description The invention belongs to the technical field of industrial circulating cooling water scale and corrosion inhibition treatment, and relates to a phosphorus-free circulating water composite scale and corrosion inhibitor and a preparation method and application thereof, the phosphorus-free circulating water composite scale and corrosion inhibitor comprises the following components by mass: 26-33% of disodium cocoamphodipropionate, 8-10% of sodium tartrate, 1-2% of sodium thioglycolate, 0.1-0.2% of concentrated hydrochloric acid, and 54.8-64.9% of deionized water. The composite scale and corrosion inhibitor provided by the invention not only has efficient scale inhibition performance, but also has excellent corrosion inhibition performance in various circulating cooling water systems, and has broad-spectrum stability, and key components of the composite scale and corrosion inhibitor are efficient and environment-friendly, so that the composite scale and corrosion inhibitor is particularly suitable for being appli
