Embodiment Construction

[0040] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0041] The invention discloses a method for purifying the water body of eutrophic lake, such as figure 1 , Figure 13-15 shown, including the following steps:

[0042] S1. Use a special purification device walking on the water surface to purify the aquatic plants and algae on the water surface from the water body;

[0043] S2. After the cleaning of the dirt on the water surface is completed, the green planting modules 900 are arranged on the water surface at intervals. Each green planting module 900 includes a plurality of green planting units 901 connected to the supply buckets 904. Each green planting unit 901 and the supply bucket 904 A permeable drug bag 907 is installed on...

Abstract

The invention discloses a method for purifying the water quality of eutrophic lake water and a special purification device. The method is as follows: firstly remove pollutants in the water body; then arrange green plant modules on the water surface, and a plurality of green plant modules of each green plant module The planting unit is connected to the supply barrel through a catheter, and the osmotic medicine bag is installed on the catheter; the supply barrel and the osmotic medicine bag are filled with liquid medicine; after 5-7 days, the liquid is added to the supply barrel, and the osmotic medicine bag is filled. Replace the liquid medicine inside; repeat step S4 several times until the water quality test reaches the standard; A water pump is installed on the top, and the collection purifier and each power wheel are respectively connected to the water pump through the piping system. The invention fully controls the eutrophication of the lake, ensures that no rebound phenomenon occurs, and simultaneously reduces the input of manpower and material resources. The invention is applicable to the technical field of lake water quality eutrophication control.

Description

technical field [0001] The invention belongs to the technical field of eutrophication treatment of lake water quality, and in particular relates to a method and a special purification device for purifying the water body of eutrophic lake water. Background technique [0002] At present, due to the excessive discharge of people, the water quality of lakes is polluted, and the most serious pollution is eutrophication. Eutrophication is a water pollution phenomenon caused by excessive content of plant nutrients such as nitrogen and phosphorus. Excessive nutrients promote the proliferation of phytoplankton, such as cyanobacteria, diatoms and aquatic plants, in the waters, and sometimes the entire water surface is covered with algae. In this way, both animals and aquatic plants in the lake will die on a large scale. Nowadays, the treatment of eutrophication of lakes is the goal that people have been constantly exploring, and the lakes after treatment will rebound. It requires con...
