Description
Technical field
The present invention relates to a kind of processing method of waste water, in particular to a kind of processing method of phosphorized waste water.
Background technique
Phosphorized waste water is the pre-treatment of Treatment of Metal Surface, generally there is degreasing and rust removal, table tune, phosphatization passivation.There is simple phosphorus
Change is exactly to use phosphoric acid and sulfuric acid and nitric acid, also requires high dedicated bonderite (having aqua and powder product), powder product phase
To producing, mud is more.It is coated with and dusts and paint.If it is dusting, the waste water discharged is exactly that pre-treatment waste water includes phosphorized waste water.
In phosphorized waste water in addition to containing a large amount of phosphate, zinc ion, acid-base material and organic matter, according to production technology difference, sometimes
Also containing the pollutants such as heavy metals and surfactant such as a certain amount of nickel ion, copper ion or lead ion, complicated component, processing
Difficulty is larger.
Summary of the invention
The object of the present invention is to provide a kind of processing methods of phosphorized waste water, by the way that phosphorized waste water is sent into oil removal sand setting
Pond, flocculation basin, sedimentation basin, handle in sandfiltration pot after be sent into clear water reserviors, the various nocuousness in phosphorized waste water can be eliminated in this way
Substance does not pollute the environment so that reaching discharge standard.
, phosphorus to achieve the above object, the present invention provides a kind of processing methods of phosphorized waste water, comprising the following steps: (1)
Change and is handled in waste water feeding oil separation grit chamber；(2), the waste water in the oil separation grit chamber, which is passed through in flocculation basin, is handled；(3), institute
The waste water stated in flocculation basin is sent into sedimentation basin；(4), the liquid in the sedimentation basin is sent into clear water reserviors after being sent into sandfiltration pot filtering
In.
Compared with prior art, the beneficial effects of the present invention are by sending phosphorized waste water into oil separation grit chamber, flocculation
Pond, sedimentation basin are sent into clear water reserviors after handling in sandfiltration pot, can be eliminated the various harmful substances in phosphorized waste water in this way, be made
Discharge standard must be reached, do not polluted the environment, the present invention can be used among the processing of phosphorized waste water.
As a further improvement of the present invention, it is connected with conditioning tank between oil separation grit chamber and flocculation basin, can incite somebody to action in this way
Waste water homogeneous average, so that waste water, which enters in flocculation basin, preferably to react.
As a further improvement of the present invention, the waste water in the conditioning tank is pumped into flocculation basin by anti-corrosion, in this way
Water pump can be damaged to avoid the harmful substance in waste water.
As a further improvement of the present invention, limewash, PFS, PAM, PAC is added in the flocculation basin in this way can be more preferable
It eliminates the harmful substance in waste water and adjusts the pH value of waste water.
As a further improvement of the present invention, the waste water in the flocculation basin is handled by aeration stirring, so that wadding
The organic matter of waste water can be faster broken off in solidifying pond.
As a further improvement of the present invention, the pH value of the flocculation basin is 8, so that the reaction speed in flocculation basin
It is most fast.
As a further improvement of the present invention, the sedimentation basin is inclined-tube sedimentation tank, can make sedimentation effect more in this way
It is good.
As a further improvement of the present invention, intermediate pool is connected between the sedimentation basin and sandfiltration pot, it in this way can be with
So that the water in sedimentation basin first passes through intermediate pool excessively, mitigate the burden of sandfiltration pot, and make the filtering of sandfiltration pot
Effect is more preferable.
As a further improvement of the present invention, the sediment in the sedimentation basin is sent into sludge-tank, in the sludge-tank
Sediment be sent into plate and frame filter press in be made mud cake outward transport, can make in this way the sediment in sedimentation basin it is available effectively
Processing.
As a further improvement of the present invention, the filtrate generated in the plate and frame filter press is sent into conditioning tank at circulation
Reason, in this way can be to avoid filtrate contamination environment.
Detailed description of the invention
Fig. 1 is flow chart of the present invention.
Specific embodiment
The following further describes the present invention with reference to the drawings:
A kind of processing method of phosphorized waste water as shown in Figure 1, comprising the following steps: (1), phosphorized waste water be sent into oil separation grit chamber
Middle processing；(2), the waste water in oil separation grit chamber, which is passed through in flocculation basin, is handled；
(3), the waste water in flocculation basin is sent into sedimentation basin；(4), the liquid in sedimentation basin is sent into clear water after being sent into sandfiltration pot filtering
Chi Zhong；Conditioning tank is connected between oil separation grit chamber and flocculation basin；Waste water in conditioning tank is pumped into flocculation basin by anti-corrosion；
Limewash, PFS, PAM, PAC are added in flocculation basin；Waste water in flocculation basin is handled by aeration stirring；The pH value of flocculation basin is
