The artifical fillers are hung under the plant floating bed then the remedial system combined by plant and microorganism came into being. The remedial effectiveness of the system was visibly better than that of the phytoremediation alone. So when the temperature is higher the remedial system combined by plant and microorganism is the preferable remedial technique to remedy contaminated water. In autumnal end and winterly outset, the temperature is lower, the plants begin to fade and die, and the plant must be harvested lest the relict of plant should contaminate water again. At the same time the technique combined by immobilized nitrogen cycling bacteria and microorganism which already existed in the water was used to remedy contaminated water.

将人工填料悬挂于植物浮床下，形成植物和微生物相结合的修复系统，其修复效果明显好于单独植物修复技术，因此温度较高时用植物和微生物共同结合的生物修复技术修复水体污染；秋末冬初温度较低时，植物开始死亡，必须将植物收割，以免植物残体造成二次污染，此时用固定化氮循环细菌和水体中原有微生物相结合的技术来修复水体的污染。
