Embodiment 6
Present embodiment is take erythromycin wastewater as processing object.
The concrete water quality situation of erythromycin wastewater is as follows:
1) high-concentration waste water
High-concentration waste water comprises the erythromycin mother liquor, reclaims solvent waste liquid and Recycling of waste liquid, and COD concentration is up to 800000mg/L, and colourity is dark.Contain a large amount of organic solvents such as methyl alcohol, diethylamine hydrochloride, rhodanate, sulphur red drop hydrolysis products etc. in the waste water to the organic matter of Antimicrobial effect, contain extremely toxic substance SCN-in such waste water simultaneously, its mean concentration is up to more than the 3500mg/L.
2) bacterium slag filtrate
The fermentation liquor pretreatment workshop section dense water of bacterium slag is actual to be that the fermentation mixed liquor is through pretreated bacterium slag.Bacterium slag solid content 3%-4%, COD concentration contains a small amount of residual erythrocin fermentation mycelium up to 20 ~ 300,000 mg/L, and smell is smelly, is not the suitable sewage disposal system that directly enters.Usually, the bacterium slag should be first separates through horizontal screw centrifuge that to obtain moisture content be that about 80% solid bacterium slag and solid content are 1% filtrate, and COD concentration can be down to 50000mg/L.
3) dehydration salt solution
Dehydration salt solution comes from the effluent brine that extracts the post, and COD is 20000mg/L, and colourity is dark, and salt content is up to tens0000.
4) low concentration wastewater
What low concentration wastewater derived from that zymotic fluid cultivates the workshop sections such as the cleaning of evaporator water of section and extraction washes film water and water-dialyzing, and pollution factor mainly is less fermentation residue and colloidal type suspension in the waste water, and COD concentration is generally about 3000mg/L, suitable biochemical treatment.
For the characteristics of erythromycin wastewater, we work out treatment technology and technique according to following two basic principles:
A, the shunting of removing contamination, separation are administered
The characteristics different according to the contaminated wastewater factor adopt first different pretreatment modes to process separately, reach at last a certain indication range after, mixed processing again.
B, first materialization, rear biochemistry
SCN-considerably beyond the biochemical system tolerance range of 100mg/L, can't directly carry out biochemical treatment up to more than the 3500mg/L in the high-concentration waste water.Even with the low concentration wastewater mixed processing, SCN-understands the severe inhibition growth of microorganism equally also up to more than the 400mg/L, greatly reduces the biochemical system treatment effeciency.Residual erythrocin, erythromycin bacterium and biology enzyme can suppress or kill microorganisms in the high-concentration waste water simultaneously.
In addition, high-concentration waste water COD is up to 80,000 mg/L, and so high pollutional load enters biochemical system and wants up to standardly, and its capital expenditure and operating cost all military order enterprise can't be born.Therefore the materialization technology of economical and efficient must consideration be selected first in the processing of high-concentration waste water, removes most SCN-and residual erythrocin, erythromycin bacterium and biology enzyme, then processes with more economical biochemical technology again, and guarantee Systems balanth like this moves.
And do not contain SCN-in the bacterium slag filtrate, so bacterium slag filtrate need not passed through the electrocatalytic oxidation metallization processes.Major pollutants are protein, starch, carbohydrate suspension and the erythromycin bacterium filament of part fermentation residue and a large amount of colloidals in the bacterium slag filtrate, and COD is up to 50,000 mg/L.Therefore, bacterium slag filtrate should enter the biochemical system processing through preliminary treatment ability ability first equally.
Concrete treatment process as shown in Figure 1.As shown in Figure 1, the main handling procedure of waste water is as follows in the present embodiment.
1, the technique of pretreatment of High Concentration Wastewater
Multi-dimensional electro-catalytic oxidation and membrane separation process are adopted in preliminary treatment for high-concentration waste water.And the multi-dimensional electro-catalytic oxidizing process than membrane separation process in capital expenditure, operating cost has superiority on the treatment effect.
The multi-dimensional electro-catalytic oxidation is the high-level oxidation technology that the advantage with little electrolysis and two kinds of reactors of electro-catalysis unites two into one, the organic wastewater of the high concentration of the conglomeraties such as applicable chemical pharmaceutical, high chroma, high toxicity, high salinity, bio-refractory.Especially to difficult for biological degradation such as benzene homologues class, halogenated hydrocarbon, multiring aromatic hydrocarbon, long chain alkane class, heterocyclic compound, total cyanogen, cyanide ion, thiocyanate ions, the pollutant of the toxic property of microorganism and inhibition is had very good treatment effect.
The multi-dimensional electro-catalytic oxidation reaction is based on the electrochemical techniques principle, the strong oxidic particle hydroxyl radical free radical OH that hydrogen peroxide generates in the electrolytic catalysis course of reaction, with pollutant in the waste water without chain reaction selectively occurs fast, carry out oxidative degradation.
The generative process of hydroxyl radical free radical:
Hydroxyl radical free radical be oxidisability only this is in the strong oxidizing property material of fluorine, the organic matter that it has an inhibition to microorganism in oxidation simultaneously also can oxidation poisonous and harmful inorganic matter, as: cyanide, rhodanide, hydrogen sulfide etc. convert it into nontoxic material.
According to the actual production test, COD is 80000mg/L before the high-concentration waste water treatment, and SCN-is 3500mg/L.After the multi-dimensional electro-catalytic oxidation, about 60000 mg/L of COD, clearance is more than 20%, and SCN-is less than 700 mg/L, and clearance is greater than 80%.
2, bacterium slag filtrate pretreating process
Bacterium slag filtrate is that the dense water of fermentation liquor pretreatment separates through horizontal screw centrifuge that to obtain solid content be 1% waste water.The protein, starch, the carbohydrate suspension that contain part fermentation residue and a large amount of colloidals in the bacterium slag filtrate, COD can be up to 50,000 ~ 80,000 mg/L.
Because nutritious characteristics in the high COD of bacterium slag filtrate, high suspended matter, the waste water, reach with waste water and fall COD, the suspension in the waste water that thoroughly liquefies so bacterium slag filtrate can be carried out the anaerobic digestion preliminary treatment.According to bacterium slag filtrate verification experimental verification, the cycle of bacterium slag filtrate anaerobic fermentation is 20 days, and water outlet COD can be down to about 15000mg/L after the anaerobic digestion of bacterium slag filtrate, and most suspended substances is all thoroughly liquefied in the waste water.Therefore, need independent design bacterium slag filtrate anaerobic digestion pretreatment section to subdue most COD and SS in the waste water for bacterium slag filtrate, alleviate follow-up pollutional load.
According to the actual production test, COD was 50000mg/L before bacterium slag filtrate was processed.Through behind the anaerobic fermentation, COD is 18000mg/L, and clearance is 64%.
3, pretreating process after high-concentration waste water mixes with bacterium slag filtrate
High-concentration waste water and bacterium slag filtrate respectively through behind the independently pretreating process separately in this mixing, the ammonia nitrogen mean concentration is up to more than the 1000mg/L in the composite waste, its concentration has surpassed biochemical tolerance range.Select LX catalytic oxidation technology to remove ammonia nitrogen concentration in the waste water, the inhibitory action of eliminating the how follow-up biochemical system of ammonia nitrogen is the main purpose of this workshop section.
The course of reaction of LX catalytic oxidation technology is: regulate the mixed liquor of high-concentration waste water and bacterium slag filtrate for alkalescence, please it is passed in the reactor that catalyst C is housed, simultaneously NaClO and bleaching powder are added in the reactor.Under the effect of catalyst C, mixed liquor and NaClO and bleaching powder can react and generate the material with superpower oxidisability, thereby cause and the propagation radical chain reaction, accelerate the oxidation of organic matter and reducing substances, produce efficient catalysed oxidn, can and contain the Toxic Catalytic Oxygen such as N, CN, S with the organic matter in the waste water and change into NO

According to the actual production test, COD was 40000 ~ 45000mg/L before high-concentration waste water and bacterium slag filtrate mixed liquor were processed, NH
3-N is 1200mg/L.Behind the LX catalytic oxidation, COD is about 35000mg/L, clearance about 10%; NH
3The about 600 mg/L clearances about 50% of-N.
4, comprehensive effluent disposal technology
High-concentration waste water and bacterium slag wastewater preprocessing process have solved that hazardous contaminant has also solved high ammonia nitrogen to the inhibitory action of microorganism simultaneously to microorganism killing and inhibitory action in the waste water.Therefore, the technique of comprehensive wastewater is actual in adopting waste water treatment technique---shallow air-floatation+hydrolysis acidification+IC anaerobism+A/O anoxic/aerobic+advanced oxidation+bio-contact oxidation according to routine and engineering application.
The technique of the present comparative maturity of anaerobe technology has the techniques such as UASB anaerobism, ABR anaerobism, IC anaerobism, and wherein the IC anaerobism is present the most a kind of technique of economical and efficient.The unsurpassable advantages of other anaerobic techniques such as the IC anaerobic technique has the volumetric loading height, capacity of resisting impact load is strong, operating cost is low, the COD clearance high, start-up period is short, so the IC anaerobic technique is first-selected.
The selection of aerobe treatment technology is particularly important, and is low in conjunction with the erythromycin wastewater carbon-nitrogen ratio, the water quality characteristics that ammonia nitrogen concentration is high, the aerobic A/O biological denitrification process of selecting.The A/O biological denitrification process is the comprehensive of conventional activated sludge process, bio-digestion and anti-digestion process, and biological tank is divided into anoxic section, aerobic section by the layout of aerator, return flow channel.In this technological process, BOD5, SS and will be removed one by one with the nitrogen that various forms exists.In the activated sludge of A/O biological denitrification system, flora mainly is comprised of nitrifier and denitrifying bacterium.At aerobic section, the ammonia nitrogen that the ammonia nitrogen during nitrobacteria will become a mandarin and organic nitrogen ammonification become by the biological nitration effect, changes into nitrate; In the anoxic section, the nitrate that denitrifying bacteria is brought interior backflow into changes into nitrogen and escapes in the atmosphere by biological denitrification, thereby reaches the purpose of denitrogenation.
Poor for enterprise's factory effluent biodegradabilities such as chemical industry, pharmacy, one-level outputted aerobic water BOD is extremely low and COD only can process the present situation to 400 ~ 500mg/L, the high-level oxidation technology that the inventor takes to be suitable for after the biochemical treatment is processed, namely in waste water, add hydrogen peroxide and ferrous sulfate, make to be difficult to the biochemical large molecule of ring-type in the waste water or long-chain molecule moment is become biodegradable organic matter by the open loop chain rupture.Through verification experimental verification, the A/O outputted aerobic water of thiocyanic acid waste water is through after this technology oxidation, and B/C can by being increased to about 0.4 close to zero of former water, then can be down to about 120mg/L through secondary Aerobic Process for Treatment water outlet COD.
Test according to actual production, comprehensive wastewater COD is 12000mg/L, be reduced to 10000mg/L through COD behind the shallow air-floatation, be reduced to 7500mg/L through COD behind the hydrolysis acidification, be reduced to 1500mg/L through COD behind the IC anaerobic reaction, COD is reduced to 500mg/L after aerobic through A/O, is reduced to 300 ~ 350mg/L through COD behind the advanced oxidation, is reduced to below the 120mg/L through COD behind the bio-contact oxidation.
Advanced the erythromycin wastewater that this method is processed, discharging reaches the industry first discharge standard.
