The invention provides a treatment method of sweet potato alcohol wastewater. The treatment method comprises the procedures of carrying out liquid-solid separation, reducing by CO2 pressurized iron-zinc composite powder, carrying out anaerobic and aerobic treatment, and treating by a biological filtering tower and the like. The treated wastewater can stably reach emission standards and then is discharged.
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
Zinc composite powder adds reactor, and is passed through industrial CO2Reacted, the granularity of iron zinc composite powder is less than 180 mesh, and cleaning iron zinc is answered
The content for closing each metal in powder is not less than 5%(The iron zinc composite powder that return is used is not limited), every liter of waste water addition
Iron zinc composite powder 5g~30g, the stirring reaction time be 1h~3h, reaction temperature be 25 DEG C~60 DEG C, CO2Pressure be 0.1MPa
~0.6MPa.Reacted waste water carries out solid-liquor separation, the iron zinc composite powder Returning reactor isolated.It is useless after solid-liquor separation
Water milk of lime or other alkaline matters adjust its pH value to 7.0~8.5, subsequently into anaerobic reactor.Waste water is anti-in anaerobism
Device is answered to stop 24h~120h, anaerobism temperature is 25 DEG C~55 DEG C.Waste water after anaerobism is good into the treatment of biology aerobic pond normal temperature
Oxygen process time is 4h~12h.Waste water after Aerobic Process for Treatment enters sedimentation basin, and the sedimentation time is 1h~3h.Irregularly from precipitation
Extract sludge in pond out to be filtered, filter cake makees general disposition of solid waste, filtrate returns to Aerobic Pond.The supernatant waste water of sedimentation basin
Multi-layer biological filter tower is sent to process.The filler of biological filtering tower combined working is activated carbon or porous ceramic grain, is 0.5m~1.0m, total thickness per thickness degree
It is 1m~3m to spend.The dominant bacteria of biological filtering tower combined working is the red pseudomonas in photosynthetic bacteria(Rhodopseudomonas).It is biological
The hydraulic load of filter tower 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 Ipomoea batatas alcohol waste water is more, is entering iron zinc composite powder
Before reduction reactor, solid-liquor separation is carried out, it is to avoid the influence that solid matter is reduced to iron zinc composite powder, be also beneficial to unreacted complete
Iron zinc composite powder recycling.After waste water enters iron zinc composite powder reduction reactor, the larger molecular organicses in waste water are special
It is not persistence organic pollutant(Containing phenyl ring and(Or)The organic matter of heterocycle etc.)The strong also of generation is reduced by iron zinc composite powder
The effect of former free radical and destroy, be subsequent biochemical treatment create favorable conditions.It is passed through pressure CO2Purpose be to maintain iron zinc to answer
Close powder and reduce suitable pH value(2.0~5.0), waste water milk of lime or other alkaline matters after reduction adjust its pH, with full
The requirement of the follow-up anaerobic and aerobic process of foot.Through the waste water of aforementioned processing in anaerobic processes, by the effect of microorganism, big point
Sub- organic matter further becomes small organic molecule, is that more favorable condition is created in subsequent bio oxidation.Processed by biological oxidation,
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 life
Thing filter tower, in the presence of microorganism, particularly red pseudomonas, the pollutant such as further organics removal and nitrogen phosphorus, it is ensured that
Waste water stably reaching standard discharge after treatment.
Relative to existing method, outstanding advantages of the invention are reduced using iron zinc 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 combustion 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;Waste water after treatment
Energy stably reaching standard discharge, with obvious economic benefit and environmental benefit.
