| 摘 要： | 用浙江缙云的天然斜发沸石在实验室进行了吸附铵饱和沸石的生物再生静态试验，经过73d生物作用和离子交换作用，饱和沸石对铵的吸附能力恢复了61%～85％；在云南滇池流域进行了吸附大量铵的沸石的生物再生现场中试试验，经过4～6个月的自然生物再生过程，沸石对铵的吸附能力恢复了22%～36％。

| Abstract: | Using the natural clinoptilolite from Jinyun County, Zhejiang Province as the experimental samples, a static bio-regeneration experiment was conducted for the zeolite saturated with ammonium. The ammonium adsorption capacity of the saturated zeolite were recovered 61%～85% after 73 days by biological process and ion exchange. An on-site pilot experiment of bio-regeneration was also conducted for the zeolite absorted large amount ammonium in Dianchi Lake basin, Yunnan Province. The ammonium adsorption capacity of the zeolite were recovered 22%～36% after 4～6 months by natural biological process. |
