Description

The processing method of Radix Ipomoeae alcohol waste water
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 Manganese composite powder adds reactor, and is passed through industrial CO2Reacted.The granularity of ferrimanganic composite powder is less than 180 mesh, ferrimanganic composite powder In the content of every kind of metal be not less than 5%（The ferrimanganic composite powder that return is used is not limited）, every liter of waste water adds ferrimanganic to be combined Powder 5g~30g.Under ul-trasonic irradiation, the stirring reaction time is 10min~40min.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 ferrimanganic composite powder Returning reactor isolated.Waste water lime cream or other alkaline matters after solid-liquor separation Its pH value is adjusted to 7.0~8.5, subsequently into anaerobic reactor.Waste water stops 24h~120h, anaerobism temperature in anaerobic reactor Spend for 25 DEG C~55 DEG C.Into the process of biology aerobic pond room temperature, the Aerobic Process for Treatment time is 4h~12h to waste water after anaerobism.It is aerobic Waste water after process enters sedimentation tank, and the sedimentation time is 1h~3h.Irregularly extract sludge out from sedimentation tank to be filtered, filter cake Make general disposition of solid waste, filtrate returns Aerobic Pond.The supernatant waste water of sedimentation tank 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 rhodopseudomonas 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 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 ferrimanganic composite powder Before reduction reactor, solid-liquor separation is carried out, it is to avoid the impact that solid matter is reduced to ferrimanganic composite powder, be also beneficial to unreacted complete Ferrimanganic composite powder recycling.After waste water enters ferrimanganic 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 ferrimanganic 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 ferrimanganic multiple Close powder and reduce suitable pH value（2.0~5.0）；The effect of input ultrasound wave is the mass transport process of Accelerating reduction reaction.After reduction Waste water lime cream or other alkaline matters adjust its pH, to meet the requirement of follow-up anaerobic and aerobic process.It is premenstrual to state 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.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 biological filtering tower combined working, in the work of microorganism, particularly rhodopseudomonas With under, the pollutant such as further organics removal and nitrogen phosphorus, 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 ferrimanganic 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.
