Definitions
- the present invention relates to a method for carrying out the biological purification of municipal or similar wastewater with the aid of activated sludge, according to the preamble of claim 1, and a device for carrying out this method.
- European Patent EP 0 851 844 discloses a process for the biological purification of wastewater with the aid of activated sludge, in which the wastewater is first introduced into a ventilatable activated sludge tank and then into a sedimentation tank in which sludge and clear water are separated and after Separation activated sludge is returned to the aeration tank and clear water is withdrawn.
- a stirring phase U Several times a day runs an operating cycle in the sedimentation tank, which has a stirring phase U, a Vorabsetzphase V and a withdrawal phase A, wherein in the stirring phase, the activated sludge is mixed again with the water in the Vorabsetzphase the activated sludge is sedimented and drawn in the withdrawal phase of clear water becomes.
- the purification is carried out in a biological two-basin system - the activated sludge and the sedimentation basin with constant inflow and outgoing discharge.
- the water level rises through the inflow (Aufstautama).
- the claim of this method is that after the pre-settling phase and before the stirring phase sedimented activated sludge is returned to the aeration tank of the "bunker system with Aufstau ist.”
- the stirring phase the contents of the B-basin with that of the SU basin to largely the same dry matter
- Both basins are adjacent to each other and are permanently hydraulically connected in the floor area.
- This object is achieved by a method having the features of claim 1 and a device for carrying out this method.
- the modular system is used in large sewage treatment plants.
- a larger number of modules - consisting of a B-basin and two SU basins (Figs 2 and 3) arranged on the opposite sides of the B-basin - are assembled to form a sewage treatment plant.
- By joining up to 10 modules (possibly even more) creates a very long and narrow B-basin, in which there is a risk that short circuit flows of the thickened activated sludge in the S-phase and the continuously supplied wastewater for cleaning arise.
- One known way to solve these problems is to make the B-tank as a circulation tank.
- One aspect of the invention therefore has the object of solving the recirculation of the thickened activated sludge from the SU tank into the B tank (S phase) so that there is no short-circuit flow.
- the thickened sludge must not enter the SU tank again after entering the B tank, as otherwise the sludge return will fail, the dry substance in the B tank will fall sharply and the cleaning performance will no longer be sufficient.
- the solution to this problem according to this aspect of the invention is that in the B-basin two ventilation fields 1 and 2 (usually fine-bubble ventilation) are arranged at the edges to the SU basins, which can be operated jointly or separately depending on the process , In the pelvic center remains a ventilation-free area (about one third of the tank width).
- Ventilation fields There may also be more than two ventilation fields, e.g. four, six, eight, twelve or sixteen ventilation fields, which preferably each supply one or more modules in pairs.
- the aspect of the invention provides that the wastewater to be purified is supplied with one or more horizontal pipelines which extend in the longitudinal direction of the B basins, are located in the center of the basin at about half the depth of the water and have openings.
- the openings are preferably arranged in such a way that the wastewater can escape horizontally in both directions and a uniform coating of the B basins and modules is possible (FIG. 3).
- both ventilation panels should be operated in the same way (either different air supply or intermittent ventilation). In this way, an optimal mixing of the contents of the B-basin in these phases with good biochemical purification is achieved.
- the present invention may also be used when both SU basins are placed on one side of the B-basin.
- FIGS. 5 and 6 Two devices are shown in FIGS. 5 and 6. It should also be noted that this process is responsible for a large part of the nitrate pollution in the SU basins (endogenous denitrification). The excess sludge is withdrawn from the bottom of the SU basins before the beginning of the S phases. The activated sludge is then thickened.
- Fig. 1 shows the operating cycle for the two SU basins of the embodiment
- Figure 2 is a schematic representation of a treatment plant line of the embodiment, consisting of 8 modules.
- 3a and 3b are respectively a plan view and a vertical section of a module of Figure 2 (S phase) ..;
- FIG. 6 is a clear water outlet with flat slide chain.
- FIG. 1 shows an operating cycle in the two SU tanks SUi and SU2, the time being in the horizontal direction to the right. Further details of the sequence and function of the individual phases have already been discussed above.
- Fig. 2 the plan of a sewage treatment plant, consisting of 8 modules, is shown schematically. One of the modules is highlighted by hatching.
- FIGS. 3a and 3b show a schematic plan view and a vertical section of a module (along a line that runs horizontally through a module in FIG. 2).
- the components 1 and 2 denote the two ventilation fields
- 3 the pipe for supplying the waste water Q to be cleaned
- 4 the openings for uniform coating of the B tank with the waste water Q
- 5 the compressed air lifter for operating the S phase
- 6 the bottom pipes to drain the thickened sludge Qs
- FIGS. 4a and 4b show schematic vertical sections through a B-basin with aerator fields according to the invention.
- FIG. 4 a shows the flow conditions during operation of an aerator field (S-phase); and in Fig. 4b when operating both Belvoiderfeldern (U and V phase).
- Reference numeral 9 designate the flaps of the air lift.
- a system for the clear water outlet which consists of numerous, about 30 cm below the minimum water level and at a distance of about 1.50 m arranged discharge openings about 150 mm, which opened with vertically movable closure plates 14 and can be closed. These closure plates are moved by springs provided with rods 15 and pressed at the same time to the Abpoundöff. The opening and closing is finally by a rotating horizontal shaft 16 which is driven by a motor 17 adapted to the requirements.
