凤眼莲-固定化氮循环细菌联合作用对富营养化水体原位修复的研究
In situ remediation of eutrophic water bodies by the combination of water hyacinth and immobilized nitrogen cycle bacteria
摘要
Abstract
The combination of water hyacinth (WH) and immobilized nitrogen cycling bacteria (INCB)was used in the remediation of eutrophic water bodies in situ with the ecological engineering technology in the summer. The results showed that there were significant differences between WH and WH + INCB for total nitro-gen (TN) and ammonia nitrogen (NH_4-N) of eutrophic water bodies. TN and NH_4-N removal rates in eutrophic water bodies with WH + INCB reached 77.2% and 49. 2%,respectively,while 73.7% and 32.3% for WH,respectively. In addition,there was no significant difference between WH and WH + INCB for nitrate removal.Chla and COD_(Mn) decreased and transparency increased in eutrophic water bodies in WH + INCB treatment,but there was no significant difference between WH and WH + INCB treatments. Compared with WH treatment sys-tem,the populations of nitrosation,nitrifying,and denitrifying bacteria increased by 1 to 1.5 orders of magni-tude in WH + INCB treatment systems. However,the ammonifying bacteria showed no obvious difference be-tween WH and WH + INCB treatment systems. Moreover,the inoculation of INCB was also beneficial to the in-crease of the biomass and nitrogen accumulation of the WH.关键词
