Abstract
The invention belongs to the field of industrial wastewater treatment, and relates to the application of a paint flocculant in circulating water for a wet paint-fog-removal system. The existing paint flocculants in circulating water for coating workshops are relatively single in compositions, most of the existing paint flocculants are PAM (pulse amplitude modulation)-series organic polymer flocculants, and the type of flocculants has a poor paint flocculation effect on low-resin high packing, rising paint slags are smaller in particles and difficult to refloat, and paint residues are easy to sink, so that the quality of circulating water is poor. According to the invention, by taking polyethylene oxide as main raw materials and adding an inorganic coagulant aid and a stabilizer into the polyethylene oxide, an aqueous solution is prepared. The paint flocculant has a strong adsorption bridging capability on paints, and by using the paint flocculant, the rising rate of non-sticked paint slags can reach above 95%, the rising speed of paint slags is high, and rising paint slags can stick together to form blocks, are low in moisture content and easy to refloat, and easily subjected to mechanical dehydration.
Description
Technical field:
The invention belongs to the Industrial Wastewater Treatment field, relate to a kind of flocculation agent that paints and remove the application in the coating cloud systemic circulation water in wet type.
Background technology:
When paint spray booth sprayed paint, the paint of crossing spray can be attached on water pump, pipeline, the fan blade because of having stickiness; Plug nozzles etc. cause circulating water channel to work, and painting quality can't guarantee; If directly discharge cycle water contains paint waste water and also can't estimate the harm that environment causes.In order to improve appearance of film, reduce harm to environment, adopt wet type to remove the coating cloud circulating water system mostly and caught and spray paint; In order to keep the operation of circulating water system long-term safety, cross and spray paint and must from recirculated water, separate, normally in water, add paint inharmonious dose and flocculation agent; The effect of wherein painting flocculation agent is to make inharmonious paint particle become bigger loose group with accumulation of impurities; Can accelerate the come-up of aggegation group, and make the lacquer slag firm and bonding, the enhance mechanical dewatering efficiency; Paint the electric charge of all right neutralized system of flocculation agent simultaneously, the ionic equilibrium in the maintenance system.
In recent years, owing to paint the variation of kind, the factors such as requirement raising of circulating water quality, people are also increasingly high to the requirement of paint flocculation agent.The existing paint flocculation agent composition that is used for application workshop recirculated water is more single; Mostly be PAM series organic polymer coargulator; Such flocculation agent is relatively poor for the paint flocculating effect of the low high filler of resin, and come-up lacquer solid impurity particle is less, is difficult for salvaging; And the easy sinking of lacquer slag, cycle water is relatively poor.In order to overcome the deficiency of existing paint flocculation agent, a kind of novel paint flocculation agent of necessary exploitation.
This project is intended to study a kind of novel paint flocculation agent, can be applicable to various types of paint, and sludge quantity strong to the adsorption bridging ability of painting, that produce is few etc., reduces use cost simultaneously.
Summary of the invention:
The purpose of this invention is to provide a kind of paint flocculation agent that various resinous type paint is all had better flocculating effect.This paint flocculation agent can make the come-up rate of inharmonious paint reach more than 95%, and ascent rate is very fast, and come-up lacquer slag can be bonded to bulk, is easy to salvage.
Another object of the present invention just provides this paint flocculation agent and removes the application in the coating cloud systemic circulation water in wet type.
Paint flocculation agent of the present invention is to be main raw material with the polyoxyethylene, adds the formulated aqueous solution of inorganic coagulant aids and stablizer.
Described polyoxyethylene molecular weight is between 2,000,000 to 8,000,000.
Described inorganic coagulant aids is a Tai-Ace S 150, iron(ic)chloride, a kind of or combination more than two kinds in polyaluminium sulfate, the Poly aluminum Chloride (PAC).
Described stablizer is an ethanol, Virahol, terepthaloyl moietie, a kind of in the Ucar 35.
The present invention paints the compound method of flocculation agent:
Molecular weight was mixed with the solution that mass concentration is 0.1-0.5% in 6 hours in 2,000,000-8,000,000 the polyoxyethylene stirring at normal temperature that is added to the water; Adding mass concentration more respectively is the inorganic coagulant aids of 1.0-4.0%, the stablizer of 5.0-10.0%; Fully stir; Mix, promptly obtain painting flocculation agent.
The application method of paint flocculation agent of the present invention:
Paint flocculation agent of the present invention needs to be used for inharmonious dose with paint, and the paint that is complementary can be melamino-formaldehyde class, clay class, polyvalent metal salt and biodegradable class for inharmonious dose.In containing paint waste water, add earlier inharmonious dose of paint, again waste water ph be adjusted to 6-9, treat in the waste water that paint particles is inharmonious fully after; In waste water, add paint flocculation agent of the present invention again; Mix and stirred 1-2 minute, leave standstill, paint particles promptly condenses the come-up caking; Salvage or the mechanical lacquer slag of scraping slag removal come-up through manual work, contain paint waste water and promptly can be recycled.Use paint flocculation agent processing of the present invention and contain paint waste water, painting flocculation agent, inharmonious dose of paint and containing the paint waste water volume ratio is 0.5-1: 1: 500.
The advantage of paint flocculation agent of the present invention is:
1, the paint flocculation agent of the present invention's preparation can be applicable to various types of paint, and is low to the adsorption bridging ability lacquer slag water ratio strong, that produce of paint, is prone to mechanical dehydration, can reduce use cost.
2, the application workshop recirculated water paint flocculation agent of the present invention's preparation can make the come-up rate of inharmonious paint reach more than 95%, and ascent rate is very fast, and come-up lacquer slag can be bonded to bulk, is easy to salvage.
Embodiment:
Be added to the water stirring at normal temperature 6 hours of the polyoxyethylene of certain molecular weight, add inorganic coagulant aids again and treat that it dissolves fully, add stablizer then, and fully stir, mix, promptly obtain painting flocculation agent.
