Abstract
Description
Ausgehend von der anaeroben Faulung kommunaler Art in volldurchmischten Reaktoren mit Suspensawachstum wurde in den letzten 10 Jahren Hochleistungssysteme entwickelt. Diese sind optimiert auf die anaerobe Vorreinigung großer Volumina organisch stark belasteter Abwässer der Nahrungs- und Genußmittelindustrie sowie des Agrarbereichs auf CSB-Ablaufwerte von 400-1500 ppm bei relativ kurzer Verweilzeit.Starting from the anaerobic digestion of communal kind in fully mixed reactors with suspension growth was in the developed high-performance systems in the last 10 years. These are organically optimized for the anaerobic pre-cleaning of large volumes highly contaminated waste water from the food and luxury food industry as well as the agricultural sector with COD discharge values of 400-1500 ppm relatively short dwell time.
Zu den neuen Konzeptionen zählen: Kontaktverfahren mit Suspensa- Rückführung; Reaktoren mit Ansiedlungswachstum (Festbettreaktoren, Anaerobfilter, Schwebe- und Fließbettreaktoren, Schleifenreaktoren) &&&& sowie Schlammbettreaktoren (UASB) mit Bakterien-Pelletbildung und interner Phasentrennung. Die Verfahrenskonzepte schließen häufig eine Vorversäuerung bei pH 3,5-6,5 und eine optimale Prozeßtemperatur von 30-33°C sowie Methanisierung bei pH 6,5-7,5 und 33-38°C in Form sog. zweistufiger Verfahren mit ein. Nährstoff/Nährsalzminimum: CSB/N/P = 800/5/1.The new concepts include: Contact procedure with Suspensa- Return; Settlement reactors (fixed bed reactors, Anaerobic filters, floating and fluidized bed reactors, loop reactors) &&&& and sludge bed reactors (UASB) with bacterial pellet formation and internal phase separation. The procedural concepts close often pre-acidification at pH 3.5-6.5 and optimal Process temperature of 30-33 ° C and methanation at pH 6.5-7.5 and 33-38 ° C in the form of so-called two-step processes. Minimum nutrient / nutrient salt: COD / N / P = 800/5/1.
Gemeinsam ist diesen Systemen die Rückhaltung von aktiver Biomasse. Neben der mesophilen Prozeßführung ist auch der anaerobe Abbau im thermophilen Bereich technisch realisiert.What these systems have in common is the retention of active biomass. In addition to the mesophilic process control, anaerobic degradation is also in the thermophilic area technically realized.
Allgemeine Vorzüge dieser "Methangärung" sind:General advantages of this "methane fermentation" are:
- - Realisierung einer hohen CSB-Raumbelastung bis ca. 100 000 mg CSB/l;- Realization of a high COD space load up to approx. 100,000 mg COD / l;
- - kein Energieinput, sondern Energiegewinn in Form von 0,3-0,4 m3 Biogas pro Kilogramm eliminierten CSB entsprechend 1,9-2,6 KWh/kg CSB- No energy input, but energy gain in the form of 0.3-0.4 m 3 biogas per kilogram eliminated COD corresponding to 1.9-2.6 KWh / kg COD
- - nur 3-5% des eliminierten CSB fallen als (weiter zu entsorgender) Überschußschlamm an. Zum Vergleich: 25%-40% bei aeroben Verfahren- only 3-5% of the eliminated COD falls as (to be disposed of) Excess sludge on. For comparison: 25% -40% for aerobic processes
- - Verringerung von Geruchsemissionen.- Reduction of odor emissions.
Der Vorteil der modernen Konzepte liegt in der Entkopplung von Aufenthaltszeit im Reaktor und den relativ langen Generationszeiten der Methanbakterien (siehe oben). Dadurch kann man Aufenthaltszeiten von weniger als einem Tag realisieren und mit aeroben Verfahren unter Verringerung der Betriebskosten konkurrieren.The advantage of modern concepts lies in the decoupling of Residence time in the reactor and the relatively long generation times of methane bacteria (see above). So you can Realize residence times of less than one day and with aerobic process while reducing operating costs compete.
Zur Erreichung der Vorfluterreife des Abwassers wird eine aerobe Stufe nachgeschaltet (anaerob-aerob Behandlung) bzw. eine Einleitung in eine kommunale Kläranlage vorgenommen. Anaerobe Verfahren sind u. a. geeignet für Industriewasser von Zucker-, Stärke-, Hefe-, Pektin-, Carragen-, Kaugummifabriken sowie Betriebe der Obst-, Gemüse- und Kartoffelverwertung sowie Abläufe aus Molkereien, Brauereien, Brennereien, Schlachthöfen und Fleisch- und Fischverarbeitung.To achieve the receiving water maturity of the wastewater, an aerobic Downstream level (anaerobic-aerobic treatment) or one Introduction into a municipal wastewater treatment plant. Anaerobic Procedures are u. a. suitable for industrial water from sugar, Starch, yeast, pectin, carrage, chewing gum factories and factories fruit, vegetable and potato recycling as well as processes Dairies, breweries, distilleries, slaughterhouses and meat and Fish processing.
Großtechnisch wurden bis 1986 weltweit 160 anaerobe Hochleistungssysteme installiert. Davon stehen 20 Anlagen in der Bundesrepublik Deutschland.By 1986, 160 anaerobes had been developed on an industrial scale High performance systems installed. 20 of them are in the Federal Republic of Germany.
Die anaerobe Vorreinigung ist in der Zuckerindustrie und bei Brennereien mit 120 Anlagen am stärksten eingesetzt.Anaerobic pre-cleaning is in the sugar industry and at Distilleries with 120 plants most used.
Der charakteristische Fortschritt der Erfindung gegenüber den oben genannten Reaktortypen besteht in der Anwendung einer gepulsten Strömung und ist in Abb. 1 gezeigt: Auf das durch den Reaktor hindurchströmende Abwasser/Wasser wird über eine Pulspumpe eine Schwingung übertragen.The characteristic progress of the invention over the above-mentioned reactor types consists in the use of a pulsed flow and is shown in Fig. 1: A vibration is transmitted to the waste water / water flowing through the reactor via a pulse pump.
Der Puls begünstigt Transportvorgänge um die Mikroorganismen. Die rückvermischende und durchmischende Bewegung der flüssigen Phase relativ zur schwebenden oder immobilisierten Bakterienzelle führt Nährstoffe des Substrates heran und entstehende Stoffwechselprodukte aus der unmittelbaren Umgebung des Biosystems ab. Der Stoffabbau wird durch das osmotische Gefälle über die Membran zwischen Zellinnern und Umgebung kontrolliert. Daneben wird Kurzschlußströmungen zwischen Onput und Putput entgegengewirkt.The pulse favors transport processes around the microorganisms. The backmixing and mixing movement of the liquid phase leads relative to the floating or immobilized bacterial cell Nutrients of the substrate and arise Metabolic products from the immediate vicinity of the biosystem from. The decomposition of substances is caused by the osmotic gradient across the Controlled membrane between cell interior and environment. Besides short-circuit currents between onput and putput are counteracted.
Die fluiddynamischen Variablen (Pulsfrequenz, Pulsamplitude, Strömungsgeschwindigkeit) ermöglichen die Schaffung großer, sich ständig erneuernder Stoffübergangs - Oberflächen an den aktiven Mikroorganismen - Membranen und begünstigen Ablösung und/oder Austrag von toter Biomasse (Biofilm, Altschlamm, Inertstoff), wodurch auch der Gefahr vonVerstopfungen entgegengewirkt wird. Dies entspricht in der Konsequenz einem größeren aktiven Reaktorvolumen und führt zu einer Erhöhung von Abbauleistung und Gasproduktion.The fluid dynamic variables (pulse frequency, pulse amplitude, Flow rate) allow the creation of large ones constantly renewing mass transfer surfaces on the active Microorganisms - membranes and favor detachment and / or Discharge of dead biomass (biofilm, old sludge, inert material), which also counteracts the risk of constipation. As a consequence, this corresponds to a larger active one Reactor volume and leads to an increase in mining capacity and Gas production.
Das Verfahren und der Reaktor sind in analoger Weise für aerobe Mikroorganismen bei der Denitrifikation (Nitratreduktion unter Bildung von Distickstoffmonoxid und Distickstoff) von Abwasser und Trink- bzw. Betriebswasser und andere biotechnologische Prozesse der Stoffumwandlung anwendbar.The process and reactor are analogous for aerobic Microorganisms in denitrification (nitrate reduction under Formation of nitrous oxide and nitrous oxide) from waste water and Drinking water, process water and other biotechnological processes in the Substance conversion applicable.
