Example Embodiment

[0048] Example one.

[0049] A process for continuously filtering and adsorbing sewage using graphene, which includes the following steps:

[0050] a. Set up a filter adsorption mixture layer containing fillers and graphene materials;

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

[0052] c. The graphene material of the filtering adsorption mixture layer filters and adsorbs pollutants in the sewage, and the graphene material combines with metal fillers and / or metal oxide fillers for micro-electrolysis reaction;

[0053] d. Out of water.

[0054] The process of the present invention uses graphene materials to filter and adsorb pollutants in water, combined with metal fillers and / or metal oxide fillers for microelectrolysis; because graphene materials have a huge specific surface area, adsorption capacity and excellent electron transmission capacity, micro The electrolysis effect is much better than other carbon materials, and the am...

Example Embodiment

[0058] Example two.

[0059] The difference between the process of using graphene continuous filtration and adsorption to treat sewage in this embodiment is that the step b is specifically: input sewage in a tangential direction, and the sewage passes through the filtration adsorption mixture layer.

[0060] The sewage of the present invention enters the filtering adsorption mixture layer in a tangential direction, so that the water flow is spiral, which greatly strengthens stirring, reduces clogging and short circuits, and strengthens the treatment effect.

[0061] The other process steps of the process of continuously filtering and adsorbing sewage by using graphene in this embodiment are the same as those in the first embodiment, and will not be repeated here.

Example Embodiment

[0062] Example three.

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

[0064] In this embodiment, hydrogen peroxide is input as the oxidant to further enhance the treatment effect.

[0065] The other process steps of the process of continuously filtering and adsorbing sewage by using graphene in this embodiment are the same as those in the first embodiment, 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...
