Abstract
The invention discloses a kind of waste water treatment process, which is characterized in that includes the following steps：The organic matter in waste water is adsorbed by magnetic ion exchange resin；Waste water after being adsorbed to magnetic ion exchange resin carries out hyperfiltration treatment；Reverse osmosis unit carries out reverse-osmosis treated to ultrafiltration permeate；Suspension processing is carried out by the way that remover is added, the remover forms with the waste water reaction after reverse-osmosis treated and neutralizes water；Precipitation process is carried out, makes the suspended matter precipitation in the neutralization water, forms separation water；The sediment in the separation water is removed, processing water is formed.The present invention provides a kind of waste water treatment process, the organic matter that can be effectively removed in waste water and reduce COD concentration, to improve the yield of waste water recycling, and reverse osmosis concentrated water is made to reach discharge standard.
Description
Technical field
The present invention relates to field of waste water treatment more particularly to a kind of waste water treatment process.
Background technology
In order to further decrease the organic matter in reverse osmosis concentrated water, in order to which the COD for further decreasing reverse osmosis concentrated water is dense
Degree, to reach discharge standard, someone uses ozonation technology, and the carbochain of organic matter is destroyed using the strong oxidizing property of ozone, from
And achieve the purpose that decomposing organic matter.However, using ozone oxidation, there are the following problems：1) ozone oxidation is only macromolecular
Organic matter becomes small organic molecule, also needs to further handle after oxidation；2) when the content of organics in water is extremely low,
The effect of ozone oxidation is preferable, however due to containing a large amount of readily oxidizable substance in the complicated component of water quality, especially industrial wastewater
Matter, such as ammonia nitrogen etc., when ozone to be added in this water body, these substances consume rapidly a large amount of ozone, and smelly
Concentration of the oxygen in gas and water is limited, causes ozone ineffective in practical applications, influences the recovery utilization rate of waste water；3)
The preparation efficiency of ozone is low, and when the ozone amount of needs is big, equipment and operating cost are expensive；4) ozone generating apparatus and technique
It is easy to happen leakage in actual operation, although using technology for absorbing tail gas mostly, still to the health structure of operator
At threat, therefore, application is restricted.
Invention content
The object of the present invention is to provide a kind of waste water treatment process, the organic matter that can be effectively removed in waste water and
COD concentration is reduced, to improve the yield of waste water recycling, and reverse osmosis concentrated water is made to reach discharge standard.
Technical scheme of the present invention：A kind of waste water treatment process, which is characterized in that include the following steps：
The organic matter in waste water is adsorbed by magnetic ion exchange resin；
Waste water after being adsorbed to magnetic ion exchange resin carries out hyperfiltration treatment；
Reverse osmosis unit carries out reverse-osmosis treated to ultrafiltration permeate；
Suspension processing is carried out by the way that remover is added, the remover forms with the waste water reaction after reverse-osmosis treated and neutralizes water；
Precipitation process is carried out, makes the suspended matter precipitation in the neutralization water, forms separation water；
The sediment in the separation water is removed, processing water is formed.
A kind of waste water treatment process above-mentioned, which is characterized in that a concentration of 100- of the magnetic ion exchange resin
200ml/L。

12 minutes.
A kind of waste water treatment process above-mentioned, which is characterized in that the remover is aqueous slkali.
Beneficial effects of the present invention：The organic matter that can be effectively removed in waste water and reduce COD concentration, it is useless to improve
The yield of water reuse, and reverse osmosis concentrated water is made to reach discharge standard.
Specific implementation mode
The present invention is further illustrated for following example, but is not intended as the foundation limited the present invention.
Embodiment：A kind of waste water treatment process, includes the following steps：
The organic matter in waste water is adsorbed by magnetic ion exchange resin；
Waste water after being adsorbed to magnetic ion exchange resin carries out hyperfiltration treatment；
