Description

Propyl-butyl total solvent produces the processing method of waste water
Technical field
The present invention relates to a kind of processing method of the waste water 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 mainly produce propyl-butyl total solvent by raw material of oil.The third fourth is produced using biomass ferment in recent years always molten Agent has become a kind of development trend.Ipomoea batatas is to produce one of primary raw material of propyl-butyl total solvent, the organic wastewater that its production is produced Middle pollutant COD concentration is high, and complicated component, intractability are big.If the waste water is not processed is directly discharged into environment, environment will be caused Severe contamination.The processing method that the waste water that propyl-butyl total solvent is produced is produced currently with Ipomoea batatas 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 and is difficult stably reaching standard discharge.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 for the problem that the processing method that the waste water that propyl-butyl total solvent is produced is produced currently with Ipomoea batatas is present, of the invention 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, and cleaning ferrimanganic zinc composite powder is added reactor, under ul-trasonic irradiation and is passed through work Industry CO2Reacted, the granularity of ferrimanganic zinc composite powder is less than 180 mesh, and in ferrimanganic zinc 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.In ultrasonic wave The effect lower stirring reaction time is 10min～35min.Reaction temperature is 25 DEG C～60 DEG C.CO2Pressure be 0.1MPa～ 0.6MPa.The power of every cubic metre of waste water input ultrasonic wave is 2kW～8kW.Reacted waste water carries out solid-liquor separation, isolates Ferrimanganic zinc composite powder Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjusts its pH value and arrives 7.0～8.5, subsequently into anaerobic reactor.Waste water stops 24h～120h in anaerobic reactor, and anaerobism temperature is 25 DEG C～55 ℃.Into the process of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 4h～12h to waste water after anaerobism.Waste water after Aerobic Process for Treatment Into sedimentation basin, the sedimentation time is 1h～3h.Irregularly extract sludge out from sedimentation basin to be filtered, filter cake is made general solid and given up Gurry is disposed, and filtrate returns 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 work Property charcoal or porous ceramic grain, be 0.5m～1.0m per thickness degree, gross thickness is 1m～3m.The dominant bacteria of biological filtering tower combined working is photosynthetic thin Red pseudomonas in bacterium（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 propyl-butyl total solvent waste water is more, multiple into ferrimanganic zinc Before closing powder reduction reactor, carry out solid-liquor separation, it is to avoid the impact that solid matter is reduced to ferrimanganic zinc composite powder, be also beneficial to not The ferrimanganic zinc composite powder recycling reacted.After waste water enters ferrimanganic zinc composite powder reduction reactor, big point in waste water Sub- organic matter, particularly persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）By ferrimanganic zinc composite powder also Originate in the effect of raw strong reduction free radical and destroy, be that subsequent biochemical process creates favorable conditions.It is passed through pressure CO2Purpose It is to maintain ferrimanganic zinc composite powder to reduce suitable pH value（2.0～5.0）；The effect of input ultrasonic wave is to speed up the biography of reduction reaction Matter process.Waste water milk of lime or other alkaline matters after reduction adjusts its pH, to meet follow-up anaerobic and aerobic process Require.In anaerobic processes, by the effect of microorganism, larger molecular organicses further become little point to the premenstrual waste water for stating process Sub- organic matter, is that more favorable condition is created in subsequent bio oxidation.By biological oxidation process, remaining most of organic matters are gone Remove, 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 microorganism, particularly In the presence of red pseudomonas, 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 sulfuric 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 is all had in propyl-butyl total solvent factory, combustion The CO that material burning is produced2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；After process Waste water energy stably reaching standard is discharged, with obvious economic benefit and environmental benefit.
