Experimental Research on Wastewater Reuse Technology of Industrial Circulating Cooling Water System

摘要

By means of decrease of hardness, neutralization and desalination union technology, the drained wastewater of industrial circulating cooling water system can be treated. The purified water quality (total hardness and calcium ion components) is greatly better than fresh water, and completely can be reused as make-up water for circulating cooling water system. The experimental results show that the ratio of wastewater reuse reached more than eighty percent, saving a large amount of fresh water, reduce waste water discharge, water saving and emissions reduction effect is obvious, and the production cost greatly reduced.
