Abstract

The processing method of the synthesis pharmaceutical organic wastewater that the present invention is introduced includes CO2Pressurize and the operation such as the reduction of MnZn composite powder, 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

The processing method of synthesis pharmaceutical organic wastewater
Technical field
The present invention relates to a kind of processing method of synthesis pharmaceutical organic wastewater.
Background technology
Medicine is the necessity for ensureing the mankind and animals and plants health, and the Pollutants in Wastewater COD concentration that its production is produced is high, Complicated component, intractability is big.If the waste water is not processed is directly discharged into environment, severe contamination will be caused to environment.Synthesis at present The processing method of pharmacy organic wastewater mainly has physical-chemical process, chemical method, biochemical process, these methods otherwise processing cost Height, otherwise it is difficult to stably reaching standard discharge.Development cost is low, the processing method of the synthesis pharmaceutical organic wastewater of energy stably reaching standard discharge With larger practical value.
The content of the invention
For the problem of current synthesis pharmaceutical method for processing organic wastewater, the purpose of the present invention is that searching processing cost is low, The processing method of the synthesis pharmaceutical organic wastewater of energy stably reaching standard discharge, it is characterised in that pH value is more than 5.0, and adjusted pond Synthesis pharmaceutical organic wastewater feeding voltage-resistant reactor after regulation.Cleaning MnZn composite powder is added into reactor, and is passed through industry CO2Reacted.The granularity of MnZn composite powder is less than 180 mesh, and every liter of waste water adds MnZn composite powder 5g~30g.MnZn is combined The content of any metal is not less than 5% in powder.Mechanical agitation simultaneously reacts 10min~40min under ul-trasonic irradiation.Reaction temperature It is 25 DEG C~60 DEG C.CO2Pressure be 0.1MPa~1.0MPa.Every cubic metre of ultrasonic power of waste water of input be 2kW~ 8kW.Reacted waste water carries out solid-liquor separation, the MnZn composite powder isolated（The content of any one metal therein is unrestricted System）Returning reactor.Waste water milk of lime or other alkaline matters after solid-liquor separation adjust its pH value to 6.8~8.5, then 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 sedimentation basin.The supernatant of sedimentation basin send anaerobic reactor.Waste water stops 24h~120h in anaerobic reactor, detests Oxygen temperature 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. Waste water after Aerobic Process for 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 Filler 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 It is the red pseudomonas in photosynthetic bacteria to plant（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, and persistence organic pollutant is typically contained in synthesis pharmaceutical organic wastewater （Organic pollution containing phenyl ring, heterocycle）.After the waste water enters MnZn composite powder reactor, the larger molecular organicses in waste water, Particularly persistence organic pollutant reduces the effect of the strong reduction free radical for producing and destroys by MnZn composite powder, is follow-up Biochemical treatment creates favorable conditions.It is passed through pressure CO2Purpose be to maintain MnZn composite powder to reduce suitable pH value（2.0~ 5.0）.It is the mass transport process for accelerating reaction using the effect of ultrasonic wave.Waste water milk of lime or other alkaline matters after reduction Its pH value is adjusted, to meet the requirement of follow-up anaerobic and aerobic process.Through the waste water of aforementioned processing in anaerobic processes, by micro- Biological effect, larger molecular organicses further become small organic molecule, are that more favorable condition is created in subsequent bio oxidation.It is logical Biological oxidation treatment is crossed, remaining most of organic matters are removed, while going to denitrogenate the pollutants such as phosphorus.Waste water finally enters activity Charcoal or porous ceramic grain biological filtering tower combined working, in the presence of microorganism, particularly red pseudomonas, further organics removal and nitrogen phosphorus Deng pollutant, it is ensured that the waste water stably reaching standard discharge after treatment.
Relative to existing method（Zinc carbon micro-electrolysis, metal powder reduction, composite metal powder reduction etc.）, protrusion of the invention is excellent Point is to use CO2Make acidulant instead of now widely used sulfuric acid, do not introduce SO4 2-Ion, essentially eliminates generation H2The thing of S Matter basis（Partially synthetic pharmacy waste water contains S）, so as to significantly reduce 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 combustion are all had in synthesis pharmaceutical factory Burn the CO for producing2Waste gas can make full use of, and can not only reduce processing cost, and can reduce carbon emission；Waste water after treatment Energy stably reaching standard discharge, with obvious economic benefit and environmental benefit.
