Embodiment 1

[0026] Preparation of Agent A:

[0027] Aluminum-modified polyferric sulfate and 6501 nonionic surfactant are added to water successively in a mass ratio of 20:1, so that the total concentration of aluminum-modified polyferric sulfate and 6501 nonionic surfactant in the solution reaches 196.2% g Any value in the / ml range, then stirred at room temperature for 1 hour to completely dissolve it, and then the A agent solution was formed.

Embodiment 2

[0029] The preparation of agent B:

[0030] Add aluminum-modified polyacrylamide with a molecular weight of 9-12 million to water to make the concentration of the solution reach any value in the range of 0.1%-0.2% g / ml, such as 0.196, 0.1596, 0.1896, 0.296 g / ml, etc. , and then stirred at room temperature for 3 hours to make it completely dissolve, and it became the B agent solution.

Abstract

The invention discloses a paint mist coagulant and a preparation method thereof. The paint mist coagulant comprises an agent A and an agent B, wherein the agent A is an aqueous solution which is prepared by taking a macromolecular polymeric metal salt as a main component; the macromolecular polymeric metal salt is aluminum salt or ferric salt; and the agent B is an aqueous solution which is prepared from a polyamide substance with the molecular weight of 9000000-12000000. In the application, paint wastewater, the agent A and the agent B are mixed according to a volume ratio of 500: 2: 1, paint in the paint wastewater agglomerates and floats upwards, the paint is separated from water to obtain clear water, and the clear water is reused; the application method is that the agent A is added and uniformly mixed firstly and then the agent B is added; and the treated paint wastewater is fat-soluble treated paint wastewater and water-soluble treated paint wastewater. The chemicals used in the invention are wide in source; the defects that the conventional process of preparing the paint mist coagulant is complicated and many complicated and expensive chemicals are added are overcome; the treatment cost of the ordinary paint wastewater can be reduced to 0.25 Yuan per ton; and the paint mist coagulant can be widely applied to circulating water treatment of a wet-type paint mist removing system.

Description

technical field [0001] The invention relates to a chemical agent for removing paint in paint-containing wastewater and a preparation method thereof, in particular to a paint mist coagulant and a preparation method thereof. Background technique [0002] Suspending agent paint remover is an organic and environmentally friendly product with unique performance. It is used to decompose and remove the adhesion of various falling paints, condense and suspend paint slag, control the biological activity of circulating water, and maintain water quality. Adjust the pH value of the circulating water to the range of 8-10 to use the best slag removal effect. It is suitable for various painting lines such as automobiles, home appliances, mobile phone casings, furniture, and computer casings. [0003] After using the neutral paint mist coagulant in the wet spray paint treatment equipment, it not only effectively protects the environment, but also effectively eliminates the paint from adher...
