Waste water, sewage and the waste liquid generated during industrial production, wherein containing the industrial production materials outflowed with water, intermediate production
The pollutant generated in object and product and production process.Due in industrial wastewater containing a large amount of particulate matter not soluble in water and
It is dissolved in the chemical pollutant of water, if these industrial wastewaters are directly discharged to the external world, environment certainly will be polluted, influence human health.
The prior art is generally relatively simple to the processing method of waste water, not only haves the defects that treatment effect is bad, moreover,
Generally treated at present, and waste water is just directly discharged to the external world after meeting environmental requirement, without to handled waste water progress
It recycles, therefore, causes the wasting of resources, while polluted environment.
Summary of the invention
The invention mainly solves the technical problem of providing coating wastewater evaporation treatment process, for the useless of Coating Pretreatment
Water process, after treatment, the rinsing bowl reuse that 80% distilled water is directly pumped back to, 20% distilled water pump is sent to coating wastewater
Pure water making machine makees Pure water preparation, and the concentrate pump for remaining 1% is sent to concentrate bucket, can be avoided the wasting of resources, has reached ring
The effect of guarantor.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: provide a kind of coating wastewater evaporation
Treatment process uses neutralization water tank, evaporator, distilled water oil filter, concentrate bucket and pure water making machine, including following tool
Body step:
A, the waste water of Coating Pretreatment is directly entered wastewater trough；
B, the waste water of wastewater trough after the mixing of setting ratio enter neutralize water tank, waste water in and water tank in carry out filter residue,
PH value adjustment and flocculation treatment；
C, treated by neutralizing water tank, and waste water is inhaled into that evaporator is evaporated processing, and waste water must after evaporator is handled
The distilled water arrived；
D, distilled water automatically flows into oil water separator and does water-oil separating；
E, 80% distilled water after water-oil separating is directly pumped back to rinsing bowl reuse, and 20% distilled water pump is sent to pure water system
Standby device makees Pure water preparation；
F, by pure water making machine, treated that pure water is pumped into pure water slot and without phosphorus Phosphating Slot reuse.
In a preferred embodiment of the present invention, waste water is heated to obtain after 84 degree by both vapor compression by the evaporator
To 120 degree of high-temperature steam, then exchange be condensed into distilled water after be discharged.
In a preferred embodiment of the present invention, concentrate, the concentrate pump are also remained in the evaporator
It is sent to concentrate bucket.
The beneficial effects of the present invention are: coating wastewater evaporation treatment process of the invention, the waste water for Coating Pretreatment
Processing, after treatment, the rinsing bowl reuse that 80% distilled water is directly pumped back to, 20% distilled water pump is sent to pure coating wastewater
Water preparation apparatus makees Pure water preparation, and the concentrate pump for remaining 1% is sent to concentrate bucket, can be avoided the wasting of resources, has reached environmental protection
Effect.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, in which:
Fig. 1 is the flow diagram of a preferred embodiment of coating wastewater evaporation treatment process of the present invention.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
As shown in Figure 1, the embodiment of the present invention includes:
A kind of coating wastewater evaporation treatment process, using neutralizing water tank, evaporator, distilled water oil filter, concentrate bucket and pure
Water preparation apparatus, comprising the following specific steps
A, the waste water of Coating Pretreatment is directly entered wastewater trough；
B, the waste water of wastewater trough after the mixing of setting ratio enter neutralize water tank, waste water in and water tank in carry out filter residue,
PH value adjustment and flocculation treatment；
C, treated by neutralizing water tank, and waste water is inhaled into that evaporator is evaporated processing, and waste water must after evaporator is handled
The distilled water arrived；
D, distilled water automatically flows into oil water separator and does water-oil separating；
E, 80% distilled water after water-oil separating is directly pumped back to rinsing bowl reuse, and 20% distilled water pump is sent to pure water system
Standby device makees Pure water preparation；
F, by pure water making machine, treated that pure water is pumped into pure water slot and without phosphorus Phosphating Slot reuse.
Further, it is steamed after waste water is heated to 84 degree by the evaporator by the high temperature that both vapor compression obtains 120 degree
Vapour, then exchange be condensed into distilled water after be discharged.Wherein, concentrate, the concentrate pump are also remained in the evaporator
It is sent to concentrate bucket.
In conclusion coating wastewater evaporation treatment process of the invention, for the wastewater treatment of Coating Pretreatment, coating waste
