| titleOfInvention | Treatment process of circulating cooling water with leaked ammonia nitrogen |
| abstract | The invention relates to a treatment method of circulating water with leaked ammonia nitrogen, which comprises the following steps: a) controlling the pH value of the circulating water to 7.5-9.0; b) adding a scale and corrosion inhibitor which comprises the following components: A) at least one phosphorus-free corrosion inhibitor, wherein the phosphorus-free corrosion inhibitor is selected from thiourea and its derivative and a nitrogen-containing heterocyclic compound type adsorption film corrosion inhibitor, B) at least one scale inhibiting dispersant which is at least one phosphorus-free polymer with a carboxylic group, and C) a zinc salt; c) adding at least one bromine-containing bactericide; and d ) adding at least one sulfonate nonionic surfactant. The invention controls the problems of corrosion, scaling, and bacterial growth in the circulating water system with leaked ammonia nitrogen by methods of adjusting the pH value of the circulating water, and combining with the phosphorus-free scale and corrosion inhibitor and the non-chlorine bactericide. |
