Embodiment 1

[0026] An in-situ low-carbon submerged water ecological restoration method for water bodies, the method includes the following steps:

[0027] S1. Bottom sludge disinfection and activation: use Chinese herbal medicine disinfection activator with a concentration of 400mg / L, spray it evenly on the entire bottom of the pool, and use a dosage of 100ml / ㎡. After disinfection, let it stand for 30 minutes, and then activate the bottom sludge;

[0028] S2. Planting of submerged plants: Plant evergreen submerged plants in all seasons, with a planting density of 50 plants / ㎡ and a planting area of ​​20%;

[0029] S3. Temporary auxiliary oxygen-enriched aeration: Introduce high-concentration oxygen into the water, with an oxygen concentration of 90%, for 2 hours. While aerating, add sodium percarbonate solution to the water, with a concentration of 18%;

[0030] S4. Adding algae-controlling daphnia: measure the pH of the pool water before putting in algae-controlling daphnia, according to ...

Embodiment 2

[0039] An in-situ low-carbon submerged water ecological restoration method for water bodies, the method includes the following steps:

Abstract

The invention discloses an ecological restoration method for in-situ low-carbon submerged water in a water body. The ecological restoration method disclosed by the invention has the benefits that a chemical agent is not used, so that the secondary pollution cannot be caused to an environment; the aim is to establish a virtuous cycle of biodiversity and build a healthy and stable underwater ecosystem for 'indigenous micro-organisms+zooplanktons+protozoans+submerged plants+aquatic animals', so that the water body has ecological self-purifying capability; an underwater landscape system is constructed, so that a long-term and stable purifying effect is achieved; meanwhile, the ecological restoration method has a certain ability to resist external pollution; bottom mud is fixed and mineralized,and nutritive salt and other substances in the bottom mud are gradually absorbed and transferred; compared with a general technology, the ecological restoration method requires no silt removal, no any additional water circulation system, no additional land occupation, no equipment, no machine room, no subsequent power consumption, no pipeline and the like; a restored water body environment can form a self-restoration system and an internal hydrodynamic ecosystem as well as a self-purifying system; the pollution is not required to be diluted by relaying on the change of water, so that the costis low.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an in-situ low-carbon submerged water ecological restoration method for water bodies. Background technique [0002] With the development of social economy and the rapid growth of population, a large amount of nutrient-rich domestic sewage, industrial wastewater, and farmland sewage are discharged into the freshwater system, resulting in eutrophication, water quality deterioration, and odor, which seriously affect the environmental quality. . [0003] The current technologies for water pollution remediation mainly include: [0004] (1) Sewage interception based on exogenous pollution control, sewage diversion, treatment of sewage denitrification and phosphorus removal, reduction of phosphorus discharge in domestic sewage, initial rainwater interception, etc.; and dredging and nutrient salt based on endogenous pollution reduction A series of measures such as pass...
