【摘要】：近年來，許多大規(guī)模的海水淡化工程陸續(xù)建成投產(chǎn)，其廢棄的大量高濃度海水往往最終排入大海，不僅造成了有限資源的浪費，還會對海洋生態(tài)環(huán)境有一定影響。因此，，對海水淡化副產(chǎn)的濃海水進行化學資源的綜合利用是十分必要的。滄電是我國較早使用海水淡化發(fā)電的大型發(fā)電企業(yè)，本文以其濃海水綜合利用項目為研究對象，試圖對該類新興項目產(chǎn)品的市場需求、項目的經(jīng)濟性和社會效益進行全面研究，為該類項目投資決策提供理論方法和實際依據(jù)。 本文通過對國內(nèi)外相關工程項目技術分析以及經(jīng)濟和社會效益評價文獻資料進行分析研究，結合國華滄電濃海水綜合利用項目的特點，在對該項目產(chǎn)品氯化鉀、溴素、液體鹽、海水鎂砂（氧化鎂）四種產(chǎn)品的市場需求與競爭力進行分析的基礎上，從工藝技術、生產(chǎn)設備等方面對項目工程建設方案的技術性進行了詳細分析；隨后對濃海水提取氯化鉀、溴素、液態(tài)鹽和海水鎂砂四個子項目進行了財務評價和抗風險能力分析，得出了暫緩濃海水提取液態(tài)鹽和海水鎂砂的項目，選取濃海水提取氯化鉀和溴素兩個子項目進行組合投資的方案，并對組合投資項目進行了財務評價和抗風險能力分析，結果表明該投資組合可以取得良好的經(jīng)濟效果。最后，建立了項目社會影響評價指標體系，采用基于層次分析法的模糊綜合評價方法對該項目的社會效益進行了評價。 通過對濃海水綜合利用項目從技術、經(jīng)濟和社會三個角度進行技術經(jīng)濟評價研究，得出以濃海水為原料提取氯化鉀、溴素的項目無論從技術的先進性和可行性、項目的經(jīng)濟性，還是從項目的社會效益來看，都具有很強的可實施性。為項目投資者做出正確的投資決策提供科學地依據(jù)。
[Abstract]:In recent years, many large-scale desalination projects have been completed and put into operation one after another. A large amount of abandoned high-concentration seawater is often discharged into the sea, which not only results in the waste of limited resources, but also has a certain impact on the marine ecological environment. Therefore, it is necessary to make comprehensive use of the chemical resources of by-product concentrated seawater from desalination. Cang Power is a large-scale power generation enterprise which used seawater desalination earlier in our country. This paper takes its concentrated seawater comprehensive utilization project as the research object, and tries to make a comprehensive study on the market demand, the economic and social benefits of this kind of emerging project products, and the economic and social benefits of the project. It provides the theoretical method and practical basis for the investment decision of this kind of project. Based on the technical analysis and economic and social benefit evaluation of relevant engineering projects at home and abroad, combined with the characteristics of Guohuacang Electric concentrated seawater Comprehensive Utilization Project, this paper is concerned with the production of potassium chloride, bromine, liquid salt, and so on. Based on the analysis of the market demand and competitiveness of the four kinds of products, the technology of the project construction scheme is analyzed in detail from the aspects of process technology, production equipment and so on. Then, four sub-projects of extracting potassium chloride, bromine, liquid salt and seawater magnesite from concentrated sea water were evaluated financially and the risk-resisting ability was analyzed, and the project of suspending the extraction of liquid salt and seawater magnesite from concentrated sea water was obtained. Two sub-projects of extracting potassium chloride and bromine from concentrated seawater are selected for portfolio investment. The financial evaluation and risk resistance analysis of portfolio investment projects are carried out. The results show that the portfolio can achieve good economic results. Finally, the social impact evaluation index system of the project is established, and the social benefit of the project is evaluated by the fuzzy comprehensive evaluation method based on the analytic hierarchy process (AHP). Through the technical, economic and social evaluation of the project of comprehensive utilization of concentrated sea water, it is concluded that the project of extracting potassium chloride with concentrated sea water as raw material, the project of bromine no matter from the advanced nature and feasibility of technology, and the economy of the project, Or from the social benefits of the project, both have a strong enforceability. To provide a scientific basis for project investors to make correct investment decisions.
