摘要
针对现阶段练江流域污染水体氨氮高、COD含量低的特点,采用浮萍进行生态修复,经过21天的生态修复,氨氮、TN、TP浓度都能达到《地表水环境质量标准》(GB3838-2002)Ⅲ类标准以上,还使得水体溶解氧含量得到升高。另外用浮萍进行练江流域的生态修复,达到6天后就可以采收,如果还需进一步降低TN可以进行第二批的浮萍修复。
Aiming at the characteristics of high ammonia nitrogen and low COD content in the polluted water body of Lianjiang River Basin at present,duckweed was used for ecological restoration.After 21 days of ecological restoration,the concentrations of ammonia nitrogen,TN and TP can reach the class Ⅲ standard of environmental quality standard for surface water(GB3838-2002),and the dissolved oxygen content of water body was also increased.In addition,duckweed can be harvested after 6 days of ecological restoration in Lianjiang River Basin.If TN needs to be further reduced,the second batch of duckweed can be restored.
