Problems solved by technology

However, the traditional iron-carbon micro-electrolysis process is only suitable for low pH environment, and it is very easy to block and cause short circuit of water flow, which affects the treatment effect
[0006] At present, there is no technology to apply the graphene-metal micro-electrolysis process to sewage treatment. Therefore, it is urgent to provide an efficient and simple way to use graphene-metal micro-electrolysis process to treat sewage in view of the defects of the existing technology. process or device

Embodiment 1

[0049] A process utilizing graphene to continuously filter and adsorb sewage, comprising the following steps:

[0050] a. Set the filter adsorption mixture layer containing filler and graphene material;

[0051] b. Input the sewage, and the sewage passes through the filter adsorption mixture layer;

[0052] c. Filtration and adsorption of the graphene material in the adsorption mixture layer to filter and adsorb pollutants in the sewage, and the graphene material is combined with metal fillers and / or metal oxide fillers to perform micro-electrolysis reactions;

[0053] d. Out of water.

[0054] The process of the present invention adopts graphene material to filter and adsorb pollutants in water, and to carry out micro-electrolysis in combination with metal fillers and / or metal oxide fillers; because graphene materials have huge specific surface area, adsorption capacity and excellent electron transport capacity, micro The electrolysis effect is far better than other carbon ...

Embodiment 2

[0059] The process of using graphene to continuously filter and adsorb sewage in this embodiment is different from that in Embodiment 1 in that: the step b specifically includes: inputting sewage in a tangential direction, and the sewage passes through the filtration and adsorption mixture layer.

[0060] The sewage in the invention enters the filtration and adsorption mixture layer in a tangential direction, so that the water flow is in a spiral shape, the stirring is greatly strengthened, the blockage and short circuit are reduced, and the treatment effect is enhanced.

[0061] Other process steps of the process of using graphene to continuously filter and adsorb sewage in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0063] The difference between the process of using graphene to continuously filter and adsorb sewage in this embodiment is that the step b specifically includes: inputting sewage and hydrogen peroxide, and the sewage and hydrogen peroxide pass through the filtration and adsorption mixture layer.

[0064] In this embodiment, the treatment effect is further enhanced by inputting hydrogen peroxide as an oxidizing agent.

[0065] Other process steps of the process of using graphene to continuously filter and adsorb sewage in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of sewage treatment and in particular relates to a process and a device for performing continuous filtration and adsorption treatment on sewage by using graphene. The process comprises the following steps of: a. setting a filtration and adsorption mixture layer containing fillers and a graphene material; b. inputting the sewage and passing through the filtration and adsorption mixture layer; c. filtering and adsorbing pollutants of the sewage by using the graphene material of the filtration and adsorption mixture layer, and performing micro-electrolysis reaction by combining the graphene material with the metal fillers and / or metal oxide fillers; and d. outputting water. The micro-electrolysis reaction is performed by combining the graphene material with the metal fillers and / or metal oxide fillers, so very high purification efficiency is realized; and the process and the device have the characteristics of simple structure, stable operation, and simple and convenient operation and maintenance, and are applicable to various treatment occasions of sewage, drinking water and emergency water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a process and a device for continuous filtration and adsorption treatment of sewage by graphene. Background technique [0002] With the development of society, the treatment of industrial sewage and domestic sewage has become a very serious social task. In order to save water resources and protect the natural environment, my country has strict requirements on the discharge of industrial sewage, and attaches great importance to the recycling of various sewage. [0003] In the prior art, the methods of filtration and adsorption are often used to treat sewage. From the perspective of materials used, materials such as quartz sand are often used to intercept fine particles to achieve the effect of filtration, and activated carbon is used to adsorb various pollutants in water to reduce pollutants in water. In some cases, only activated carbon is used to filter and adsorb sewa...
