Abstract
The invention provides a simple treatment and cyclic utilization method for electrophoresis on-line rinsing water. The method is as below: passing the high-concentration paint-containing waste water from an electrophoresis tank through an activated carbon filter for adsorption of organic matters like paint and a small quantity of metal impurities; filtering the waste water by a micropore precision filter into cleaning water; reusing the cleaning water in a washing water tank with the lowest paint concentration, wherein water in the washing water tanks with low paint concentration overflows to the washing water tanks with high paint concentration to compensation the washing water tanks, so as to realize cycling water purification. After adsorption saturation, active carbon in the activated carbon filter is used for coal stove combustion heat supply. The invention has the advantages that: the treatment is designed according to unicity of water pollution of electrophoresis paint washing waste water, active carbon is employed to adsorb organic matters like paint, and then precision filtering is utilized to guarantee cleanliness of the washing water and reach usage standard; the method is economical, simple and practicable; and active carbon with adsorption saturation can be used in thermal incineration and does not generate toxic substances.
Description
(1) technical field
The present invention relates to a kind of method of wastewater treatment, relate in particular to the simple and easy cycle for the treatment of of the online rinse water of a kind of electrophoresis and utilize method.
(2) background technology
Coating wastewater is mainly from industry such as automobile, machineries, in pretreatment procedure and the generations such as ability cathode electrophoresis operation and finish paint operation such as pre-degreasing, degreasing, table accent, passivation, phosphatizations.Contain main hazardous and noxious substances in waste water: nitrite, phosphoric acid salt, oil in water emulsion, tensio-active agent, electrodeposited paint film, alcohol, hydramine, resin, paint, pigment, dimethylbenzene equal solvent, ethylene glycol monobutyl ether, metal ion etc.General coating wastewater project scale 50T/H～200T/H left and right, waste water COD cr average out to 500～tens thousand of mg/l.Kind of waste water is many, complicated component, and water quantity and quality changes greatly.The method of administering coating wastewater both at home and abroad mainly contains the methods such as coagulating sedimentation, air supporting, sand filtration, activated carbon adsorption, electrocoagulation, FENTON oxidation, SBR, bio-contact oxidation.The method that the improvement coating wastewater adopts as requested is different.
(3) summary of the invention
The object of the invention is to design the simple and easy cycle for the treatment of of the online rinse water of a kind of electrophoresis and utilize method.
Technical scheme of the present invention: the simple and easy cycle for the treatment of of the online rinse water of a kind of electrophoresis is utilized method, the first rinse water of the method after with electrophoresis chamber is that high density contains paint waste water, after activated charcoal filter absorption paint waits organism and a small amount of metallic impurity, be back to use after water for cleaning after the micropore fine filtration device filters and contain the minimum cleaning sink of paint concentration again, the water between cleaning sink is by containing the paint low concentration of water to high density overflow make up water washing trough water level and circularly purifying water.In activated charcoal filter, the gac of absorption after saturated after drying, is used for the coal stove combustion heat supplying, and the paint wherein of having degraded divides, and has reduced the discharging of solid waste.
Superiority of the present invention: the unicity designing treatment of utilizing the water pollution of electrocoating paint Cleaning Wastewater own, utilize after the absorption of the paint such as Active Carbon in Organic part and recycle secondary filter and fall some macromolecular particles, just can guarantee the degree of cleaning of rinse water, reach again the standard of use, both economical, simple and easy practical and gac that adsorb after saturated again can also be used for adding thermal incineration, and without poisonous and harmful substances, produces.
(4) description of drawings
Accompanying drawing 1 is the structural representation in front of the present invention:
Wherein: the 1st, electrophoresis chamber, the 2nd, high density contains the paint cleaning sink, and the 3rd, washing bath two, 5th, contain the minimum cleaning sink of paint concentration, and the 6th, pipeline, the 7th, pump, the 8th, activated charcoal filter, the 9th, accurate filter, the 10th, overflow port.
(5) embodiment
as shown in Figure 1: the simple and easy cycle for the treatment of of the online rinse water of a kind of electrophoresis is utilized method, first cleaning sink after electrophoresis paint bath 1 is that high density contains paint cleaning sink 2 and connects pumps 7 by pipeline 6 and squeeze into activated charcoal filter 8, waste water extrudes activated charcoal filter 8 by the pressure of pump 7 and filters out some molecule particles by accurate filter 9 and get back to and contain the minimum cleaning sink 5 of paint concentration and add by pipeline 6 after activated charcoal filter 8 has adsorbed the paint part in waste water, containing minimum cleaning sink 5 water of paint concentration contains paint cleaning sink 5 by the overflow port 10 on each groove by lower concentration along the direction of washing bath 23 by overflow port 10 and contains paint cleaning sink 2 to high density and add step by step water.In activated charcoal filter 8, the gac of absorption after saturated after drying, is used for coal stove burning 5 heat supplies, and the paint wherein of having degraded divides, and has reduced the discharging of solid waste.
Claims (1)
1. the simple and easy cycle for the treatment of of the online rinse water of electrophoresis is utilized method, it is characterized in that: the high density of the method after with electrophoresis chamber contains paint waste water, after activated charcoal filter absorption paint waits organism and a small amount of metallic impurity, contain the minimum cleaning sink of paint concentration for being back to use after cleaning water again after the micropore fine filtration device filters, the water between cleaning sink is by containing the paint low concentration of water to high density overflow make up water washing trough water level and circularly purifying water; In activated charcoal filter, the gac of absorption after saturated after drying, is used for the coal stove combustion heat supplying, and the paint wherein of having degraded divides, and has reduced the discharging of solid waste.
