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 MnZn composite powder is added into reactor, under ul-trasonic irradiation and is passed through industry
CO2Reacted, the granularity of MnZn composite powder is less than 180 mesh, and the content of every kind of metal is not less than 5% in MnZn composite powder(Return
The MnZn composite powder for using is not limited), every liter of waste water addition MnZn composite powder 5g~30g.Stir under ul-trasonic irradiation
Reaction time is 10min~35min.Reaction temperature is 25 DEG C~60 DEG C.CO2Pressure be 0.1MPa~0.6MPa.Per cube
The power of rice waste water input ultrasonic wave is 2kW~8kW.Reacted waste water carries out solid-liquor separation, the MnZn composite powder isolated
Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjusts 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 process 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 is 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, compound into MnZn
Before powder reduction reactor, solid-liquor separation is carried out, it is to avoid the impact that solid matter is reduced to MnZn composite powder, be also beneficial to unreacted
Complete MnZn composite powder recycling.Waste water is entered after MnZn 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 MnZn 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 MnZn
Composite powder reduces suitable pH value(2.0~5.0);The effect of input 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.It is premenstrual to state
In anaerobic processes, by the effect of microorganism, larger molecular organicses further become small organic molecule to the waste water of process, are
More favorable condition is created in subsequent bio oxidation.By biological oxidation process, remaining most of organic matters are removed, while removing
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 process.
Relative to existing method, the outstanding advantages of the present invention are reduced using MnZn 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.
