Near-zero emission treatment system of circulating cooling water system

The utility model discloses a near-zero emission treatment system of a circulating cooling water system. The near-zero emission treatment system mainly comprises a physical descaling and scale prevention device, a water inlet main pipe, an electrolytic adsorption device, a membrane tank, a sewage discharge tank, a supernate drainage pump, a sludge sewage discharge pump, a compressor, a slag discharge pump, a dehydrator, a water storage tank, an acid adding pump, a chemical adding pump and a membrane water outlet pump. The utility model aims to provide a near-zero emission treatment system of a circulating cooling water system, which is used for solving the problem of external emission of circulating cooling water in the existing industries such as electric power, petroleum and chemical engineering, realizes near-zero emission of the system when the quality of circulating water reaches a balanced state, and simultaneously prevents heat exchange equipment such as a condenser from scaling or corrosion. 本实用新型公开了一
