Multistage intercepting device for blue-green algae

Abstract

The multi-stage intercepting device comprises a first algae blocking device, a second algae blocking device and a third algae blocking device, the first algae blocking device comprises a floating pipeline which floats on the water surface and is arranged in a V shape, the upper portion of the floating pipeline is connected with an arc-shaped manger board, and the lower portion of the floating pipeline is connected with first algae blocking cloth; an intercepting and salvaging platform is arranged above the first algae blocking device, the second algae blocking device is arranged on the side, close to the intercepting and salvaging platform, of the overhauling operation platform and comprises a manger board, a stainless steel plate is connected to the manger board, and second algae blocking cloth is connected to the rear end of the bottom of the stainless steel plate through a pressing strip; the third algae blocking device is arranged on the inner side of the maintenance operation platform and comprises third algae blocking cloth. The three-stage algae blocking cloth is adopted for blocking, blocking of blue-green algae is more comprehensive, the algae blocking cloth is made of chinlon, the blue-green algae blocking rate is high, air permeability and water permeability are achieved, mounting and dismounting are convenient, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a cyanobacteria multistage interception device. Background technique [0002] Due to the progress of industrialized society and the extensive use of farmland chemical fertilizers, a large amount of wastewater containing nitrogen and phosphorus has entered the water body, resulting in eutrophication of the water body, causing the rapid reproduction of algae and plankton, forming algal blooms and floating on the water surface, which not only aggravates the deterioration of water quality , and have greater harm to aquatic animals such as fish, as well as humans and livestock. In severe cases, it will cause the death of fish due to hypoxia and seriously damage the ecological environment. [0003] There are many ways to remove blue-green algae, such as physical salvage, chemical algicide algae removal, biological treatment, etc. Among them, the blue-green algae sal...

AI Technical Summary

Problems solved by technology

Since the algae-blocking cloth cannot pass through the lake water, the water inside the algae-blocking cloth will easily become stagnant water, and the internal and external water flow cannot be replaced. After a long time, a large number of harmful bacteria will grow, causing the water quality to deteriorate, become muddy, and become smelly, resulting in Secondary pollution of water body

In addition, because part of the original algae blocking cloth is exposed on the water surface, it is easy to age after being exposed to sunlight, and it is difficult to disassemble, which affects the interception efficiency and the stability of the salvage system
