Embodiment Construction

[0025] The application will be further described below in conjunction with the accompanying drawings.

[0026] The optimal treatment method for removing heavy metals from seawater based on salinity and ion regulation is to put macroalgae into the heavy metal-polluted water body to be treated, and use the cell wall structure of macroalgae to contain a large number of active groups. Seaweed cells are mainly composed of polysaccharides, Composed of proteins and lipids, these components contain a large number of groups that can be combined with metal ions, and there is strong electrostatic adsorption and complexation coordination with metal ions, and the adsorption capacity for metal ions is strong, and through The ion channels and transporter carriers on the membrane transport the heavy metal ions adsorbed on the cell surface into the algae cells to achieve the purpose of removing heavy metal ions in the water.

Abstract

The invention provides an optimized treatment method for removing heavy metals in seawater based on salinity and ion regulation; specifically, coccoloba uvifera is put into the seawater with heavy metal ions; and the metal ions adsorbed on the surface enter algae cells through the structure of the cell wall, an ion channel on a cell membrane and a metal protein transporter, so that the aim of removing the heavy metal ions in the water body is fulfilled. The method is characterized in that before the heavy metal ions are removed, macroalgae are subjected to short-term pretreatment of salinity and deionization, diffusion of metal ions is increased by changing the permeability of algae cell membranes, and the ion competition effect is weakened; the algal cells have more sites for adsorption and absorption internalization of the heavy metal ions, so that the enrichment capacity of the algal cells on the heavy metal ions is improved, and the removal efficiency is improved. The average removal rate of the heavy metal ions in the water body reaches up to 80%, the highest removal rate reaches 90% or above, the treatment time is short, and the removal efficiency is high.

Description

technical field [0001] The application belongs to the application field of environmental biotechnology, and specifically relates to an optimal treatment method for removing heavy metals from seawater by Botrytis elongatum based on salinity and ion regulation. Background technique [0002] With the development of industry and the intensification of human activities, a large amount of heavy metal pollutants are discharged into natural water bodies. Heavy metals have become the main pollutants in oceans, lakes and groundwater, causing serious damage to the ecological environment and endangering human health. The traditional methods of treating heavy metal pollution in water are mostly physical and chemical methods, including precipitation method, chelating resin method, polymer trapping agent method, natural zeolite adsorption method, membrane technology, activated carbon adsorption process, ion exchange method, etc. These traditional treatment processes generally have disadva...
