description The invention provides a novel scale and corrosion inhibitor for circular cooling water treatment. The inhibitor is characterized by being a composite of chemical materials which are nontoxic, phosphorus-free, pollution-free and low in price. The inhibitor belongs to the phosphorus-free formula; no scale of calcium phosphate is formed in use; the sewage generated by using the formula causes no eutrophication pollution to the environment; and thus the inhibitor is an environment friendly product. The scale and corrosion inhibitor in the invention possesses good general properties, excellent CaCO3 and Ca3(PO4)2 scale inhibiting ability, and good capability to stabilize Zn2+ in water and corrosion inhibiting ability. The scale and corrosion inhibitor can increase the concentrate multiplying factor of the circulating cooling water and be used when the sum of calcium hardness and total alkalinity is up to 1200 mg/L after circulating water is condensed. The inhibitor can substitute present scale and corrosion inhib
