Problems solved by technology

However, the recovery cost of powdered mycelium is high and the operation is very complicated. Too long mycelium adsorption time will cause the desorption of metal ions, so it is difficult to apply in practice.
At present, there are no public reports on the research and application methods of the adsorption of heavy metals by DSE complete mycelium balls
[0008] No matter what kind of microorganism is used, or whether it is used for adsorption or precipitation, when microorganisms deal with heavy metal pollution, they need to face a problem: how to provide a stable and safe "working environment" for microorganisms, microbial "employees" Because of its fragility and short lifespan, it is very easy to be wiped out during the work process (including death due to environmental deterioration, rapid demise due to failure to reproduce smoothly, etc.) or lost (taken away by water flow, etc.), resulting in governance failure

Embodiment 1

[0069] In this embodiment, the water body copper ion enrichment treatment device includes

[0070] The shell, which is a rigid structural part, has a window for the water supply body and bacteria to enter and exit;

[0071] The mesh layer arranged on the inner side of the shell has a pore structure that acts as a filter and allows water and bacteria to enter and exit;

[0072] The medium layer arranged inside the mesh layer includes a porous active material, and copper ions react with bacteria at the porous active material to realize the enrichment and recovery of copper ions. Copper ions include free copper ions and copper complex ions ;

[0073] The culture medium arranged inside the medium layer is used for the growth and reproduction of bacteria.

Embodiment 2

[0075] In this embodiment, the only difference from Embodiment 1 is that the mesh layer is a woven mesh layer.

[0076] Different from the foregoing embodiments, the dielectric layer includes one layer of dielectric units (the dielectric layer can also be provided with two layers of dielectric units, three layers of dielectric units, four layers of dielectric units, five layers of dielectric units, six layers of dielectric units, seven layers of dielectric units, etc. unit, eight-layer media unit, nine-layer media unit, or more layer media unit).

[0077] Different from the above embodiments, when the medium layer includes two or more layers of dielectric units, at least part of the adjacent media units on both sides are also provided with a barrier mesh layer, that is, when the medium layer includes two layers or two When there are more than one layer of dielectric units, such as when the dielectric layer is provided with two-layer dielectric units, three-layer dielectric uni...

Abstract

The invention discloses a device for enriching copper ions in water. The device comprises a shell, a mesh layer, a dielectric layer and a culture medium, wherein the shell is a rigid structural component, and a window through which water and culture come in and out is formed in the shell; the mesh layer is arranged on the inner side of the shell, and a porous structure with functions of achievinga filtering effect and enabling the water and culture to go in and out is formed in the mesh layer; the dielectric layer is arranged on the inner side of the mesh layer and comprises a porous active material; the copper ions and the culture are reacted in the porous active material to enrich and recover the copper ions; the culture medium is arranged on the inner side of the dielectric layer and is used for growing and propagating the culture. The enrichment and treatment effects of microbes on the copper ions in contaminated water are utilized, and the culture medium is actively provided forculturing and propagating functional bacteria and promoting the culture to react with the copper ions in the water, and the aims of enriching and treating the copper ions in the contaminated water areachieved. The device has excellent adaptability to various kinds of water and is excellent in microbial activity and high in contamination treatment ability.

Description

technical field [0001] The invention relates to a treatment device for water body polluted by heavy metal elements, in particular to a water body copper ion enrichment treatment device. Background technique [0002] The rapid development of industry has caused global environmental problems, and heavy metal pollution is one of the most harmful pollutions to the environment and human beings. Heavy metal pollution refers to environmental pollution caused by copper, lead, mercury, cadmium, cobalt and other heavy metals or their compounds, mainly caused by human factors such as mining, exhaust gas discharge, sewage irrigation and use of heavy metal products. Heavy metals are not easy to move and dissolve, and cannot be excreted and degraded after entering the organism, which will cause chronic poisoning. The degree of harm of heavy metals depends on the type, concentration, physical and chemical properties, valence and form of the element. When the concentration of metal elemen...
