| 中文摘要 |
| 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。 |
| 英文摘要 |
| 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. |
