This may be due to hydrolytic chelating, precipitation and the sediment or hydrobioes attachment, absorption etc. The honewort had stronger ability of accumulating La because of its large leaf surface that could attach La. The accumulating ability of snail and fish to La was relatively weaker but some organs of them had higher contents of La especially in the intestines, shell of snail, and in gill, internal organs, scales, head, bone of fish, rare in muscle. The total accumulating quantities of La in each component of simulated aquatic ecosystem were a decreasing order of: sediment >honewort>snail>fish, and the sequence of bio-concentration facter was as follows: honewort>snail>fish.
2金鱼藻对La有较强的富集能力,主要通过枝叶表面吸附、吸收而富集;螺蛳对La也有一定的富集,并主要分布于肠、壳中,螺头中积累相对较少;草鱼对La的富集能力相对较弱,进入鱼体的La主要集中在鳃、内脏、鳞及头、骨中,肌肉中积累量较少;按质量计,稀土元素La在模拟水生态系统各部分中的积累量依次为:底泥>金鱼藻>螺蛳>草鱼;各水生生物对稀土La的生物富集因子依次为:金鱼藻>螺蛳>草鱼。

The results indicate that (1) After acclimation and induction, Phosphorus Accumulating Organism not only has the characteristics of denitrification, but also has the characteristics of takeup phosphate in aerobic;(2) Denitrifying phosphate accumulating bacteria using NO3- as electron acceptor indeed existed in the conventional enhanced biological phosphorus removal system;(3) The facultative anaerobe seperated during the process of acclimation are Corynebacterium, Pseudodiphtheria corynebacterium, Staphylococcus and Moraxella; all of which can be functioned as denitrifying phosphorus accumulating to various degree.
试验结果表明:(1)好氧聚磷菌经驯化诱导后不但具有反硝化产氮特性,而且具有好氧聚磷特性;(2)在传统的A2O 工艺中存在有以NO3-为电子受体的反硝化聚磷菌;(3)在驯化过程中分离到的兼性厌氧微生物有棒状杆菌属、假白喉棒杆菌、葡萄球菌属及莫拉氏菌属,且都有不同程度的反硝化聚磷功能。
