Definitions
- This invention relates to a reactor and a method for anaerobic wastewater treatment.
- Municipal wastewater is comparatively low contaminated with a chemical oxygen demand (COD) of approx. 500 mg / l and is usually treated with aerobic activated sludge processes.
- COD chemical oxygen demand
- UASB Upflow Anaerobic Sludge Blanket
- An internal biomass enrichment takes place in UASB reactors in the form of a developing and very well granulating sludge.
- the microorganisms aggregate into so-called pellets. These are aggregates with a size of approx. 1 to 3 mm.
- the reactors are operated in upflow mode, ie the waste water flows through the reactor from bottom to top.
- the metabolic degradation of organic contaminants creates gases that adhere to the pellets in the form of gas bubbles. As a result, the pellets rise which leads to mixing in the system.
- a separator system is provided in the upper area of the UASB reactor, which serves to retain the pellets in the reactor.
- Another high-performance process uses fixed bed reactors, whereby inert carrier materials as beds, packs or also fixed carrier materials, e.g. in the form of plate-shaped carrier elements, colonized by microorganisms.
- inert carrier materials as beds, packs or also fixed carrier materials, e.g. in the form of plate-shaped carrier elements, colonized by microorganisms.
- Such a reactor is described in patent DE 43 09 779 by the same applicant.
- Very heavily polluted wastewater with COD concentrations of over 80 g / l can be treated in fixed bed reactors.
- a disadvantage of the fixed bed reactor is that the costs are high, especially in the case of high-performance carrier materials.
- fluidized bed reactors are also known in which the biomass is immobilized on a fluidized fixed bed, for example activated carbon or sand, which is swirled in the reactor. This requires a high energy requirement to maintain the fluidized bed, which also results in a high load on the reactors.
- the design of fluidized bed reactors is accordingly technically demanding and complex.
- the invention has for its object to provide a reactor and a method for anaerobic wastewater treatment, which is suitable for heavily polluted wastewater and works with little interference and is comparatively inexpensive.
- the reactor can be cylindrical, other reactor geometries are also possible, e.g. cylindrical arrangements with an elliptical or polygonal base or cuboid arrangements.
- the room in the lower area can hold waste water with microorganism pellets suspended in it.
- the microorganisms develop metabolic gases that adhere to the pellets as bubbles and thereby carry the pellets upwards.
- Bacteria of the Gat- are preferred as microorganisms
- a separator system is preferably arranged in the upper area, which retains microorganisms suspended in the waste water in the reactor.
- the reactor preferably has a recirculation system, which has an extractor for waste water and a feeder for waste water for discharging the flow into the central flow channel.
- the extractor preferably comprises a gap between two plattenar- 125 • term elements and a beginning in the intermediate space conduit has.
- the discharge system for the final discharge of treated wastewater is positioned a little above the extractor of the recirculation system.
- the sepaprator system can be used to separate the gases 135 generated as well as to retain the biomass.
- the separator system preferably has a partition wall at a distance above the upper end of the central flow channel, which covers a large part of the reactor cross section and leaves an outer annular surface free.
- the extractor of the recirculation system is preferably positioned on the top of the partition. In the space above the tapping point of the recirculation system, a flow-calmed zone is created that supports the discharge of treated waste water without biomass discharge, especially since - as mentioned above - it is preferred that the discharge system for the final discharge of treated waste water is one piece is positioned above the extractor of the recirculation system.
- the partition of the separator system preferably runs in some areas non-horizontally and forms a gas collection space in a highest area.
- the partition wall - roughly speaking - runs obliquely outwards downwards and obliquely inwards downwards.
- a first discharge line 165 for gas formed in the reactor preferably begins in the upper region of the reactor.
- a second discharge line for gas formed in the reactor begins in the area of the partition.
- Support elements are provided in the reactor.
- the carrier elements can be designed in the form of plates.
- the carrier elements are preferably arranged parallel to one another.
- the plates can be arranged in packages, the plates being arranged within the packages in the tangential direction of the reactor.
- the support elements are arranged above the space in the lower area, 175 so that the pellets floating upward flow between the plates.
- microorganism growth forms on the support elements. It is preferred that there is a distance of 3-6 cm, preferably 3.5-5.5 cm, between the carrier elements.
- the carrier elements can consist of an inert material with a large surface. They preferably consist of a flow-porous material.
- the carrier elements particularly preferably consist essentially of plastic particles and expanded clay particles combined with one another. Polyethylene particles are preferred, with other plastics being possible.
- 185 gansimes can settle in the pores of the expanded clay and in the pores between the particles and form a film-like or lawn-like growth on the carrier elements.
- the microorganism film is destroyed.
- the microorganisms can quickly get out of the pores of the porous carrier material
- the plates of the support elements can be coated with a variety of microorganisms, e.g. Bacteria to be colonized. It is possible to populate the carrier elements with different species at the same time.
- the carrier elements can be populated with the same species as free floating aggregates or pellets
- the carrier elements can be populated with other species than those which form or form the pellets. This allows the advantages of the UASB method to be combined with the advantage of a greater variety of usable microorganisms.
- the carrier elements can be populated with sessile microorganisms. In particular, they can be populated with the genera Sytrophobacter, Sytrophomas, Methanotrix, Methanosarcina and Methanococcus.
- the inventors have found that the synergy effects (high performance 205 with stable operation) from the combination of a fixed bed reactor and a UASB reactor already occur with a relatively small proportion of carrier plates based on the reactor volume. It is therefore preferred that the proportion of the reactor volume covered with carrier plates is 15 to 40%. The proportion is particularly preferably 20 to 30%.
- a flow deflector is preferably positioned on the wall in the lower region of the reactor. This flow deflector has the task of releasing the wastewater flow from the reactor wall and directing it to the carrier elements in a more uniform manner.
- the reactor can preferably have at least one propulsion jet outlet which ends below the lower end of the central flow channel. This serves to whirl up microorganisms that have settled on the reactor floor.
- the mouth can have a nozzle at its end
- the object of the invention is further achieved by a method for anaerobic wastewater treatment in a reactor in which wastewater to be treated circulates, such that wastewater

- Other reactor geometries are also possible, e.g. cylindrical arrangements with elliptical or
- the reactor housing 1 1 is, as is known from the prior art, essentially made of stainless steel sheets.
- a central tube 20 is formed in the axial direction, which begins a piece from the upper end of the reactor and opens into the lower region 30.
- the central tube 20 is hexagonal in cross section. This hexagonal shape is inexpensive to manufacture and packages with carrier elements 50 can be arranged to match the hexagonal shape. Other geometries are also possible, for example circular or polygonal with a different number of corners.
- the lower region 30 is designed as a space in which the floating microorganisms are present during operation.
- a central region 40 in which plate-shaped carrier elements 50 are arranged in parallel, so that flow paths in the vertical direction are present between these carrier elements.
