Problems solved by technology
At present, there are bioreactor methods, membrane filtration methods, flocculant methods, etc. for the purification of sewage. The above methods can effectively purify sewage, but they all require huge processing equipment or expensive processing materials, and some even have ecological problems. Risks or secondary pollution to the environment cannot meet the current needs for sewage treatment

The invention discloses graphene sewage purifying agent, which is prepared from bentonite, diatomite, graphene and synergist through a conventional mixing method, wherein the mass part of the components is as follows: 20-50 parts of bentonite, 40-60 parts of diatomite, 20-30 parts of graphene, and 5-10 parts of synergist. The synergist comprises one type or multiple types from polymeric ferric sulfate, polymeric aluminium chloride and polyacrylamide. The graphene sewage purifying agent has the advantages of extensive material sources, simple preparation process and low cost, can efficiently purify the sewage when being added into the sewage as per the proportion, and has no secondary pollution.
Description
technical field [0001] The invention relates to a sewage purifying agent, in particular to a graphene sewage purifying agent. Background technique [0002] Water is the source of life. However, with the increase of urban population and the development of industrial and agricultural production, the amount of sewage discharge continues to increase, and the water environment continues to deteriorate, resulting in a serious shortage of water resources. Insufficient water sources in cities in many areas affect the physical and mental health of the people and become a serious constraint on economic development. Therefore, the issue of sewage purification has been paid more and more attention. At present, there are bioreactor methods, membrane filtration methods, flocculant methods, etc. for the purification of sewage. The above methods can effectively purify sewage, but they all require huge processing equipment or expensive processing materials, and some even have ecological pr...
