| 摘 要： | 采用自制的ＴＣ型钛系催化剂（ＴｉＯ２／ＣｏＯ），对于含汞为５０ｍｇ／Ｌ的试液，经一次性处理，并控制试液ｐＨ＝７．５，搅拌２ｍｉｎ，可使试液中汞含量降至０．０００４４ｍｇ／Ｌ，汞去除率达９９．９９％以上。催化剂可重复使用，并可用ＨＣｌ溶液再生。方法简便、快速。对于５种工厂废水试验结果令人满意。

| Abstract: | A new process for efficiently removing soluble mercury from wastewater has been developed by using a TiO2/CoO (TC) catalyst developed by the authors. The TC catalyst was stirred with wastewater to be treated at PH7. 5 for 2 min, allowing the concentration of mercury in wastewater to be reduced from initial 50 mg/L to final 0. 00044 mg/L. The TC catalyst can be repeatedly used, and can be regenerated by HCI if its activity has been reduced to a certain extent. This process has been applied to the treatment of five different wastewaters containing soluble mercury from factories, giving satisfactory results. |
