含汞废水复合硫化法处理工艺

介绍了工业含汞废水常用的除汞方法———活性炭吸附法、化学沉淀法、离子交换法、还原法、微生物法,阐述了北京中科国益环保工程有限公司研发的复合硫化法(引入复合助剂IAMD-08)处理含汞废水的原理及工艺流程,列举了该工艺在化工企业的实际运行数据,含汞废水经处理后汞的质量浓度小于0.005 mg/L。

Composite sulfidation process for treatment of waste water containing mercury

Commonly used processes for the treatment of industrial waste water containing mercury, such as active carbon adsorption method,chemical precipitation method,ion exchange method,reduc- tion method and microorganism method were introduced. The principle and flow of composite sulfidation process（ introducing complex additive IAM D-08） developed by Beijing China Sciences Environment Protection C o.,Ltd. for the treatment of waste w ater containing mercury were discussed. The actual operation data of this process in chemical enterprises were listed,show ing that the mercury content in the treated waste water was less than 0. 005 mg / L.
