Abstract: The seriousness of heavy metal thallium pollution is indicated. And the current situation of the technologies for treating wastewater containing thallium,in China are introduced. By means of field survey on several lead and zinc smelting enterprises,the running costs,principles and the standard reaching situation of the treatment technologies in lead and zinc smelting enterprises are analyzed and compared. The investigation results show that the costs of chemical agents and energy consumption in every enterprise are controlled at ￥ 2.5-7.5 per ton,and the mass concentration of wastewater discharge can be controlled at 0.005 mg/L. Every enterprise should choose appropriate, economical and environment-friendly types of technologies,according to the characteristics of thallium-containing wastewater,so as to gain optimal treatment results.

Key words: thallium, lead and zinc enterprises, industrial wastewater, heavy metal
