中水回用于火电厂循环水系统的影响与工艺探讨

Discussion on the influence and technology of reclaimed water reuse in circulating water system of thermal power plant

城市中水回用于火力发电厂循环水系统成为火电行业节水的重要措施之一。但中水水质复杂,直接回用于循环水系统会引发腐蚀、结垢和微生物污染等问题。在分析中水关键水质指标对循环水系统影响的基础上,提出指标控制建议和原则,分析部分中水深度处理工艺。

The recycling of urban reclaimed water to the circulating water system of thermal power plants has become one of the important measures for water saving in thermal power industry. However, due to the complex quality of reclaimed water, reuse in the circulating water system will cause many problems such as corrosion, scaling and microbial contamination. Based on the analysis of the influence of key water quality indicators of reclaimed water on the circulating water system, the paper puts forward suggestions and principles for index control, and analyzes some advanced treatment processes of reclaimed water.
