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 produces propyl-butyl total solvent by raw material of oil.Produce the third fourth using biomass ferment in recent years always molten Agent has become a kind of development trend.Ipomoea batatas is one of primary raw material of production propyl-butyl total solvent, and it produces the organic wastewater for producing 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 for producing the waste water that propyl-butyl total solvent 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 it is difficult to 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 of the invention 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 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 iron powder is added into reactor, under ul-trasonic irradiation and is passed through industrial CO2Carry out Reaction, the granularity of iron powder is less than 180 mesh, and every liter of waste water adds iron powder 5g～30g.The stirring reaction time is under ul-trasonic irradiation 10min～35min.Reaction temperature is 25 DEG C～60 DEG C.CO2Pressure be 0.1MPa～0.6MPa.Every cubic metre of waste water input The power of ultrasonic wave is 2kW～8kW.Reacted waste water carries out solid-liquor separation, the iron powder Returning reactor isolated.Liquid divides admittedly Waste water milk of lime or other alkaline matters after adjusts its pH value to 7.0～8.5, subsequently into anaerobic reactor.Waste water 24h～120h is stopped in anaerobic reactor, anaerobism temperature is 25 DEG C～55 DEG C.Waste water after anaerobism enters biology aerobic pond normal temperature Process, the Aerobic Process for Treatment time is 4h～12h.Waste water after Aerobic Process for Treatment enters sedimentation basin, and the sedimentation time is 1h～3h.Irregularly Extract sludge out from sedimentation basin to be filtered, filter cake makees general disposition of solid waste, filtrate returns Aerobic Pond.Sedimentation basin it is upper Stripping water send multi-layer biological filter tower to process.The filler of biological filtering tower combined working is activated carbon or porous ceramic grain, be per thickness degree 0.5m～ 1.0m, gross thickness is 1m～3m.The dominant bacteria of biological filtering tower combined working 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 water outlet of biological filtering tower combined working reaches Mark 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 entering iron powder reducing Before reactor, solid-liquor separation is carried out, it is to avoid impact of the solid matter to iron powder reducing, be also beneficial to the complete iron powder of unreacted and reclaim Recycle.Waste water is entered after iron powder reducing reactor, the larger molecular organicses in waste water, particularly persistence organic pollutant （Containing phenyl ring and（Or）The organic matter of heterocycle etc.）Destroyed by the effect of the strong reduction free radical that iron powder reducing is produced, be follow-up Biochemical treatment creates favorable conditions.It is passed through pressure CO2Purpose be to maintain the suitable pH value of iron powder reducing（2.0～5.0）；Input The effect of ultrasonic wave is to speed up the mass transport process of reduction reaction.Waste water milk of lime or other alkaline matters after reduction adjusts it PH, to meet the requirement of follow-up anaerobic and aerobic process.The premenstrual waste water for stating process in anaerobic processes, by the work of microorganism With larger molecular organicses further become small organic molecule, are that more favorable condition is created in subsequent bio oxidation.By biological oxygen Change is processed, and 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 aggregate biological filter tower, in the presence of microorganism, particularly red pseudomonas, the pollution such as further organics removal and nitrogen phosphorus Thing, 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 to adopt iron powder reducing, by the persistent pollutant in waste water Destruction, is that subsequent biological treatment creates favorable conditions, so as to ensure the waste water stably reaching standard discharge after processing；Relative at other Metal deoxidization used in wastewater treatment, using CO2Replace now widely used sulfuric acid to make acidulant, do not introduce SO4 2-From Son, eliminates generation H2The material base of S, so as to avoid H2The pollution of S, while it also avoid SO4 2-To anaerobic and aerobic mistake The inhibitory action of microorganism in journey, greatly improves the efficiency of biological treatment；Boiler is all had in propyl-butyl total solvent factory, and fuel combustion is produced Raw CO2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；Waste water energy after process is steady Qualified discharge is determined, with obvious economic benefit and environmental benefit.
