Combined device for lake wetland water body remediation

Abstract

The invention belongs to the technical field of water body remediation devices, and particularly relates to a combined device for lake wetland water body remediation. The combined device comprises a floating plate, an oxygen generation box, a biological treatment mechanism and a driving mechanism; a blocking block is arranged on the bottom wall of the floating plate, and a limiting assembly is arranged on the side wall of the floating plate; the oxygen generating box is positioned below the floating plate; the biological treatment mechanism is located below the oxygen generation box and comprises a net cage, wherein a remediation unit is arranged in the net cage; the driving mechanism comprises a poke rod, a stirring wheel and a driving motor, the poke rod is rotatably arranged on the oxygen generation box, the poke rod is connected with the stirring wheel through a rotating shaft, and the stirring wheel is located in the oxygen generation box; the driving motor is used for driving the poke rod to do circular motion in the vertical plane, and when the poke rod does circular motion in the vertical plane, the limiting assembly can drive the blocking block to intermittently move upwards under the abutting of the poke rod. The combined device for lake wetland water body remediation can continuously act under ice, and the effect of efficiently removing pollutants collected under ice is achieved.

Description

technical field [0001] The invention belongs to the technical field of water body restoration devices, and in particular relates to a combined device for lake wetland water body restoration. Background technique [0002] With the rapid development of social economy and the acceleration of urbanization, urban and some rural water bodies have been polluted to a certain extent, some lakes and rivers have experienced severe or mild eutrophication, the water quality has declined, the landscape has been destroyed, and the original ecological environment has been lost. Function, water pollution is a serious problem facing the world. Most of the sewage treatment uses chemical methods, such as using industrial flocculants for flocculation, etc. This treatment method not only has high engineering and operating costs, but also uses a large amount of chemical treatment agents to cause secondary pollution to the water body. [0003] During the freezing process of the lake in winter, the...

Problems solved by technology

Most of the sewage treatment uses chemical methods, such as using industrial flocculants for flocculation, etc. This treatment method not only has high engineering and operating costs, but also uses a large amount of chemical treatment agents to cause secondary pollution to the water body

[0003] During the freezing process of lake water in winter, the pollutants in the lake water are gradually collected into the subglacial water body driven by the "freeze concentration" effect, resulting in the pollutant load and concentration in the subglacial water body being much higher than the pollutant load in the ice body and concentration, the water body remediation device designed based on this pollutant fate rule can efficiently remove pollutants in water, but this kind of water body remediation device has not been disclosed in the prior art
