Description
Technical field
A kind of processing method of the wastewater containing phenol and cyanide produced the present invention relates to gas generator.
Background technology
Coal gas is a class widely used fuel in production and life, and it is to be by one in gas generator by coal
Row chemically react and are obtained.During cooled coal gas is prepared, wastewater containing phenol and cyanide is inevitably resulted from(Waste water containing phenol and cyanogen),
If the waste water is directly discharged into environment and will cause severe contamination to environment.The processing method of current wastewater containing phenol and cyanide mainly has biochemistry
Processing method, independent burning method, water-coal-slurry facture processed and it is mixed into drying tower Feedstock treating method.The treatment of biochemistry treatment method
Effect is unstable, relatively costly;Although independent burning method treatment effect is very well, processing cost is very high;Water-coal-slurry facture processed
Coal slurry industry investment it is big, many producers are without this system, it is difficult to implement.It is mixed into drying tower Feedstock treating method, low-temperature zone
A large amount of evaporations, thus make considerable part phenol and cyanogen have neither part nor lot in chemical reaction and enter air.Development cost is low, high treating effect
The processing method of the wastewater containing phenol and cyanide that gas generator is produced has larger practical value.
The content of the invention
The problem of the processing method of the wastewater containing phenol and cyanide produced for current gas generator, the purpose of the present invention is at searching
Reason low cost, the processing method of the wastewater containing phenol and cyanide of the gas generator generation of high treating effect, it is characterised in that coal gas occurs
The wastewater containing phenol and cyanide that stove is produced is filtered, the feeding voltage-resistant reactor after filtering, and cleaning zinc powder is added into reactor, is passed through industry
CO2And reacted under ul-trasonic irradiation.The granularity of zinc powder is less than 180 mesh, and every liter of waste water adds zinc powder 5g~10g.Super
The stirring reaction time is 10min~40min under sound wave effect, and temperature is 25 DEG C~60 DEG C.Every cubic metre of ultrasound of waste water input
Wave power is 2kW~8kW. CO2Pressure be 0.1MPa~1.0MPa.Reacted waste water carries out solid-liquor separation, isolates
Zinc powder Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjust its pH value to 6~8, Ran Houjin
Enter sedimentation basin precipitation 1h~3h, irregularly extract sludge out from sedimentation basin and filtered, filter cake makees dangerous disposition of solid waste,
Filtrate returns to sedimentation basin.The supernatant of sedimentation basin send hydrolysis acidification pool.Waste water normal temperature in hydrolysis acidification pool stops 8h~24h.
Into the treatment of biology aerobic pond normal temperature, the Aerobic Process for Treatment time is 8h~12h to waste water after hydrolysis acidification.Waste water after Aerobic Process for Treatment
1h~3h is precipitated into sedimentation basin, irregularly sludge is extracted out from sedimentation basin and is filtered, filter cake is made at dangerous solid waste
Put, filtrate returns 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 be activated carbon or
Porous ceramic grain, is 1m~2m per thickness degree, and gross thickness is 2m~6m.The dominant bacteria of biological filtering tower combined working is the red vacation in photosynthetic bacteria
Monad(Rhodopseudomonas).The hydraulic load of biological filtering tower combined working is 30 m3/m2.d~100m3/m2.d.Biological filtering tower combined working
Standard water discharge is discharged or reuse.
The object of the present invention is achieved like this:Waste water enters pressure-resistant Zinc Powder Reduction device, and the macromolecular in waste water has
Machine thing, particularly persistence organic pollutant(Organic matter containing phenyl ring, heterocycle)The strong reduction freedom produced by zinc powder reduction
The effect of base and destroy, be subsequent biochemical treatment create favorable conditions.It is passed through pressure CO2Purpose be maintain zinc powder reduction it is suitable
PH value(2.0~5.0);The effect for being input into ultrasonic wave is to speed up the mass transport process of reduction reaction.Waste water lime after reduction
Breast or other alkaline matters adjust its pH, to meet sequential hydrolysis acidifying and the requirement of aerobic process.Through the waste water of aforementioned processing
In Hydrolysis Acidification, by the effect of microorganism, larger molecular organicses further become small organic molecule, are follow-up life
More favorable condition is created in thing oxidation.Processed by biological oxidation, remaining most of organic matters are removed.Waste water finally enters work
Property charcoal or porous ceramic grain biological filtering tower combined working, in the presence of microorganism, particularly red pseudomonas, further organics removal is protected
Waste water stably reaching standard discharge after card treatment.
Relative to existing method, outstanding advantages of the invention are to use CO2It is acidified instead of now widely used sulfuric acid
Agent, does not introduce SO4 2-Ion, essentially eliminates generation H2The material base of S(Contain a small amount of S in wastewater containing phenol and cyanide), so as to subtract significantly
Light H2The pollution of S, while it also avoid SO4 2-To hydrolysis acidification and it is aerobic during microorganism inhibitory action, greatly improve
The efficiency of biological treatment;The producer of gas generator is had, subsequent combustion device, CO needed for the present invention are had mostly2Can be from combustion
It is isolated in the waste gas that burning is produced, processing cost can be not only reduced, and carbon emission can be reduced;Waste water energy after treatment is steady
Determine qualified discharge, and be adapted to focusing on for the wastewater containing phenol and cyanide that remaining many gas generators are produced, investment reduction, with obvious
Economic benefit and environmental benefit.
