| Abstract: |
| As a member of China Cleaner Nonferrous Metals Production Investigation Group to Canada, author investigated two techniques for wastewater treatment, CANSOLV low-SO_2 purification and HDS process, for Noranda Zinc Smelter, INCO's Nickel Smelter and Copper Refining Plant in Canada. The experience from the investigation is that cleaner production technology has the characteristics of energy saving, less consumption and low pollution, reflected in the advanced smelting process, equipment and management; the so-called cleaner technology is relative and steadily improved along with social progress; to put the cleaner technology into practice is a cardinal way to eliminate industrial environment pollution in China. For this reason, the advanced cleaner production technologies should be introduced so as to speed up the expansion of cleaner production technology in China. |
