Specific embodiment
In order to which those skilled in the art is made to more fully understand technical scheme of the present invention, With reference to embodiment
The present invention is described in further detail.
As shown in Figure 1 and Figure 2, the present invention including the use of the sequentially connected whirling well 1 for cyclone sediment of pipeline, be used for
Salvage separation purifier 2, the oil removal machine 3 for removing oil slick, the cooling tower 4 for cooling of magnetic flocculation group suspended matter；Also
Including being connect with whirling well 1 for launching the coagulant dispensing device 5 of coagulant, connect with 2 inlet channel of separation purifier
Flocculation aid dispensing device 6.2 inlet channel of separation purifier is provided with mixing stirring device after being located at flocculation aid dispensing device 6
7.Mixing stirring device 7 is static mixer.Static mixer includes tube body 71, and 71 both ends of tube body are respectively water inlet and water outlet
Mouthful；There are 2 groups of axial helical blades 72 in the tube body；The hand of spiral of two groups of helical blades 72 is opposite.Further include with
The dewaterer 8 that the connection of separation purifier 2 is dehydrated for the magnetic flocculation group suspended matter got of fighting each other；And and dewaterer
8 connect the sludge treatment device 9 for handling dewatered magnetic flocculation group suspended matter.Separation purifier 2 is communicated with horizontal flow basin
10, the horizontal flow basin 10 is communicated with sedimentation basin 11, and the sedimentation basin 11 connect 3 with oil removal machine.Separation purifier 2 is rare-earth magnetic disc
Detach purification of waste water device.Oil removal machine 3 is disc type oil removal machine.
Workflow is as follows：
A. turbid circulating water is subjected to cyclone sediment, and coagulant is added in precipitation process；Cyclone sediment is to utilize mechanical force
Control flow-shape and flow velocity, the precipitation of accelerating impurity and impurity that organic matter is made to be taken away with flow.Coagulant can will be in water
Colloidal particles mutually bond and flock together, convenient for later absorption salvage.Coagulant can select micro- magnetic flocculation agent
MMS-A。
B. the turbid circulating water after cyclone sediment is subjected to absorption salvaging, and adds in and help before absorption salvaging after cyclone sediment
Solidifying agent；Certain solid particles that coagulant has made it difficult to be separated from water are separated from the water out, but in water still in breast
Change or admixture need to just use flocculation aid to improve flocculent structure, make it more for these particles is made thoroughly to be separated from the water out
Add and salvaged convenient for absorption.Flocculation aid selects micro- magnetic flocculation agent MMS-M.It needs to be stirred mixing when adding in flocculation aid, preferably adopt
It is carried out with the mode of static mixing.I.e. by setting several helical blades in pipeline so that turbid circulating water forms several intersection rotations
Stream, using the power of flow as the energy of mixing.2 groups of helical blades, the hand of spiral of two groups of blades can be set in pipeline
On the contrary so that flow constantly generates the opposite whirlpool in direction and anti-whirlpool, to enhance mixing efficiency.
Impurity after absorption is salvaged is carried out dehydrating by magnetic squeezing dewaterer, and dewatered impurity is in Treatment of Sludge
Treatment of Sludge is carried out in equipment again.In order to preferably be handled, absorption can carry out advection sedimentation after salvaging.Advection sedimentation is
Using sedimentation basin so that contamination precipitation is in bottom of pond, and water is slowly flowed out from surface.
C. the turbid circulating water after being salvaged to absorption carries out oil removing；Oil removing is to utilize gravity different between grease and surface
Power draws oil slick, heavy oil and other organic liquids when passing through the water surface using equipment.
D. the turbid circulating water after oil removing is cooled down.Turbid circulating water can be recycled after the cooling period.
It the above is only the preferred embodiment of the present invention, it is noted that above-mentioned preferred embodiment is not construed as pair
The limitation of the present invention, protection scope of the present invention should be subject to claim limited range.For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, several improvements and modifications can also be made, these change
Protection scope of the present invention is also should be regarded as into retouching.
