Purification system suitable for lake and river network

The utility model relates to a purification system suitable for lakes and river networks. The purification system comprises an adsorption assembly and an interception assembly, in practical application of the purification system suitable for the lake and river network, the purification system can be placed in the lake and river network firstly, and the emergent aquatic plant purification area can physically filter suspended particles in water; water entering the submerged plant purification area through the first permeable cloth can be biologically purified in the submerged plant purification area; according to the purification system suitable for the lake and river network, particulate matters in a water body can be purified through physical filtration and biological treatment at the same time, solid particulate matters and suspended particulate matters can be treated differentially, the solid particulate matters are filtered and intercepted by the emergent aquatic plant purification area, and the suspended
