The social and humane landscape and the natural environment are seriously damaged by various kinds of garbage with complex sources and various kinds, and the environment cost of tragic work is paid for the wastes. It is worth noting that the pollution of water garbage, which is an environmental pollution of water area and is not considered in the past, is more and more serious. The generation of these wastes is caused by rapid urbanization and industrialization process, development of tourism industry, thin environmental awareness of people and the like, so that the pollution of floating garbage in rivers, lakes and ports and even offshore is increasingly serious. The pollution of a large amount of water surface garbage not only destroys domestic water sources, but also influences the urban environment, and the pollution treatment and control of the water surface garbage are urgently needed to be enhanced.

Lemna minor (Lemna minor), also known as Duckweed, herba Spirodelae, Lemna minor grass, herba Spirodelae, and Lemna minor grass, is a water-surface lemma plant of the family Lemnaceae. Since the eutrophication of the water body and the excessive growth of the duckweed are caused after the wastewater containing a large amount of nitrogen and phosphorus in the domestic and industrial and agricultural production enters the water body, the duckweed is salvaged by adopting a salvage device in order to ensure the water surface to be clean.

Duckweed clearance recovery unit who puts into the market at present salvages duckweed and plastic refuse that floats on water in the lump, and the later stage goes again to pick out plastic refuse from the manual work in the duckweed of having retrieved, and manpower resources are wasted more to this mode, and efficiency is lower.
