Abstract
The processing method of the chemical industrial organic wastewater that the present invention is introduced includes CO2Pressurize and the operation such as aluminum reduction, anaerobism, the treatment of aerobic and biological filtering tower combined working under ul-trasonic irradiation, the waste water after treatment can stably reaching standard discharge.
Description
Technical field
The present invention relates to a kind of processing method of chemical industrial organic wastewater.
Background technology
Organic chemical industry is one of mainstay of the national economy industry, the organic waste water pollutant COD concentration that its production is produced
Height, complicated component particularly contains persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）When, intractability
Greatly.If the waste water is not processed is directly discharged into environment, severe contamination will be caused to environment.Contain persistence organic pollutant at present
The processing method of chemical industrial organic wastewater mainly first carries out advanced oxidation（Such as iron-carbon micro-electrolysis, metal powder reduction, Fenton methods
Deng）Pretreatment, then biological treatment.In advanced oxidation preprocessing process, sulfuric acid is generally needed to be added, caused at subsequent bio
Reason（Such as anaerobism, hydrolysis acidification）During produce H2S, produces more serious secondary pollution；Simultaneously because SO4 2-To microorganism
Growth has obvious inhibitory action, influences biological treatment effect, and waste water is difficult to stably reaching standard discharge.Exploitation secondary pollution is small, energy
The processing method of the chemical industrial organic wastewater of stably reaching standard discharge has larger practical value.
The content of the invention
For the problem of current chemical industrial organic wastewater processing method, the purpose of the present invention be find secondary pollution it is small, can be steady
Determine the processing method of the chemical industrial organic wastewater of qualified discharge, it is characterised in that after pH value is more than into 5.0, and the regulation of adjusted pond
Chemical industrial organic wastewater feeding voltage-resistant reactor containing persistence organic pollutant, adds reactor, and be passed through work by cleaning aluminium powder
Industry CO2Reacted.The granularity of aluminium powder is less than 180 mesh, and every liter of waste water adds aluminium powder 5g~30g.Under ul-trasonic irradiation, machinery
The stirring reaction time be 10min~40min, reaction temperature be 25 DEG C~60 DEG C, CO2Pressure be 0.1MPa~1.0MPa, often
The power of cubic meter waste water input ultrasonic wave is 2kW~8kW.Reacted waste water carries out solid-liquor separation, and the aluminium powder isolated is returned
Return reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjust its pH value to 6.8~8.5, subsequently into
Sedimentation basin precipitates 1h~3h, irregularly extracts sludge out from sedimentation basin and is filtered, and filter cake makees dangerous disposition of solid waste, filter
Liquid returns to sedimentation basin.The supernatant waste water of sedimentation basin send anaerobic reactor.Waste water stops 24h~96h, 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 6h~16h to waste water after anaerobism.It is aerobic
Waste water after treatment enters sedimentation basin and precipitates 1h~3h, irregularly extracts sludge out from sedimentation basin and is filtered, and filter cake is made dangerous
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 filtering tower combined working is filled out
Expect to be activated carbon or porous ceramic grain, be 1.0m~2.0m per thickness degree, gross thickness is 2m~6m.The dominant bacteria of biological filtering tower combined working is
Red pseudomonas in photosynthetic bacteria（Rhodopseudomonas）.The hydraulic load of biological filtering tower combined working is 30 m3/m2.d~90m3/
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, big in waste water after chemical industrial organic wastewater enters aluminum reduction reactor
Molecular organic, particularly persistence organic pollutant（Containing phenyl ring and（Or）The organic matter of heterocycle etc.）Produced by aluminum reduction
Strong reduction free radical effect and destroy, be subsequent biochemical treatment create favorable conditions.It is passed through pressure CO2Purpose be maintain
The suitable pH value of aluminum reduction（2.0~5.0）, the effect for being input into ultrasonic wave is the mass transport process for accelerating reaction.It is useless after reduction
Water milk of lime or other alkaline matters adjust its pH value, to meet the requirement of follow-up anaerobic and aerobic process.Through aforementioned processing
Waste water in anaerobic processes, by the effect of microorganism, larger molecular organicses further become small organic molecule, are follow-up
Biological oxidation creates more favorable condition.Processed by biological oxidation, remaining most of organic matters are removed, while going to denitrogenate phosphorus
Deng pollutant.Waste water finally enters activated carbon or porous ceramic grain biological filtering tower combined working, in the effect 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（Iron-carbon micro-electrolysis, metal powder reduction, Fenton methods etc.）, outstanding advantages of the invention are to adopt
Use CO2Make acidulant instead of now widely used sulfuric acid, do not introduce SO4 2-Ion, essentially eliminates generation H2The material base of S
（Part chemical industrial organic wastewater contains S）, so as to significantly reduce 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；Chemical plant all has boiler, what fuel combustion was produced
CO2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；Waste water energy stabilization after treatment reaches
Mark discharge, with obvious economic benefit and environmental benefit.
