| 摘 要： | 针对养猪废水中有机污染物和氨氮(NH4+-N)浓度高、悬浮物含量高的特点,采用循环流人工湿地工艺对其进行处理,研究以天然钙型沸石为基质的人工湿地对模拟养猪废水的处理效能。结果表明:历时22个月的高NH4+-N负荷运行,已使人工湿地中的钙型沸石对NH4+-N的吸附达到饱和。在天然钙型沸石填料铵饱和条件下,湿地系统对模拟养猪废水中NH4+-N的处理效果仍可达61%~76%,对TN的去除率可达66%~80%,对CODCr的去除率一直维持在78%~92%之间。

| Abstract: | Swine wastewater contains high concentrations of organic contaminants, ammonium nitrogen（NH＋4-N） and suspended solids.The circular flow constructed wetland（CFCW） stuffed with natural Ca-form zeolite was employed to treat swine wastewater and its treatment efficiency was studied.The results showed that natural Ca-form zeolite in CFCW had been saturated with NH＋4-N due to adsorption after 22 months performance with high NH＋4-N load,and under such condition,the elimination rates of the wetland system for NH＋4-N,TN,and CODCr removals still kept at 61%～76%,66%～80%,and 78%～92%,respectively. |
