摘要
火电厂是工业用水大户,其大量抽取地下水或江河湖泊等地表水的代价非常大,另一方面,电厂又有大量工业废水(主要是循环排污水)外排,既污染了环境,又浪费了资源,循环排污水回用具有很好的环境效益、社会效益和经济效益。本文结合京丰燃气发电厂和三河电厂二期循环排污水回用处理试验,重点研究了循环排污水回用处理中采用混凝工艺时参数的选择,以及循环水中阻垢缓蚀剂对混凝过程的影响。
Thermal power plants are large consumers of industrial water, they are paying high cost while extracting large amount of underground water and surface water from rivers and lakes, but on the other hand ,the power plants also produce large amount of waste water, mainly circulating sewage ,which not only bring about pol]ution, but also waste resources. The recovery use of circulating waste water is good for environment ,and has social and economical benefits. This paper mainly studied data selection of coagulation technique and influence of scale-corrosion inhibitor in circulating waste water on coagulation process in the light of circulating waste water treatment test in Jingfeng Gas Turbine Power Generation Co. Ltd. and Sanhe Power Plant Phase Ⅱ .
