Embodiment 1

[0012] Mix 12 parts of potassium periodate, 8 parts of polyacrylamide, and 7 parts of malic acid, stir for 6 minutes, heat to 60°C, and add 70 parts of calcium aluminate powder, 30 parts of bentonite, and 35 parts of diatomaceous earth in sequence while stirring. After stirring for 20 minutes, the stirring was stopped to obtain a printing and dyeing sewage treatment agent.

Embodiment 2

[0014] Mix 15 parts of potassium periodate, 9 parts of polyacrylamide, and 8 parts of malic acid, stir for 8 minutes, heat to 80°C, and add 80 parts of calcium aluminate powder, 40 parts of bentonite, and 40 parts of diatomaceous earth in sequence while stirring. After stirring for 25 minutes, the stirring was stopped to obtain a printing and dyeing sewage treatment agent.

Embodiment 3

[0016] Mix 12 parts of potassium periodate, 6 parts of polyacrylamide, and 6 parts of malic acid, stir for 5 minutes, heat to 70°C, and add 65 parts of calcium aluminate powder, 25 parts of bentonite, and 35 parts of diatomaceous earth in sequence while stirring. After stirring for 20 minutes, the stirring was stopped to obtain a printing and dyeing sewage treatment agent.

Abstract

The present invention provides a printing and dyeing wastewater treatment agent and a preparation method thereof, and the printing and dyeing wastewater treatment agent comprises the following components by mass: 60-80 parts of calcium aluminate powder, 10-15 parts of potassium periodate, 5-9 parts of polyacrylamide, 6-8 parts of malic acid, 20-40 parts of bentonite and 30-40 parts of diatomaceous earth. The printing and dyeing wastewater treatment agent is capable of removing heavy metal ions, COD, dyes and other harmful substances in printing and dyeing wastewater, and also has the role of decolorization, deodorization, degreasing and sterilization, the decolorization rate can reach 95% or more, and the printing and dyeing wastewater treatment agent is simple preparation method in and low in cost.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a printing and dyeing sewage treatment agent and a preparation method thereof. Background technique [0002] Textile needs to be printed and dyed, and a large amount of wastewater will be generated during the printing and dyeing process. The sewage mainly contains dirt, grease, salt on textile fibers, and various sizing, dyes, surfactants, additives, and acids added during processing. Alkali etc. If the waste water is discharged directly without treatment, it will cause great pollution to people's domestic sewage. Contents of the invention [0003] In view of this, the present invention aims to provide a printing and dyeing sewage treatment agent and a preparation method thereof, so as to solve the problem that the printing and dyeing sewage is difficult to treat and pollutes the environment. [0004] In order to achieve the above object, technical solution of the present inve...
