摘要
试验采用浮床栽培香根草、在浮床周围悬挂人工介质、并定期向水体中投加光合细菌的组合技术,对湖泊富营养化水体进行了试验研究.试验结果表明,浮床组合生物技术对湖泊富营养化水体中的总氮、总磷具有明显的去除效果,能显著改善富营养化水体的水质;同时试验结果表明通过向水体中投放鱼类来延长生物链,更有利于提高浮床组合生物修复技术对富营养化水体的净化能力.
This paper studies the purification efficiency of eutrophical water by floating combination biological technology,which includes planting vetiveria zizanioids and hanging artificial medium on floating-beds,as well as adding photosynthetic bacteria in the eutrophicated water.It is shown through the experiment results that the floating combination biological technology removes TN and TP efficiently,and has a significant effect on improving water quality.It is also argued that long organism chain can improve the purifying effect of floating combination biological technology.
