Description

A comprehensive restoration system for rivers and lakes

technical field

The utility model relates to the technical field of water body ecological restoration, in particular to a river and lake comprehensive restoration system.

Background technique

With the rapid development of the economy, a large amount of industrial wastewater and domestic sewage are discharged into surface water bodies such as rivers and lakes, and these wastewaters carry a large amount of nutrients. Due to the discharge of nitrogen, phosphorus and other elements, and the lack of necessary circulation in the water body, the algae and other plankton will multiply rapidly, the dissolved oxygen in the water body will decrease, the water quality will deteriorate, and fish and other organisms will die in large numbers, resulting in eutrophication of the water body. Destroy the aquatic ecological balance and form algal blooms. During the decay process of algae and other plankton residues, a large amount of nutrients such as nitrogen and phosphorus are released into the water for the new generation of algae and other organisms to use. Therefore, even if the eutrophic water body is cut off from the source of external nutrients, it is difficult for the water body to self-purify and return to a normal state.

Water ecological restoration refers to the technology used to restore polluted water to an unpolluted state by using the principles of ecology. Its characteristic is to give full play to the role of existing water conservancy projects, comprehensively utilize natural resources such as wetlands, tidal flats, ponds and embankment slopes in the watershed and artificial synthetic materials, and strengthen the self-recovery and self-purification capabilities of natural waters. According to the different principles, water ecological restoration technology can be divided into four categories: physical purification method, chemical purification method, biological purification method and natural purification method. The commonly used methods are biological purification method and natural purification method. The conventional methods of biological purification method are mainly biofilm technology and aeration and oxygenation technology. Natural purification method usually uses ecological floating island and aquatic animal and plant purification methods. In the utility model patent, "an ecological floating island device coupled with aeration" is disclosed, which combines the natural purification method and the biological purification method, through the combination of ecological floating island and fountain aeration technology, and microporous aeration technology. , make the most of the advantages of plant root contact oxidation, but if you need to improve the adsorption effect, you need to set up a large area of aquatic plants, the repair cost is relatively high, and only rely on aquatic plants to absorb nitrogen and phosphorus in the water body The nutrient-rich substances in the system water body are lacking in effect.
