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-aluminum-manganese composite powder is added into reactor, under ul-trasonic irradiation and is passed through work Industry CO2Reacted, the granularity of iron-aluminum-manganese composite powder is less than 180 mesh, and the content of every kind of metal is not less than in iron-aluminum-manganese composite powder 5%（The iron-aluminum-manganese composite powder that return is used is not limited）, every liter of waste water addition iron-aluminum-manganese composite powder 5g~30g.In ultrasonic wave The effect lower stirring reaction time is 10min~35min.Reaction temperature is 25 DEG C~60 DEG C.CO2Pressure for 0.1MPa~ 0.6MPa.The power of every cubic metre of waste water input ultrasonic wave is 2kW~8kW.Reacted waste water carries out solid-liquor separation, isolates Iron-aluminum-manganese composite powder Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjust its pH value and arrive 7.0~8.5, subsequently into anaerobic reactor.Waste water stops 24h~120h in anaerobic reactor, and anaerobism temperature is 25 DEG C~55 ℃.Into the treatment of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 4h~12h to waste water after anaerobism.Waste water after Aerobic Process for Treatment Into sedimentation basin, the sedimentation time is 1h~3h.Irregularly extract sludge out from sedimentation basin to be filtered, filter cake is made general solid and given up Gurry is disposed, and filtrate returns to 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 work Property charcoal or porous ceramic grain, be 0.5m~1.0m per thickness degree, gross thickness is 1m~3m.The dominant bacteria of biological filtering tower combined working is photosynthetic thin Red pseudomonas in bacterium（Rhodopseudomonas）.The hydraulic load of biological filtering tower combined working is 50 m3/m2.d~150m3/m2.d。 The standard water discharge discharge or reuse of biological filtering tower combined working.
The object of the present invention is achieved like this, and the solid matter of propyl-butyl total solvent waste water is more, is answered iron-aluminum-manganese is entered Before closing powder reduction reactor, solid-liquor separation is carried out, it is to avoid the influence that solid matter is reduced to iron-aluminum-manganese composite powder, be also beneficial to not The iron-aluminum-manganese composite powder recycling reacted.After waste water enters iron-aluminum-manganese composite powder reduction reactor, big point in waste water Sub- organic matter, particularly persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）By iron-aluminum-manganese composite powder also Originate in the effect of raw strong reduction free radical and destroy, be that subsequent biochemical treatment creates favorable conditions.It is passed through pressure CO2Purpose It is to maintain iron-aluminum-manganese composite powder to reduce suitable pH value（2.0~5.0）；The effect for being input into ultrasonic wave is to speed up the biography of reduction reaction Matter process.Waste water milk of lime or other alkaline matters after reduction adjust its pH, to meet follow-up anaerobic and aerobic process It is required that.Through the waste water of aforementioned processing in anaerobic processes, by the effect of microorganism, larger molecular organicses further become small point Sub- organic matter, is that more favorable condition is created in subsequent bio oxidation.Processed by biological oxidation, remaining most of organic matters are gone Remove, 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 microorganism, particularly In the presence of red pseudomonas, the pollutant such as further organics removal and nitrogen phosphorus, it is ensured that the waste water stably reaching standard row after treatment Put.
Relative to existing method, outstanding advantages of the invention are reduced using iron-aluminum-manganese composite powder, will be lasting in waste water Contact scar thing is destroyed, and is that subsequent biological treatment creates favorable conditions, so as to ensure the waste water stably reaching standard discharge after treatment；Relatively In the metal deoxidization used in other wastewater treatments, using CO2Make acidulant instead of now widely used sulfuric acid, do not draw Enter 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 With it is aerobic during microorganism inhibitory action, greatly improve the efficiency of biological treatment；Boiler is all had in propyl-butyl total solvent factory, combustion The CO that material burning is produced2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；After treatment Waste water energy stably reaching standard is discharged, with obvious economic benefit and environmental benefit.
