The invention discloses an anti-freezing system and method based on water tower operation parameter feedforward control. The anti-freezing system comprises a DCS control system and a PID controller. A plurality of water tower anti-freezing baffle systems are arranged at an air inlet of the water tower, a circulating water inlet temperature measuring point is arranged at a water inlet of the water tower, and a circulating water return temperature measuring point is arranged at a water outlet of the water tower. A first anti-freezing area monitoring temperature measuring point and a second anti-freezing area monitoring temperature measuring point are arranged in the area where an anti-freezing baffle in the water tower anti-freezing baffle system is located. The DCS control system is connected with a first anti-freezing area monitoring temperature measuring point, a second anti-freezing area monitoring temperature measuring point, a circulating water inlet temperature measuring point and a circulating water ret
