摘要
针对城市污水处理厂二级出水回用作循环冷却水补充水的工艺,采用新型杀生剂与阻垢剂组合进行了动态试验。加入药剂后腐蚀速率为0.00087g/(m2.h)和0.00116g/(m2.h),缓蚀率在80%左右,表明该药剂能较好地控制铜管腐蚀。
The industrial experiment by a combination of new biocide and scale inhibitor in recycle cooling system using city wastewater as makeup water was introduced. When the biocide and scale inhibitor were joined,the corrosion rate was 0. 000 87 g/（ m^2 · h ） and 0.001 16 g/（ m^2· h ）, the slow eclipse rate was about 80%. The results indicated that new biocide and scale inhibitor can inhibit the corrosion of copper pipe in city sewage.
