RO). Then the 10t/d SWRO device is designed in the third chapter. The design is made up of three parts: pretreatment system, RO system and energy recovery system. We do a series of experiment study and analysis to the SWRO device in the fourth chapter, and get a lot of results and many running rules. In the fifth chapter, we set up the mathematic model of energy recovery device (ERD) and efficiency model, study and evaluate the performance of the ERD. The 10t/d SWRO device is a high-efficiency and energy-saving desalination device relative to other medium and small type SWRO devices, and it is lower investment. The 10t/d SWRO device uses newly-designed differential type ERD, so the pressure and freshwater output fluctuations coming from on-off of the electric valve are eliminated almost. And we needn’t use boosting pump after ERD as the other positive-displacement ERD, so it can simplify the process flow. The total energy consumption for per ton freshwater of the 10t/d SWRO device is about 5 kWh/m3.Thereinto gross high pressure energy consumption (considering the dissipation of the electric motor and high-pressure pump) is 3.6 kWh/m3, and the high pressure energy consumption (not considering the dissipation of the electric motor and high-pressure pump) is only about 2.4 kWh/m3. Keyword: seawater desalination; reverse osmosis (RO); high-efficiency and energy saving; energy recovery device (ERD).
