Example Embodiment

[0052] Example one:

[0053] A lake water ecological restoration method for reducing nitrogen and phosphorus is characterized in that it comprises:

[0054] Step 1: Use biotechnology to conduct biological treatment of the entire lake water area;

[0055] Step 2: Physically clean up the bottom silt at the revetment, the inlet water body and the main lake entrance to improve the oxygen content and transparency of the water body;

[0056] Step 3: Plant emergent plants with strong pollution absorption ability, submerged plants with strong purification ability, and floating plants with strong purification ability and ornamental properties on the revetment, near shore and main lake entrance respectively;

[0057] Step 4: Use artificial floating island technology in the central area of ​​the lake waters and construct a new healthy ecosystem for ecological management, so as to improve the water quality of some water bodies.

[0058] The first step includes the following steps:

[0059] Step 1: Us...

Abstract

The application discloses an ecological lake water restoration method with the effect of reducing nitrogen and phosphorus. The method comprises the following steps: firstly, performing biological treatment on the whole lake water area with a biological technology; secondly, performing physical cleaning on revetment and inshore water as well as bottom sludge at main lake inlets to increase the oxygen content and improve transparency of the water; thirdly, respectively planting emergent plants with high pollution absorption capability, submerged plants with high purification capability and floating plants with higher purification capability and ornamental capability on the revetment, the inshore and the main lake inlets; fourthly, performing ecological treatment on the central area of the lake water area by adopting the artificial floating island technology and constructing a new healthy ecological system to improve the quality of part of water. The method adheres to equal importance topollution control and water ecology, major pollution sources are effectively controlled and eliminated firstly, water ecological restoration is then implemented orderly, and finally, the healthy waterecological system is constructed; moreover, a continuous monitoring mechanism is established, and treatment and restoration effects are monitored.

Description

technical field [0001] The invention belongs to a water body pollution control method, and specifically refers to a lake water ecological restoration method for reducing nitrogen and phosphorus. Background technique [0002] The existing lakes lead to poor sensory perception of water mainly due to the following reasons: [0003] 1. Eutrophication of water body [0004] Eutrophication, also known as water bloom, refers to the phenomenon of water pollution caused by excessive plant nutrients such as nitrogen and phosphorus in lakes and other water bodies. Due to the enrichment of nitrogen and phosphorus nutrients in the water body, the rapid reproduction of algae and other plankton is caused, the dissolved oxygen content of the water body is reduced, and the pollution phenomenon of the decline or even extinction of algae, plankton, plants, aquatic organisms and fish is caused. A large number of dead aquatic organisms are deposited at the bottom of the lake, decomposed by mic...
