Abstract

The processing method of the Ipomoea batatas alcohol waste water that the present invention is introduced includes solid-liquor separation, the CO under ul-trasonic irradiation2The operations such as the reduction of pressurization MnZn composite powder, anaerobism, the treatment of aerobic and biological filtering tower combined working, the waste water after treatment can stably reaching standard discharge.

Description

The processing method of Ipomoea batatas alcohol waste water
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 manganese Zinc composite powder adds reactor, and is passed through industrial CO2Reacted.The granularity of MnZn composite powder is less than 180 mesh, MnZn composite powder In the content of every kind of metal be not less than 5%（The MnZn composite powder that return is used is not limited）, every liter of waste water adds MnZn to be combined Powder 5g~30g.The stirring reaction time is 10min~40min under ul-trasonic irradiation.Reaction temperature is 25 DEG C~60 DEG C.CO2's Pressure is 0.1MPa~0.6MPa.The ultrasonic power of every cubic metre of waste water input is 2kW~8kW.Reacted waste water is carried out Solid-liquor separation, the MnZn composite powder Returning reactor isolated.Waste water milk of lime or other alkaline matters after solid-liquor separation Its pH value to 7.0~8.5 is adjusted, subsequently into anaerobic reactor.Waste water stops 24h~120h, anaerobism temperature in anaerobic reactor Spend is 25 DEG C~55 DEG C.Into the treatment of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 4h~12h to waste water after anaerobism.It is aerobic Waste water after treatment enters sedimentation basin, and the sedimentation time is 1h~3h.Irregularly extract sludge out from sedimentation basin to be filtered, filter cake Make general disposition of solid waste, filtrate returns to Aerobic Pond.The supernatant waste water of sedimentation basin send multi-layer biological filter tower to process.Biological filter The filler of tower is activated carbon or porous ceramic grain, is 0.5m~1.0m per thickness degree, and gross thickness is 1m~3m.The advantage of biological filtering tower combined working Strain 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 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 MnZn composite powder Before reduction reactor, solid-liquor separation is carried out, it is to avoid the influence 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 matter 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 treatment create favorable conditions.It is passed through pressure CO2Purpose be maintain MnZn answer Close powder and reduce suitable pH value（2.0~5.0）；The effect for being input into ultrasonic wave is the mass transport process of Accelerating reduction reaction.After reduction Waste water milk of lime or other alkaline matters adjust its pH, to meet the requirement of follow-up anaerobic and aerobic process.Through foregoing place In anaerobic processes, by the effect of microorganism, larger molecular organicses further become small organic molecule to the waste water of reason, after being Continuous biological oxidation creates more favorable condition.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 biological filtering tower combined working, in the work of microorganism, particularly red pseudomonas Under, the pollutant such as further organics removal and nitrogen phosphorus, 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 MnZn 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.
