Abstract
This invention belongs to flocculating agent field. It is especially used to process flocculating agent of spray painting waste water and its application. Flocculating agent of spray painting waste water, of which characteristic is: it is made up of DZ-11 flocculating agent and DZ-12 polycoagulant. Wherein, DZ-11 has strong charge neutralization function. It can quickly neutralize oil paint particle electric charge, and remove glutinosity; DZ-12 polycoagulant has strong condensation, which can gather oil paint particle that lose glutinosity; proportion by weight of DZ-11 flocculating agent and DZ-12 polycoagulant is between 0.5-2:1. Spray painting waste water method, of which characteristic is: independently deposit above DZ-11 flocculating agent and DZ-12 polycoagulant, dissolve respectively, and utilize at then same time; adjust waste water PH to 8.5-10.5, add DZ-11 flocculating agent which is 5-8% of paint content of waste water at circulating water pump entrance; decrease glutinosity of circulating water that contains paint by using spray painting flocculating agent, add DZ-12 polycoagulant which is 6-10% of paint content of waste water at circulating water pump exit.
Description
Technical field
The invention belongs to the flocculation agent field, especially for flocculation agent and the application thereof of handling painting wastewater.
Background technology
Paint spray waste water treatment agent is to be used for handling useless lacquer that industry damp process painting wastewaters such as automobile, mobile phone and furniture produce.Present paint spray waste water treatment agent adopts single flocculant component, and it reclaims useless lacquer weak effect.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of new two-pack paint spray waste water treatment agent and application thereof are provided.
Paint spray waste water treatment agent is characterized in that: be made up of DZ-11 flocculation agent and DZ-12 flocculation agent, wherein, DZ-11 has strong charge neutralization, can be promptly in and the paint particles electric charge, eliminate viscosity; The DZ-12 flocculation agent has the intensive cohesion, and the paint particles that loses viscosity is gathered together; The weight ratio of DZ-11 flocculation agent and DZ-12 flocculation agent is 0.5～2: 1.
The painting wastewater treatment process is characterized in that: the described DZ-11 flocculation agent of claim 1, DZ-12 flocculation agent are independently deposited, and dissolving is respectively used simultaneously; When the waste water pH value transfers to 8.5-10.5, add the 5～8%DZ-11 flocculation agent that contains the lacquer amount in the flocculation agent waste water in the water circulating pump ingress; After containing lacquer recirculated water having used coating cloud flocculation agent visbreaking, add the 6～10%DZ-12 flocculation agent that contains the lacquer amount in the waste water in the water circulating pump outlet.
DZ-11 coating cloud flocculation agent
One, purposes: DZ-11 coating cloud flocculation agent is a kind of polymer colloid material, can be fast in and the coating cloud colloidal electric charge, eliminate its viscosity, thereby the coating cloud particle that prevented spray is attached on equipment and the pipeline.This product is the wet type special-purpose flocculation agent of circulating water system coating cloud that sprays paint
Two, character
Outward appearance: the little magma of transparent, pale blue
PH value: 3-4
Characteristic
1, visbreaking is extremely superior, and visbreaking speed is fast.
2, foam is few, and flco has suitable suspension.
3, adaptability is strong, to containing paint waste water concentration, pH value, temperature and paint kind wider adaptability is arranged all.
Three, using method and consumption
In order to obtain best result of use, the waste water pH value must keep 8.5-10.5, and adopts real-time addition method.When both carrying out paint spraying, add flocculation agent in the water circulating pump ingress.Certainly also can adopt and be interrupted regularly addition method.
Consumption: the 5-8% (adding method in real time) that contains the lacquer amount in the waste water.
The 0.5-1.5 ‰ of waste water total amount (being interrupted the method that regularly adds).
The DZ-12 flocculation agent
One, purposes and performance: the transparent colloid that the DZ-12 flocculation agent is made up of two kinds of amine high molecular polymers.This product has bridge formation, adsorption, small charged or neutral colloid particle is gathered together rapidly form the flco of comparatively large vol.Be used for the processing of trade effluent, especially cooperating DZ-11 coating cloud flocculation agent aspect the painting wastewater processing, to have more characteristic.
1, aggregation velocity is fast, and aggregate is big, and last buoyancy is good.
2, strong to high chroma, high-turbidity water processing power, be general flocculation agent 10-15 doubly.
3, easy and simple to handle, harmless.
Two, character
Outward appearance: water white transparency thick liquid.
PH value: about 7.
Three, using method and consumption: after containing lacquer recirculated water having used coating cloud flocculation agent visbreaking, add in the water circulating pump outlet.Certainly also can adopt and be interrupted regularly addition method.
Consumption: the 6-10% (adding method in real time) that contains the lacquer amount in the waste water.0.5% (interruption adds method) of waste water total amount.
The product suitable with more external brand performance compared, and the present invention has following beneficial effect:
1, consumption is few, and usage quantity is the 5-8% of over-sprayed paint fog, or the 0.5-1.5% of recirculated water total amount.The product consumption of external same-action is 5-15%.
2, visbreaking speed is fast, and foam is few.When using external product, need to use a large amount of defoamers, and cost an arm and a leg.
3, heavy metal ion, especially aluminium powder paint in the lacquer, the metal in the zinc rich paint there is not chemical action.
4, as environmentfriendly products, itself is nontoxic, and production process does not produce waste gas, waste liquid, waste residue yet.
