Abstract
The present invention relates to a kind of methods of Treated sewage reusing, include the following steps：（1）Depickling waste water is put into depickling wastewater disposal basin；（2）Depickling waste water in depickling wastewater disposal basin is put into sewage plant concentration basin, calcium hydroxide is then put into and is stirred, acid-base value and salinity are adjusted；（3）By step（2）Depickling waste water after middle adjusting send to inspection center and detects salinity and basicity, is qualification when pH >=10, salinity ＜ 1.5%；（4）It will be through step（3）The qualified depickling waste water of detection is sent into press filtration in filter press so that water and mud separation；（5）Step（4）Water after middle separation is sent into chilling tower and is used, or is sent into depickling wastewater disposal basin and continues reuse.The present invention is easy to operate, can be removed most of salinity in waste water and make waste water that alkalinity be presented, and reaches depickling water and uses standard.And the reuse of depickling waste water greatly reduces the disposition pressure of waste water, has saved process water, has reduced cost.
Description
Technical field
The present invention relates to a kind of methods of Treated sewage reusing, belong to the technical field of depickling waste water recycling.
Background technology
Flue gas will will produce a large amount of sour gas during washing cigarette, and depickling direct discharging of waste water amount is very big,
Water quality highly acid, and it is dissolved with a large amount of salinity, sewage disposal device is damaged larger.It therefore, must be right before sewage disposal
Depickling waste water carries out Treatment for Reuse, is removed to the salinity in waste water and makes waste water that alkalinity be presented, to reach making for depickling water
Use standard.Thus the present invention generates.
Invention content
For the above-mentioned technical problem of the prior art, the object of the present invention is to provide a kind of method of Treated sewage reusing, the party
Method is easy to operate, can be removed most of salinity in waste water and make waste water that alkalinity be presented, and reaches depickling water and uses standard.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions：
A kind of method of Treated sewage reusing, includes the following steps：
（1）Depickling waste water is put into depickling wastewater disposal basin；
（2）Depickling waste water in depickling wastewater disposal basin is put into sewage plant concentration basin, calcium hydroxide is then put into and is stirred, is adjusted
Acid-base value and salinity；
（3）By step（2）Depickling waste water after middle adjusting send to inspection center and detects salinity and basicity, pH >=10, salinity ＜
It is qualification when 1.5%；
（4）It will be through step（3）The qualified depickling waste water of detection is sent into press filtration in filter press so that water and mud separation；
（5）Step（4）Water after middle separation is sent into chilling tower and is used, or is sent into depickling wastewater disposal basin and continues reuse.
The input amount of the calcium hydroxide is fluorinion concentration the * 20*74/36/1000, unit kg in depickling waste water.
Beneficial effects of the present invention are as follows：
The method of Treated sewage reusing of the present invention, it is easy to operate, most of salinity in waste water can be removed and waste water is made to present
Alkalinity reaches depickling water and uses standard.And the reuse of depickling waste water greatly reduces the disposition pressure of waste water, has saved technique use
Water reduces cost.
Specific implementation mode
With reference to specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to
This.
Embodiment 1
The method of 1 Treated sewage reusing of the present embodiment, includes the following steps：
（1）Depickling waste water is put into depickling wastewater disposal basin；
（2）Depickling waste water in depickling wastewater disposal basin is put into sewage plant concentration basin, calcium hydroxide is then put into and is stirred, is adjusted
Acid-base value and salinity；The input amount of calcium hydroxide is fluorinion concentration the * 20*74/36/1000, unit kg in depickling waste water.
（3）By step（2）Depickling waste water after middle adjusting send to inspection center and detects salinity and basicity, pH >=10, salinity
It is qualification when ＜ 1.5%；
（4）It will be through step（3）The qualified depickling waste water of detection is sent into press filtration in filter press so that water and mud separation；
（5）Step（4）Water after middle separation is sent into chilling tower and is used, or is sent into depickling wastewater disposal basin and continues reuse.
The present invention is easy to operate, can be removed most of salinity in waste water and make waste water that alkalinity be presented, reach de-
Sour water uses standard.And the reuse of depickling waste water greatly reduces the disposition pressure of waste water, has saved process water, has reduced into
This.
Above-described embodiment is only used for illustrating the inventive concept of the present invention, rather than the restriction to rights protection of the present invention,
All changes for carrying out unsubstantiality to the present invention using this design, should all fall into protection scope of the present invention.
