Problems solved by technology

[0004] For the removal of suspended solids and colloids in black and odorous water bodies, chemical repair methods are commonly used at present. Although they have quick results and high removal efficiency, they are likely to cause secondary pollution and even destroy the original ecosystem, leading to ecological degradation.

preparation example Construction

[0071] The present invention also provides a preparation method of bionic ecological grass for purifying water, comprising the following steps: mixing iron powder, ferrous oxide powder and polyester fiber in proportion; making grass fiber 1 according to the manufacturing process of polyester fiber and the main fiber 2; then several grass fibers 1 are connected side by side on the main fiber 2 to form the biomimetic ecological grass. The mass ratio of the iron powder, ferrous oxide powder and polyester fiber is preferably 1-2:2-3:95-97, more preferably 2:2:96. In some embodiments, the diameter of the biomimetic ecological grass is 10-20 cm in the direction perpendicular to the main fiber 2 .

[0072] The present invention also provides a biomimetic system for water body purification, which is characterized in that it includes at least two biomimetic ecological grasses and at least one suspension rope 3; The connection is a conductive connection, and the two ends of the suspens...

Abstract

The invention relates to the technical field of water ecological environment protection, particularly to bionic ecological grass for purifying a water body, and a water body purification method, wherein the bionic ecological grass comprises grass body fibers and main fibers for integrally collecting the grass body fibers, the raw materials for producing the grass body fibers and the main fibers comprise iron powder, ferrous oxide powder and polyester fibers, and a mass ratio of the iron powder to the ferrous oxide powder to the polyester fibers is preferably 1-2:2-3:95-97. According to the present invention, after being electrified, the bionic ecological grass can adsorb the suspended matters and the colloids in a black odor water body so as to enhance the suspended matter flocculation andwater body clarification function.

Description

technical field [0001] The invention relates to the technical field of water ecological environment protection, in particular to a bionic ecological grass used for purifying water and a method for purifying water. Background technique [0002] In recent years, the country has vigorously developed urban modernization, and the level of industrial development has continued to accelerate, resulting in the status quo of low dissolved oxygen, low transparency, and high nitrogen and phosphorus pollution in urban rivers, resulting in the failure of aquatic plants to grow and the "desertification" of rivers. Black and odorous water is an extreme manifestation of organic pollution in water. Most of the black and odorous water is caused by the lack of oxygen in the water and the corruption of organic matter. When a large amount of organic pollutants enter the water body, under the biochemical action of aerobic microorganisms, a large amount of oxygen in the water body is consumed, and ...
