Description

Technical area

The present invention relates to the field of purification of wastewater, especially caused by rain and thawing snow by means of adsorption of pollutants.

State of the art

Metals are for the outer lining of buildings long known and recently used increasingly materials. Due to environmental influences can but for most materials used, such as copper and / or zinc sheets, a removal of corresponding ions resp. their entry into the wastewater leads to critical concentrations.

In existing pilot plants for the treatment of heavy metal-containing roof and facade wastewater rain and condensation water is collected in a gutter and passed through a drain pipe first in a particle or particle filter in which leaves and larger particles sieved and / or sedimented. The supernatant above the sediment is passed over an overflow into a retention volume in which further sedimentation takes place. The retention volume is divided into a usable retention volume, the proportion that can be supplied to the adsorber, and a dead volume that can serve as a sedimentation zone in which particles and leaves can remain. The adsorber is filled with an adsorbent suitable for the adsorption of the desired substances and above this adsorbent, in the region of the water inlet from the retention volume, finished with a gravel layer serving for the distribution of water and the impact protection. On the side facing away from the inflow of the adsorbent, i. At the bottom, the purified water is drained away, either by discharge into the sewerage system or by feeding it into a roof water supply, receiving water or infiltration. In the event that so large amounts of water accumulate that the adsorber would be overloaded, a catchment volume with overflow is provided above the water inlet.

These systems of the prior art lead to good quality water, but they are large and therefore require a lot of space, not flexible and not easy to maintain.

The aim of the present invention was therefore to provide a compact, flexible and easy-to-maintain cleaning system for wastewater, especially for rainwater and condensation.

Presentation of the invention

This object has been achieved by an adsorber system comprising at least one adsorber arranged in a special collecting container. Such adsorber is referred to as a filter cartridge or cartridge in the sequence.

The inventive adsorbent system is suitable for the treatment of wastewater, especially rainwater and condensation. It is characterized in that it comprises a collecting container and at least one filter cartridge, wherein the bottom surface of the collecting container is larger than the bottom surface of the at least one filter cartridge, the at least one filter cartridge having a housing with at least one access opening for the water to be purified and at least one Having the outlet opening for the purified water and the filter cartridge between the inlet opening and the outlet opening comprises at least one adsorbent layer and wherein measured in the direction perpendicular to the bottom surface, the outer wall of the collecting container is higher than the highest inlet opening of the filter cartridge that the filter cartridge within the collecting container vertically aligned longitudinal extent and in the longitudinal extent at least above the top adsorbent layer, in the region of the access opening, a particle separator or particle filter, in particular a particle ash idendes sieve, comprising.

The collecting container of the adsorber system comprises at least one receptacle for at least one filter cartridge. Such a receptacle can be any holder which is suitable for exchangeable receiving a filter cartridge. This may be a metal scaffold, a concrete scaffold, a plastic scaffold or a scaffold made of two or more of these materials, the separation of the treated from the untreated water and the discharge of the treated water must be guaranteed. This can be achieved, for example, by providing the filter cartridge at the bottom with a drain that can be plugged into a drain pipe in a watertight manner or attached to it, or the receptacle is an opening suitable for sealingly receiving the cartridge, which is located in a plate which extends over arranged a drainage shaft or shaft area.

Basically, the collecting container resp. be the inclusion of at least one filter cartridge made of any material, provided it meets the requirements of stability, tightness and environmental safety requirements.

Alternatively, and currently preferred is an embodiment in which the receptacle is a trough-shaped, directly adjacent to the housing of the filter cartridge and sealed against this depression. This can be made of concrete, for good seal in particular made of plastic-covered concrete or only plastic. It is important that the holder ensures the positioning and sealing of the filter cartridge with respect to the interior of the collection container. Furthermore, the well must provide access of the purified water to a drainage system or leaching. This can be ensured, for example, by the fact that the sealed in the edge region opposite the wall of the recess filter cartridge sits down on a construction of cross-shaped rods, which in turn sit over a discharge ensuring the opening, or that the cartridge against the collecting container sealingly into a recording in Hole-shaped plate is hung. Usually, for reasons of stability, less than half of the longitudinal extent of the cartridge protrudes into the collecting container. In this hinged embodiment, the cartridge can hang freely or it can be supported to relieve the plate in the lower region, which support must be such that both the seal is ensured to the collecting container as well as the outlet of the purified water.

In a preferred embodiment, the holder is a recess as described above, and the filter cartridge is, for example in the lower or in the upper wall region, provided with a support element, in particular a flange or a ring, the lower edge rests on the bottom of the collecting container if the cartridge has been inserted correctly into the holder, so that the cartridge is additionally stabilized. In such an embodiment, the bottom of the collecting container can be designed as a simple, provided with channel-shaped openings plastic or concrete construction, which is sealed as a closure on a hole or inserted into a recess, held for example by below this bottom cross-shaped rods.

For ease of interchangeability and review because of it is preferred if the seal between the housing and trough-shaped depression or opening ensuring means, such as a seal, in particular a sealing ring on the lateral housing wall of the filter cartridge, preferably below a support element is arranged. An assembly with a side seal ring in a lower portion of the filter cartridge also promotes the direct use of such a component as a module for making a modular filter cartridge comprising a plurality of adsorbent layers.

The housing of the filter cartridge may have a serving for supporting on the receptacle supporting element, in particular a flange or ring. A flange is also beneficial when used as a module for making a modular filter cartridge having multiple layers of adsorbent. In one embodiment with a support element, in particular a flange or ring, the seal can also be made via a bearing arranged on this support element or this flange or ring seal. The collecting container can also be designed to promote sealing in the region of this seal also sealing or at least the seal promotional. Also required for sealing is the simultaneous presence of a seal on the side wall of the housing or a cross-sectionally L-shaped sealing ring.

While the cross-section of the filter cartridges can take any shape, such as square, rectangular, oval, hexagonal, etc., a round design is highly preferred, since such can be sealed optimally by means of sealing ring, and assembling the cartridge by screwing corresponding, equipped with threaded parts allows.

In one embodiment, the filter cartridge has at the bottom a water-permeable barrier which retains the adsorbent, in particular a sieve or a membrane, particularly preferably a sieve. This is especially the case with modules arranged one above the other.

Alternatively, the filter cartridge or the lowermost module may have as closure down a water-impermeable barrier and directly above this barrier comprise a means for water removal, for example, a closed with a sieve side drain or a perforated, sieve-like housing portion extending below a filter cartridge opposite the recording resp. the collecting container sealing means, a seal, and, for example, opens into an extension of the trough-shaped depression or a shaft.

For better cleaning, to form an emptying resp. Filling opening and optionally for use as a module, the sieve arranged above the adsorbent layer can be removed, e.g. unscrewable resp. be screwed on, designed.

The sieve may serve for direct particle separation, e.g. when the waste water is fed directly to the filter cartridge. In this case, it is preferable for simultaneous cleaning of the sieve by the impinging water, when the sieve is arranged without protruding edge. For example, in such an embodiment, a drain pipe arranged centrally above the collecting tank opens into a center-symmetrical distribution pipe system, with distribution pipes which, like the spokes of a wheel, extend from the central pipe to one of several circularly arranged filter cartridges, where they overlap one another Filter cartridge arranged drain opening. As a result, even water distribution is achieved. By supplying the water directly to the filter cartridge resp. the sieve arranged at the top will achieve a constant sieve flush when water enters.

Alternatively, the water supply can be made directly into the collecting container, so that only the overflow reaches at least partially completed sedimentation in the filter cartridge and on the sieve. In an embodiment of a filter cartridge according to the invention which is suitable for such an application, the screen may be arranged below the edge of the housing due to the smaller amount of particles, so that a housing edge projecting beyond the adsorbent layer is present.

The collecting container may contain a plurality of filter cartridges. These can all be identically dimensioned or differ in their height and / or their diameter. Different height has the advantage that even with little amount of water, a portion of this water is dissipated. Disadvantages are - depending on the design of the collection container and / or recordings - possibly lower amount of adsorbent and the different service life of the filter cartridges. This disadvantage can be remedied in several ways. On the one hand, the filter cartridges can be hung, so that the cartridges, which are effective even at low levels of water, contain more adsorbents than those that come to bear only with large amounts of water. On the other hand, with an arrangement of the filter cartridges, in which these protrude for the most part in the collecting container, filter cartridges lesser height can be designed with a larger diameter, so that the amount of adsorbent remains substantially the same. Alternatively or additionally, the service life of the filter cartridges can be adjusted by the number of active with small amount of water filter cartridges is increased compared to the only active at large volume of water filter cartridges. By varying the height and / or the diameter and / or the number of filter cartridges and / or by the type of attachment of the filter cartridges resp. the design of the collecting container can be the inventive adsorber optimize in relation to the particular circumstances.

Depending on the requirements, the filter cartridges may contain different adsorbents. For copper, for example, GEH <®> lime (GEH = granulated iron hydroxide) and zinc Ferrosorp <®> (iron hydroxide) For organic compounds, such as roof and facade wastewater or street sewage, activated carbon can be used.

With cartridges containing iron hydroxide, it is highly preferred to design the cartridge and the collection container in such a way that the cartridge, in particular the adsorbent layer, runs dry again and again.

The number and dimensions of the filter cartridges depends essentially on the pollutant load and the amount of rainwater to be purified. It is preferred if the filter cartridges move without major mechanical aids, i. removed from the container and can be replaced by fresh. For example, embodiments with a weight of 20 to 40 kg, in particular 20 to 30 kg, a height of 30 to 80 cm, in particular 30 to 45 cm and, for a circular cross-section, a diameter of 10 to 80 cm, in particular, are suitable for this purpose 20 to 50 cm. Such a filter cartridge can preferably be moved by a single person, possibly by 2 persons.

For heavily contaminated rainwater, it might be useful to choose a stackable modular design, in which case the individual modules may preferably have a weight of 20 to 40 kg, in particular from 20 to 30 kg. In order not to let the overall height of the filter cartridges be too large, it may make sense in a modular design to choose larger diameter and smaller height of the individual module, so that here also an exchange can be done without a heavy lifting device.

For filter cartridges with a large diameter and high weight, especially for stackable modular design, it is advantageous or even necessary to support the arranged below the adsorbent layer and this layer bearing sieve. This can be done in a simple manner by inserting a water-permeable support means, such as a supporting grid, etc. In the case of a thin housing wall, it can also be useful to reinforce it, at least in the area of the barrier, in particular of the screen, for example by means of a reinforcement formed on the housing itself or a reinforcing ring connected to it inseparably connected (for example, welded or glued on).

For better handling, the housings can be provided with holding means, e.g. Handles or grommets for crane ropes. Especially with bulky modules or filter cartridges can then be easier to grasp and move. Holding means can also be useful for heavier modules or filter cartridges, which can only be moved by two or more people.

The cleaning of the collection container, i. the removal of accumulated sediment, for example, can be done periodically with a special suction device.

The supply of rainwater into the collection container or to the filter cartridges can be done directly from the drainage channel or from an interposed retention volume, the outflow or supply to the adsorber in the lower part of the volume, such that even at low flow rates of the inflow ensures the adsorber and the retention volume can still fulfill its function as a buffer for large amounts of water. For extreme rainfall an overflow at the collecting tank can be provided. This may be an empty cartridge, the water inlet is above the highest water inlet of a filter cartridge, in particular about 0.5 to 1.5 m above the highest water access to a filter cartridge, or to a pipe, in particular a ring-provided pipe, in such, that both the empty cartridge as well as the tube sealingly attached to the bottom of the collection container, eg be screwed. Alternatively or additionally, an overflow can also be provided laterally. This can, for example, also lead to a further collecting container or a further adsorber system.

Ways to carry out the invention

Figs. 1A and 1B show a filter cartridge 1 having a housing 4, a particle separator or particle filter 5, e.g. a sieve or a water-permeable membrane, here identical to the access opening 6, an outlet 9, separated from the adsorbent layer by a barrier 7, here a water-permeable barrier 7, e.g. a screen or membrane, such as a filter cloth, and the adsorbent layer 10, shown as empty space in Figure 1B (corresponds to the space bounded laterally by the housing 4, through the top of the particle separator or particulate filter 5 and down through the barrier 7) , The particulate trap or particulate filter 5 may be fixedly connected to the housing or, as shown in FIG. 1B, removable, e.g. on or unscrewed, be designed. For positioning in a receptacle 22, the housing 4 in the lower region is preferably designed such that it has a foot 11 engaging in a receptacle 22 and a supporting element 12 lying on the receptacle 22, e.g. a flange or ring. For better sealing between the filter cartridge 1 and the foot 11 and the wall of the receptacle 22, the filter cartridge 1 is resp. the foot 11 with a seal 8, in particular a sealing ring provided.

In Figs. 2A and 2B, the modular structure of filter cartridges is shown. Such modules 15 have substantially the same structure as the above-described non-modular filter cartridges 1, except that the lowermost and all central modules 15 (in Figs. 2A and 2B, only 1 central module is shown) without the Particle filter or particle filter 5 can be designed. For optimum variability, it is preferred if the modules 15 are all identical and configured such that they can be connected to one another, wherein the uppermost module is connected to an attachment comprising the particle separator or particle filter 5 instead of another module. The lowermost module, instead of being connected to another module, is placed in a suitable receptacle, as described above.

A suitable and currently preferred way of connecting two modules is that at least one of these modules instead of the above the adsorbent 10 arranged particle separator or particulate filter 5 has an adapter 16, in which the next module 15 is inserted and on which it preferably with the support element 12 rests. The adapter 16 may be connected to the upper part of the housing wall of the lower module 15 fixed or detachable, for example by means of a screw connection.

FIGS. 3 and 4 describe two different embodiments of the adsorber systems according to the invention. 3 shows an adsorber system with filter cartridges 1 arranged concentrically in a circular collecting container 2. The waste water is passed directly to each filter cartridge by collecting the waste water in a tube 31, the lower end of which is arranged centrally above the collecting container 2 and in the region of the collecting container 2 opens into a center-symmetrical distribution system 32. The center symmetry is advantageous to ensure regular loading of all filter cartridges.

In the alternative embodiment, which is shown in Fig. 4, the waste water is collected in one or more downcomers 3 and passed into the collecting container 2, where a part of the coarse material already sediments. If the water level in the collecting container has reached the height of the inlet opening 6 of at least one filter cartridge 1, the water flows through the inlet opening 6 of the filter cartridge 1, through the at least one adsorbent layer 10 and is then discharged through the outlet opening 9 as desired. In this embodiment, the arrangement of the cartridges within the collecting container 2 may be arbitrary.

5 shows further alternative embodiments. 5A shows a plan view of a round collecting container 2 with concentric arrangement of filter cartridges 1 and central supply line 3 of the waste water into the collecting container 2.

Fig. 5B shows a section through the embodiment according to FIG. 5A, wherein in this embodiment all the filter cartridges 1 have the same height and the wall 21 of the collecting container 2 is higher than the filter cartridges 1. In this embodiment, the filter cartridges 1 are in arranged as wells receptacles 22, from which the purified water via leads 23 is removed.

Fig. 5C shows an embodiment analogous to the embodiment shown in Fig. 5B, with the difference that even at low water volumes or low water level in the collecting container water is discharged. This is done in an arrangement according to FIG. 5Addurch that filter cartridges 1 different heights are used. Shown are filter cartridges different height but the same diameter. In order to obtain approximately the same service life for all filter cartridges 1 in such an embodiment, either more short filter cartridges 1 can be used and / or filter cartridges 1 whose diameter increases with decreasing height.

It is also within the scope of this invention to use filter cartridges the same height and with different diameters, as well as filter cartridges with different adsorbents. If, for example, it is known from analyzes that an element is washed out of an alloy with small amounts of water and the ratio of heavy metals changes when the amount of water is large, for example, the cartridges, which are already effective at low amounts of water, increasingly rely on adsorption the one pollutant are aligned, those that are used only in high amounts of water, on the then resulting load.

By means of the system according to the invention it is also possible to optimize the cleaning for average rainfall, e.g. with many "short" cartridges for rain with moderate volume of water and a few cartridges with higher water intake for extreme rains. These cartridges for extreme rainfall can also be optimized by designing them with a wide diameter (access of large volumes of water in a short time) and low height (adjustment of service life) and adjusting the inlet by positioning it on a base which determines the inlet height (see FIG. 6).

Fig. 7 shows an alternative embodiment of a filter cartridge 1, which engages not only in a lower region in a receptacle 22, but is hooked into a receptacle 22, that is, serving more than 50% of its length in a drain Shaft 23 is located, which extends below a bottom 24 of the collecting container 2 forming plate. In this embodiment, a support member 12 is mounted in an upper portion of the housing 4 of the filter cartridge 1, wherein the support 12 is provided in one embodiment (shown in Fig. 7 right) in its lower wall preferably with a sealing ring 8, which as sole or additional sealing of the filter cartridge 1 relative to the bottom 24 of the collecting container 2 is used. Alternatively (shown in Fig. 7links), the seal may have L-shaped cross-section. Fig. 7 further shows that the adsorbent layer 10 covers the entire space between two water-permeable barriers, e.g. Seven, or that they unilaterally or bilaterally, for. may have a gravel or gravel layer, or above only an empty or rainwater-containing space 13. This embodiment of the adsorbent-containing area is not limited to this embodiment, but a general design option of the filter cartridges. Depending on the housing design, it may be useful or even necessary to reinforce the housing wall in the region of the lower, supporting screen, for example with a ring 14th

An analogous embodiment, in which less than 50% of the length of the filter cartridge are located below the collecting container, can also be provided, wherein the stability and thus the secure seal can cause problems.

For heavily varying amounts of rain, it may be useful to provide an additional retention volume in front of the container 2, the outflow is located deep, so that even small amounts of water are forwarded to the adsorber, and yet a large additional collection volume is available for exceptional situations. It is also within the scope of the invention to design the collecting container with an overflow, which discharges the water directly into the sewer system or infiltration, or into a downstream adsorber system, so that the first adsorber system simultaneously serves as a filter system and as a retention volume.

Also in the context of this invention is a plant control, which makes it possible to determine the amount of water that has flowed through a special filter cartridge and - if assumed full load - at best to close the access to this cartridge or replace this cartridge targeted.
