Problems solved by technology

[0006] Second, endogenous sediment pollution
[0007] The third is the impact of insufficient hydrodynamic conditions and poor water circulation
Water bodies that have lost their ecological functions often have reduced or completely lost fluidity, which directly leads to a decline in the reoxygenation capacity of the water body. The problem of hypoxia in some water areas or water layers is serious, forming hydrodynamic conditions suitable for the rapid reproduction of blue-green algae, and increasing the risk of algal blooms. cause water quality deterioration

Abstract

The invention discloses a water ecological comprehensive treatment system adopting a graphene photocatalysis net. The system comprises the following steps: selecting a polluted slow flow water body, scattering aquatic plants and a bottom net into a river, assembling the graphene photocatalysis net, installing a counterweight and a buoy of the graphene photocatalysis net, and arranging an optical fiber irradiation layer at the water bottom; assembling a cloth net floating frame; arranging a water circulating device which comprises a circulating water pump, a pipeline and a water distributor provided with a water outlet; and installing and fixing the graphene photocatalysis net in the polluted water body. According to the water ecological comprehensive treatment system adopting the graphenephotocatalysis net, attractive degree is high and treatment effect is good. The water body ecological restoration method has a good removal effect on pollutants, combines a photocatalysis technology with an aquatic plant treatment technology and has a good water body ecological treatment effect.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water ecological comprehensive treatment system using a graphene photocatalytic net. Background technique [0002] There are a variety of pollutants in natural water bodies, mainly including conventional organic pollutants that are difficult to biodegrade, such as COD remaining in the tail water of urban sewage treatment plants; persistent organic pollutants such as pesticides and herbicides that are brought into water bodies by rural non-point source pollution through runoff. Pollutants: Nitrogen, phosphorus and other pollutants that can easily cause eutrophication of water bodies. [0003] At present, the commonly used water treatment methods mainly include physical methods, including precipitation, flotation, filtration and reverse osmosis, etc.; chemical methods, mainly including neutralization, coagulation, redox, ion exchange and electrodialysis, etc.; biochemical...
