Description

Propyl-butyl total solvent produces the processing method of waste water
Technical field
A kind of processing method of the waste water the present invention relates to be 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 is mainly that raw material produces propyl-butyl total solvent with oil.The third fourth to be produced using biomass ferment always molten in recent years Agent has turned into a kind of development trend.Ipomoea batatas is one of primary raw material of production propyl-butyl total solvent, the organic wastewater that its production is produced 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 of the waste water produced currently with Ipomoea batatas production propyl-butyl total solvent 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 is discharged.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 of the waste water produced currently with Ipomoea batatas production propyl-butyl total solvent 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, under ul-trasonic irradiation and is passed through industry CO2Reacted, the granularity of iron 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（Return The iron aluminium composite powder for using is not limited）, every liter of waste water addition iron aluminium composite powder 5g~30g.Stirred under ul-trasonic irradiation Reaction time is 10min~35min.Reaction temperature is 25 DEG C~60 DEG C.CO2Pressure be 0.1MPa~0.6MPa.Every cube The power of rice waste water input ultrasonic wave is 2kW~8kW.Reacted waste water carries out solid-liquor separation, the iron aluminium composite powder isolated Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjust its pH value to 7.0~8.5, Ran Houjin Enter anaerobic reactor.Waste water stops 24h~120h in anaerobic reactor, and anaerobism temperature is 25 DEG C~55 DEG C.Waste water after anaerobism Into the treatment of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 4h~12h.Waste water after Aerobic Process for Treatment enters sedimentation basin, precipitation Time is 1h~3h.Irregularly extract sludge out from sedimentation basin to be filtered, filter cake makees general 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 0.5m~1.0m per thickness degree, gross thickness is 1m~3m.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 50 m3/m2.d~150m3/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, and the solid matter of propyl-butyl total solvent waste water is more, is combined iron aluminium is entered Before powder reduction reactor, solid-liquor separation is carried out, it is to avoid the influence that solid matter is reduced to iron aluminium composite powder, be also beneficial to unreacted Complete iron aluminium composite powder recycling.After waste water enters 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 treatment creates favorable conditions.It is passed through pressure CO2Purpose be maintain iron aluminium Composite powder reduces suitable pH value（2.0~5.0）；The effect for being input into ultrasonic wave is to speed up the mass transport process of reduction reaction.Reduction Waste water milk of lime or other alkaline matters afterwards adjusts its pH, to meet the requirement of follow-up anaerobic and aerobic process.Through foregoing In anaerobic processes, by the effect of microorganism, larger molecular organicses further become small organic molecule to the waste water for the treatment of, are More favorable condition is created in subsequent bio oxidation.Processed by biological oxidation, remaining most of organic matters are removed, while removal The pollutants such as nitrogen phosphorus.Waste water finally enters activated carbon or porous ceramic grain biological filtering tower combined working, in microorganism, particularly red pseudomonas Under effect, the pollutant such as further organics removal and nitrogen phosphorus, it is ensured that the waste water stably reaching standard discharge after treatment.
Relative to existing method, outstanding advantages of the 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 treatment；Relative to The metal deoxidization used in other wastewater treatments, using CO2Make acidulant instead of now widely used sulfuric acid, 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 Burn the CO for producing2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；It is useless after treatment Water energy stably reaching standard is discharged, with obvious economic benefit and environmental benefit.
