Description
Technical field
The present invention relates to a kind of processing method of Radix Ipomoeae alcohol waste water.
Background technology
Radix Ipomoeae is one of primary raw material of production ethanol, 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 Radix Ipomoeae alcohol waste water（Containing benzene
Ring and（Or）Heterocycle Organic substance）, especially with fresh sweet potatoes be primary raw material when, the concentration of persistence organic pollutant is higher,
Biochemical method Radix Ipomoeae alcohol waste water is thereby resulted in it is difficult to stably reaching standard discharge.The Radix Ipomoeae ethanol 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 Radix Ipomoeae ethanol method of wastewater treatment, the purpose of the present invention is to find energy stably reaching standard discharge
The processing method of Radix Ipomoeae alcohol waste water, it is characterised in that Radix Ipomoeae alcohol waste water is carried out into solid-liquor separation, the waste water isolated is entered
Regulating reservoir, the solid isolated makees feedstuff.Radix Ipomoeae alcohol waste water after adjusted pond is adjusted sends into voltage-resistant reactor, will clean manganese
Powder adds reactor, and is passed through industrial CO2Reacted.The granularity of manganese powder is less than 180 mesh, every liter of waste water add manganese powder 5g~
30g.The stirring reaction time is 10min~40min under ul-trasonic irradiation.Reaction temperature is 25 DEG C~60 DEG C.CO2Pressure be
0.1MPa~0.6MPa.The ultrasonic power of every cubic metre of waste water input is 2kW~8kW.Reacted waste water carries out liquid and divides admittedly
From the manganese powder Returning reactor isolated.Waste water lime cream or other alkaline matters after solid-liquor separation adjusts its pH value and arrives
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 process of biology aerobic pond room temperature, the Aerobic Process for Treatment time is 4h~12h to waste water after anaerobism.Waste water after Aerobic Process for Treatment
Into sedimentation tank, the sedimentation time is 1h~3h.Irregularly extract sludge out from sedimentation tank to be filtered, filter cake is made general solid and given up
Gurry is disposed, and filtrate returns Aerobic Pond.The supernatant waste water of sedimentation tank 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
Rhodopseudomonas 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 of biological filtering tower combined working or reuse.
The object of the present invention is achieved like this, and the solid matter of Radix Ipomoeae alcohol waste water is more, anti-into manganese powder reduction
Before answering device, solid-liquor separation is carried out, it is to avoid the impact that solid matter is reduced to manganese powder, be also beneficial to the complete manganese powder of unreacted and reclaim again
Utilize.Waste water is entered after manganese powder reduction reactor, the larger molecular organicses in waste water, particularly persistence organic pollutant（Contain
Phenyl ring and（Or）The Organic substance of heterocycle etc.）The effect of the strong reduction free radical for producing is reduced by manganese powder and is destroyed, be follow-up life
Change is processed and created favorable conditions.It is passed through pressure CO2Purpose be to maintain manganese powder to reduce suitable pH value（2.0~5.0）；Input is super
The effect of sound wave is the mass transport process of Accelerating reduction reaction.Waste water lime cream or other alkaline matters after reduction adjusts it
PH, to meet the requirement of follow-up anaerobic and aerobic process.The premenstrual waste water for stating process in anaerobic processes, by the work of microorganism
With larger molecular organicses further become small organic molecule, are that more favorable condition is created in subsequent bio oxidation.By biological oxygen
Change is processed, and remaining most of Organic substances are removed, while going to denitrogenate the pollutant such as phosphorus.Waste water finally enters activated carbon or porous
Ceramic aggregate biological filter tower, in the presence of microorganism, particularly rhodopseudomonas, the pollution such as further organics removal and nitrogen phosphorus
Thing, 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 manganese powder, by the persistent pollutant in waste water
Destruction, is that subsequent biological treatment creates favorable conditions, so as to ensure the waste water stably reaching standard discharge after processing；Relative at other
Metal deoxidization used in wastewater treatment, using CO2Replace now widely used sulphuric acid to make acidulant, do not introduce SO4 2-From
Son, eliminates generation H2The material base of S, so as to avoid H2The pollution of S, while it also avoid SO4 2-To anaerobic and aerobic mistake
The inhibitory action of microorganism in journey, greatly improves the efficiency of biological treatment；Boiler is all had in Radix Ipomoeae Alcohol Plant, and fuel combustion is produced
CO2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；Waste water energy after process is stablized
Qualified discharge, with obvious economic benefit and environmental benefit.
