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 manganese
Zinc composite powder adds reactor, and is passed through industrial CO2Reacted, the granularity of MnZn composite powder is less than 180 mesh, and cleaning MnZn is multiple
The content for closing each metal in powder is not less than 5%（The MnZn composite powder that return is used is not limited）, every liter of waste water addition
MnZn composite powder 5g~30g, stirring reaction time are 1h~3h, and reaction temperature is 25 DEG C~60 DEG C, CO2Pressure be 0.1MPa
~0.6MPa.Reacted waste water carries out solid-liquor separation, the MnZn composite powder Returning reactor isolated.It is useless after solid-liquor separation
Water lime cream 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 into the process of biology aerobic pond room temperature, good
Oxygen process time is 4h~12h.Waste water after Aerobic Process for Treatment enters sedimentation tank, and the sedimentation time is 1h~3h.Irregularly from precipitation
Extract sludge out to be filtered in pond, filter cake makees general disposition of solid waste, filtrate returns Aerobic Pond.The supernatant waste water of sedimentation tank
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 per thickness degree, total thickness
Spend for 1m~3m.The dominant bacteria of biological filtering tower combined working is the rhodopseudomonas 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 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, into MnZn composite powder
Before 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.After waste water enters MnZn 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 substance of heterocycle etc.）The strong also of generation is reduced by MnZn composite powder
The effect of former free radical and destroy, be subsequent biochemical process create favorable conditions.It is passed through pressure CO2Purpose be to maintain MnZn multiple
Close powder and reduce suitable pH value（2.0~5.0）, the waste water lime cream or other alkaline matters after reduction adjusts its pH, with full
The requirement of the follow-up anaerobic and aerobic process of foot.The premenstrual waste water for stating process is in anaerobic processes, by the effect of microorganism, big to divide
Sub- Organic substance further becomes small organic molecule, is that more favorable condition is created in subsequent bio oxidation.By biological oxidation process,
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 grain life
Thing filter tower, in the presence of microorganism, particularly rhodopseudomonas, the pollutant such as further organics removal and nitrogen phosphorus, it is ensured that
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 persistency in waste water
Pollutant are destroyed, and are 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 sulphuric 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 combustion are all had in Radix Ipomoeae 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 process
Energy stably reaching standard discharge, with obvious economic benefit and environmental benefit.
