Method for improving water quality by using plant-microbe coupled ecological floating islands

Abstract

The invention provides a method for improving water quality by using plant-microbe coupled ecological floating islands. The method is characterized in that self purification capacity of a water ecosystem is promoted by constructing a plant-microbe coupled bio-community. The method comprises the following steps: an ecological enclosure is arranged along a river channel coast, so that the exchange rate between coastal water body and an open water area is reduced; a composite ecological floating island is arranged, and aquatic plants are planted on a floating bed; elastic three-dimensional filleris suspended under and around the floating bed; and an immobilized compound water purification agent is added to the root of the aquatic plants. According to the method, the repairing effect is obvious, the maintenance is convenient, and secondary pollution to water body is not caused during the treatment process; and the method is especially suitable for water body treatment of water flowing river channels with cement revetment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an ecological control technology for eutrophic river water pollution. Background technique [0002] In recent decades, with the rapid development of my country's social economy, the problem of water environment has become increasingly prominent, and the situation of water pollution is very serious. Water environmental pollution control and treatment has become a major environmental and social issue that needs to be solved urgently and the whole society pays close attention to. Due to the eutrophication of the water body and the hardening of the cement revetment along the river, many aquatic vegetation have been seriously degraded, and some aquatic plants in some water bodies have even disappeared. Exogenous input and endogenous release are the main sources of water eutrophication. When exogenous input is controlled, endogenous release can still cause...

Problems solved by technology

However, there are still some deficiencies in the current ecological floating island technology. For example, the reliability of the ecological floating island technology is unstable, and the effect is quite different in polluted water bodies in different regions;
