Description
Technical field
The present invention relates to belong to technical field of waste water processing, particularly to a kind of high salinity waste water processing means and waste water thereof
Processing method.
Background technology
Organic high-salinity wastewater refers to the useless of the total dissolved solid thing containing Organic substance and at least 3.5% (mass fraction)
Water, this waste water is in addition to containing organic pollution, possibly together with substantial amounts of inorganic salt.High-salt wastewater has inhibitory action to biochemical treatment,
Showing as osmotic pressure high, microbial cell dehydration causes cellular plasm to separate, and microbial metabolism enzymatic activity is obstructed, and causes biology
Increaseing slowly, yield coefficient is low.As NaCl concentration ＞ 1wt%, it is possible to make the breathing rate of microorganism reduce, work as NaCl concentration
During ＞ 2wt%, growth of microorganism can be caused to be suppressed, BOD (the Biochemical Oxygen Demand of activated sludge process
Write a Chinese character in simplified form, refer to Biochemical oxygen demand or bod, represent a comprehensive finger of the aerobic pollution matter content such as Organic substance in water
Mark) clearance reduction, the flocculability in mud degenerates simultaneously, water outlet SS (Suspended solid refers to solid suspension concentration)
Raise.
The source of high salinity waste water mainly includes that sea water is directly used in commercial production and domestic water, as wide in industrial sea water
The general high salinity waste water of discharge in boiler cooling water, and commercial production, as marine products process, pickle, pharmacy, chemical industry, print
The industries such as dye.China's high-salt wastewater generation amount accounts for the 5% of waste water total amount, and still increases with the speed of 2% every year, these high salt,
High organic wastewater, if the most appropriately processed, it will ecological environment is caused high risks.
Summary of the invention
In view of this, one of the object of the invention is to provide a kind of high salinity waste water processing means.At this high salinity waste water
Reason device solves the problem that in waste water, organic concentration is high, biodegradability is low and water outlet is the most up to standard.
The present invention is by the following technical solutions:
A kind of high salinity waste water processing means, including the first pH regulator pond being sequentially connected with by pipeline, iron-carbon micro-electrolysis
Pond, Fenton's reaction pond, the second pH regulator pond, coagulating basin, flocculation basin, physico-chemical precipitation pond, the first hydrolysis acidification pool, the first anoxia
Pond, the first Aerobic Pond and the first second pond.
In iron-carbon micro-electrolysis pond, iron filings and ferrum carbon dust composition corrosion cell, electrode reaction generates substantial amounts of Fe2+And atom
H has high chemism, can change many organic structures and characteristic in waste water, make Organic substance generation chain rupture, and open loop etc. is made
With, the Fe that reaction generates2+Participate in the redox reaction in solution, generate Fe3+, reaction later stage solution ph raises, Fe3+By
Gradually hydrolysis generates the Fe (OH) that the degree of polymerization is big3Colloid flocculates, and can effectively adsorb, pollutant in coagulation water, thus strengthens
Clean-up effect to waste water, so Fe-C Micro Electrolysis Method can effectively remove the pollutant in waste water, cuts down organic toxicity, carries
The biodegradability of high waste water.
Fenton's reaction has good removal efficiency for different waste water to COD, and have may be up to 60%～70%, utilize
The hydrogen produced or hydroxyl radical free radical combine ferrous ion, remove the Organic substance of difficult for biological degradation, improve the biodegradability of waste water.
Hydrolysis acidification pool, is opened the C-C of organic molecule by the acid-producing bacteria in activated sludge, is hydrolyzed to by long-chain short
Chain, side chain or ring assembling structure become straight chain, reduce the toxicity of waste water, improve wastewater biodegradability.In period reply hydrolysis acidification pool
Activated sludge is tamed, and makes acid-producing bacteria adapt to the environment of high-salt wastewater, keeps activity.
Adding activated carbon in Aerobic Pond, the specific surface area that activated carbon is huge, high adsorption capacity, surface starts to breed micro-life
Thing, forms biomembrane, and oxygen and Organic substance is concentrated in around, increase time of contact, and adsorbed COD composition decomposes therewith,
And aging biomembrane is come off by water impact, cause regenerating active carbon, can continuous and effective play a role, regeneration rate be 70%～
90%.After adding activated carbon, the tolerance of salinity of system is obviously improved, and improves anti-shock loading, strengthens Nitrification, and has preferably
Ground decolouring, deodorization, eliminate the advantages such as foam.
In second pond, owing to sewage being mixed with activated carbon, actually play the heavy effect that helps, improve dehydrating effect, live
Property the adsorptivity of charcoal and higher suspended make COD, the BOD removal capacity of activated sludge process improve 30%-40%.
The high salinity waste water processing means of the present invention solves following problem:
(1) poor processing effect: in traditional activated sludge process, salinity below 1wt% to be maintained at, excessive concentration, can make
Microbial activity reduces, and the growth to microorganism produces inhibitory action, reduces organic removal rate, and the waste water of the present invention is through thing
After change processes, organic concentration reduces, and subsequent biochemical load is reduced, it is ensured that standard water discharge；
(2) difficulty is run big: in running, the unexpected change of salt and organic concentration, on the impact of microorganism very
Greatly, can directly destroy properly functioning, zoogloea disintegrates, Mud up-floating, and water outlet COD raises, and what biochemistry part of the present invention used
Technique either salt tolerance, mithridatism, capacity of resisting impact load all increases significantly, and salinity can reach 3.5wt%；
(3) processing cost is high: according to ion exchange, membrane separation process or heating vaporization, effluent quality can be relatively good,
But relate to ion exchange resin regeneration, Pore Blocking or the problem such as power consumption is high, processing cost can be caused high, the present invention's
The features such as wastewater treatment equipment has applied range, strong adaptability, low cost.
For organic high-salinity wastewater, single materialization or biochemical process are difficult to obtain preferable treatment effect, high salt of the present invention
Degree wastewater treatment equipment uses Physiochemical and biochemical to combine, and materializing strategy, by Fenton's reaction and flocks, flocculation sediment, can reduce
The organic concentration of waste water and toxicity, reduce the load that subsequent biochemical processes；Biochemical treatment then uses activated carbon-activated sludge
Method, activated carbon carries out the process of " adsorb-degrade-regenerate-adsorbing again ", high treating effect in system, and anti-shock loading is strong, fortune
Row expense is low, improves the biodegradability of waste water, and most COD major part is degraded.
Wherein, described first pH regulator pond previously by pipeline connect have collecting-tank, described collecting-tank by elevator pump with
Described first pH regulator pond connects.
Wherein, the bottom in described physico-chemical precipitation pond is provided with sludge pump, and described mud delivery side of pump connects sludge-tank, institute
Stating and be provided with homogeneous pond between physico-chemical precipitation pond and described first hydrolysis acidification pool, described homogeneous pond is connected with sanitary sewage pond.
Wherein, be sequentially provided with after described first second pond the second hydrolysis acidification pool, the second anoxic pond, the second Aerobic Pond,
