Description
Technical field
The present invention relates to a kind of processing method of Radix Ipomoeae alcohol waste water.
Background technology
Radix Ipomoeae is to produce one of primary raw material of 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,
Thereby result in Biochemical method Radix Ipomoeae alcohol waste water and be difficult 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 solid-liquor separation, the waste water isolated are entered
Regulating reservoir, the solid isolated make feedstuff.Radix Ipomoeae alcohol waste water after adjusted pond is adjusted sends into voltage-resistant reactor, will clean ferrum
MnZn composite powder adds reactor, and is passed through industrial CO2Reacted.The granularity of ferrimanganic zinc composite powder is less than 180 mesh, ferrimanganic zinc
In composite powder, the content of every kind of metal is not less than 5%（The ferrimanganic zinc composite powder that return is used is not limited）, every liter of waste water addition
Ferrimanganic zinc composite powder 5g~30g.Under ul-trasonic irradiation, the stirring reaction time is 10min~40min.Reaction temperature be 25 DEG C~
60℃。CO2Pressure be 0.1MPa~0.6MPa.The ultrasonic power of every cubic metre of waste water input is 2kW~8kW.After reaction
Waste water carry out solid-liquor separation, the ferrimanganic zinc composite powder Returning reactor isolated.Waste water lime cream after solid-liquor separation or
Other alkaline matters adjust its pH value to 7.0~8.5, subsequently into anaerobic reactor.Waste water anaerobic reactor stop 24h~
120h, anaerobism temperature are 25 DEG C~55 DEG C.Into the process of biology aerobic pond room temperature, the Aerobic Process for Treatment time is 4h to waste water after anaerobism
~12h.Waste water after Aerobic Process for Treatment enters sedimentation tank, and the sedimentation time is 1h~3h.Irregularly extract sludge out from sedimentation tank to enter
Row is filtered, and filter cake makees general disposition of solid waste, and filtrate returns Aerobic Pond.The supernatant waste water of sedimentation tank 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~1.0m per thickness degree, and gross thickness is 1m~3m.It is raw
The dominant bacteria of thing filter tower is the rhodopseudomonas in photosynthetic bacteria（Rhodopseudomonas）.The hydraulic load of biological filtering tower combined working
For 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, compound into ferrimanganic zinc
Before powder reduction reactor, solid-liquor separation is carried out, it is to avoid the impact that solid matter is reduced to ferrimanganic zinc composite powder, be also beneficial to not anti-
The ferrimanganic zinc composite powder recycling answered.After waste water enters ferrimanganic zinc composite powder reduction reactor, the macromole in waste water
Organic substance, particularly persistence organic pollutant（Containing phenyl ring and（Or）The Organic substance of heterocycle etc.）Reduced by ferrimanganic zinc composite powder
Produce strong reduction free radical effect and destroy, be subsequent biochemical process create favorable conditions.It is passed through pressure CO2Purpose be
Ferrimanganic zinc composite powder is maintained to reduce suitable pH value（2.0~5.0）；The effect of input ultrasound wave is the mass transfer of Accelerating reduction reaction
Process.Waste water lime cream or other alkaline matters after reduction adjusts its pH, to meet wanting for follow-up anaerobic and aerobic process
Ask.In anaerobic processes, by the effect of microorganism, larger molecular organicses further become small molecule to the premenstrual waste water for stating process
Organic substance, is that more favorable condition is created in subsequent bio oxidation.By biological oxidation process, remaining most of Organic substances are gone
Remove, while going to denitrogenate the pollutant 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 rhodopseudomonas, the pollutant such as further organics removal and nitrogen phosphorus, it is ensured that the waste water stably reaching standard row after process
Put.
Relative to existing method, the outstanding advantages of the present invention are reduced using ferrimanganic zinc 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 processing；Relatively
In the metal deoxidization used in other wastewater treatments, using CO2Replace now widely used sulphuric acid to make acidulant, 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 Radix Ipomoeae Alcohol Plant
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.
