The invention discloses a blue-green alga, waterweed and bottom mud integrated collecting ship which comprises a hovercraft frame, a
weed mowing and conveying component, an alga drawing component and a mud suction component. The
weed mowing and conveying component, the alga drawing component and the mud suction component are movably connected with the hovercraft frame, and the hovercraft frame works by carrying one or more of the
weed mowing and conveying component, the alga drawing component and the mud suction component according to work needs. The blue-
green algae, waterweeds and bottom mud of a local
water area can be collected synchronously, stereoscopic
fishing is formed, and the
eutrophication harm of the blue-
green algae, the waterweeds and the bottom mud is eliminated synchronously. Single work can be carried out by carrying a
single component, pertinence is high, and efficiency is high. Due to the fact that the components are being carried for work, the components can be replaced immediately when a
mechanical problem occurs, influence to the work is small, and therefore the advantages of being high in stability, low in manufacturing cost, high in efficiency, high in maneuverability and the like are achieved.
