Floating plant treatment device for eutrophic water body

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a floating plant treatment device for a eutrophic water body. The following scheme is proposed nowaiming at the problems that algae are small and fragile, are prone to be broken when fishing, and are not fished clean. The floating plant treatment device includes a hull, wherein the bottom of thefront end of the hull is connected with a supporting rod through bolts, the other end of the supporting rod is connected with a sleeve through bolts, and the bottom end of the inner part of the sleeveis hinged to a connecting rod, and the top of the connecting rod is hinged to a collecting cover. According to the floating plant treatment device, a method of using the collecting cover to collect plants floating on water surface cannot produce noise, the range of collection is wide, at the same time, floating plant spreading around cannot be caused, the collection effect is good, an arc-shapedbulge is arranged on the inner surface of a drainage ring, floating plant sticking and staying can be avoided, the collection speed of floating plants is further improved, device loading caused by floating plant accumulation can be reduced, the amount of treating floating plants by the device for one time is increased, and operation time is prolonged.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a device for treating floating plants in eutrophic water bodies. Background technique [0002] Eutrophication is a water pollution phenomenon caused by excessive plant nutrients such as nitrogen and phosphorus. However, due to human activities, after a large amount of industrial wastewater, domestic sewage, and plant nutrients in farmland runoff are discharged into slow-flowing water bodies such as lakes, reservoirs, estuaries, and bays, aquatic organisms, especially algae, will multiply in large numbers, making the population of biomass Changes in the number of species destroy the ecological balance of the water body. The algal blooms in the eutrophic water body are caused by the large number of algae in the eutrophic water body, resulting in a large number of blue-green algae, green algae, diatoms, etc., which block the sunlight of the water body and consume th...

However, due to human activities, after a large amount of industrial wastewater, domestic sewage, and plant nutrients in farmland runoff are discharged into slow-flowing water bodies such as lakes, reservoirs, estuaries, and bays, aquatic organisms, especially algae, will multiply in large numbers, making the population of biomass Changes in the number of species destroy the ecological balance of the water body. The algal blooms in the eutrophic water body are caused by the large number of algae in the eutrophic water body, resulting in a large number of blue-green algae, green algae, diatoms, etc., which block the sunlight of the water body and consume the water body. Oxygen in the interior causes the death of fish and further causes the deterioration of water quality

[0003] At present, the treatment of floating plants in eutrophic water bodies mainly relies on salvage to remove them. However, for floating plants that multiply in large quantities, such as cyanobacteria, green algae, and diatoms, the algae plants are small and fragile, and they are easy to break when salvaged. Not clean, at the same time, the algae coat is easy to attach to the surface of the fishing tool, causing the burden of fishing and affecting the efficiency of treatment
