- Abstract
This thesis presents a new method of processing copper_bearing wastewater. The humic acid type water purifier, in form of particles, is manufactured from weathered coal of Nantong Mining Area in Chongqing. Through static test, the optimum condition on treating copper-bearing waste water has been found out. Then the washing water for copper plating, which contains Cu2+ 124 mg.L-1, is treated by dynamic test. When the concentration of Cu2+ in the outlet water is lower than the national standard for draining (1.0 mg.L-1), the working capacity of absorption is 32.4 mg.L-1 and the saturation capacity of absorption is 45.8 mg.L-1.
