The high concentration technique waste water of this detailed description of the invention uses and adds pyrohydrolysis way and it is carried out dechlorination locate in advance
Reason.Most of AOX in waste water can be allowed to be converted into alcohol, aldehyde, ketone or acid etc. by hydrolysis, can improve
Its biodegradability and handlability, hydrolysis is generally carried out in the basic conditions, and heating can accelerate hydrolysis
The speed of reaction.Experiment shows, controls at pH more than 12, and temperature is between 80～90 DEG C, in this mistake
The clearance of Cheng Zhong, AOX can reach more than 70%.Still contain in the technique waste water of dechlorination pretreatment
The inorganic salts ingredients of higher concentration, inhibited to later stage biological treatment, take flash distillation desalinating process,
Concentrating spent liquor is transported outward burning disposal or carries out the recovery of salt, and the condensed laggard walking of distillation uses Zero-valent Iron
Reduction technique dechlorination, lab scale and pilot scale research show, the dechlorination rate for middle low concentration wastewater can reach 90%
Above.High concentration technique waste water access comprehensive wastewater regulating reservoir through above-mentioned dechlorination, desalting processing.
Through desalination dechlorinate after high concentration technique waste water with other in low concentration produce waste water be linked into work in the lump
Skill wastewater equalization pond carries out the regulation of the water yield and water quality.Pretreating process uses: catalysis Fe-C oxidoreduction
Coagulating sedimentation O3/H2O2 homogeneous catalytic oxidation Combined Treatment new technology.Coagulating sedimentation reaction is passed through
Colloidal substance in sedimentation waste water and part larger molecular organics, effectively reduce COD concentration, utilize simultaneously
The character that AOX dissolubility in water is the least, removes part AOX pollutant.Correlation test research shows, mixed
Retrogradation shallow lake can respectively reach 10% and 5% to the removal of the said firm's waste water COD and AOX.O3/H2O2 technique is
One in advanced oxidation processes (AOP), it is the most active that it has the following characteristics that (1) can produce
Hydroxyl radical HO, its oxidability (2.80V) is only second to fluorine (2.87V), it as reaction
Intermediate product, can induce chain reaction below；(2) HO can be without selectively dirt directly and in waste water
Dye thing reaction is degraded to carbon dioxide, water and harmless salt, will not produce secondary pollution；(3) due to it
It is a kind of physical and chemical process, it is easy to be controlled by, with satisfied process needs, it might even be possible to degraded 10-9
The micropollutants of level.The organic process of O3/H2O2 oxidative degradation is the most efficient.
After using above combined treatment process, total COD and AOX pretreating effect is made to respectively reach
20%-30% and 10%～15%.Effectively reduce in high concentration technique waste water while COD, reduce the life of waste water
Thing inhibition, improves the biodegradability of waste water, creates conditions for follow-up biochemical treatment and qualified discharge.Warp
The technique waste water crossing Chemical Pretreatment accesses comprehensive wastewater regulating reservoir, mixes with sanitary sewage, carries out General Office
Reason.
Comprehensive wastewater materialization+biochemistry+materializing strategy: 1, coagulating sedimentation pretreatment.Composite waste first through coagulation-
Precipitation pretreatment, removing the colloidal material in waste water, water-insoluble Organic substance and part can not biochemical COD.
Water outlet is from flowing into A2/O biochemical treatment system.
2, biochemical treatment.Use A2/O technique, i.e. waste water first through anaerobic treatment, subsequently into double oxygen-good
Oxygen processes.Such flow process can improve the biodegradability of Organic Pollutants in Wastewater, runs proper going back
Denitrification effect can be reached.The water outlet of A2/O pond separates in second pond, and a mud part is back to anaerobism
Pond and oxygen compatibility pool, residue biochemical sludge accesses sludge-tank.
3, secondary clarifier effluent enters reaction tank, carries out two-stage coagulation precipitation, at final deposition pool after dosing coagulation
The suspension microorganism generated in middle removal biochemical system and colloidal solid, discharge through metering well after standard water discharge.
4, for guaranteeing wastewater to reach standard, a set of catalytic ozonation processing system of final outfit, two-stage coagulation goes out
Discharge after water is oxidized.
5, biochemical excess sludge and materialized mud pump into sludge-tank and carry out natural subsidence concentration, concentrated after
Mud uses filter press filter pressing, sludge-tank supernatant and pressure filtration yielding water certainly to flow into comprehensive wastewater regulating reservoir,
Filter cake outward transport is disposed.
The above is only preferred implementation of the present utility model, it is noted that for the art
For those of ordinary skill, on the premise of without departing from this utility model principle, it is also possible to make some improvement
And retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
