Problems solved by technology

[0003]At present, the technical means often used is to use bentonite to treat heavy metal wastewater, but the effect is poor
Further, the use of cetyltrimethylammonium bromide to modify bentonite can improve the treatment effect of organic wastewater and heavy metal wastewater, but it also creates new technical problems. Bromide ions have a lot of influence on the survival and reproduction of microorganisms. Subsequent further bio-decontamination has negative effects

example 1-9

[0033] Weigh each raw material according to the data of Example 1-Example 9 corresponding to Table 1, mix evenly; add 50 grams of water and stir for 30 minutes until uniform; dry at 110°C to constant weight, and then crush into 200 mesh particles to obtain this product Invented wastewater treatment agent.

[0034] Table 1: Wastewater treatment agent raw material formula table unit: gram

[0035]

example 10

[0037] Mix 100 grams of bentonite, 4 grams of tetradecyl sulfobetaine, 1 gram of graphene oxide, 2 grams of ferrous nitrate and 0.4 gram of isopropyl distearoyloxyaluminate; add 50 grams of water and stir 30 minutes until uniform; dried at 110°C to constant weight, and then crushed into 200-mesh particles to obtain the wastewater treatment agent of the present invention.

Embodiment 1-9

[0044] Embodiment 1-9 is analyzed:

[0045] Comparative embodiment 1 and embodiment 6 and embodiment 8, embodiment 1 adopts aluminate coupling agent, and embodiment 6 adopts silane coupling agent, embodiment 8 adopts titanate coupling agent, three tests The data vary greatly. It can be seen that the compatibility between the aluminate coupling agent and the amphoteric surfactant tetradecyl sultaine and bentonite is better, and the mutual support effect is better.

[0046] Comparative embodiment 1 and embodiment 5, the difference of the two is only: the tensio-active agent that embodiment 1 adopts is amphoteric surfactant tetradecyl sultaine, and embodiment 5 adopts cationic surfactant hexadecyl Trimethylammonium bromide; the COD removal rate of wastewater and the removal rate of nitrophenol organic matter vary greatly.

[0047] In summary,

[0048] The present invention takes bentonite as the core raw material, innovatively adopts the amphoteric surfactant tetradecyl sulfob...

Abstract

The invention discloses a wastewater treatment agent, a preparation method thereof and a metal wastewater treatment method. The wastewater treatment agent is prepared from the following raw materialsin parts by weight according to a conventional method: 100 parts of bentonite, 2 to 6 parts of tetradecyl sulphobetaine, 0.5 to 1.5 parts of graphene oxide, 1 to 3 parts of ferrous nitrate and 0.1 to0.7 part of isopropyldistearoyloxy aluminate. The wastewater treatment agent disclosed by the invention particularly has a good adsorption effect on heavy metals.

Description

technical field [0001] The invention relates to a waste water treatment agent, a preparation method and a metal waste water treatment method. Background technique [0002] Industrial wastewater includes production wastewater, production sewage, organic wastewater and cooling water. It refers to wastewater and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollution generated in the production process that are lost with water. things. There are many types of industrial wastewater with complex components. Among them, the treatment of organic wastewater and heavy metal wastewater is the most difficult, which has become a pain point in the industry. [0003] At present, the commonly used technical means is to use bentonite to treat heavy metal wastewater, but the effect is poor. Further, the use of cetyltrimethylammonium bromide to modify bentonite can improve the treatment...
