Description
Technical field
The invention belongs to field of industrial waste water treatment, be specifically related to a kind of processing method containing acid salt-containing organic wastewater.
Background technology
In the industry, the method processing general employing biochemical treatment containing acid salt-containing organic wastewater, the salt of industrial wastewater is dense
Degree height can affect the effect of biochemical treatment, prior art literature: " Techniques and Equipment for Environmental Pollution Control " periodical in 2005, one
The literature research of entitled " high salt concentration influence research to biochemical treatment of industrial wastewater " high salt concentration industrial wastewater is to life
The impact that change processes, when salinity height, sludge activity is suppressed, and COD clearance declines, and reduces the treatment effeciency of waste water.And
And the equipment investment of biochemical treatment is big, the treatment cost of waste water is high.
Summary of the invention
Goal of the invention: the invention aims to solve above-mentioned technical problem, it is provided that a kind of low cost, easy containing acid
The processing method of salt-containing organic wastewater.
Technical scheme: a kind of processing method containing acid salt-containing organic wastewater of the present invention, comprises the following steps:
A the pH value of () regulation waste water is to 8-9；
B step (a) is processed the oil proceeded in oil interceptor removal waste water after gained waste water enters depositing reservoir process and divides by ()；
C the waste water of gained after step (b) process is processed through pressure filter and is separated by the solid particle in waste water by ()；
D step (c) gained waste water is passed through electrodialysis plant by (), obtain the concentration containing organic desalination water and saliferous
Water；
E (), is carried out discharging containing Organic substance desalination water and the situation of saliferous condensed water according to step (d) gained, middle water
Reuse or after-treatment.
Preferably, in described step (a), the pH value sodium hydroxide of waste water regulates.
Preferably, the described electrodialysis plant of described step (c) includes cavity block and the anode membrane of semi-transparent performance, described cavity block and institute
Stating anode membrane alternately to install, under electric field action, cation is become with the anion binding oozed in adjacent anode membrane by cavity block
Salt, and part water discharges (title condensed water) from concentrated phase room, and other composition non-ionic is worn between film along with major part water
Thoroughly discharge (title desalination water), thus by complicated component containing Organic substance, the water of inorganic matter, be separated into main band organic light
Change water and the condensed water of main band inorganic matter.
After electrodialysis process waste water, the disposition about desalination water and condensed water is divided into following several, as shown in the table.
(, with 10 tons as boundary, electrolyte concentration is with 1g/L as boundary, and organic concentration is with 0.3g/L as boundary for wastewater treatment capacity
Limit, more than boundary value, is designated as " greatly ", less than boundary value, is designated as " little " in form in form.)
When wastewater treatment capacity is bigger, during organic concentration height, after electrodialysis process, containing in Organic substance desalination water owing to having
Machine thing content is high, and desalination water, through simple distillation or azeotropic distillation, reclaims Organic substance, and the water steamed is as Treated sewage reusing.
When wastewater treatment capacity is less, during organic concentration height, after electrodialysis process, the desalination water containing Organic substance is due to water
Measuring less, content of organics is high, uses the method for burning disposal to process.
Described Treated sewage reusing refers to that the waste water after processing uses as fresh water (FW), continues to put into identical course of reaction
In, then produce containing acid salt-containing organic wastewater, so, it is achieved that recycling of waste water.
Beneficial effect: a kind of processing method containing acid salt-containing organic wastewater of the present invention, utilizes electrolyte, non-electrolytic
Matter difference electrical property, uses electrodialysis plant, is separated with electrolyte by Organic substance, then carry out subsequent treatment.With prior art
Comparing, the method technological process that the present invention processes waste water is simple, and treatment effeciency is high, and input cost is low, as built a set of biochemical treatment
Device, invests about 1,200,000 yuan, cost for wastewater treatment per ton 80 yuan, and uses the processing method of the present invention, and built processing means is thrown
Provide 200,000 yuan, cost for wastewater treatment per ton 30 yuan.The present invention adequately achieves recycling of waste water, energy-saving and emission-reduction, is conducive to
Enterprise realizes sustainable development.
Accompanying drawing explanation
Fig. 1 is the process chart of the present invention.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
See Fig. 1
Embodiment 1
With Oleum Terebinthinae as raw material, aluminum chloride as catalyst, toluene make the reaction of polymerization terpene resin of solvent, instead
After should terminating, can produce containing toluene, hydrochloric acid, aluminium hydroxide highly acid with water decomposition aluminum chloride and after terpene resin is cleaned multiple times
Waste water, be that the most pending waste water of the sector processes a difficult problem.
Utilize the waste water treatment process of the present invention, in waste water, first add sodium hydroxide, pH is adjusted to 8-9, clarified pond
Enter oil interceptor after process, isolate the toluene of about 95%, then waste water is processed through pressure filter, separate consolidating in waste water
Body granule obtains limpid waste water about 50 tons, containing NaCl1.4g/L, containing toluene 0.086g/L, is passed into an effective filtering surface
