Chips are the most core and important component of the information industry, and the soul of China's intelligent manufacturing. In semiconductor chip manufacturing technology, semiconductor chips with various functions are formed through a series of processes such as photolithography, etching, deposition, ion implantation, grinding, cleaning, etc., which will generate a large amount of wastewater. The types of pollutants in wastewater include fluoride, acid-base waste liquid, organic waste liquid, heavy metal ion pollutants, etc., which are highly corrosive and toxic.
After in-depth analysis of the production process, our company divides the wastewater into multiple types, including fluorine-containing wastewater, ammonia containing wastewater, CMP grinding wastewater, heavy metal wastewater, etc. Based on the different water quality of each type of wastewater, separate treatment processes are designed. By implementing effective pre-treatment measures, various types of wastewater can be treated to meet standards and recycled for resource utilization.
