Description

Technical Field

[0001] The present invention belongs to the technical field of water ecological restoration, and in particular relates to a water ecological restoration system and a restoration method. Background Art

[0002] In recent years, with the rapid development of industrial and agricultural production and the acceleration of urbanization, the amount of industrial wastewater and domestic sewage discharged into water bodies and lakes has continued to increase, large areas of vegetation in lakes have disappeared, the degree of eutrophication of water quality has become increasingly serious, and algae have reproduced rapidly. Some of these algae will emit a fishy smell. When the algae die and decompose, the COD and BOD values ​​in the water will surge, the water quality will deteriorate, and the transparency of the water body will be greatly reduced.

[0003] At present, the existing water ecological restoration usually restores and repairs the degraded or damaged water ecosystem through a series of measures. However, the traditional water ecological restoration method can only temporarily improve the water environment and cannot be recycled well. Therefore, a water ecological restoration system and restoration method are proposed to improve the water environment in the long term to meet people's needs. Summary of the invention

[0004] The purpose of the present invention is to provide a water ecological restoration system and a restoration method, aiming to solve the problem that the existing water ecological restoration usually restores and repairs the degraded or damaged water ecosystem through a series of measures, but the traditional water ecological restoration method can only temporarily improve the water environment and cannot be recycled well.
