摘要
水资源作为基础性和战略性的资源,对社会的可持续发展具有重要意义,国家对工业用水控制较为严格,所以,火力发电厂作为用水大户,对电厂内各级废水的综合利用显得尤为重要。本文针对火力发电厂的废水梯级利用做一个较为全面的技术经济比较,寻求减少取用新鲜水的途径,同时降低废水排放量;既减少了水资源的消耗,又减少了废水对环境的污染,对建设生态型环境可提供较大的贡献。
As a basic and strategic resource,water resources are of great significance to the sustainable development of society.The state controls the use of industrial water more strictly.Therefore,as a major water user,the comprehensive utilization of waste water at all levels in power plants appears.This article aims to make a more comprehensive technical and economical comparison of waste water cascade utilization in thermal power plant and seek to reduce the access to fresh water and reduce the discharge of waste water.It not only reduces the consumption of water resources but also reduces the waste water to the environment Of the pollution,to the ecological environment can provide a greater contribution.
