Description
Technical field
The present invention relates to a kind of processing method of the waste water produced as main material production propyl-butyl total solvent with Ipomoea batatas.
Background technology
Acetone, butanol, ethanol are referred to as propyl-butyl total solvent, are medicine, agricultural chemicals, plastics, paint, national defence and light industry
Important source material, early stage mainly produces propyl-butyl total solvent by raw material of oil.Produce the third fourth using biomass ferment in recent years always molten
Agent has become a kind of development trend.Ipomoea batatas is one of primary raw material of production propyl-butyl total solvent, and it produces the organic wastewater for producing
Middle pollutant COD concentration is high, and complicated component, intractability is big.If the waste water is not processed is directly discharged into environment, environment will be caused
Severe contamination.The processing method for producing the waste water that propyl-butyl total solvent is produced currently with Ipomoea batatas is mainly biological treatment.Due to
Contain persistence organic pollutant in the waste water（Containing phenyl ring and（Or）Heterocycle organic matter）, it is main former especially with fresh sweet potatoes
During material, the concentration of persistence organic pollutant is higher, thereby results in the Biochemical method waste water it is difficult to stably reaching standard discharge.Exploitation
The processing method of the waste water that the utilization Ipomoea batatas production propyl-butyl total solvent of energy stably reaching standard discharge is produced has larger practical value.
The content of the invention
It is of the invention for the problem that the processing method that the waste water that propyl-butyl total solvent is produced is produced currently with Ipomoea batatas is present
Purpose is the processing method of the propyl-butyl total solvent waste water for finding energy stably reaching standard discharge, it is characterised in that by propyl-butyl total solvent waste water
Solid-liquor separation is carried out, the waste water isolated enters regulating reservoir, the solid comprehensive utilization isolated.The third fourth after adjusted pond regulation
Total solvent waste water sends into voltage-resistant reactor, and cleaning iron aluminium composite powder is added into reactor, and is passed through industrial CO2Reacted, iron
The granularity of aluminium composite powder is less than 180 mesh, and the content of every kind of metal is not less than 5% in iron aluminium composite powder（The iron aluminium that return is used is combined
Powder is not limited）, every liter of waste water addition iron aluminium composite powder 5g～30g, the stirring reaction time is 1h～3h, and reaction temperature is 25
DEG C～60 DEG C, CO2Pressure be 0.1MPa～0.6MPa.Reacted waste water carries out solid-liquor separation, and the iron aluminium isolated is combined
Powder Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjusts its pH value to 7.0～8.5, then
Into anaerobic reactor.Waste water stops 24h～120h in anaerobic reactor, and anaerobism temperature is 25 DEG C～55 DEG C.It is useless after anaerobism
Into the process of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 4h～12h to water.Waste water after Aerobic Process for Treatment enters sedimentation basin, sinks
The shallow lake time is 1h～3h.Irregularly extract sludge out from sedimentation basin to be filtered, filter cake makees general disposition of solid waste, filtrate
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 is that activated carbon or porous are made pottery
Grain, is 0.5m～1.0m per thickness degree, and gross thickness is 1m～3m.The dominant bacteria of biological filtering tower combined working is red false single in photosynthetic bacteria
Born of the same parents bacterium（Rhodopseudomonas）.The hydraulic load of biological filtering tower combined working is 50 m3/m2.d～150m3/m2.d.Biological filtering tower combined working goes out
Water qualified discharge or reuse.
The object of the present invention is achieved like this, and the solid matter of propyl-butyl total solvent waste water is more, compound into iron aluminium
Before powder reduction reactor, solid-liquor separation is carried out, it is to avoid the impact that solid matter is reduced to iron aluminium composite powder, be also beneficial to unreacted
Complete iron aluminium composite powder recycling.Waste water is entered after iron aluminium composite powder reduction reactor, the larger molecular organicses in waste water,
Particularly persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）The strong of generation is reduced by iron aluminium composite powder
Reduce the effect of free radical and destroy, be that subsequent biochemical process creates favorable conditions.It is passed through pressure CO2Purpose be maintain iron aluminium
Composite powder reduces suitable pH value（2.0～5.0）, the waste water milk of lime or other alkaline matters after reduction adjusts its pH, with
Meet the requirement of follow-up anaerobic and aerobic process.The premenstrual waste water for stating process in anaerobic processes, by the effect of microorganism, greatly
Molecular organic further becomes small organic molecule, is that more favorable condition is created in subsequent bio oxidation.At biological oxidation
Reason, remaining most of organic matters are removed, while going to denitrogenate the pollutants such as phosphorus.Waste water finally enters activated carbon or porous ceramic grain
Biological filtering tower combined working, in the presence of microorganism, particularly red pseudomonas, the pollutant such as further organics removal and nitrogen phosphorus is protected
Waste water stably reaching standard discharge after card process.
Relative to existing method, the outstanding advantages of the present invention are reduced using iron aluminium composite powder, by the persistence in waste water
Pollutant is destroyed, and is that subsequent biological treatment creates favorable conditions, so as to ensure the waste water stably reaching standard discharge after processing；Relative to
Metal deoxidization used in other wastewater treatments, using CO2Replace now widely used sulfuric acid to make acidulant, do not introduce
SO4 2-Ion, eliminates generation H2The material base of S, so as to avoid H2The pollution of S, while it also avoid SO4 2-To anaerobism and
The inhibitory action of microorganism in aerobic process, greatly improves the efficiency of biological treatment；Boiler, fuel are all had in propyl-butyl total solvent factory
The CO that burning is produced2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；It is useless after process
Water energy stably reaching standard is discharged, with obvious economic benefit and environmental benefit.
