| 摘 要： | 分别利用天然沸石、人造沸石和改性沸石对富营养化水体进行处理。结果表明,随着富营养化水体中N、P的增加,使富营养化程度增大,用沸石进行处理期间能形成生物膜,沸石能有效地去除水中的氨氮,其作用机理包括离子交换和生物硝化两种作用。覆盖着生物膜的沸石,对CODCr的去除率稳定在65%左右,对氨氮的去除率能稳定在90%左右。

| Abstract: | The eutrophication pond water was experimentally treated by natural zeolite,modifi ed zeolite and man-made zeolite respectively. The results showed that with the content of NH3-N and T P increasing,the degree of eutrophication would be increased,and the microorganisms would probably be grown on the surface of the zeolite. The function mechanism between zeolite and NH3-N would be both ion exchange and nitrifi cation reaction. Zeolite covered by biofi lm could remove CODCr and NH3-N with removal rate 65% and 90% respectively. |
