Method and device for treating water by semi-floating type carrier-planting submergent plant

Abstract

The method of planting submerged plant in semi-floating carrier to treat water pollution includes the following steps: connecting seedling raising trays to the floated body in certain distance with rope, adding soil to seedling raising trays and transplanting submerged plant, and fixing the seedling raising trays under water. One relevant apparatus is also provided, which can restore submerged plant in eutrophic water, lower nutritive salt content in water and inhibit water bloom, so as to restore water quality. The method is simple and low in cost.

Description

technical field [0001] The invention relates to a method and a related device for controlling water bodies by planting underwater plants. Background technique [0002] Due to the development of industry and agriculture, the continuous increase of population and the intensification of urbanization, the pollutants entering rivers, lakes and other water bodies through surface water are increasing, and the freshwater ecosystems on which human beings depend are increasingly degraded, especially the problem of eutrophication. , has seriously threatened the sustainable development of social economy and human health. How to control the eutrophic water body that has been seriously polluted has become a major environmental problem facing our country. [0003] At present, the treatment methods for eutrophic water bodies mainly include: 1. Drainage and flushing, dredging; 2. Adding clay or coagulants; 3. Chemical algicides; 4. Adding microbial flora; 6. Restoration of higher aquatic p...

Problems solved by technology

However, in eutrophic water bodies, due to the limitations of transparency, water depth, bottom quality and other conditions, it is generally not possible to directly plant submerged plants, or the survival rate of submerged plants is not high, which will limit the popularization and application of such technologies

[0005] Although the Chinese patent application number 200510099736.X "A Method for Transforming Water Blooms into Underwater Vegetation Using Clay Condensation" reported that the removal of lake water blooms and the restoration of underwater vegetation are carried out at the same time, and the specimens take into account the control of water blooms and lake eutrophication. However, there are still the above-mentioned defects. For some very eutrophic water bodies or the limitations of water depth and bottom quality, it is difficult for submerged plants to adapt to grow, which will easily cause water body treatment. fail
