Three-dimensional ecological floating island for denitrification of water body by combining electro-catalysis and aquatic plants

Abstract

The invention discloses a three-dimensional ecological floating island for denitrification of a water body by combining electro-catalysis and aquatic plants. The three-dimensional ecological floating island comprises an implant and a floating body which are both of a circular ring structure, wherein the implant comprises a bottom plate I of a circular ring structure; the upper surface of the bottom plate is connected with an inner side plate and an outer side plate; the outer side plate is located on the outer ring of the bottom plate; the inner side plate is located on the inner ring of the bottom plate; the outer side plate and the inner side plate jointly form a planting groove for planting emergent aquatic plants on the upper surface of the floating body, and the planting groove is of an annular groove structure; the bottom of the outer side plate and the inner side plate are connected with a plurality of artificial aquatic plants; the floating body comprises a second bottom plate of a circular ring structure; a solar panel is arranged on the upper surface of the second bottom plate; the solar panel is electrically connected with a storage battery; and the storage battery is fixedly connected to the second bottom plate. According to the invention, the electrocatalysis technology, the aquatic plants and microorganisms in a filler matrix are combined and mutually influenced to jointly promote removal of pollutants, so removal effect is good.

[0002] The application number is 2015103797621, and the name of the invention is an electrochemical biological floating island for the purification of persistent pollutants in urban water bodies. In the disclosed technical solution, the entire system is anchored to the center of the lake or river, provided by floating plates. Buoyancy, carrying solid root bases to grow plant floating islands; powered by solar panels, driving propellers to cause water flow disturbances; and applying a constant current on the anode and cathode to achieve electro-adsorption and electro-catalytic purification of persistent pollutants, this technology The floating plants that can be planted in the scheme are limited, and the absorption of nitrogen and phosphorus by plants is limited. At the same time, floating and submerged plants are prone to hypoxia and death, causing secondary pollution to the water body. The effect of this technical scheme on water purification is worrying.
