Abstract: Due to frequent leakage and aging of the equipment, the quality of circulating water in a refinery circulating water plant of a petrochemical enterprise deteriorates. In order to avoid serious impacts on the heat exchanger of the production unit, the treatment scheme of circulating water is optimized and improved. The turbidity of the circulating water system is reduced to below 20 NTU and the total phosphorus is controlled in the range of 7-9 mg / L through implementing new dosing scheme and reasonable control of sewage discharge. The quality of the circulating water is improved effectively and the operation and management level of the circulating water system is strengthened.

Key words: circulating water, leakage, medicament, turbidity, total phosphorus
