Abstract

The invention discloses an environment-friendly organic silver composite recirculating water treating agent and an application thereof. The water treating agent is a liquid aqueous solution composition containing histidine silver complex and polycarboxylic acid antisludging agent. The application method of the water treating agent is to add the water treating agent into industrial water with a certain volume. Compared with the prior art, the environment-friendly histidine silver complex and the polycarboxylic acid antisludging agent are taken as effective components of the recirculating water treating agent, so that the water treating agent is not discolored or settled, and can keep long-term corrosion inhibition and sterilizing effect, without being added with other antisludging agent, corrosion inhibition, sterilizer or algicide. The water treating agent is environment-friendly and energy-saving, and is a substitution for phosphorus-based water treating agent and the best option for the company to implement energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a composite circulating water treatment agent and its application, in particular to an environment-friendly organic silver composite circulating water treatment agent and its application. Background technique [0002] Scale, dirt, corrosion, bacteria and algae, pipe network corrosion and concentration multiple control problems commonly exist in industrial cooling circulating water systems. Generally, chemical agents such as corrosion and scale inhibitors and bactericides are added, which are so-called circulating water treatment agents. The current industrial circulating water treatment agents mostly use phosphorus-based descaling agents containing organic phosphonic acid, but organic phosphonic acid contains high phosphorus, which will lead to eutrophication of waters, promote algae growth, and phosphorus scale, red tide and other phenomena; in addition , Fungicides are mostly used isothiazolines, chlorine preparations, quater...
