摘要：

对邯钢污水厂出水回用于循环水系统的过程中由于氨氮偏高导致碱度降低而引起系统腐蚀加重的现象进行了分析,同时提出了对循环水系统的治理措施及治理过程中存在的问题。

关键词: 污水回用, 循环水, 氨氮, 碱度降低

Abstract:

In the course of wastewater reusing in the circulating water system at the Wastewater Treatment Plant of Handan Iron and Steel Co., the corrosion problem in the system became more serious has been analyzed. It is found that the high ammonia-nitrogen resulted in the alkalinity reduction. The treatment measures and problems existed during the treatment in circulated water systems are put forward.

Key words: wastewater reuse, circulating water, ammonia-nitrogen, alkalinity reduction
