Description
Technical field
The present invention relates to field of waste water treatment, and in particular to a kind of waste water treatment system.
Background technique
According to technique applied by existing wastewater zero discharge engineering, the engineer application of wastewater zero discharge, pre- to locate in recent years
Reason and the technique of film concentration become technique most widely used in recent years.It is dense that reverse osmosis technology is undoubtedly most economical efficient film at present
Contracting mode, and the key of reverse osmosis desalinization system design is pretreated selection.Using feed water by reverse osmosis water quality.Due to waste water
Hardness is high, silicone content is high, therefore for this project reverse osmosis membrane dirt must be taken into consideration and blocks up risk and greatly increase.Since system is intake
Water source is more, and water quality is complicated, and temporarily without specific inorganic phase reverse osmosis concentrated water water quality, and caustic soda workshop salt dissolving is to water inlet
COD require it is very tight, salt dissolving device is particularly significant as the production master device of owner.
However wastewater treatment is substantially carried out in a manner of physics for the processing of waste water at present, but for waste water
Processing is not thorough enough, will cause the waste of water resource, and not can be carried out concentration for waste water, removes firmly, except the processing such as COD.
Summary of the invention
The object of the present invention is to provide a kind of waste water treatment system, have waste water can be concentrated, except it is hard, remove
The advantages of processing such as COD.
Above-mentioned technical purpose of the invention has the technical scheme that

It is respectively put into PAM, PAC, caustic soda, soda ash, magnesia, for the processing to waste water, active carbon mistake is connected in efficient sedimentation tank
Filter, active carbon filter are connect with ozone contact tank, for the double medium filtration to waste water.The side of active carbon filter and tune
Pond connection is saved, the other side of active carbon filter is connected with backwashing pump, will be in device for drawing water when active carbon filter blocks
Portion is filled.
By using above-mentioned technical proposal, PAM, PAC, caustic soda, soda ash, the magnesia being put into efficient sedimentation tank can be incited somebody to action
Impurity in waste water precipitate and except that firmly, can be removed to the COD in waste water using active carbon filter, is convenient for people
Operation and use.Using turning one's coat, pump can be when active carbon filter be blocked, and water suction enters in active carbon filter, makes
Active carbon filter is along logical.
Further setting: PAM has been put into dewaterer.Ozone is put into ozone contact tank, for passing through ozone oxidation
COD is removed to waste water.
By using above-mentioned technical proposal, effectively waste water can be carried out dehydrating using PAM, convenient for operation and
It uses.Effectively the COD in waste water can be removed by the ozone in ozone contact tank.
Further setting: water tank is divided into the first ultrafiltration reaction water tank, the second ultrafiltration reaction water tank and ultrafiltration cyclic water tank, the
One ultrafiltration is reacted water tank, the second ultrafiltration reaction water tank and ultrafiltration cyclic water tank and is connected respectively by pipeline, the first ultrafiltration reaction water
It is respectively put into caustic soda and soda ash in case, the second ultrafiltration reaction water tank, for removing the hardness of waste water, ultrafiltration cyclic water tank and DTRO
Concentration systems connection, for internal waste water to be carried out circular treatment.
By using above-mentioned technical proposal, can continue to pair using the first ultrafiltration reaction water tank, the second ultrafiltration reaction water tank
Neutralization is adjusted in waste water, when waste water alkalinity is excessively high, is put into acidity in the first ultrafiltration reaction water tank, excessively high in waste water acidity
When, it is put into alkalinity in the second ultrafiltration reaction water tank, the reconciliation to waste water is realized with this.Using ultrafiltration cyclic water tank to inside
Waste water carries out circular treatment and filtering.
Further setting: tubular type ultrafiltration system is loop ultrafiltration film, for handling highly filled liquid.DTRO concentration
System is disc tube reverse osmosis (dt-ro) membrane module, and the side of DTRO concentration systems is connected with water supply tank.Advanced oxidation system is ozone oxygen
Change, for being removed again to the COD inside waste water.Dense section pond is divided into qualified concentrated water pond and unqualified concentrated water pond, for pair
The storage of water.
By using above-mentioned technical proposal, highly filled liquid can handle using loop ultrafiltration film, simultaneously because
The big stream turbulent flow of loop ultrafiltration film surface and cross-flow reduce pollution of the pollutant to film surface.Using higher oxide be for
The multiple removal to COD in water.Qualified concentrated water pond stores the water handled with unqualified concentrated water pond.It utilizes
DTRO concentration systems efficiently avoid film blocking and concentration polarization phenomenon, successfully extend the service life of diaphragm.
In conclusion the invention has the following advantages: people can be multiple the COD in water is removed, prevent
Sealing resource it is unclean, while waste water can also be concentrated, except hard, it is convenient for people to use.Using this system to useless
Water is handled, additionally it is possible to save the waste of water resource.
