| 摘 要： | 研究了复合生态处理系统中不同单元颗粒物的构成差异，探讨了颗粒构成对其去除机制、粒径分布和去除规律的影响．结果表明，水环境对系统后端颗粒构成产生的影响明显高于对系统前端的影响．颗粒构的成差异决定无机颗粒沉降，有机颗粒分解、藻类被捕食、颗粒截滤依次在颗粒物的去除中占主导地位．不同水环境中，颗粒构成和去除机制的差异导致不同单元颗粒物去除规律的相应变化．

| Abstract: | The variations in particulate composition in different units of a multi-stages ecological treatment system have been investigated in this study. The effects of these variations on removal mechanisms, size distribution and removal rules of different water conditions are studied. Results of this study indicate that the effect of water conditions on particulate composition of the hind part of the system is more sensitive than that of the front. Inorganic particulates deposition, organic particulates decomposition, phytoplankton being eaten and filtration in turn are the major removal mechanisms of different units with the variations of particulate composition. The variations of particulate compositions and their removal mechanisms lead to the particle in different units take on different removal rules. |
