Description
Technical field
Hard technology field is removed the present invention relates to sewage disposal, particularly a kind of high rigidity removes hard pre-processing device.
Background technology
Existing sewage disposal hard-removal system, the hardness gone in water removal using three traditional headers mostly.In actual fortune
During row, there is following weak point：Three traditional headers are very poor for the removal effect of high rigidity sewage, the hardness of water outlet
It is very high, there is very big impact for whole system, the operating cost of system is increased, three headers can also after operation a period of time
There is hardened phenomenon, increased the number of times of the maintenance down of equipment, influence the normal operation of whole system.Accordingly, it would be desirable to one
Plant stable, the not hardened equipment of energy.
The content of the invention
To solve the above problems, the present invention provides a kind of high rigidity and removes hard pre-processing device, to overcome current technology to exist
Deficiency.
The purpose of the present invention is achieved through the following technical solutions:
A kind of high rigidity removes hard pre-processing device, including water-in flange, mixing pit mixer A, mixing pit A, baffle plate A, leads
Flow tube, central tube, preliminary sedimentation tank, mixing pit mixer B, mixing pit B, baffle plate B, flocculation basin mixer, flocculation basin, water inlet pipe pass through
Water-in flange is connected with mixing pit A, and mixing pit A is connected by baffle plate A with mozzle, and mozzle is connected by central tube with preliminary sedimentation tank
Connect, preliminary sedimentation tank is connected by pool wall opening with mixing pit B, mixing pit B is connected by baffle plate B with flocculation basin, after flocculation basin connection
Continuous process section.
Preferably, preliminary sedimentation tank is provided with the equipment, the dosage of medicament can be reduced, be stabilized subsequent treatment.
It is further preferred that having used polymeric coating layer on the pool wall surface of preliminary sedimentation tank, it is therefore prevented that except pool wall in hard process
Hardened problem.
Beneficial effects of the present invention are：
Preliminary sedimentation tank is provided with 1 present invention, ion occurs because the hardness in sewage is very high, when dosing forms precipitation wraps up in band
Effect, so as to reduce the dosage of medicament.
Preliminary sedimentation tank is provided with 2 present invention, substantial amounts of hardness is eliminated due to first precipitating so that enter next section except hard
Sewage hardness reaches a relative stationary value, is stabilized subsequent treatment.
In 3 present invention, polymeric coating layer is used in the inner surface of preliminary sedimentation tank, made sediment on pool wall without crystallization
Point, so as to prevent, except the hardened problem of pool wall in hard process.
Brief description of the drawings
The present invention is described in further detail below according to accompanying drawing.
Fig. 1 is that high rigidity of the present invention removes hard pre-processing device block diagram.
In figure：1st, water-in flange, 2, mixing pit mixer A, 3, mixing pit A, 4, baffle plate A, 5, mozzle, 6, central tube,
7th, preliminary sedimentation tank, 8, mixing pit mixer B, 9, mixing pit B, 10, baffle plate B, 11, flocculation basin mixer, 12, flocculation basin.
Specific embodiment
As shown in figure 1, a kind of high rigidity of the present invention removes hard pre-processing device, including water-in flange 1, mixing pit is stirred
Mix machine A2, mixing pit A3, baffle plate A4, mozzle 5, central tube 6, preliminary sedimentation tank 7, mixing pit mixer B8, mixing pit B9, baffle plate
B10, flocculation basin mixer 11, flocculation basin 12, water inlet pipe are connected by water-in flange 1 with mixing pit A3, and mixing pit A3 is by gear
Plate A4 is connected with mozzle 5, and mozzle 5 is connected by central tube 6 with preliminary sedimentation tank 7, and preliminary sedimentation tank 7 passes through pool wall opening and mixing pit
B9 is connected, and mixing pit B9 is connected by baffle plate B10 with flocculation basin 12, the connection subsequent technique section of flocculation basin 12.
When specifically used, sewage enters mixing pit A3 by water-in flange 1, is added in mixing pit A3 except hard medicament,
Under the stirring of mixing pit mixer A2 (mixing speed R=60rpm), medicament and sewage is set sufficiently to mix, mixed dirt
Water enters preliminary sedimentation tank by baffle plate A4, and the sediment and sewage that will be formed are separated, to remove the most of hardness in sewage, after being
It is continuous further to remove hard ready, due to employing polymeric coating layer in the pool wall of preliminary sedimentation tank 7, so in hardness very high and greatly
Also be not in situation of the crystal absorption on pool wall in the case of the sediment of amount, solve the problems, such as that equipment is hardened.By pre-
Heavy sewage enters mixing pit B9, is further added except hard medicament in mixing pit B9, in stirring for mixing pit mixer B8
(mixing speed R=80rpm) is mixed down, medicament and sewage is sufficiently mixed.Mixed sewage enters flocculation by baffle plate B10
Pond, adds flocculant in flocculation basin, (the mixing speed R=10~50rpm, by frequency conversion under the stirring of flocculation stirring machine 11
The control of device, finds suitable rotating speed), medicament and sewage is sufficiently mixed, finally enter sedimentation basin.
The preliminary sedimentation tank 7 set in the present invention, because the sewage ions content of high rigidity is very high, wants to reach by primary sedimentation
To except hard requirement, can not realize at all.So preliminary sedimentation tank is provided with the present invention, due to the sewage ions content of high rigidity
It is very high, substantial amounts of sediment can be formed after medicament is added, there is configurational ion during these precipitates and wrap up in band effect
Should, sediment carries substantial amounts of calcium ions and magnesium ions, reduces added amount of chemical.
In the present invention, polymeric coating layer is used in the inner surface of preliminary sedimentation tank 7, due to the sewage ions content of high rigidity
It is very high, when going hardness in water removal by precipitation, have substantial amounts of crystal structure and separate out, if pool wall will without treatment
There is hardened phenomenon, this problem is perfectly solved after using polymeric coating layer.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under enlightenment of the invention
The product of form, however, make any change in its shape or structure, it is every with skill same as the present application or close
Art scheme, all falls within protection scope of the present invention.
