| 摘 要： | 通过模拟实验研究了微生物对微囊藻残体的降解作用。水体内悬浮质和各主要形态磷浓度的变化结果表明：微囊藻的好氧分解符合一级动力学，其乳浮质和颗粒性磷的浓度呈指数关系递减，降解速度分别为０．２２７／ｄ和０．０８８／ｄ。经３２ｄ降解后，水体内的总溶解磷和可达总磷的５３％，而ＴＤＰ的主要成分为ＰＯ＾３－Ｒ。

| Abstract: | The model experiment of aerobic decomposition of Microcystis spp. (mainly including M. aeruginosa, M. flosaquae) in Taihu Lake was studied. The results show: the decomposition can be approximated by first-order kinetics. The particulate matter and concentration of partiele phosphorus are decreased exponentially. The rates of decomposition are 0.227d-1 and 0. 088d-1, respectively. After 32 days, experiment, the total dissolved phosphorus (TDP) accounts for 53% of total phosphorus (TP), and phosphate (PO43-) is the main component of TDP. During the aerobic decomposition of Microcystis, the water quality and the cycling of nutrient, especially the release of PO43- may not be overlooked. |
