Abstract

The invention relates to a green water treatment agent with corrosion-inhibition and scale-inhibition performances and an application thereof, belonging to the field of treatment of water pollution. In order to overcome the technical problems of high production cost and poor application scope of a water treatment agent in the prior art, the compounded water treatment agent provided by the invention is composed of 0.5 to 1.5 parts of polyaspartic acid, 30 to 50 parts of sodium molybdate, 25 to 55 parts of triethanolamine, 10 to 16 parts of lignin sulfonate, 2 to 4 parts of sodium tripolyphosphate, 5 to 7 parts of mercaptobenzothiazole, 4 to 10 parts of polydimethyldiallylammonium chloride, 0.6 to 1.2 parts of cerium acetate, 3 to 9 parts of 1-phenyl-5-mercapto-tetrazole, 2.5 to 4.5 parts of 5-[3-phenyl-4-(2'-thiophene methine)imino-(1,2,4)s-triazole)thio-N-(2'-thiophene)methine acethydrazide and water. The green water treatment agent provided by the invention has the advantages of reasonable formula, excellent corrosion-inhibition and scale-inhibition performances after compounding, simple preparation method, low cost, and good application and popularization values compared with a conventional water treatment agent.

Description

technical field [0001] The invention relates to a green water treatment agent with corrosion and scale inhibition performance and application thereof, belonging to the field of water pollution treatment. Background technique [0002] Due to the massive consumption of global water resources by industrial development and the continuous deterioration of the global water environment, my country invests a lot of money in water pollution control every year. In order to meet the requirements of sustainable development, it has become a top priority to develop water treatment agents with superior performance, low price and no pollution to the environment. The green water treatment agent with excellent corrosion and scale inhibition performance can not only effectively inhibit the scaling and corrosion of circulating cooling water, save the consumption of circulating cooling water but also prolong the service life of equipment. [0003] The green water treatment agent with corrosion ...
