Method and device for removing eutrophication material from lake water body

Abstract

The invention discloses a eutrophic substance removing method for lake water body and a device. A groove shaped water channel is arranged in the middle of a floating bed, and an aeration system, a flocculant automatic distribution and a feeding system, a stirrer set, a magnetic separation system and a settlement tank or a filtering net are arranged on the channel in front-to-back sequence, and the front end and the back end of the channel are respectively provided with a water quality automatic detecting device. When the floating bed walks in the water body, water flow passes through the channel and is added with the flocculant, stirred, and flocs is formed, absorbed by the magnetic separation system and removed. The eutrophic substance removing method for lake water body can be industrialized and continuously operated with a large water treatment quantity conveniently and simply. The method is quite suitable for the treatment of the eutrophic substances in lakes.

Description

technical field

[0001] The invention belongs to a treatment technology and equipment for lake water pollution, in particular to a method and device for removing eutrophication substances in lake water. technical background

[0002] Water is the most basic condition for human survival, life and production. The freshwater resources stored in lakes feed more than half of the world's population. Ensuring the safety of freshwater resources in lakes is a major issue related to the survival and development of human society. With the development of the economy, especially in the stage of rapid development in developing countries, economic growth has become the primary goal of the country, and environmental protection has been completely ignored or has become a secondary factor. In this case, the pollutants discharged into the lake are increasing day by day, while the purification ability of the lake itself is getting weaker and weaker, and the degree of eutrophication of the lake is...

Examples

Embodiment Construction

[0038] A pair of specific implementations will be described in detail below in conjunction with the embodiments of the present invention.

[0039] As shown in Figures 1 and 2, the entire device uses a floating bed 15 as a carrier, and can move in the lake through the rear driving force and the promotion of the horizontal stirring paddle 8. The aeration system is mainly composed of an air compressor 17, a gas equalization storage tank 18 and an aeration head 19, and the amount of air entering the water body is adjusted through a valve. The flocculant suspension configuration system is mainly composed of solid flocculant quantitative supply device 5 , clean water metering pump 7 , agitator 4 and dissolution tank 3 . The flocculant suspension dosing part is composed of an anti-corrosion metering pump 20 , a booster pump 22 and a suspension nozzle 21 . The mixing unit includes a multi-stage combination of a horizontal mixer 8 and a vertical mixer 10 . The magnetic separation sys...
