The invention discloses a high-safety conveying process of corrosive liquid. The method comprises the steps that a wave push pump is immersed in the corrosive liquid, a first transmission mechanism and a second transmission mechanism works, a main transmission roller rotates around the axis of itself, an auxiliary transmission roller rotates around the axis of itself, a synchronous rotating belt of the main transmission roller and the auxiliary transmission roller drives a transmission belt to move, the transmission belt moves to drive a wave push roller and an absorbing rod to move in the conveying direction of the transmission belt, a wave push shell laid on the transmission belt is in a wave shape, the wave push roller pushes the wave push shell to move, the contact position of the wavepush roller and the wave push shell is the crest, and a trough is arranged at the contact position of the absorbing rod and the wave push shell; the corrosive liquid enters a liquid inlet chamber through a filter plate of a liquid inlet chamber, and then flows to a communication pipe through the liquid inlet chamber, and the corrosive liquid can enter a closed cavity formed by the wave push shelland the side wall of a liquid inlet and outlet shell through a second water passing hole and is pushed to a third water passing hole under the pushing effect of the wave push shell to be discharged.
