Ecological restoration system and method for eutrophication of reservoir water

Abstract

The embodiment of the invention discloses an ecological restoration system for eutrophication of reservoir water, including a salvage device for salvaging floating garbage, a three-dimensional measurement system for forming a three-dimensional monitoring map, an ecological floating island and a floating island frame for constructing a static purification system , in-situ cultivation of dominant microorganisms and directional release of dominant microbial populations, autonomously driven microbial self-circulation dominant culture devices, and aeration devices for maintaining the dynamic balance of dissolved oxygen in each zone; the present invention forms a three-dimensional, dynamic and static combination of ecological The repair system can achieve differential and dynamic purification and repair according to the three-dimensional detection results. The entire purification process is carried out in a biological way, without secondary pollution, and can be carried out after the treatment is completed. The harvesting of plants achieves the dual purpose of treatment and harvesting, and rationally utilizes the nutrients in eutrophic water bodies to achieve more effective and economical purification and restoration purposes.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of in-situ treatment of sewage, and in particular to a system and method for ecological restoration of eutrophication in reservoir water. Background technique [0002] All waters have a certain degree of self-purification ability. This self-purification ability comes from the dissolved oxygen in the water. If the water lacks oxygen, the waters must be seriously polluted. When a small amount of pollutants enter the waters, the dissolved oxygen in the waters will oxidize and decompose the pollutants into non-polluting inorganic substances and release them in the form of gas. The waters will be clean, and after a period of natural dissolution, the waters will recover and dissolve Oxygen content, so as to realize the circulation balance of the self-purification ability of the water area, and maintain the clean ecological environment of the water area. However, in recent years, with the...

Problems solved by technology

With the continuous increase of water environment management and water ecological protection, the current eutrophication of lakes and reservoirs is often restored by biological ecological methods. In the existing technology, the use of biological ecological methods to achieve water purification and restoration is mainly It is realized by plants. Since the growth of plants requires a stable environment, the restoration in the prior art is often static, and it is impossible to carry out differentiated treatment of vast and unevenly polluted waters, so that the effect of ecological treatment cannot be achieved. design requirements
