It is an advantage of the current invention that
1, employing Fenton reagent is as catalytic oxidation reagent, utilize Fenton reaction settling basin high treating effect, owing to the essence of Fenton oxidation technical finesse organic pollution is-OH and organic pollution effect, the essence of free-radical oxidation degradation of organic substances is that-OH propagates radical chain reaction by approach such as electron transfers, part attack Organic substance RH captures hydrogen, generation free radical R-, R-are degraded to small organic molecule further or mineralising is CO2With the inorganic matter such as HO2, part is reacted with Organic substance and is C C key or C H key is fissioned, and is finally degraded to harmless object。It addition, the nascent state Fe (OH) 3 that reaction generates has good absorption, cohesion function, residual contamination substrate concentration in waste water, raising water outlet quality can be reduced further。
2, efficient I and II anaerobic pond (7,8) and UASB (upflow anaerobic sludge blanket process) formula is adopted to process technique, this technique dilutes rapidly reduction wastewater biological toxicity, ring will be carried out brokenly containing phenyl ring organic pollution by facultative and anaerobe depth hydrolysis's function simultaneously, be beneficial to the carrying out of aerobic biochemical reaction。Utilize multinomial jet mixer to be quickly sufficiently mixed with the waste water in cell body by waste water with very low energy consumption, the continuous uniform of whole cell body can be kept to stir simultaneously, make full use of cell body space。There is energy consumption low, the advantage that organic loading is high, and COD volumetric loading is generally 5-10KgCOD/m2.d, strict control pH value and temperature can significantly remove COD material, reduce the load of follow-up Aerobic Process for Treatment, management and maintenance all fairly simple。
3, oxic activated sludge process is adopted: catalytic oxidation and SBR method。This technique is domestic is generally adopted contact oxidation method, and the efficiency comparison of its filler adopted general adsorption activity mud is low, and mud easily comes off, and causes that effluent quality is muddy, and the settling efficiency of mud is poor。According to similar experience, the treatment effect of single biochemical process p-nitrophenyl waste water is not enough to reach qualified discharge, therefore needs series winding to be processed technique with activated sludge process by complementary biomembrane biochemistry。There are one-level, two grades of Aerobic Ponds (7,8) after the contact-oxidation pool 10 of the present invention, in order to continuous way operating, adopt efficient absorption filler, be beneficial to the attachment of a large amount of activated sludge, growth。SBR pond is batch-type operating, utilizes aeration by the Organic substance in a large amount of activated sludge absorption degrading waste waters in pond, and when aeration stops, activated sludge settles in a large number, and the supernatant is skimmed hydrophone and led outflow system, and lower floor's mud is retained when。
Oxygenic aeration is carried out to contact-oxidation pool 10,11, two grades of Aerobic Ponds 12 of one-level Aerobic Pond and SBR pond 13 through aerator, the oxygen content in water is made to reach about 2-4ppm, (COD is about 100ppm, and temperature is at 32-34 degree, and pH value is at 7-8 to be received from the waste water of anaerobic system, colourity more than 20 times), after treatment, COD is reduced to about 30ppm, and colourity is below 20 times, Nitrobenzol and aniline material are all at below 0.1ppm, far better than relevant national standard。
Contact-oxidation pool 10, Aerobic Pond, SBR pond 12 major function are that Organic Pollutants in Wastewater is converted into carbon dioxide and water by the vital movement making good use of oxygen animalcule group, reach the purpose of purification of water quality。Similar engineering experience proves, the maximum difficult point of nitrobenzene waste water biochemical treatment is exactly the maintenance of activated sludge and overcoming of bio-toxicity, and this kind of wastewater treatment equipment, by regular additional a small amount of broad spectrum of activity mud and organic nutrient aganic nutrient agent, effectively solves an above-mentioned difficult problem。Meanwhile, the present invention can adopt efficient jet aerator, can be effectively improved the settling property of activated sludge while significantly reducing energy consumption (not using aerator)。
4, unique mixing biochemistry strain is used。Owing to Nitrobenzol and aniline belong to the organic arene material being difficult to degrade, and possibly together with the phenols of more difficult degradation in waste water, thiophene-based material, intractability is very big, so the present invention is at contact-oxidation pool 10, one-level Aerobic Pond 11, two grades of Aerobic Ponds 12, SBR pond 13 is each through the organic pollution in aerobic microbiological group's Decomposition Wastewater, aerobic microbiological group includes pseudomonas, solve phenol pole hair bacillus, micrococcus, campanularian class sessile form ciliate, the type ciliate of crawling is J fibre worm such as, swallow the metazoa wheel animalcule of the mud that is scattered and solid wheel animalcule, adopt the mixed bacteria through good domestication and screening。This strain to multiple dyestuff intermediate such as chloronitrobenzene, aniline, Nitrobenzol, phenol, in (neighbour) production process such as aminoanisole, cyclohexanone produce industrial wastewater have uniqueness adaptability。Through the domestication of this technique and the microorganism cultivated, the toleration of above-mentioned substance is good, mobility is strong, and degradation rate is higher, and effluent quality is highly stable。Handling rate is high, and clearance reaches more than 99%, and every effluent index can reach GB8978-1996 first discharge standard, and effluent color dilution, lower than 20 times, operates steadily, high treating effect。
5, highly effective sludge flocculation sediment mix reagent is adopted。When processing waste water, settle firstly the need of by a large amount of mud in waste water, realize efficiently separating of mud and clear water, adopt efficient sludge flocculation precipitation reagent, this sludge flocculation precipitation reagent includes organic high polymer polyacrylamide flocculant and iron salt, add when controlling waste water pH value well, it is greatly accelerated sedimentation velocity and the effect of settling of mud, making to reduce to below 5000ppm into the sludge content in the waste water of biochemical system, the operation for subsequent wastewater treatment system is laid a good foundation。
Being combined by above method, good waste water treatment effect, every effluent index can reach GB8978-1996 first discharge standard。
The above, be only the specific embodiment of the present invention, but protection scope of the present invention be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention。Therefore, protection scope of the present invention should be as the criterion with claims protection defined。
