我国再生汞企业含汞废水产生量及单位产品废水中汞的产生及排放量变化幅度较大，企业对含汞废水的处理工艺多为化学沉淀法，工艺较为简单，导致车间排放口不能达到《污水综合排放标准》。针对再生汞企业存在的问题，介绍了铁屑还原法、硫氢化钠-明矾法、活性炭吸附法和离子交换法，以及采用不同工艺的组合流程处理含汞废水的方法，提出了再生汞企业含汞废水治理的进一步改进的措施建议。

The mercury-containing wastewater output and the change range of the production and discharge of the mercury in the wastewater of unit product of Chinese regenerated mercury enterprises are great, and enterprises' treatment process of the mercury-containing wastewater is generally the chemical precipitation method, which is rather simple and results in that the discharge outlet in the workshop fails to meet the Integrated Wastewater Discharge Standard. Due to the existing problems on the regenerated mercury enterprises, this thesis introduces the scrap iron reduction method, sodium hydrosulfide - alum method, active carbon adsorption method, ion exchange method, and mercury-containing wastewater treatment methods through the combined process of different technologies, and proposes the suggestions on the further improvement measures for the mercury-containing wastewater treatment for regenerated mercury enterprises.
