| 摘 要： | 通过添加聚合硫酸铁(PSFe)降低水体中的活性磷,对水体中磷浓度、藻类生物量、碱性磷酸酶活性(APA)、类胡萝卜素/叶绿素a(Car/Chl.a)等指标随时间变化的情况进行了研究.结果表明,添加PSFe后,活性磷(RSP)迅速下降,藻类生物量和Car/Chl.a在短期内并没有显著变化.总碱性磷酸酶活性(TAPA)则随着RSP的下降而迅速升高,溶解性碱性磷酸酶活性(DAPA)上升幅度较小.结果表明,PSFe是一种优良高效的除磷剂,水体中TAPA、DAPA对RSP变化敏感,能在一定程度上指示水体中磷的变化. |

| Abstract: | The effects of polymeric ferric sulphate(PSFe) on the reactive soluble phosphorus(RSP),phytoplankton biomass,alkaline phosphorus activity(APA) and carotenoid chlorophyll a ratio(Car/Chl.a) were investigated.After adding PSFe,RSP decreased rapidly,while phytoplankton biomass and Car/Chl.a remained relatively constant in the short term.Meanwhile total alkaline phosphataseactivity(TAPA) sharply increased,and dissolved phosphorus precipitator.TAPA and DAPA were sensitive to RSP fluctuation,so they may be used a... |
