The invention introduces a sweet potato alcohol wastewater treatment method. The method comprises the procedures of solid-liquid separation, CO2 pressurized reduction of iron aluminum manganese composite powder, anaerobic treatment, aerobic treatment, biological filtration tower treatment and the like, and the treated wastewater can be stably discharged to reach the standard.
Description
Technical field
The present invention relates to a kind of processing method of Ipomoea batatas alcohol waste water.
Background technology
Ipomoea batatas is one of primary raw material of production alcohol, and 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.Current sweet potato wine
The processing method of smart waste water is mainly biological treatment.Due to containing persistence organic pollutant in Ipomoea batatas alcohol waste water（Containing benzene
Ring and（Or）Heterocycle organic matter）, during especially with fresh sweet potatoes for primary raw material, the concentration of persistence organic pollutant is higher,
Biochemical method Ipomoea batatas alcohol waste water is thereby resulted in it is difficult to stably reaching standard is discharged.The Ipomoea batatas alcohol of exploitation energy stably reaching standard discharge gives up
The processing method of water has larger practical value.
The content of the invention
For the problem of current Ipomoea batatas alcohol method of wastewater treatment, the purpose of the present invention is to find energy stably reaching standard discharge
The processing method of Ipomoea batatas alcohol waste water, it is characterised in that Ipomoea batatas alcohol waste water is carried out into solid-liquor separation, the waste water isolated enters
Regulating reservoir, the solid isolated makees feed.Ipomoea batatas alcohol waste water feeding voltage-resistant reactor after adjusted pond regulation, will clean iron
Aluminium manganese composite powder adds reactor, and is passed through industrial CO2Reacted, the granularity of iron-aluminum-manganese composite powder is less than 180 mesh, cleans iron
The content of each metal in aluminium manganese composite powder is not less than 5%（The iron-aluminum-manganese composite powder that return is used is not limited）, every liter
Waste water adds iron-aluminum-manganese composite powder 5g~30g, and the stirring reaction time is 1h~3h, and reaction temperature is 25 DEG C~60 DEG C, CO2Pressure
Power is 0.1MPa~0.6MPa.Reacted waste water carries out solid-liquor separation, the iron-aluminum-manganese composite powder Returning reactor isolated.Liquid
Gu the waste water milk of lime or other alkaline matters after separating adjust its pH value to 7.0~8.5, subsequently into anaerobic reactor.
Waste water stops 24h~120h in anaerobic reactor, and anaerobism temperature is 25 DEG C~55 DEG C.Waste water after anaerobism enters biology aerobic pond
Normal temperature treatment, the Aerobic Process for Treatment time is 4h~12h.Waste water after Aerobic Process for Treatment enters sedimentation basin, and the sedimentation time is 1h~3h.No
Periodically extract sludge out from sedimentation basin to be filtered, filter cake makees general disposition of solid waste, filtrate returns to Aerobic Pond.Sedimentation basin
Supernatant waste water send multi-layer biological filter tower process.The filler of biological filtering tower combined working is activated carbon or porous ceramic grain, is 0.5m per thickness degree
~1.0m, gross thickness is 1m~3m.The dominant bacteria of biological filtering tower combined working is the red pseudomonas in photosynthetic bacteria
（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 reaches
Mark discharge or reuse.
The object of the present invention is achieved like this, and the solid matter of Ipomoea batatas alcohol waste water is more, is combined iron-aluminum-manganese 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-aluminum-manganese composite powder, be also beneficial to not anti-
The iron-aluminum-manganese composite powder recycling answered.After waste water enters iron-aluminum-manganese composite powder reduction reactor, the macromolecular in waste water
Organic matter, particularly persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）Reduced by iron-aluminum-manganese composite powder
Produce strong reduction free radical effect and destroy, be subsequent biochemical treatment create favorable conditions.It is passed through pressure CO2Purpose be
Iron-aluminum-manganese composite powder is maintained to reduce suitable pH value（2.0~5.0）, waste water milk of lime or other alkaline matters after reduction are adjusted
Its pH is saved, to meet the requirement of follow-up anaerobic and aerobic process.Through the waste water of aforementioned processing in anaerobic processes, by microorganism
Effect, larger molecular organicses further become small organic molecule, are that more favorable condition is created in subsequent bio oxidation.By life
Thing oxidation processes, remaining most of organic matters are removed, while going to denitrogenate the pollutants such as phosphorus.Waste water finally enter activated carbon or
Porous ceramic grain biological filtering tower combined working, in the presence of microorganism, particularly red pseudomonas, the dirt such as further organics removal and nitrogen phosphorus
Dye thing, 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-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, fuel are all had in Ipomoea batatas Alcohol Plant
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.
