Abstract
The invention relates to a sewage treating method, in particular to a ceramic sewage treating method. The ceramic sewage treating method comprises the following steps: adding an Al2(SO4)3 solution in sewage; and enabling the pH value of the sewage to reach 6.0-6.5. The concentration of the Al2(SO4)3 solution is 25-30wt%; and the use amount of the Al2(SO4)3 solution is as follows: 0.3-0.8 L of the Al2(SO4)3 solution is added in every ton of the sewage. The method is simple and economic, on the promise of guaranteeing quality of sewage treatment and atmospheric emission, the sewage is modified secondarily, and therefore, negative effects to properties of ceramic slurry are eliminated.
Description
Technical field
The present invention relates to sewage water treatment method, specifically a kind of pottery sewage water treatment method.
Background technology
Ceramic tile production enterprise consumes substantial amounts of industry water during producing, and the industry simultaneously producing almost equivalent is dirty
Water, these sewage, are to solidify suspension containing substantial amounts of mud sand material, glaze, chemical industry material, grinding tool particle etc. when at the beginning.They
So that solidfied material is separated with water after specific solid-liquor separation purified treatment program, and this water after separating is just
Can be re-used for, among enterprise's production, so again and again water being reused, wherein, for carcass raw material goal
Grind the amount that adds water just constitute about whole effluent cycle again consumption 80% about.
But in actual production, each ceramic tile production enterprise all can run into such a stubborn problem：Use sewage
Mud property afterwards is substantially deteriorated, and is exactly below the present inventor's comparing result aborning：
With this return sewage add ball mill after, grind come mud serious there occurs thixotroping, the lighter also can go out
Show the problem that mud speed rate is slack-off, mobility is deteriorated, the fineness of mud becomes big simultaneously, and the mud for reaching same fineness must not
The not run time of director's ball mill, for solving the problems, such as that grinding efficiency declines, mud property is deteriorated, has only and takes increasing mud
The method that the consumption of degumming agent, water reducer etc., increasing mud moisture content, prolongation Ball-milling Time etc. increase energy consumption increase cost goes to solve
Certainly.
Content of the invention
It is an object of the invention to provide a kind of pottery sewage water treatment method, to solve the above problems.
For reaching above-mentioned purpose, the present invention employs the following technical solutions：
A kind of pottery sewage water treatment method, adds Al in sewage2(SO4)3Solution, makes pH value of sewage water reach 6.0 ~ 6.5.
Further, described Al2(SO4)3The concentration of solution is 25 ~ 30wt%.
Further, described Al2(SO4)3The consumption of solution is that sewage per ton adds 0.3 ~ 0.8L Al2(SO4)3Solution.
Further, the method comprises the following steps：
S1, individually mark several ponds in sewage disposal system as ball milling water pool specialized, sewage passes through a dedicated water
Canal is to this pond water filling；
S2, described special water channel installed above carry mixer water tank, the lower half of water tank install a tap go out
The mouth of a river；
S3, in water tank add Al2(SO4)3And it is melted into the aqueous solution, concentration is in 25～30wt%；
S4, sewage, in ball milling special basin the injecting process, are opened the tap below water tank, are equably dripped to the sewage flowing through
Plus Al2(SO4)3The aqueous solution, additional proportion is that sewage per ton adds 0.3 ~ 0.8L Al2(SO4)3Solution.
It is known that during the dirty water decontamination handles to Production of Ceramics enterprise, for making solidification suspension rapid subsidence,
Need to add propylene oxide polyethylene aluminium, the polypropylene acid auxiliary compounds such as ammonium and quick lime, make the pH value of water reach more than 7.5, so
Be conducive to the purified treatment to airborne release simultaneously.But the present inventor's research shows, the sewage of exactly this pH value >=7.5, but
Make ceramic mud degradation, lead to enterprise's production capacity to increase further.
For this problem, grope and research through long-term, the invention provides a not only simple but also very economic side
Method, can realize twice-modified to sewage quality, thus eliminating on the premise of ensureing sewage disposal and airborne release quality
Its negative effect to ceramic mud performance.Al is added in sewage2(SO4)3Solution, Al2(SO4)3Water quality is made to be become by alkalescent
Faintly acid, its mechanism is Al2(SO4)3Water hydrolyzes, creates substantial amounts of H+Ion：Al2(SO4)3+6H2O=6H++
3SO4 -2+2Al(HO)3（Precipitation）.
Specific embodiment
With reference to specific embodiment, the present invention is described further.

S1, individually mark several ponds in original sewage disposal system as ball milling water pool specialized, sewage passes through one
Special water channel is to this pond water filling；
S2, the water tank of the mixer that is of moderate size, carries in this special water channel installed above, install a water in the lower half of water tank
Faucet water outlet opening；
S3, in water tank add Al2(SO4)3And it is melted into the aqueous solution, concentration is in 27wt%；
S4, sewage, in ball milling special basin the injecting process, are opened the tap below water tank, are equably dripped to the sewage flowing through
Plus Al2(SO4)3The aqueous solution, additional proportion is that sewage per ton adds 0.5L Al2(SO4)3Solution, make pH value of sewage water reach 6.0 ~
6.5.
This treated sewage is used for the production of ball-milling ceramic mud, and compares with new water for industrial use, as following table institute
