A macrophyte is an aquatic plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish and substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife.
Refuse on water surface and cleaning ship for phytoplankton
InactiveCN104071309AOvercoming the disadvantage of being difficult to synchronizeAvoid knife entanglementWater cleaningWaterborne vesselsHull structureRefuse collection
The invention discloses a cleaning ship for phytoplankton. The cleaning ship is in a double ship structure and is composed of a driving wheel, a refuse guide mechanism, an impeller water distributor, a refuse tipping mechanism, a refuse cabin, a water plant cutting and collecting mechanism, a drive control system and other parts. When the ship works, the refuse in front of the ship is sucked into a tipping bucket refuse collecting area through a refuse guide mechanism and an impeller distributor, and then the refuse collected by the refuse tipping mechanism is poured into the refuse cabin on the ship; meanwhile, the phytoplankton and macrophyte are cut by an aquatic plant cutting mechanism, and then are transported to the refuse cabin through a water plant collecting mechanism (i.e. a rake type conveying crawler), after the refuse is full of the refuse cabin, a ship body docks, and the refuse is hung to a transfer trolley through a hoist. The cleaning ship is fast in speed of clearing away the refuse and phytoplankton on the water surface, and is capable of preventing the phenomenon that a cutter is twisted by the water plants.

Macrophyte-based bioplastic
A bioplastic composition may contain certain biodegradable and renewable components. In some examples, the bioplastic composition includes at least one kind of aquatic macrophyte biomass, which may contain a native composition of protein and carbohydrates, in a blend with one or more types of biodegradable or durable thermoplastic polymers. The aquatic macrophyte composition may provide a balance of both polymeric and reinforcing properties to the blended bioplastic not typically exhibited by terrestrial feedstock such as soy meal or corn starch. Such a bioplastic composition may be formed into molded articles using extrusion, injection molding, compression molding, or the like.

InactiveUS20090107912A1Enhancing ecological restorationEasy to removeScale removal and water softeningEnergy based wastewater treatmentEutrophicationCombined method
The present invention proposes a composite material which can rapidly and effectively remove algae and transform them into submerged macrophytes. The composite material is a mixture of two functional materials: one can grow into submerged macrophytes, and the other is clays or modified local soil particles which can flocculate algae, inhibit phosphorus release from sediments and act as the carrier of the above-mentioned seeds, earthnuts, buds, and roots of submerged macrophytes. In addition, the present invention proposes a physical-chemical-ecological combined method for improving water quality and enhancing the ecological restoration of eutrophic lakes using the above-mentioned material. By spraying the composite material to the lake surface, the new method can remove algae and turbidity through flocculation and complete the planting process simultaneously so that HABs and eutrophication are effectively controlled.
