Light enhancing oxygen-enriched organism structural system for synchronously repairing eutrophicated water bodies in rivers and lakes and sediments in situ

Abstract

The invention relates to an ecological repairing method of eutrophicated water bodies in rivers and lakes and sediments, and provides a construction method of an organism structural system for synchronously repairing eutrophicated water bodies in rivers and lakes and sediments in situ by means of emergent aquatic plants, submerged plants, benthonic animals, fishes and microorganisms. The light enhancing oxygen-enriched organism structural system for synchronously repairing eutrophicated water bodies in rivers and lakes and sediments in situ has the double effects of synchronously and ecologically repairing polluted water bodies and sediments and providing habitats for aquatic organisms and microorganisms. The system comprises a lens reflective light enhancing surface water emergent aquatic plant survival area, a hollow prismoid free sliding middle water purifying area, a sediment-water interface submerged plant, a benthonic animal and fish survival area, a microorganism enriched intensified sediment purifying area and an oxygen-enriching fixed rod. The system provided by the invention can synchronously and ecologically repair the water bodies and the surface sediments, has the characteristics of good pollutant removing effect, stable and lasting treatment effect and the like, and is suitable for synchronously repairing water bodies in rivers and lakes and sediments in situ.

Description

1. Technical field [0001] The invention explores a method or process for in-situ simultaneous purification of polluted water and sediments and restoration of ecosystems by constructing a biological fabric system. 2. Background technology [0002] In recent years, due to the substantial reduction of vegetation in rivers and lakes, the substantial increase in the degree of masonry of bank slopes, and the increase in the amount of pollutants absorbed by rivers and lakes, the water bodies of rivers and lakes have been seriously polluted, and at the same time, pollutants have also accumulated in river and lake sediments. Coupled with the influence of excessive feeding of bait, fertilizers and chemicals in seine culture, the surface of river and lake sediments gradually forms a gray-black silt layer, which is rich in nutrients such as nitrogen and phosphorus and organic pollutants, becoming the eutrophication of rivers and lakes. important internal source. Studies have shown that...

AI Technical Summary

Problems solved by technology

These physical and chemical measures control the eutrophication of rivers and lakes through the mechanism of inhibiting the release of pollutants in sediments, and play an important role in the process of controlling sediment pollutants, but the investment is relatively large, and some technologies have been placed in water bodies for a long time , changing the shape of the sediment and recycling is a problem, and the pollutants are not degraded and removed fundamentally, and even cause secondary pollution of the environment, and large-scale implementation may have a negative impact on the ecosystem

Furthermore, the currently designed ecological restoration components of eutrophic rivers and lakes are mainly aimed at water bodies or sediments, and there are no related components for synchronous restoration of rivers and lakes water bodies and sediments
