摘  要:
为研究低温对生态浮床水质净化效果的影响,引入陶粒作为浮床的基质,构筑了美人蕉-陶粒基质组合式生态浮床系统,研究在低温条件下其对微污染水体水质净化的效果特性。结果表明,在进水温度为0.5~15℃,进水DO浓度为4.94~6.65mg/L,水体交换时间为7d下,该生态浮床系统对水体中NH+4-N、NO-3-N、NO-2-N、TN、COD和色度的平均去除率为36.30%、77.37%、50.34%、52.56%、16.89%和70.99%。当水体的温度低于5.0℃,该生态浮床系统对水体中NH+4-N、NO-2-N、TN、COD和色度的去除效果均有所下降。

摘  要:
In order to investigate the influence of low temperature on purifying effect of ecological floating bed,light ceramsite is adopted as the matrix of floating bed and a Canna-ceramic matrix combined ecological floating bed system is constructed to study its purification effect for micro-polluted water under a low temperature condition.The results show that the removal rate values of the ecological floating bed system for NH+-4-N,NO-3-N,NO2-N,TN,COD,and chromaticity are 36.30%,77.37%,50.34%,52.56%,16.89%,and 70.99%,respectively under the condition that the water temperature is 0.5~15℃,the influent DO is 4.94~6.65mg/L and the water exchange time is 7d.When the water temperature is lower than 5.0℃,the removal effect of the ecological floating bed system on NH+4-N,NO-2-N,TN,COD and chromaticity will be decreased.
