Abstract
The processing method of the propyl-butyl total solvent production waste water that the present invention is introduced includes solid-liquor separation, CO2The operations such as the reduction of pressurization iron zinc composite powder, anaerobism, the treatment of aerobic and biological filtering tower combined working, the waste water after treatment can stably reaching standard discharge.
Description
Technical field
A kind of processing method of the waste water the present invention relates to be produced as main material production propyl-butyl total solvent with Ipomoea batatas.
Background technology
Acetone, butanol, ethanol are referred to as propyl-butyl total solvent, are medicine, agricultural chemicals, plastics, paint, national defence and light industry
Important source material, early stage is mainly that raw material produces propyl-butyl total solvent with oil.The third fourth to be produced using biomass ferment always molten in recent years
Agent has turned into a kind of development trend.Ipomoea batatas is one of primary raw material of production propyl-butyl total solvent, the organic wastewater that its production is produced
Middle pollutant COD concentration is high, and complicated component, intractability is big.If the waste water is not processed is directly discharged into environment, environment will be caused
Severe contamination.The processing method of the waste water produced currently with Ipomoea batatas production propyl-butyl total solvent is mainly biological treatment.Due to
Contain persistence organic pollutant in the waste water（Containing phenyl ring and（Or）Heterocycle organic matter）, it is main former especially with fresh sweet potatoes
During material, the concentration of persistence organic pollutant is higher, thereby results in the Biochemical method waste water it is difficult to stably reaching standard is discharged.Exploitation
The processing method of the waste water that the utilization Ipomoea batatas production propyl-butyl total solvent of energy stably reaching standard discharge is produced has larger practical value.
The content of the invention
It is of the invention for the problem that the processing method of the waste water produced currently with Ipomoea batatas production propyl-butyl total solvent is present
Purpose is the processing method of the propyl-butyl total solvent waste water for finding energy stably reaching standard discharge, it is characterised in that by propyl-butyl total solvent waste water
Solid-liquor separation is carried out, the waste water isolated enters regulating reservoir, the solid comprehensive utilization isolated.The third fourth after adjusted pond regulation
Total solvent waste water sends into voltage-resistant reactor, cleaning iron zinc composite powder is added into reactor, and be passed through industrial CO2Reacted, iron
The granularity of zinc composite powder is less than 180 mesh, and the content of every kind of metal is not less than 5% in iron zinc composite powder（The iron zinc that return is used is combined
Powder is not limited）, every liter of waste water addition iron zinc composite powder 5g~30g, the stirring reaction time is 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, and the iron zinc isolated is combined
Powder Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjust its pH value to 7.0~8.5, then
Into anaerobic reactor.Waste water stops 24h~120h in anaerobic reactor, and anaerobism temperature is 25 DEG C~55 DEG C.It is useless after anaerobism
Into the treatment of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 4h~12h to water.Waste water after Aerobic Process for Treatment enters sedimentation basin, sinks
The shallow lake time is 1h~3h.Irregularly extract sludge out from sedimentation basin to be filtered, filter cake makees general disposition of solid waste, filtrate
Return to Aerobic Pond.The supernatant waste water of sedimentation basin send multi-layer biological filter tower to process.The filler of biological filtering tower combined working is activated carbon or porous pottery
Grain, is 0.5m~1.0m per thickness degree, and gross thickness is 1m~3m.The dominant bacteria of biological filtering tower combined working is the red false list in photosynthetic bacteria
Born of the same parents bacterium（Rhodopseudomonas）.The hydraulic load of biological filtering tower combined working is 50 m3/m2.d~150m3/m2.d.Biological filtering tower combined working goes out
Water qualified discharge or reuse.
The object of the present invention is achieved like this, and the solid matter of propyl-butyl total solvent waste water is more, is combined iron zinc is entered
Before powder reduction reactor, solid-liquor separation is carried out, it is to avoid the influence that solid matter is reduced to iron zinc composite powder, be also beneficial to unreacted
Complete iron zinc composite powder recycling.After waste water enters iron zinc composite powder reduction reactor, the larger molecular organicses in waste water,
Particularly persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）The strong of generation is reduced by iron zinc composite powder
Reduce the effect of free radical and destroy, be that subsequent biochemical treatment creates favorable conditions.It is passed through pressure CO2Purpose be maintain iron zinc
Composite powder reduces suitable pH value（2.0~5.0）, waste water milk of lime or other alkaline matters after reduction adjusts its pH, with
Meet the requirement of follow-up anaerobic and aerobic process.Through the waste water of aforementioned processing in anaerobic processes, by the effect of microorganism, greatly
Molecular organic further becomes small organic molecule, is that more favorable condition is created in subsequent bio oxidation.At biological oxidation
Reason, 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 presence of microorganism, particularly red pseudomonas, the pollutant such as further organics removal and nitrogen phosphorus is protected
Waste water stably reaching standard discharge after card treatment.
Relative to existing method, outstanding advantages of the invention are reduced using iron zinc 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 are all had in propyl-butyl total solvent factory
Burn the CO for producing2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；It is useless after treatment
Water energy stably reaching standard is discharged, with obvious economic benefit and environmental benefit.
