Description
Technical Field
The invention belongs to the field of biological treatment of pollutants, and mainly relates to a method for improving water quality purifying capacity of grass-type shallow lake wetland based on reaping submerged plants.
Background
In grass-type shallow lake wetlands, submerged plants occupy most of the water from the bottom to the surface of the wetland, and contribute significantly to the material circulation and energy flow of the water ecosystem. However, overgrowth of submerged plants can also cause serious problems to the water ecosystem, such as affecting the landscape function of the lake wetland, impeding the flow of water, even secondary pollution of water caused by self-decay, etc.
Currently, there are a number of patents for remediation of contaminated water by planting or managing aquatic plants. For example, CN101164916B proposes a method for treating a polluted water body by using a floating plant, duckweed, wherein the duckweed, the mixedly-cultivated water hyacinth and the water hyacinth occupy 70-90% of the water surface, and nitrogen, phosphorus and other pollutants in the water body are removed by absorption, adsorption and bioconversion. CN111606421a effectively solves the problems of difficult operation of the near-natural wetland in cold seasons and growth of crops in the year by establishing an aquatic plant purification system with alternation of cold seasons and warm seasons, and improves the water quality of the near-natural wetland. CN102249421a achieves the purpose of repairing eutrophic lakes by adjusting the area ratio of reed covered grass type lake water body and utilizing the purifying and transpiration effects of reed. WO/2008/081554 proposes to create floating islands on the water surface, improving the quality of eutrophic and contaminated water by comprehensively utilizing the repair functions of aquatic plants and microorganisms. However, the existing method for treating the polluted water body by utilizing the aquatic plant restoration technology is mostly focused on aspects of aquatic plant selection, planting and culturing modes and the like, and has the problems of single season, overlarge investment of manpower and material resources cost, large planting implementation difficulty and the like.
