Description
Technical field
The present invention relates to a kind of treatment facility of waste water, especially relate to a kind of upflow anaerobic sludge blanket reactor of handling easy acidifying organic waste water.
Background technology
The anaerobic biological treatment of waste water is that anaerobism and aerobic-anaerobic microbe are methane and carbonic acid gas process with the various organic matter transformation in the waste water under oxygen free condition.Anaerobic biological reactor have handle organic loading height, sludge yield low, to worm's ovum and viral removal effect methane good, output can be used as energy utilization, need not aeration and add nutrition, working cost is low, advantages such as convenient management ([1] He Yanling. the anaerobic biological treatment of waste water [M]. Beijing: China Light Industry Press, 1998,3-53; [2] Chen Jian. Environmental Biotechnology [M]. Beijing: China Light Industry Press, 1990,23-100).Inferior positions such as it is big also to exist reactor volume simultaneously, and start-up period is long.
Up-flow anaerobic sludge blanket (Upflow Anaerobic Sludge Bed is called for short UASB) reactor is a kind of efficient anaerobe reactor by Dutch's invention.Reactor is made up of reaction zone, settling region, air chamber three parts.The bottom is the higher sludge blanket of concentration, is also referred to as Sludge Bed, is the lower suspended sludge layer of concentration on Sludge Bed top, usually sludge blanket and suspended layer is referred to as reaction zone.Be provided with the gas, liquid, solid triphase separator on reaction zone top.Waste water enters from Sludge Bed bottom, mixes contact with mud in the bed, and organism is decomposed by anaerobe and produces biogas, the biogas bubble in uphill process constantly coalescence grow up gradually, under stronger stirring, make Sludge Bed middle and upper part formation suspended sludge layer.Suspended sludge forms particulate state gradually under the shearing action of gas, water.Gas, water, mud mixed solution are in triphase separator, and the biogas bubble comes together in the middle part air chamber and discharges from the top, and supernatant liquor is discharged from top in sidepiece solid-liquid separation chamber, and mud is back to reaction zone from the bottom.By the control upflow velocity, a large amount of mud is stranded in the reaction zone, to keep higher sludge concentration ([3] G.Lettinga, A.F.M.vanVelsen, S.W.Hobma.Use of Upflow Sludge Blanket (USB) Reactor Concept for BiologicalWastewater Treatment, Especially for Anaerobic Treatment[J] .Biotech.Bioeng, 1980,2:699-705).
Because anaerobion propagation slowly; the granulating speed of mud is low; thereby the start-up period that causes the UASB reactor is grown (approximately needing for 6～August) ([4] K.H.Harada, A.Ohashi.Granulation and sludge retainment duringStart-up of a Thermophilic UASB Reactor[J]).Many studies show that; by an amount of adding the in mud as activated carbon particle ([5] all rules; Wang Baoquan; Yu Panchi. add the research [J] that granulated active carbon is accelerated UASB reactor endoparticle process. Chinese water supply and drainage; 1996; 12 (5): 16-19); hard silico-calcium fiber grain ([6] Han Jianhong; Ni Wen; the river writing brush. add of the influence [J] of hard silico-calcium fiber grain to the UASB cold operation. Chinese water supply and drainage; 2003,19 (10): 14-17) wait inert particulate, make it to become the core carrier that forms granule sludge; it is long-pending in the richness on its surface to accelerate bacterium, improves the formation speed of granule sludge.([7] Ceng Jinying such as Ceng Jinying; Yang Renbin; Wu Genyi. do the feasibility study [J] that carrier is cultivated granule sludge with the wheat bran fiber. environmental science and technology; 2006; 29 (10): 17-20) in anaerobic reactor, add the wheat bran fiber as the carrier of cultivating granule sludge; quickened the granulating process of mud, and the active height of the granule sludge that forms and settleability are good, have shortened the start time of reactor.

Beijing: China Light Industry Press, 1998,3-53).Basicity in the proposal reactions devices such as Tu Baohua must be greater than 1000mg/L, with keep pH value level ([8] Tu Baohua, Wang Jianfang, the cultivation [J] of granule sludge in the Zhang Yanqiu .UASB reactor. pollution prevention technique, 2003,16 (3): 65-67).In order to guarantee to be fit to the pH condition of methanogen growth, generally be to keep the carbonate buffer system of inside reactor by taking to add carbonate and supercarbonate.Consider element and multiple amino acids ([9] Dong Xiaowei of containing abundant lime carbonate and trace in the oyster shells, Jiang Guoliang, Li Lide, Deng. the progress [J] of oyster comprehensive utilization. ocean science, 2004,28 (4): 62-65), if an amount of oyster shells particle is added in the UASB reactor as carrier, particularly reactor the unloading phase, the oyster shells particle can play initial stage mud nucleus effect, utilize the character of particle surface, make the rapid enrichment that the bacterium that is easy to form granule sludge can be on particle surface, promote the formation of granule sludge; Simultaneously, the lime carbonate of oyster shells can dissolve gradually along with the acidifying process of waste water, can be buffer system and replenishes basicity, pH value in the UASB reactor is satisfied be fit to the methanogen growth conditions, is beneficial to the raising of methanogenesis activity and stablizes; Secondly, trace element and amino acid satisfy the nutritional requirement of anaerobic bacterium growing multiplication, can promote the metabolism of anaerobic bacterium.After the granule sludge that forms comes to the ripening period, the oyster shells particulate adds and only plays the alkalinity regulator effect, dissolving gradually under solutions of weak acidity, very little ([9] Dong Xiaowei of useful volume influence to reactor, Jiang Guoliang, Li Lide, etc. the progress [J] of oyster comprehensive utilization. ocean science, 2004,28 (4): 62-65; [10] E.P.A.Vanlangerak, H.Ramaekers, G.Lettinga.Impact of location of CaCO
3Precipitation on the development of intact anaerobic sludge[J] .Wat.Res., 2000,34 (2): 447-446).The oyster shells particle is to be raw material with the discarded oyster shells of mariculture, and cheapness is easily processed, and it utilizes and can solve the influence problem of discarded oyster shells to the Coastal environments health, has economy and society benefit doulbe-sides' victory effect.

Fig. 6～8 reflect that into water COD concentration is respectively 700,900,1200 and 1500mg/L (abbreviate stage A as, B, C, D), oyster shells particle addition is respectively 1.5,2.0, and 2.5 and 3.2g/d, the hydraulic detention time of water flowing operation is 5h continuously, and oyster shells adds reactor (A) and compares with the running condition of not adding control reactor (B).As can be seen, when the water inlet COD of stage A was 700mg/L, reactor (A) was identical with the pH variation tendency of (B) water outlet, and pH drops to 7.0 after rising to 7.4 rapidly from 6.6, and water outlet COD drops to 100mg/L from 300mg/L, and the variation of basicity is less.The water flowing initial stage can be observed gas production rate and obviously descends, and illustrates that the methanogenesis activity of mud needs domestication process ([12] E.P.A.Vanlangerak, H.Ramaekers, a G.Lettinga.Impact of location of CaCO
3Precipitation on the development of intactanaerobic).When the water inlet COD of stage B was 900mg/L, organic loading was brought up to 4.3kg glucose/m by 3.4kg
3D, and this moment, anaerobic grain sludge did not form as yet, the impact-resistant ability of sludge acclimatization stage anaerobic sludge is strong not enough, the active recovery of microorganism self and to ([11] the Wang Xinhua Guan Xi Jun that meets the needs of for some time of water quality, Xu Shijie, Deng. waterpower circulation UASB reactor for treatment citric acid wastewater [J]. water technology, 2006,32 (11): 61-65), cause between 6～8d two reactor water outlet pH values to reduce to 6.7 and 6.6 by 7.0 respectively therefrom, mud begins to adapt to gradually this COD concentration afterwards, and the methanobacteria activity is recovered gradually, and reactor (A) and water outlet pH (B) get back to more than 6.8, average basicity is respectively 270mg/L and 200mg/L, and basicity has significant difference.When stage C water inlet COD was 1200mg/L, reactor (A) water outlet pH value rose to 7.4 by 7.0, and the pH of reactor (B) changes not quite 6.8～7.0; Reactor (A) water outlet COD rises to maximum 500mg/L rapidly between 18～22d, then drop to 200mg/L gradually; Because water inlet COD concentration is higher, the gas production rate of finding reactor this moment has improved about 1.5 times and (has been about 268mL/h), and the aerogenesis speed of reactor has been accelerated in organic increase in the water inlet as can be known, and promptly the methanobacteria activity of mud is improved.The Sludge Bed thickness of observing reactor (B) in the later stage can directly observe granule sludge in the reactor (A) less than reactor (A), and the granular sludge process that reactor (A) be described is faster than the reactor (B) that contrasts.When 36d, find that the physical strength and the settling property of reactor (A) granule sludge is all good, grain diameter is about 0.3～2.0mm, shows that granule sludge is mature on the whole.When stage D water inlet COD was upgraded to 1500mg/L, two reactor water outlet pH value stabilizations were 7.0～7.4; Reactor (A) water outlet COD is stabilized in 200mg/L, and reactor (B) the water outlet COD of contrast is raised to 500mg/L rapidly, anti-load impact ability strong ([12] E.P.A.Vanlangerak, H.Ramaekers, the G.Lettinga.Impact of location of CaCO of reactor (A) are described
3Precipitation on the development of intact anaerobic; [13] Cao Gang, Xu Xiangyang, Feng Xiaoshan. basicity is to the influence [J] of UASB granular sludge. Chinese water supply and drainage, 2002,18 (8): 13-16).Reactor (A) is respectively 590mg/L and 450mg/L with (B) the average basicity of water outlet, and the basicity difference obviously increases, and meeting the oyster shells addition increases the basicity amount that can replenish gradually.Granule sludge in the reactor that contrasts when 44d (B) is also ripe gradually.The reactor (A) that oyster shells adds is respectively 76d and 84d with the start-up period of the not interpolation reactor (B) of contrast, and the oyster shells interpolation has been shortened about 10% the reactor start-up time as can be known.
Fig. 9 has reflected that initial pH value is 6 o'clock oyster shells particulate dissolution characteristics.As can be seen, oyster shells is the dissolution rate maximum in initial 2min, reaches 7.1mg Ca
2+/ (Lmin), the basicity that 17.8mg/ (Lmin) can be provided is (with CaCO
3Meter).Along with the carrying out of reaction, the pH value of solution rises gradually, and the dissolution rate of oyster shells reduces gradually, and the basicity deliverability descends gradually, has reached balance, the Ca in the solution when 60min
2+Concentration is 33.5mg/L.
