     Further, two adjacent algae grilles are connected through a cable 
     Compared with the prior art, the invention has the advantages as follows: 
     1. The lake reservoir water environment pollution restoration system can restore the content of oxygen dissolved in oxygen-free water bodies by the arrangement of aeration pipes to increase water mobility, thereby solving the problem of dissolved oxygen in eutrophic water bodies. 
     2. In the lake reservoir water environment pollution restoration system, emergent plants that are planted in the planting beds can solve the problem of water landscape, also oxygen that is generated by photosynthesis on the surface of leaves of emergent plants is delivered to water bodies via plant roots, so that the content of oxygen dissolved in water bodies is increased, and the roots of emergent plants in water bodies can absorb parts of eutrophication sources from water bodies. 
     3. In the lake reservoir water environment pollution restoration system, probiotic microbial flora attached to the fiber bundles can promote the absorption of eutrophication sources from water bodies by emergent plants, and also lead to the nitrification and digestion of pollutants in water bodies, thereby constructing depth-type ecological purified urban river water bodies. 
     4. In the lake reservoir water environment pollution restoration system, only algae are accommodated in the algae grilles, which have the effects of phosphorus removal, de-carbonization and odorization and can improve the clarity of lake reservoir water bodies. 
     5. The lake reservoir water environment pollution restoration system can achieve all-directional multi-level restoration of water bodies in lake reservoirs, as well as water-surface, in-water and water-bottom multi-level purification, with high restoration efficiency and convenience in maintenance.

     DETAILED DESCRIPTION OF THE INVENTION 
     The embodiments of the disclosure will be described in detail below, to facilitate the understanding of the disclosure by those skilled in the art, however, it should be understood that the disclosure is not limited by the embodiments, and for those skilled in the art, without departing from the spirit and scope of the disclosure defined by the claims appended, various modifications will become apparent, and all inventions utilizing the concept of the disclosure fall into the scope. 
     As shown in  FIG. 1 , a lake reservoir water environment pollution restoration system, comprises an ecological floating bed  1  floating on the surface of lake reservoir water, a plurality of planting beds  2  fixed on the ecological floating bed  1 , a plurality of adsorption nets  3  and reaction beds  4  fixed at the bottom of the ecological floating bed  1 , and a plurality of algae grilles  5  and aeration pipes  8  arranged at the bottom of lake reservoir water. 
     Wherein, the aeration pipes  8  are connected with a first output end of an air pump  6  through a vent pipe  7 , and a plurality of aeration holes  81  are arranged on the aeration pipes  8 , such arrangement can restore the content of oxygen dissolved in the oxygen-free water body and increase water mobility, thereby solving the fundamental problem of dissolved oxygen in the eutrophic water body. 
     As shown in  FIG. 2 , the planting beds  2  each comprise a planting bed body  21  and a planting groove  22  arranged on the planting bed body  21 , and planting holes  23  are uniformly distributed in the planting groove  22 . Emergent plants are planted in the planting holes  23  and can solve the problem of water landscape, also oxygen that is generated by photosynthesis on the surface of leaves of emergent plants is delivered to the water body via plant roots, so that the content of oxygen dissolved in the water body is further increased, and the roots of emergent plants in the water body can absorb parts of eutrophication sources from the water body. Further, two wall climbing bodies  24  are arranged on the two sides of the planting groove  22 , respectively. On the one hand, the wall climbing bodies  24  can be used for sculpting of the emergent plants, on the other hand, can avoid the cleaning problem caused by the spread of the emergent plants. 
     As shown in  FIG. 3 , the reaction beds ( 4 ) each comprise a support  41  fixed at the bottom of the ecological floating bed  1  in a vertically downward manner, and a plurality of fiber bundles  42  arranged on the support  41 , with probiotic microbial flora and coenzymes being attached to the fiber bundles  42 . The probiotic microbial flora can promote the absorption of eutrophication sources from the water body by the emergent plants, and also lead to the nitrification and digestion of pollutants in the water body, thereby constructing a depth-type ecological purified urban river water body. Also, the adsorption nets  3  are nitrogen/phosphorus-adsorbing films which can absorb nitrogen and phosphorus in water for the supply to the roots of the emergent plants. 
     Only algae are accommodated in the algae grilles  5 , algae have good effects of phosphorus removal, de-carbonization and odorization and can improve the clarity of lake reservoir water bodies. Further, two adjacent algae grilles  5  are connected through a cable  51 , to facilitate the cleaning of algae in the algae grilles  5  at the preset time. Furthermore, at least one inflation bag  52  is fixed on the algae grilles  5 , the inflation bag  52  is connected with an air delivery pipe  9  through an inflation pipe  91 , and the input end of the inflation pipe  91  is connected with a second output end of the air pump  6 . In the case of cleaning the algae in the algae grilles, the inflation bag  52  is inflated through the second output end of the air pump  6 , so that the algae grilles  5  automatically float on the water surface. In the case of putting the algae grilles  5  in water, all that is needed is to release the air from the inflation bag  52 , which is convenient and practical. 
     In summary, the lake reservoir water environment pollution restoration system can achieve all-directional multi-level restoration of the water body in the lake reservoir, with high restoration efficiency and convenience in maintenance.
