Description

The The invention relates to a process for the treatment of water, where treatment water in a biotope zone interacts with Organize a first treatment step and in a soil filter zone by intermittent flow through a porous substrate soil at least a bottom filter basin undergoes a second treatment step.

The Invention further relates to a water treatment device, comprising a biotope zone in which organisms interact with Treatment water are arranged, as well as a soil filter zone, in the treatment water through a porous substrate soil at least one bottom filter basin is conductive.

Such methods and devices are known from the DE 20 2005 016 380 U1 , This document discloses a water treatment system for the treatment of the water of fish farming ponds. The system includes a use area where fish are used and a treatment area into which raw water to be treated is introduced, treated and transferred to a fining pond, from where it is returned as pure water to the utilization area.

in the As used herein, the term "treatment water" refers to the water independent in the treatment zone used by its origin or its degree of purification. Especially the term includes reprocessed, straight into the treatment zone introduced raw or filling water, as well as already processed and discharged from the processing zone Pure water and all Stages of partially treated water.

at the known device comprises the pre-fining part of the treatment area a biotope zone and a soil filter zone, the vertically one above the other layered are arranged. The biotope zone is called root zone formed, settled in the root-forming, emerse aquatic plants are. This root zone is overflowed by the treatment water, wherein the plants provide nitrogenous nutrients to the treatment water revoke. Below the root zone is one of sand and gravel formed Sickerbett arranged to extend under the drainage pipes. The drainage pipes are connected to a pump, with which the Suction water sucked under the Sickerbett and into the fining pond can be fed. The operation of the pump is intermittent intended. This means that in each case after a given interaction time of treatment water with biotope zone plants in which the treatment water undergoes a first treatment step, the Water level in the processing zone is suddenly and drastically lowered, so that the treatment water the Sickerbett as a soil filter goes through essentially vertically, wherein it undergoes a second processing step.

The known system used for the treatment of water in fish ponds may be suitable for the water treatment for bathing water and swimming and bathing pond systems, in particular with salt water, not suitable. Due to the vertical stratification of Biotopzone and Soil filter zone prevails in the soil filter zone is an essentially anaerobic Milieu. This is in the known system for targeted denitrification used the treatment water. However, this does not happen here for swimming and bathing ponds particularly important germ count reduction. This is limited to the aerobic areas of the root zone, what to comply with the statutory hygiene standards for bathing water and Swimming and bathing pond facilities is not sufficient.

One Another disadvantage arises in the use of salt water. Under salt water here is water with a salt concentration of at least 10 per thousand understood. As a rule, swimming pools and bathing ponds with salt water salt concentrations similar to those Have salt concentrations of the seas, i. typically between 10 and 43 per thousand. In such an environment, even salt-tolerant plants can do not thrive.

From the DE 22 01 116 is a water treatment system for swimming and bathing ponds known in which raw water is withdrawn from different heights of the use area and pumped into a designed as a treatment pond treatment area. The bottom of the treatment pond is formed from a porous substrate, which can act as a soil filter. The water of the treatment pond is drained below the floor filter with drainage pipes and directed back into the utilization area, whereby a constant flow is realized, which uses the natural gradient from the higher treatment pond to the lower lying utilization area.

A disadvantage of this system is the lack of reduction of the nutrient content in the treatment of water. Nutrients are usually retained only to a limited extent by a pure soil filter. There is thus the danger of eutrophication of the swimming and bathing pond. Another disadvantage of the known system is the constant overstocks of the soil filter with Aufbereitungswas to mention these. This will exhaust itself over time in its germ reduction capacity. To regenerate complex measures must be taken, such as the targeted introduction of oxygen.

From the DE 101 28 930 B4 a water treatment system for a swimming and bathing pond is known, in which a treatment area designed as a treatment pond, the bottom substrate is used as a soil filter, is lower than an adjacent area of use. The extracted under the soil filter with the help of drainage pipes and a pump water is fed via a wave generator in the higher area of use. The resulting waves make the surface water of the utilization area slosh over an overflow device into the treatment pond, so that a cycle is ensured. Again, the main disadvantages are the lack of nutrient reduction and the expected exhaustion of the soil filter.

From the DE 201 18 272 U1 For example, the purification of water by rooting plants planted on swimming facilities is known. These mobile biotope zones floating on the water surface are able to locally reduce the nutrient content of the pond water.

by virtue of the floating position of the swimming facilities, this nutrient reduction takes place however exclusively near the surface. This is for swimming and swimming ponds insufficient. Next, the swimming facilities are located directly on the surface of the used for cleaning pond, which clearly shows its useful for bathing area reduced. continue to be allowed such overgrown swimming facilities attract waterfowl, with the nutrient input over their Feces overcompensate the cleaning effect of the floating biotope zones likely. After all This known system does not include any necessary measures Germ reduction.

From the DE 197 37 299 A1 For example, a method and apparatus for the biological restoration of eutrophicated waters is known. Similar to the subject matter of the previously discussed document, this system is also based on the cleaning effect of overgrown biotope zones arranged parallel to the water surface. However, these are connected by guides to the bottom of the water, so that they can be moved to different depths of water to exercise their cleansing effect in different water depths can. As growth for the mobile biotope zones, among others, "algae" are proposed in the cited document. As with the mobile biotope zones discussed above, the lack of germ reduction must also be considered disadvantageous in this embodiment, especially in the case of a potential use for the purification of swimming and bathing ponds. Furthermore, the guided tours anchored to the ground and extending to the surface for the depth adjustment of the mobile biotope zones in swimming and bathing ponds pose a considerable risk of injury.

From the DE 93 04 306 U1 a device and a method for the purification of garden pond water with a horizontally flow through, combined biotope and soil filter zone, wherein an inlet to the pond is designed as a flow channel whose cross-section is completely fulfilled by successively staggered in the flow direction, water-permeable planters. In the planters are arranged in rows alternately root-forming plants and granular filter substrates. As it flows into the pond, the water flows alternately through root zone zones and soil filter zones. The feed is fed with pond water pumped out of the pond.

adversely Here, the high maintenance of the combined treatment zone, if the principle applies to larger ponds is to be used as disclosed in the document Garden pond. With increasing plant growth and deposition of Filtered material is namely the flow through significantly reduce the processing zone. In addition, the plants with their roots in the immediately adjacent soil filter layers immigrate. Here to a constant rate of treatment of the pond water to achieve consistent quality of treatment, the complicated System of the flow zone constantly be adjusted. this leads to especially for large ones Facilities at considerable work and expense. In addition, the disclosed device not suitable for use with salt water.

It the object of the present invention is a generic method and a generic water treatment device in such a way that the disadvantages of the prior art at least partially overcome become. In particular, it is the object of the present invention Water treatment processes and devices available provide suitable, water, especially of swimming and Bathing ponds with salt water, in a cost-effective and natural way to process so that the high legal hygiene standards permanently Fulfills can be.

It is another object of the present invention, a swimming and bathing pond, esp salt water, which complies with these hygiene standards in a cost-effective and natural way.

These Tasks are solved with the characteristics of the independent Claims.

advantageous versions of the invention are in the dependent claims specified.

The Invention is based on a generic method with the features of the preamble of claim 1, characterized in that as organisms macroalgae and / or shells attached to support elements, which a flow area the treatment water perpendicular to the flow direction substantially Completely enforce and that the soil filter zone a plurality of soil filter basins comprises, the phase-shifted intermittently with the treatment water with a total inflow from the habitat zone in the soil filter zone is kept substantially constant. alternative or additionally can used as organisms of the biotope zone red algae and / or sponges become.

The Invention continues to build on a generic water treatment device characterized by the features of the preamble of claim 14 that provided as organisms macroalgae, red algae and / or shells that are attached to support elements are fixed, which has a flow area the treatment water perpendicular to the flow direction substantially fully enforce and that the soil filter zone comprises a plurality of soil filter basins comprises, the phase-shifted intermittently with the treatment water are loadable, so that a total inflow from the biotope zone in the soil filter zone is substantially constant. Alternatively or In addition, as Organisms of the biotope zone red algae and / or sponges are used.

The Invention finally relates a swimming and bathing pond with the features of claim 28.

to Avoidance of repetitions should have the characteristics, effects and Advantages of the present invention with regard to the inventive method and the devices according to the invention below be discussed together.

First is According to the invention, that used as organisms of the biotope zone macroalgae and / or shells become. These organisms are used to remove nutrients and suspended matter from the treatment water. The combination of both types of organisms is particularly advantageous because the shells have a particularly good filtration effect have while the macroalgae by strong biomass increase the treatment water in big Scope nutrients revoke. conveniently, while the shells are spatially used in front of the macroalgae, so that they also excreted those nutrient can escape the treatment water.

The Biotope zone is designed as a flow area. This can be done, for example, by designing the biotope zone as open channel. Alternatively or additionally, the embodiment as flow channel or stream basin, in which the water follows a substantially circular flow, possible. According to the invention For cleaning used organisms attached to support elements, which are perpendicular to the flow direction are set up. This is essentially the entire flow cross section interspersed by the occupied with the organisms carrier elements. you Note that the term "vertical" does not refer to the mathematically exact term reduced to understand is. Much more should all Mounting methods of the support elements includes, one to the flow direction have vertical component, i. all those that are not essentially parallel to the flow are arranged. This will ensure that the entire Volume of treatment water with the active elements of the biotope zone, i.e. the macroalgae, red algae or shells comes into contact. The Arrangement of several carrier elements in the flow direction successively improves the efficiency of nutrient reduction in the biotope zone. By preferably separately replaceable design of the support elements can the number of elements easily the desired degree of purification or the stocking density to be adapted to the individual support elements. Advantageous embodiments of the support elements are below described.

It is further provided according to the invention that the soil filter zone comprises a plurality of soil filter basins. This is based first of the knowledge that the exhaustion of a soil filter can be counteracted by the soil substrate through which the treatment water has to flow to reduce germs, is allowed to dry temporarily, so that a ventilation can be done with oxygen from the ambient air. However, such a dry traps necessarily requires an interruption of the influx. On the other hand, the sterilization can be particularly efficient if the treatment water before drainage through the soil substrate, a rest and contact phase is granted, which also requires an interruption of the inflow into the soil filter pool. If, as provided according to the invention, the soil filter zone connected to a biotope zone, such an interruption of the influx would be in the Bo denfilterzone mean an interruption of the flow through the biotope zone. This is undesirable. According to the invention, it is therefore provided that the plurality of bottom filter basins are charged out of phase with each other, so that the flow of the connected biotope zone can be maintained when interrupting the inflow into a first floor filter pool by the influx is passed into a second soil filter pool at these times. The concrete number of soil filter basins depends on their respective intake capacity, the flow rate of the connected biotope zone as well as the complexity of the feed cycle of the individual soil filter basins. By suitable adaptation of the parameters to each other, it can be ensured that the inflow from the biotope zone (if this is upstream of the soil filter zone) or into the biotope zone (if the soil filter zone downstream) and thus the flow rate of the biotope itself can be kept constant.

Of the Advantage of the present invention is to be seen in that with essentially natural or close to nature means a multi-stage treatment of water done which provides a consistent and in the long run not exhaustive treatment quality, which meets the high standards for swimming and bathing pond water quality equivalent. In addition, the plant is due to the choice of organisms in the biotope zone for suitable for the treatment of salt water.

It be noted at this point that by combining the two principal Invention aspects, namely the design of the biotope zone on the one hand and the soil filter zone on the other on the other hand achieves a special efficiency of the cleaning effect becomes. Nevertheless, each of the two offers as an independent invention considered, advantages over the devices and methods of the prior art. The Both aspects and their below to be explained, particularly advantageous Embodiments should therefore expressly not only in combination but also disclosed separately.

Under an intermittent feed of a bottom filter basin is in the context of the present invention, an inlet and outlet of Treatment water in or out of the pool understood, wherein by controlling the inflow periods in which the soil substrate the soil filter basin is flowed through by the treatment water, alternates with periods in which such a flow in the Substantially prevented, e.g. because the soil substrate dropped dry or because the soil substrate overstocks statically during this period is. The intermittent charge can vary with different Level heights in the floor filter basin accompanied.

Especially It is advantageous if the control of the soil filter zone in such a way is designed that the intermittent feed of each floor filter basin in cycles, each one filling the basin up to one predetermined first level, a period without change the level and deflation to a predetermined second level, which is lower than the first level comprises. Preferably is during of filling of the pelvis prevented its drainage during the period without change the level of both the outflow was prevented as the influx and during the draining of the basin prevented the influx. In this way, you can choose between the refill phase and the discharge phase a rest and contact phase are realized in which the treatment water has sufficient opportunity with to interact with the soil substrate, which improves germ reduction. The following Draining the treatment water through the soil substrate has a additional filtering and disinfecting effect.

Preferably it is envisaged that the substrate bottom of each soil filter basin periodically dry. This is conveniently done following the discharge phase and before a subsequent replenishment phase. While the dry phase, the substrate bottom is due to contact with the Ambient air and in particular their oxygen regenerated. This may possibly by additional mechanical processing, such as raking, raking etc. of the substrate bottom while the dry phase supported although such an additional measure is generally not required will be. By suitable water level control is for one Lower area of the pelvis allows a longer contact phase while getting an upper area is in the dry phase.

Conveniently, a sprinkling device for introducing the treatment water is arranged above at least one of the bottom filter basins. The fact that the treatment water is introduced via the Verrieselungseinrichtung, a particularly effective utilization of the entire soil filter surface is achieved. The sprinkling device preferably extends substantially over the entire bottom surface of the bottom filter basin and is particularly preferably provided above each bottom filter basin. The introduction of treatment water into the watering system can be carried out under pump pressure with the aid of a pump, in order to realize a substantially identical introduction of water at each point of the bottom surface. However, the same objective can be achieved even more favorably by introducing the treatment water without a pump following a gradient into the sprinkler system becomes. The uniform wetting of the substrate bottom can be realized in that the size and / or density of outlet pores in lines of the watering system are staggered so that the pressure loss in the lines is compensated.

at an advantageous embodiment of the invention is provided that below the substantially entire floor surface at least one of the bottom filter basins Drainage pipes for draining the treatment water are arranged so that the treatment water over this Drainage lines can be drained. Preferably, such Drainage lines are arranged under such soil filter basins, over which the previously discussed Verrieselungsanlage is mounted. The large-scale draining leads to a substantially vertical throughput of treatment water the soil substrate.

When Bottom substrate of at least one of the bottom filter basins is preferably an adapted to physico-chemical properties of the desired water quality provided mineral substrate. This can be especially in saltwater installations, similar to sea sand and / or gravel from deposits Act on salt concentrations. The substrate fulfills by its grain distribution and size on the function of an egg and larval filter to increase animal growth in the technical installations, the pipelines and the utilization area (e.g., bathing area). In a development of the invention a special filter can be used upstream or downstream of animal growth be or be.

In Regarding the design of the habitat zone are at a preferred embodiment the invention additionally used to macroalgae and / or shells red algae and / or sponges. red algae and especially tropical sponges especially for use in systems with higher water temperature and higher Salinity of the water suitable. The red algae take over or support it essentially the effect of the macroalgae, i. of nutrient deprivation by biomass formation. Take over the sponges or support essentially the filtration effect of the mussels. They show but a stronger one Biomass formation as that, which also supports the impact of macroeconomic or red algae means. Possible Areas of use are e.g. Outdoor plant in warm regions or Indoor facilities. Also, is a temporary use in outdoor facilities in colder Regions during the summer months conceivable, with the red algae or sponges at Falling temperatures die off by themselves. At a special embodiment the invention can Macroalgae and / or the shells completely by red algae, sponges or a combination of these will be replaced.

When Macroalgae is preferred bladderwrack (Fucus versicolor), sea lettuce (Ulva), Darmtang (Enteromorpha sp.), Knotentang (Ascophyllum nodustrum) and / or cartilaginous (Chondrus crispus). General can ever according to requirement, location and salinity also other or other species be used. Red algae are preferably kept at very high salt levels used.

When Mussels are preferably provided with mussels and / or oysters.

to Attachment of the organisms to the support elements is preferred provided that at least part of the organisms in pockets of across the flow strained networks are arranged. The net bags should be there favorably have a mesh size, the a good water flow but at the same time adapted to the size of the organisms are that they are held securely in the mesh pockets. The Providing a plurality of individual pockets on a tensioned one Network has opposite a double-walled version of the network, i. essentially just a mesh bag, the advantage that the trimming with organisms over the entire area permanently can be maintained and there is no danger that the organisms following gravity down. This mounting form is also with regard to care, maintenance and further utilization, e.g. by marketing the proliferating macroalgae, such as the aspect of easy removability advantageous.

For the attachment of shells, on the other hand, it may be advantageous to apply them to the cross flow direction cocked or hanging To set hawsers. For the mussel breed it is known to grow shells on long hawsers allow. Such overgrown hawsers can e.g. in vertical and / or horizontal orientation transverse to the flow direction in the flow region the biotope zone.

in order to improve the cleaning effect, in particular of the mussel stocking, it is advantageously provided that in the biotope zone, gas lines for bubbling through the treatment water are arranged with a particularly growth-promoting gas and the water in the flow area is bubbled through by the gas. As a gas, for example, oxygen for the shells or carbon dioxide for the macroalgae in question. The main purpose of the bubbling is, however, that this way a targeted flow around the organisms can be achieved with the treatment water, which also sedimented substances can be whirled up and brought to the organisms for cleaning NEN.

conveniently, the habitat zone is divided into a plurality of single basins, the above Sills are interconnected. Under a sill is in the context of the present invention, not reaching to the water surface increase in the Pelvic floor understood, the increase preferably from a grained Substrate, for example, held in water-permeable bag fabric is, exists. For one, such sills have a filtering Effect for suspended solids. On the other hand arise in the flow shadow the sills swelled Areas where solids can sediment. In addition, can as a sill-barrier material physically-chemically active material, such as phosphorus binding material can be used. By the to be derived from simple flow laws flow acceleration above the sills can be an additional oxygen input be effected in the treatment water.

as mentioned, the invention is particularly suitable for the treatment of water for swimming and Bathing ponds with salt water. It is therefore preferred that the treatment water has a salt content of at least 10 parts per thousand having.

1 shows a schematic plan view of a swimming and bathing pond according to the invention, in particular with salt water. The swimming and bathing pond only partially covers its shore 101 shown usage area 10 , The usage area 10 is in different ways with a conduit system 20 connected. In 1 shown are two water extraction devices 102 inside the usage area 10 , The water extraction devices 102 , which are also called "monk", are preferably designed so that either raw water from different water depths on the with each monk 102 connected line 21 into the pipe system 20 can be fed. Depending on the embodiment, the feed can take place via a pump device or, preferably, over a free gradient. Another deduction for raw water, especially for surface water offers only schematically illustrated overflow 103 on the edge of the river 101 of the usage area 10 , The overflow 103 may be rigid or in a manner adapted to different water levels. That over the overflow 103 from the usage area 10 withdrawn surface water passes through a collecting shaft 22 into the pipe system 20 , In the collection shaft 22 They also unite over the monks 102 withdrawn amounts of water. In 1 is just a common node 22 the conduit system shown schematically, which can be designed differently depending on the embodiment and in particular can represent a collecting shaft and pump unit. Alternatively, separate and separately controlled feeds can be realized. Next connected to the piping system is in the illustrated embodiment, a loss water compensation line 23 , For example, by evaporation from the system escaped water can through the line 23 be replaced. The administration 23 is preferably connected to an adjacent filling water source, in particular an adjacent sea, a brine source, optionally combined with a rainwater collecting container. Conveniently, the conduit system 20 designed with controllable valve means such that one and the same central pump depending on the circuit state either water from the use area 10 or over the equalization line 23 from the neighboring waters into the pipeline system 20 can feed, with the circuit preferably the filling water availability is observed. The uniform flow through the system should be taken into account.

From the pipe system 20 The collected water is fed through a feed line 24 as treatment water in a biotope zone 30 one of the pond 10 fed to adjacent water treatment system.

In the illustrated embodiment, the habitat zone comprises 30 three parallel arranged and interconnected treatment tanks 31a c. The treatment tanks 31a -c are from the via the feedline 24 turned supplied water flows through one after the other.

Transverse to the direction of flow are occupied with macroalgae, red algae, shells and / or sponges, preferably replaceable support elements 32 . 33 arranged. In the presentation of 1 For the sake of clarity, only a few of the support elements 32 . 33 provided with a reference numeral. The carrier elements 32 . 33 and the organisms attached to them, which are the active elements of the biotope zone 30 represent, are continuously flowed through by the treatment water. In the illustrated embodiment are different basins 31a -c with different support elements 32 . 33 equipped. However, it is also possible to make all support elements the same or to use several types of support elements in a basin. The individual basins are in the illustrated embodiment by Sohlschwellen 34 separated, whereby already in the biotope zone a filtering and sedimentation effect for suspended matter is realized.

After passing through the biotope zone 30 is the treatment water via a connection system 40 a soil filter zone 50 fed. The connection system 40 For example, it can be designed as an open channel system, which can be switched, for example, with flaps or bulkheads, so that individual bottom filter basins 51a -d the soil filter zone 50 can be charged separately or together with treatment water. Alternatively, or in addition to the open channels, a pipe or hose system can be realized, which is above the floor filter pool 51a -d flows into a not shown Verrieselungsanlage. The water transport from the biotope zone 30 to the soil filter zone 50 can take place depending on the embodiment, taking advantage of natural gradient and / or with pump assistance.

Under the floor filter basin 51a D is preferably arranged a drainage device, not shown. This serves to feed the in the soil filter zone 50 purified treatment water in a return piping system 60 , In 1 is only schematic for each soil filter basin 51a -d a deduction 52a -d and a discharge line 53a -d (the latter dashed) shown. The return line system 60 is with the usage area 10 connected and serves the supply of purified treatment water as pure water in the pond 10 , For this purpose, the water is preferably at one or more locations above the waterline in the use area 10 flowed. For this purpose, nozzles can 61 be provided, which support an enrichment of the fresh water fed with the atmospheric oxygen.

2 shows a first embodiment of a carrier element 32 for holding organisms in a basin 31 the biotope zone 30 , The carrier element 32 includes a network in the illustrated embodiment 321 , Which transverse to the flow direction of the treatment water so in the biotope basin 31 is clamped that it passes through the flow cross-section substantially completely. For this purpose, for example, clamping posts 322 in the basin 31 be anchored. At the net 321 is a variety of mesh pockets 323 arranged in which 2 not shown organisms such as macroalgae, red algae, shells and / or sponges are set. The net bags 323 are preferably relatively uniform over the entire surface of the net 321 distributed.

3 shows a second embodiment of carrier elements 33 in a biotope basin 31 , In this embodiment are Spanned ropes 331 transverse to the flow direction of the treatment water so in the basin 31 curious that they essentially span its entire flow cross-section. Between the chicks 331 are holding dogs 332 looking forward to those shells 333 especially mussels and / or oysters set, preferably are solid. The holding lugs are preferably distributed substantially uniformly over the flow cross-section.

4 shows an embodiment of a sill for the separation of individual biotope basins. As Sohlschwelle preferably serves a bed of substrate 34 , which does not reach the water surface, so that the treatment water can flow from one biotope basin into the next. In the flow shadow of the substrate bed 34 there is a sedimentation of suspended matter. In addition, the substrate itself, depending on the choice of material, have a filtering effect. Preferably, on the crest of the bed of substrate 34 a broken row of stepping stones 35 arranged, which protrude above the waterline. In this way, the overflow of the bed 34 only insignificantly obstructed, on the other hand, a cost-effective and comfortable footpath for operating and maintenance personnel of the system is created. Alternatively to the in 4 shown substrate bed 34 can also be used in water-permeable containers, such as sacks, stored substrate.

5 schematically shows a particularly favorable embodiment of a soil filter zone 50 with four floor filter basins 51a -d in four different phases I-IV of their preferred drive.

Every pool 51a -d has a bottom substrate 511a -d on, which may be the same or different in different tanks. In particular, the use of sand, especially unfiltered Jadesand has proven to be cheap. The pelvis 51a -d are from the upstream biotope zone 30 over the common connection line 40 fed. This flows over each basin in a sprinkler system 41a d. The inflow into each basin can be achieved by one valve flap each 42a -d admitted or inhibited and preferably also be controlled in its flow rate. Below each floor filter basin 51a -d, a drainage system is applied, preferably under the entire surface of the bottom substrate 511a -dake the treatment water evenly and into the return line 60 can feed. The feed into the line 60 can each be through a valve flap 54a -d allowed or inhibited and preferably also controlled in the flow rate.

In 5 a four-phase control scheme is shown. The individual partial images of 5 each show a state approximately in the middle of the time of each phase I-IV. As initial state of 5 a condition can be assumed in which the pelvis 51a empty, the basin 51b full, the pelvis 51c also full and the pelvis 51d again is empty.

Phase I is characterized by the inflow flap 42a of the pelvis 51a as well as the wastegate 54c of the pelvis 51c are open, while all the other butterfly valves are closed. As a result, treatment water over the sprinkler system 54a large area in the soil filter basin 51a drizzled, with an outflow is prevented, so that the water level rises during phase I. At the same time, treatment water is released via the drainage device 53c under the basin 51c collected over a large area, whereby the water level in this basin decreases and the treatment water sinks the soil substrate 511c flows through. The control of the valve flaps is preferably designed so that the influx into the connecting line 40 in about the outflow into the pipe 60 equivalent. During phase I, the condition of the pelvis remains 51b and 51d unchanged. This results in the filled pool 51b a rest and contact phase in which the treatment water with the substrate 511b can interact. In the empty basin 51d the substrate interacts 511b however, with the oxygen in the air and is thereby regenerated.

In Phase II, which starts when the pelvis 51 ran and the pelvis 53c fell dry, the flaps are 42a and 54c closed. Instead, the exhaust flap 54b of the pelvis 51b and the inflow flap 42d of the pelvis 51d open. This means that in phase II the pelvis 51a the rest and contact phase goes through the pelvis 51b under filtering of the treatment water stored in it in the line 60 is emptied that basin 51c undergoes a regeneration phase and the pelvis 51d is filled under large-scale trickling. Note that the total inflow into the interconnector 40 and the total effluent in feed line 60 stay constant. This also means that the flow through a upstream or downstream biotope zone can be kept constant.

In phase III, the pelvis 51a by opening its drain flap 54a emptied, the pelvis 51b goes through a regeneration phase, the pelvis 51c is by opening his influx damper 42c filled and the pelvis 51d goes through a rest and contact phase.

In phase IV finally passes through the basin 51a a regeneration phase, the pelvis 51b is by opening his influx damper 42b filled, the pelvis 51c goes through a rest and contact phase and the pelvis 51d is by opening its drain flap 54d emptied.

in the Following phase IV, the control scheme preferably begins from before.

When favorable phase length has proven to last about 15 minutes for each phase I-IV, so that each cycle has a duration of about 1 hour.
