Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an adsorption device for environmental protection water treatment. Background Technique

[0002] Sewage treatment methods include physical method, membrane filtration method, air flotation method, chemical method, electrochemistry method, biochemical method, etc. None of these methods can achieve the treatment of wastewater alone. Among them, the combination of physical method and chemical method is the most common. In the physical method, the most commonly used is the adsorption method. In the adsorption method, adsorbents are required. Developing an environmental protection water treatment material and its preparation method, and graphene, as a porous material, has special advantages in terms of mass, conductivity, thermal conductivity, dispersibility and stability due to its mechanical, quantum mechanical and electrical properties, making it have great potential in water treatment. The prepared environmental protection water treatment material has the advantages of good stability, quick effect, no secondary pollution, etc. Graphene is a two-dimensional crystal material composed of carbon atoms, with extremely high electrical conductivity, thermal conductivity and mechanical strength, and can adsorb gas and liquid molecules. These characteristics also make graphene widely used in the leading and application fields of new materials. Among them, the graphene water purifier is one of the important application fields of graphene materials. The graphene water purifier is a device for water treatment, purification and filtration through the special structure and action mode of graphene materials. Graphene materials have extremely high specific surface area and porosity, and can adsorb and filter harmful substances such as impurities, pigments, odors, heavy metals, etc. in water, making the water cleaner, safer and healthier. Due to the special structure and specific surface area of graphene, substances in water can be concentrated and adsorbed on graphene by physical adsorption, so as to achieve the filtration and removal of harmful substances in water. However, similarly, since graphene materials rely on the characteristics of multiple pores for adsorption and filtration, when there are too many large particle impurities in the sewage, the upper layer of graphene materials will be blocked, and at this time, the filter element of graphene materials will lose its filtering function, seriously affecting the treatment of sewage.
