Description
Technical field
The present invention relates to a kind of purifying treatment method of high salinity waste water, belong to the industrial waste water purifying processing technology field.
Background technology
In field of environment protection, people utilize reverse osmosis technology to handle brine waste at present.Reverse osmosis technology is to use a kind of film that can stand higher hydraulic pressure intensity, and it can only allow water molecules see through, and foreign ion sees through in the pending water but can not allow, thereby clear water is separated from brackish water.Used film is a kind of semi-permeable membranes in the reverse osmosis technology, and the surface of this film has optionally adsorptive power, can adsorbed water molecule and repel the particulate of salt, formation one pure water layer on the interface of film and solution.Under the effect of reverse osmosis pressure, the pure water in this water layer oozes out with regard to constantly seeing through semi-permeable membranes.Therefore, when adopting the reverse osmosis method treating water, the film surface-moisture constantly permeates, and the salt particle in the water and other materials then are trapped in and make salt concn rising in the original solution in the original water, can produce very high concentration gradient when serious.Simultaneously in order to ensure insoluble salt in the water not at the film surface scale and hinder the growth of step microbial, can in solution, add materials such as sodium pyrosulfate and phosphoric acid salt.Through producing a certain amount of high salinity waste water after the reverse-osmosis treated.Ionic species in the modal high salinity waste water has Na
+, Mg
2+, Ca
2+, SO
4 2-, PO
4 2-And Cl
-Deng and trace heavy metal element.The pH value of the high salinity waste water that general reverse osmosis method process produces is 5～7.5, and hardness is 1000～1500mg/L, and basicity is 1000～1500mg/L, and COD is 100～200mg/L, and total solids is 2000～40000mg/L, and electric conductivity is 70～150mV.Organic content is low in this class high salinity waste water, salinity is high, hardness is big, ionic species is many, biodegradability is poor.Along with reverse osmosis technology widespread use in water treatment, the high-salt wastewater of discharging after the reverse-osmosis treated have a better treatment process, but need a kind of easily, efficiently, the treatment process of the high salinity waste water of the reuse of compliance with environmental protection requirements.
The treatment process of existing high salinity waste water has two classes basically: the high salinity waste water of discharging in the reverse-osmosis treated device of (1) boiler of power plant water design, the general flyash that all is used for washing electric dust collector; This method can not fundamentally be handled reverse osmosis process waste water, rises in case the amount of high salinity waste water increases severely, and this method just can not be handled.(2) high salinity waste water that produces after the sea water desaltination generally directly flows back in the seawater.Have now found that because the row of returning of high salinity waste water causes local marine site salinity to rise, the original biotic population in this area is damaged.
Summary of the invention
But the treatment process that the purpose of this invention is to provide the high salinity waste water of a kind of simple and easy, efficient, compliance with environmental protection requirements, water reuse.
The treatment process of a kind of high salinity waste water of the present invention is characterized in that having following treating processes and step:
A. in high salinity waste water, add organic substance,, and mix as organic waste water or ethylenediamine tetraacetic acid (EDTA) or phenylglycine or anthraquinone as the water quality regulation material;
B. will carry out irradiation by the electron beam that rumbatron produces through the high salinity waste water of water quality regulation; The energy of accelerator accelerated electron is 0.8MeV, and electronic beam current intensity is 10mA, and the treatment time is 20～30 seconds; Carry out aeration simultaneously, high salinity waste water is contacted fully with electron beam, to reach metal ion reduction and the oxidized purpose of organism;
C. with the certain precipitation of the process of the waste water after the radiation treatment; Throw out deals with in addition; Processed waste water salinity clearance at this moment can reach more than 99%, reaches discharging standards;
D. the waste water after precipitation process carries out advanced treatment through advanced treatment apparatus again; Be provided with activated carbon adsorption layer and reverse osmosis membrane in the advanced treatment apparatus, make waste water further obtain handling, finally reach the waste water recycling standard and become used water.
High-salinity waste water treatment method of the present invention mainly is to adopt the electron beam irradiation treatment process, and the electron beam that rumbatron produces is a kind of high-energy electromagnetic radiation, and the energy by controlling electron beam can make the penetration power of electronics be adapted to service requirements among the present invention.Ionizing rays mainly is promptly to produce hydroxyl radical free radical OH, hydroperoxyl radical H and hydrated electron e by water decomposition by indirect effect
-agWith organic substance in the high salinity waste water and metal ion reaction and work, that is to say and impel metal ion reduction and organic substance oxidation in the high salinity waste water.
Under radiation effect, produce the free radical activity particle in the water, active particle and organism reaction make it progressively to be decomposed into water molecules, carbonic acid gas and some organic water moleculess; Active particle reducing metal ion on the other hand makes it combine with macromolecular substance in the water, is precipitated out from water.
Add the organic substance as the water quality regulation material in the high salinity waste water, its effect is to make metal ion and organism that integration easily take place, thereby it is precipitated out from water.
The inventive method technology is simple, and is easy to operate; Irradiance method labile organic compound and reducing metal ion; The inventive method can make the salt clearance of highrank fuel salinity water reach more than 99%, can make water reach reuse standard.
