中国正面临着水资源短缺与水资源污染两大问题,人均淡水资源只占全世界平均水平的1/4,是人均水资源最少的国家之一,日益严重的水污染问题不仅降低了水体的质量,而且还进一步威胁到我国居民的饮水安全和健康。
工业用水是造成这两个问题的主要因素,另一方面,水资源短缺又限制了能源行业的发展,两者之间存在着矛盾,而在各类能源中,电力生产消耗的水量远超过石油煤炭等其他能源行业,火电厂成为主要用水单元,占所有能源行业的80%以上。在电力的生产过程中,水电不消耗水资源;核电用水量很少;仅仅是火电大量的使用或消耗水资源。火力发电作为我国的主要发电方式,占到全国发电量80%,而火电用水则占到工业用水的1/6,为了能营造一个节水型社会,缓解水资源紧张问题,火电行业做好节水减污势在必行。
本文主要讲述了火电厂节水的必要性和节水的各类措施,包括管理上、技术上和设备上的改进,讲述了水平衡测试的方法和对于电厂节水的潜力和好处,此外,对电厂部分用水系统,包括除盐水系统,脱硫用水系统的改进进行阐述,针对大型空冷机组的节水能力和如何实现废水的零排放问题进行了具体分析。

China is faced with the shortage of water resource and pollution of water resources two big questions, fresh water of average per capita resources only occupies the 1/4 of world average level, average per capita water least natural resources is one of the countries, the increasingly serious water pollution problem not only reduced the water quality, but also further threats to our country residents' drinking water safety and health.
Industrial water is caused by this two problem was the main factor, on the other hand, the shortage of water resources and limit the energy industry, there exists the contradiction between the two, but in all kinds of energy, electric power consumption of production capacity more than oil and coal and other energy industry, thermal power plants have become the main water unit, accounted for all of the energy industry more than 80%.In the electricity production process, no consumption of water resources hydropower; nuclear power with little water; only power use or consumption of water resources.Thermal power generation in China as the main power, occupy countrywide electricenergy production 80%, while power water to occupy the 1/6 of industrial water, in order to create a water-saving society, alleviate the shortage of water resources, saving water and reducing pollution of thermal power industry to be imperative.
The paper is mainly about the water saving in power plant and the necessity of water-saving measures, including management, technology and equipment improvement, tells the story of water balance test method and for power plant water potential and benefits, in addition, on the part of power plant water supply system, including the desalted water system, water system improvement of desulfurization, for large air cooling unit water capacity and how to realize zero emission of waste water problems are analyzed.(可以吗,望采纳)

Industrial water is caused to the two problem was the main factor, on the other hand, the shortage of water resources and limit the energy insdustry, there exists a contradiction between the two, but in all kinds of energy, electric power consumption of production capacity more than oil and coal and other energy industry, become the main water in thermal power plant unit, accounted for all of the energy industry more than 80%. In the electricity production process, not consumption of water resources hydropower; nuclear powers with little water; only power use or consumption of water resources. Thermal power generation in China as the main power, accounting for the national generating capacity 80%, and the power of water to occupy the1 /6of industrial water, in order to create a water-saving society, alleviate the water resources shortage, water saving and reducing pollution in thermal power industry to be imperative.
