Graphene-containing sewage treating agent and preparation method

Abstract

The invention discloses a graphene-containing sewage treating agent and a preparation method. The graphene-containing sewage treating agent is prepared from raw materials in parts by weight as follows: 10-20 parts of polyacrylamide, 5-10 parts of graphene, 8-15 parts of cashew nut shell oil frictional powder, 7-11 parts of animal skin glue, 10-18 parts of wollastonite, 6-12 parts of dolomite, 5-9parts of sapindus saponin, 6-10 parts of spodumene, 4-8 parts of tartaric acid, 4-7 parts of zinc borate, 3-7 parts of spina date seeds, 2-5 parts of calcium formate, 2-5 parts of light calcined magnesia, 1-3 parts of flint clay and 40-70 parts of water. The graphene-containing sewage treating agent is applied to sewage treatment and has better adsorption effect on heavy metal ions under the synergistic function of different materials, and the treating agent contains multiple natural components, thereby being low in toxicity and more environmentally friendly; the graphene-containing sewage treating agent is in a form of powder and is convenient to store, transport and use; meanwhile, the preparation technology is simple, the cost is lower, and no pollution is produced in a preparation process.

Description

technical field [0001] The invention relates to a sewage treatment agent and a preparation method, in particular to a sewage treatment agent containing graphene and a preparation method, belonging to the technical field of sewage treatment. Background technique [0002] Heavy metal sewage refers to the sewage containing heavy metal ions (such as cadmium, nickel, mercury, zinc, etc.) discharged from industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instruments. This kind of sewage is the most serious and harmful to the environment. One of the most harmful industrial wastewater to humans, its water quality and quantity are related to the production process. [0003] Under normal circumstances, heavy metals in sewage cannot be decomposed and destroyed, but can only be transferred through physical and chemical changes or change their physical and chemical forms; for this kind of sewage, the production proc...

Problems solved by technology

[0003] Under normal circumstances, heavy metals in sewage cannot be decomposed and destroyed, but can only be transferred through physical and chemical changes or change their physical and chemical forms; for this kind of sewage, the production process should be improved at the source, and no or less toxic heavy metals should be used , but this method cannot completely prevent heavy metals from enter
