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; When the purification ability of floating island plants reaches saturation or when it is the season of apoptosis, the effect is poor; most ecological floating island technologies lack effective coupling with safe functional microbial ecological restoration technology

Embodiment Construction

[0018] The technical solutions of the present invention will be described in further detail below in conjunction with specific embodiments.

[0019] The present invention can be realized by the following methods:

[0020] 1. Set up ecological enclosures

[0021] According to the width of the river channel and the width of the floating island to be set, use tarpaulins (water barriers) to set up ecological enclosures, reduce the exchange rate between water bodies in the enclosure area and open water areas, and increase the residence time of water bodies. The setting of ecological enclosures does not Normal water traffic should be affected. The realization of the ecological enclosure is to fix moso bamboo or wooden piles in the water body, hang one end of the waterproof cloth (water curtain) on the moso bamboo or wooden piles, or tie one end of the waterproof cloth (water curtain) to a rope to suspend the floating body to make the floating body Floating on the water surface, th...

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...
