Ecological filler and ecological floating island apparatus based on ecological filler

Abstract

The invention relates to the field of water conservancy, environment and ecological restoration engineering, particularly to an ecological filler and an ecological floating island apparatus based on the ecological filler. The ecological filler comprises a mixed matrix, which mainly comprises composite particles, a rice straw filler and a composite bacterial agent. The ecological floating island apparatus comprises a floating island frame and fixing piles, wherein the upper surface of the floating island frame is covered with a photovoltaic power generation film with a storage battery block, the floating island frame is provided with first planting baskets, second planting baskets and a growth liquid box, the growth liquid box is arranged at the center of the floating island frame, the upper surface of a floating box is provided with an aeration device, the bottom portion of the floating box is provided with ecological filler baskets filled with an ecological filler, snails and mussels,the storage battery block of the photovoltaic power generation film is electrically connected to the aeration device, and the floating island frame is slidably connected to the fixing piles through hinges. According to the present invention, the apparatus has good water purification effect, and can improve and stabilize the sewage reclaimed water environment.

Description

technical field [0001] The invention relates to the fields of water conservancy, environment and ecological restoration engineering, in particular to an ecological filler and an ecological floating island device based on the ecological filler. Background technique [0002] At present, my country's water ecosystem has been seriously damaged, and the structure and function of more than 60% of rivers, lakes, wetlands and other ecosystems have been damaged to varying degrees. Ecological floating island is a kind of water ecosystem aimed at eutrophic rivers and other water ecosystems. It uses ecological principles to degrade the content of COD, nitrogen, phosphorus, etc. in water. Ecological floating islands adopt different shapes and different plants according to the specific conditions of the water body. type. Generally, floating plants or emergent plants are planted. These aquatic plants with developed root systems absorb nitrogen and phosphorus elements in the water through ...

AI Technical Summary

Problems solved by technology

However, most of the above-mentioned schemes have the following problems: (1) Relying on the natural aspiration of planted aquatic plants and no active aeration structure, this will affect the growth of plants and rely on plants to have comprehensive functions such as absorption, adsorption, and degradation of heavy metals in enriched water (2) The leaves of aquatic plants or other microorganisms in the water are not considered to increase nutrients or kill insects and bacteria of plants; (3) Since the floating island is fixed or tied with ropes, the lifting distance is small, Unable to follow the water level up and down for a long distance
