Methods of Ecological Restoration of Barren Substrate Water

Abstract

The invention discloses an ecological barren-substrate water body remediation method. The ecological barren-substrate water body remediation method includes the following steps that 1, the soil texture at the water bottom is detected; 2, soil texture improvement is performed; 3, submerged plants are planted, wherein the planting density is 80-100 / m<2>; 4, the water level of a water body is improved; 5, the submerged plants are ecologically stabilized; 6, aquatic animals are put, namely the aquatic animals are put after the submerged plant coverage rate is above 60%; 7, the submerged plant coverage rate is above 60%, the water quality meet the set requirements, and remediation is completed. The ecological barren-substrate water body remediation method is low in carbon and free of secondary pollution and is environmentally friendly, the problem that submerged plants cannot normally grow on a barren substrate is solved, a construction period of ecological barren-substrate water body remediation is shorted, and the success rate of a project is improved.

Description

technical field [0001] The invention relates to water body ecological restoration technology, in particular to a method for ecological restoration of barren bottom water body. Background technique [0002] Water ecological restoration is to use the principles of ecosystems to restore damaged or eutrophic-polluted water ecosystem communities and structures, rebuild healthy water ecosystems, and restore and strengthen the main functions of water ecosystems. Mainly by planting various submerged plants with strong water purification ability and good ecological adaptability at the bottom of the restored water body, using the photosynthetic and oxygen release functions of submerged plants, supplemented by the configuration of aquatic animals, microorganisms, zooplankton, etc., to construct A healthy and stable water ecosystem enables the water body to achieve normal material circulation and energy flow, and has a certain self-purification ability. [0003] In the water ecological...

AI Technical Summary

Problems solved by technology

However, the water substrate of dredged and newly built lakes often cannot meet the planting and normal growth of submerged plants due to the poor fertility of the substrate, resulting in the problem that the coverage rate of submerged plants at the bottom is not high enough and the growth is poor, resulting in landscape The effect is poor, and it cannot play the role of photosynthetic oxygen production, water purification, and underwater landscape creation that submerged plants should have. Restoration works

[0004] Usually, the ecological restoration project of barren soil is mainly to improve the fertility of the substrate by adding a large amount of organic fertilizer, but this method is undoubtedly a secondary pollution to the damaged water body, which not only increases the difficulty of the water ecological restoration project and increases the construction cost, but also It is a high-carbon practice and does not meet the national low-carbon environmental protection requirements
