Abstract
The invention discloses an improvement method for realizing zero wastewater emission in calcium carbide production, and an apparatus thereof. An original water supply device in a circulating water pool is removed; a recovery tank is additionally installed, and wastewater in a fan and a pump are introduced into the recovery tank; and wastewater in the recovery tank is pumped into a calcium carbide furnace circulating water pool through the pump as supply water of the circulating water pool in order to realize the zero wastewater emission. The cooing water in the pump and the fan is recovered as calcium carbide reacting furnace cooling water supply water in the invention, so the water resource is maximally comprehensively utilized, energy saving and environmental protection are realized, and the calcium carbide production cost is also saved.
