| With the rapid development of modern industry,the demand of fresh water has increased dramatically.At present,many countries in the world are obviously required the shortage of fresh water,industrial and agricultural production in many areas is even difficult to find up to the standard of drinking water.So,the problem of fresh water supplies has become a question which people must be considered.In terms of per capita,China is a poor country in terms of water resources.According to estimates,China’s per capita water ranks 88 th in the world.Our country has a long coastline,islands and coastal saline area and inland area of brackish water are lack of fresh water areas,which directly affect the health of the residents in the local and economic construction.Therefore,the fresh water supply is to our country face a serious problem.In order to increase the supply of fresh water,in addition to the conventional water diversion or nearby inter-basin water transfer,another way is to nearby sea water or brackish water desalination.This paper takes shouguang region as the research object,aiming at the problem of being short of fresh water resources study,a detailed analysis of the current commonly used desalination processing technology.Electro dialysis technology,reverse osmosis technology,distillation desalination technology.Combination with the determination of the water quality of sand silted chose appropriate technology-reverse osmosis desalination technology,and the process of project construction in detail the design of the study,the location of the project selected standard,fine project method,the required equipment selection have made detailed calculation,specifications are studied,Make a preliminary budget and the economic benefit,finally the feasibility of the project for all aspects of the analysis,Including market analysis,policy support,project resources comprehensive utilization and energy saving analysis,the project has a good prospects for development. |
