SYSTEM FOR PRODUCING HYDROGEN ENERGY USING THE SILLICON WASTE WATER AND METHOD FOR PRODUCING HYDROGEN ENERGY USING THE SILLICON WASTE WATER

摘要

PURPOSE: A system and a method for generating hydrogen energy using silicon wasted water are provided to improve the collecting ratio of reusable processing water based on the silicon wasted water by secondarily processing the processing water. CONSTITUTION: An immersing type ultra filtration processing bath(200) implements an ultra filtration process with respect to silicon wasted water, which is generated from an ingot processing process, and separates the silicon wasted water into an ultra filtration processing water and silicon concentrated wasted liquid. A line mixer(400) is in connection with the immersing type ultra filtration processing bath and receives the silicon concentrated wasted liquid and alkaline chemical. The silicon concentrated wasted liquid and the alkaline chemical are mixed. A hydrogen gas generating bath is in connection with the line mixer and generates hydrogen gas and strong alkaline water and neutralizes the strong alkaline water to be separated into supernatant and precipitates.
