Method for constructing inorganic artificial article floating island

Abstract

The invention discloses an inorganic man-made biological floating island, comprising the steps of: blending light inorganic material with inorganic adhesive (silicate, phosphate, borate or their combination, such as cement or clay, etc) and water; filling the mixture in a mould; curing, drying and moulding and then drawing it; placing in polluted water body, singly or after growing plants; purifying the polluted water body by growth of microbes and plants on the floating island. And the invention adopts inorganic materials, and has stable chemical property and friendly environment, and has no secondary pollution, and purifies the water body by coaction of plant and microbe membranes.

Description

technical field [0001] The invention relates to the field of water environment treatment and ecological restoration, in particular to a method for constructing an inorganic artificial biological floating island, which is suitable for water quality improvement in various eutrophic waters and urban landscape water bodies. Background technique [0002] Eutrophication of water bodies is a common problem in the current world water environment. Rapid economic growth has brought heavy loads to various natural water bodies. Under the combined effects of foreign substances and endogenous pollution, excess nutrients in water bodies have caused excessive phytoplankton reproduction, resulting in deterioration of water quality. The eutrophication of rivers and lakes is essentially a problem of ecosystem degradation, and new ways to control water pollution should be explored with ecological concepts, ideas, and methods.

AI Technical Summary

Problems solved by technology

As we all know, these artificially synthesized organic polymer materials are not found in nature, are easily damaged, are difficult to degrade under normal conditions, are difficult to recycle, and have the risk of secondary pollution

Extensive use of these materials will inevitably cause serious solid waste pollution

In this way, water pollution is transformed into solid waste pollution, the so-called "pollution transfer". This method of environmental governance is uneconomical and does not meet the requirements of sustainable environmental development.

In addition, the current research on the use of inorganic materials to make floating islands is still rare. Although individual studies can achieve good results, there are still insurmountable disadvantages in terms of manufacturing methods, costs, and use and maintenance, so it has not yet formed large-scale applications.
