Effects of calcium ions in circulating cooling water on enzyme activities,characteristic performance and corrosion inhibition performance of lysozyme and lipase were studied.The composition of bio-enzyme corro-sion inhibitor using calcium ions in circulating cooling water as additive was optimized by orthogonal experi-ment.Results showed that,calcium ions in circulating cooling water could elevate activities of bio-enzyme and enhance the corrosion inhibition performance.When the mass concentration of lysozyme was 20 mg· L-1 ,the mass concentration of lipase was 70 mg·L-1 and the mass concentration of calcium ions was 157.57 mg·L-1, the most ideal corrosion inhibition effect achieved,with the corrosion rate of the carbon steel hangers of 0.0007 mm·a-1 and the corrosion inhibition efficiency of 99.79%.
