The invention discloses an energy-saving recycling combination system for industrial circulating cooling water. The system comprises two circulating cooling water systems, namely, a sealed-type circulating cooling water system and an open-type circulating cooling water system and specifically comprises a cold water tank, a water treatment process device, a cooling water supply pump, a pressure sensor, a flow sensor, a cooled device, an intermediate water tank, a lift pump, a cooling tower, a heat pump set, a hot water tank, a liquid-level sensor and an electronically controlled device and is an energy-saving and water-saving optimized combination system for industrial circulating cooling water. Serial-type water supply is adopted in the sealed-type circulating cooling water system, parallel-type water supply is adopted in the open-type circulating cooling water system, the utilization rate of the cooling water is increased to a maximize extent and the water supply amount of the cooling water is decreased. Since the system is provided with the water treatment process device, the water quality of the circulating water is improved, the sewage discharge capacity is decreased and the concentration multiple of the circulating water is increased. By arranging the heat pump set in the system, the low-temperature waste heat of the return water of the cooling water is effectively recovered, the evaporation amount is reduced and the effective utilization of the heat source is achieved and the system has important practical values.
