The processing method of the TNT production generation waste water that the present invention is introduced includes acid waste water and alkaline waste water mixing, separation of solid and liquid, CO2The operations such as pressurization aluminum reduction, anaerobism, the treatment of aerobic and biological filtering tower combined working, the waste water after treatment can stably reaching standard discharge.
Description
Technical field
A kind of processing method of the waste water produced the present invention relates to TNT productions.
Background technology
TNT is a kind of explosive, is dual-use product.The organic waste water pollutant COD concentration that its production is produced is high, into
Divide complexity, intractability is big.If the waste water is not processed is directly discharged into environment, severe contamination will be caused to environment.TNT productions are produced
Two kinds of waste water, one kind is acid waste water, and another kind is alkaline waste water.The processing method of current acid waste water is mainly biological place
Reason.Due to containing nitrobenzene compounds in waste water, the toxicity to microorganism is very big, influences biological treatment effect, and waste water is difficult to
Stably reaching standard is discharged.The processing method of current alkaline waste water is mainly burning method, due to containing a large amount of nitrobenzenes in waste water
Compound, produces a large amount of NO during burningx, severe contamination atmospheric environment.Exploitation secondary pollution is small, the TNT lifes of energy stably reaching standard discharge
The processing method for producing waste water has larger practical value.
The content of the invention
For the problem of current TNT production wastewater treatments method, the purpose of the present invention is that searching secondary pollution is small, can stablize
The TNT of qualified discharge produces the processing method of waste water, it is characterised in that the acid waste water and alkaline waste water for producing TNT productions are mixed
Close, mixed waste water enters sedimentation basin, and sedimentation basin has regulatory function concurrently.Sedimentation time is 1h~3h.Irregularly from sedimentation basin
Middle extraction sludge is filtered.Filter cake makees dangerous disposition of solid waste.Filtrate returns to sedimentation basin.The supernatant waste water of sedimentation basin send
Enter voltage-resistant reactor, cleaning aluminium powder is added into reactor, and be passed through industrial CO2Reacted, the granularity of aluminium powder is less than 180 mesh,
Every liter of waste water adds aluminium powder 15g~40g, and the stirring reaction time is 2h~4h, and reaction temperature is 25 DEG C~60 DEG C, CO2Pressure
It is 0.3MPa~1.0MPa.Reacted waste water carries out solid-liquor separation, the aluminium powder Returning reactor isolated.After solid-liquor separation
Waste water milk of lime or other alkaline matters adjust its pH value to 7.0~8.5, and 1h~3h is precipitated subsequently into sedimentation basin, indefinite
Phase extracts sludge out from sedimentation basin and is filtered, and filter cake makees dangerous disposition of solid waste, and filtrate returns to sedimentation basin.Sedimentation basin
Supernatant waste water send anaerobic reactor.Waste water stops 24h~120h in anaerobic reactor, and anaerobism temperature is 25 DEG C~55 DEG C.Anaerobism
Into the treatment of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 6h~16h to waste water afterwards.Waste water after Aerobic Process for Treatment enters precipitation
1h~3h is precipitated in pond, is irregularly extracted sludge out from sedimentation basin and is filtered, and filter cake makees dangerous disposition of solid waste, and filtrate is returned
Return Aerobic Pond.The supernatant waste water of sedimentation basin send multi-layer biological filter tower to process.The filler of biological filtering tower combined working be activated carbon or porous ceramic grain,
It is 1.0m~2.0m per thickness degree, gross thickness is 2m~6m.The dominant bacteria of biological filtering tower combined working is the red false unit cell in photosynthetic bacteria
Bacterium（Rhodopseudomonas）.The hydraulic load of biological filtering tower combined working is 30 m3/m2.d~90m3/m2.d.The water outlet of biological filtering tower combined working
Qualified discharge or reuse.
The object of the present invention is achieved like this, after the acid waste water and alkaline waste water that TNT productions are produced mix, waste water meeting
Generation acid precipitation reaction.The solid matter contained in itself in the sediment and waste water that are produced in order to avoid acid precipitation reaction is to aluminum reduction
Have a negative impact, be also beneficial to unreacted aluminium powder and recycle, therefore separation of solid and liquid is carried out to it.Waste water enters aluminium powder also
After former reactor, the strong reduction that the larger molecular organicses in waste water, particularly nitrobenzene matters are produced by aluminum reduction from
Destroyed by the effect of base, substantially reduce toxicity of the waste water to microorganism, be that subsequent biochemical treatment creates favorable conditions.It is passed through pressure
Power CO2Purpose be maintain the suitable pH value of aluminum reduction（2.0~5.0）, waste water milk of lime or other alkalescence after reduction
Material adjusts its pH value, to meet the requirement of follow-up anaerobic and aerobic process.Through the waste water of aforementioned processing in anaerobic processes, lead to
The effect of microorganism is crossed, larger molecular organicses further become small organic molecule, be that more favourable bar is created in subsequent bio oxidation
Part.Processed by biological oxidation, remaining most of organic matters are removed, while the pollutant such as removing to denitrogenate.Waste water is finally entered
Activated carbon or porous ceramic grain biological filtering tower combined working, in the presence of microorganism, particularly red pseudomonas, further organics removal and
The pollutants such as nitrogen, it is ensured that the waste water stably reaching standard discharge after treatment.
Relative to existing method, the present invention destroys nitrobenzene matters, greatly reduces waste water to micro- using aluminum reduction
Biological toxicity, and greatly improve the biodegradability energy of waste water；Relative to now widely used destruction nitrobenzene matters
Method（Iron-carbon micro-electrolysis, metal powder reduction, Fenton methods etc.）, outstanding advantages of the invention are to use CO2Instead of extensive at present
The sulfuric acid for using makees acidulant, does not introduce SO4 2-Ion, largely reducing generation H2The material base of S（TNT production waste water contains
S）, so as to significantly reduce H2The pollution of S, while also mitigating SO4 2-Suppression to microorganism during anaerobic and aerobic is made
With greatly improving the efficiency of biological treatment, it is ensured that the waste water energy stably reaching standard discharge after treatment；Boiler is all had in TNT factories,
The CO that fuel combustion is produced2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission, with bright
Aobvious economic benefit and environmental benefit.
