The application relates to the technical field of pharmaceutical preparations, in particular to application of Thalia dealbata in inhibiting a PI3K / Akt / mTOR signal path to slow down animal cell aging, which finds that Thalia dealbata can delay body aging after being applied to an aging model, and can slow down the animal cell aging process by inhibiting the activity of the PI3K / Akt / mTOR signal path, and effectively improves the efficiency of Thalia dealbata in slowing down aging.

The utility model discloses a multi-stage composite constructed wetland coupled ecological floating bed system, which belongs to the technical field of water pollution control and ecological restoration, and comprises a pretreatment unit, a multi-stage constructed wetland module and an ecological floating bed module, the multi-stage constructed wetland module respectively adopts zeolite, charcoal and oyster shell filler, and combines with reed, acorus calamus and other plants, and the ecological floating bed module is connected with the pretreatment unit. Suspended matters, COD (Chemical Oxygen Demand), ammonia nitrogen and total phosphorus are removed in a grading manner; the ecological floating bed module is arranged in a final-stage wetland water outlet area, cress and thalia dealbata are planted by adopting a modified polyethylene frame, and a load biological rope is suspended below the ecological floating bed module. Oyster shell filler chemical phosphorus removal, three-stage wetland-floating bed feedback coupling nitrogen removal and anti-blocking grading design are innovatively introduced, the effluent standard that COD is smaller than or equal to 30 mg / L, ammonia nitrogen is smaller than or equal to 2 mg / L and total phosphorus is smaller than or equal to 0.5 mg / L is achieved, and meanwhile the operation and maintenance cost is reduced through economic crop planting. The system has high efficiency, long-term effect and resource benefit, and is suitable for treatment of domestic sewage, agricultural non-point source and river eutrophication water.

The present invention relates to the application of aquatic plants in water purification and a method thereof, wherein the aquatic plants are composed of emergent plants, floating leaf plants and submerged plants to form a plant restoration ecosystem, wherein the emergent plants are selected from at least one of canna, loosestrife and lily; the floating leaf plants are water lilies; and the submerged plants are Vallisneria. Compared with the prior art, the present invention conducts experimental research on dozens of aquatic plants, determines the water purification capacity of each, and then forms a plant restoration ecosystem with high purification efficiency for water bodies by combining various types of aquatic plants.
