The packed bed 2 is arranged at the downstream of the aeration zone 1, under the action of gravity, water flow containing various pollutants firstly performs primary precipitation in a buffer zone 6 arranged on a river bed, plants in the buffer zone 6 primarily absorb part of pollutants, and then the flowing water flows into the aeration zone 1, the aeration zone 1 increases dissolved oxygen in water under the action of the turbine aerator 7, meanwhile, the buffer zone 6 of the aeration zone 1 performs primary precipitation and purification on the water flow, then the water body flows to the packed bed 2 along a ridge wall 5 between the aeration zone 6 and the packed bed 2, and the fillers of the packed bed 2 can effectively remove various pollutants in the water, so that a natural ecological system is constructed.

The plant bed 3 is located at the downstream of the packed bed 2, which means that aquatic plants are planted in a certain area of a riverway according to water level collocation, and the aquatic plants can be one or more of submerged plants 32, emergent plants 31 and floating plants 33. Furthermore, the plant bed is further laid with a layer of cobblestones (not shown in the figure), the cobblestones and the aquatic plants form the plant bed 3, so that the main reason for selecting the submerged plants 32, the emerged plants 31 or the floating-leaf plants 33 on the plant bed 3 for planting is that the plants have low requirements on the water environment and have certain landscape effect, the submerged plants 32 comprise goldfish algae or peltate yam and the like, the emerged plants 31 comprise acorus calamus, canna, purple yam and the like, and the floating-leaf plants 33 comprise water lily or potamogeton herb and the like. When water flows from the ridge wall 5 between the packed bed 2 and the plant bed 3 to the plant bed 3, the ridge wall 6 between the packed bed 2 and the plant bed 3 purifies the water again, and plants planted in the plant bed 3 and laid cobblestones further intercept pollutants such as nitrogen and phosphorus in the water body.

The artificial biological floating island 4 is mainly used for planting aquatic plants which have the decontamination capability and the landscape construction effect on the water surface according to different seasons. Swamp cabbage, water bamboo, flowers and the like are planted in combination in spring, summer and autumn, and water cress, lettuce and the like can be planted in winter. The unit forms natural biological habitats such as microorganisms, insects, fishes, birds, plants and the like, and is favorable for forming a biological chain to help the water body to recover so that the water body is further purified. The planting technology of the artificial biological floating island 4 is mainly soilless culture technology, and light biological floating island materials such as wood, foam and the like are adopted to fix all plants on the damaged water surface.

The ridge wall 5 is formed by stacking hollow bricks and/or stones at intervals, fillers or filter materials are laid on the hollow parts of the hollow bricks or the lands at the intervals or low aquatic grasses which are long in planting green period and have landscape greening value, such as manila grass, dichondra repens and the like, are evergreen in all seasons, the maintenance cost is extremely low, the landscape value is high, and water can be further purified when water flows through the ridge wall 5;

and/or the ridge wall 5 can also be paved with a layer of filter material by adopting materials with filtering and adsorbing effects, such as cobblestones, broken stones, ceramic materials or activated carbon, and the like, and can further treat the water body. The paving method of the cobble layer, the broken stone, the ceramic material or the activated carbon comprises the step of spreading the cobble layer, the broken stone layer or the ceramic material on the river bed in a dispersed manner after plants are planted. The sill walls may be the same or different between different processing units.
