Abstract:

Water treatment chemicals have the function to inhibit the scale formation in industrial circulating water.However, only relying on water treatment chemicals can not obtain the expected result when the water has high hardness, high alkalinity or high SO₄^2- . Based on this situation, adjusting the pH will improve the inhibitive effect. Aiming at the water quality situation at Linhuan Power Plant, a series of experiments have been done, exploring the effect of pH on the inhibition capacity of water treatment chemicals.

Key words: water treatment chemicals, high hardness, pH adjustment

摘要：

水处理药剂可抑制工业循环水系统结垢, 但是对于一些高硬度、高碱度、高硫酸根的水质, 仅仅依靠水处理药剂往往达不到预期的效果。可以通过调节pH改善阻垢效果。作者针对临涣电厂水质进行了一系列的试验, 探究了pH对水处理药剂阻垢能力的帮助。
