Definitions

  • the invention relates to a storage/seepage system for a fluid, preferably for rainwater.
  • the invention relates to a method for temporarily storing a fluid in a storage/seepage system.
  • trenches containing distribution pipes and filled either with gravel or with seepage devices are often used for the temporary storage and infiltration of rainwater.
  • Modern storage/seepage systems often contain modular hollow bodies that together form the static support of the tank and, depending on the application, are covered with an open-pored membrane, for example a non-woven fabric (seepage system) or foil (storage system). Due to their construction, these hollow bodies contain a large number of different struts that serve to absorb or dissipate force. They are often designed as boxes that can be laid or attached to one another and one on top of the other, which together form the supply channels and the necessary cavity for the rainwater. They are usually so stable that the area above them can be used as a roadway or parking lot.
  • Such storage/infiltration systems are sensitive to contamination from solid deposits and the entry of oil or other light liquids.
  • the seepage systems are equipped with a casing made of water-permeable material (open-pored membrane), through which the temporarily stored rainwater can seep into the ground in a defined quantity and speed. If a rain event brings a corresponding pollution load into the system, solids are deposited as sediment. As a result, after a short time, the water-permeable casing will become so heavily clogged that water drainage can no longer take place, or only to a limited extent.
  • the storage tank In a storage system that is equipped with a watertight, tight casing, the storage tank gradually silts up over its entire base area until the entire storage volume is blocked. Since storage is generally used for retention and time-delayed derivation, blocking disrupts the flow and storage function and significantly reduces the performance of such a system.
  • the U.S. 5,810,510 A describes an underground drainage system comprising pipelines and storage tanks fabricated from perforated wall modules to form a configuration wrapped with a water permeable geotextile.
  • the system is preferably buried in clean sand, with rain and runoff water directed to flow through the water permeable geotextile, through the perforated wall modules and into the pipeline where the water thus filtered is allowed to flow along the pipeline to penetrate through the walls of the Pipeline to flow back into the first available layer where the surrounding soil is not saturated.
  • a system for collecting rainwater comprising a body, a filter layer, a rainwater outlet opening and a device for removing rainwater.
  • the body includes a stormwater inlet, a stormwater outlet, a sand trap, a particulate separator and a filter tank.
  • the filter layer consists of two sponge filters and an activated carbon filter.
  • the rainwater drainage hole is formed on the bottom surface of the sandbox and includes an opening and closing plate, a float and a post. The opening and closing plate covers the inlet of the rainwater drainage opening.
  • the post opens the opening and closing plate by the load of the float and allows the opening and closing plate to close the rainwater drainage hole when the float floats on the water.
  • the GB 2 468 531A describes a tank consisting of an inlet, at least one outlet, a water-permeable cage and a filter bag.
  • the filter bag is preferably attached to the water-permeable cage by means of attachment means.
  • the water permeable cage and a detachable baffle may be located inside the tank.
  • water is supplied to the inlet and flows into the filter bag, whereupon sediment is retained. The water then flows over the baffle, which retains more sediment, and then drains out the outlet.
  • the container is used to filter pump outflow in a drainage system.
  • U.S. 2003 034 286 A a flow-through drain filter for removing dirt, sediment, liquid hydrocarbons and metal ions, consisting of at least four concentric screens with a de-ionizing filter material positioned between an exit screen and a second central inner screen, and a hydrocarbon-repellent and liquid hydrocarbon-absorbing material disposed between the first and second middle screens, and a sediment collection space between the first middle screen and a dirt exclusion inlet screen.
  • a key aspect of the invention is the purification stage which is integrated into the storage/infiltration stage.
  • the purification stage cleans foreign matter from the fluid before it is received by the storage/soak stage. This protects the storage/infiltration system from collapsing or blocking and the storage/infiltration system remains efficient over the long term.
  • the fact that the cleaning stage is integrated into the storage/infiltration stage, or that the storage/infiltration stage is integrated into the cleaning stage, has the storage/infiltration system no increased space requirement.
  • the operating and investment costs are lower.
  • the integration of the cleaning stage or storage/infiltration stage also results in a significant reduction in the installation effort.
  • the purification stage is preferably integrated into the storage/infiltration stage.
  • the purification stage is designed to fall dry and to release the fluid essentially completely to the storage/soak-off stage. Drying out of the cleaning stage means that the cleaning stage does not have to be permanently flooded for its cleaning function, ie it does not have to be permanently filled with fluid.
  • the purification stage thus essentially completely delivers the fluid to the storage/soak stage. This results in aerobic conditions in the cleaning stage, so there is a supply of oxygen to the foreign substances that are retained by the cleaning stage through the cleaning process. For example, there is a supply of oxygen to the coarser solids that are held back by the sedimentation section. Due to the aerobic conditions, the biodegradation and the biological conversion of the foreign substances in the cleaning stage are improved.
  • the drying stage of the cleaning stage is particularly important for the biological degradation of light liquids such as oils, fats and all other hydrophobic organic materials. While these float on top of the fluid and are therefore difficult for the microorganisms responsible for degradation to reach, the hydrophobic materials when they dry out form a film over the retained solids and over the filter fabric used. This increases the contact surface between the microorganisms responsible for degradation and the light liquids, which promotes degradation.
  • drying out creates a negative pressure that supplies the retained solids with atmospheric oxygen to further support aerobic biodegradation.
  • the fact that the cleaning stage dries up is particularly independent of the amount of foreign matter that has already been retained. More preferably, the cleaning stage falls over dry the membrane filter section.
  • the membrane filter section is arranged in such a way that this is hydraulically possible. Since the membrane of the membrane filter section has a filter effect, the cleaning effect remains independent of the fluid level, even if the cleaning stage runs dry.
  • the storage/seepage system also called buffer storage, is therefore particularly suitable for the intermediate storage or seepage of rainwater.
  • the storage/infiltration system can also be used in addition to an upstream cleaning facility. In this case, there is an overall higher cleaning performance, in particular for fine particles that can be settled and filtered off.
  • the storage/seepage system includes an inlet that feeds the fluid to the cleaning stage.
  • the fluid is fed to the cleaning stage via an inlet.
  • the inlet can include, for example, a canal, an inlet shaft or a canal system. Provision can be made for the storage/infiltration system to be connected to a municipality's sewage system.
  • the storage/infiltration system comprises a post-purification stage which is designed to clean the fluid of further foreign matter after it has been discharged from the storage/infiltration stage.
  • This post-cleaning stage cleans the fluid before it is discharged into the ground, the sewer system or the drainage ditch to seep away.
  • the after-cleaning stage is also particularly preferably integrated into the storage/seepage stage. Because the post-cleaning stage is integrated into the storage/infiltration stage, the storage/infiltration system does not require any additional space. More preferably, the post-cleaning stage is a biofiltration stage.
  • the storage/seepage system for intermediate storage of the fluid can comprise a tank with a drain.
  • the storage/infiltration system comprises one or more hollow bodies for keeping a volume in the ground free.
  • Storage/infiltration systems are usually installed underground in areas such as streets or parking lots. Due to the superstructure, the static loads on the storage/infiltration system are very high. In order to withstand these loads, the hollow bodies have grid-like struts and/or supports. This results in a high level of strength for the overall system, which allows it to be built over.
  • the fluid can flow through or flow around the hollow bodies due to the holes.
  • the storage/seepage system and/or the hollow bodies can be equipped with a casing made of fluid-permeable material, through which the temporarily stored fluid can seep into the ground in a defined quantity and speed.
  • the fluid-permeable material can be a fleece or a fluid-permeable, open-pored membrane.
  • the cleaning stage is designed to clean the fluid of solids, light liquids and/or dissolved substances.
  • the cleaning stage is designed to clean the fluid of solids, light liquids and/or dissolved substances.
  • Some of the foreign matter was organic material, e.g. leaves, bark and pollen, as well as inorganic material such as sand, rock and a wide variety of heavy metals such as copper, zinc or lead. Heavy metals can occur in precipitation water in dissolved form, but above all in particle-bound form.
  • Road traffic in particular, is responsible for a large proportion of the foreign substances contained in rainwater, with its input from e.g.
  • Solids can be removed from the fluid by means of density separation, for example. Substances that have a lower density than the fluid float up, while substances with a greater density sink and settled down. Another way of separating solids is filtration. When it comes to filtration, a distinction is made between depth filtration and cake filtration. With depth filtration, the solids are separated inside the filter material, with the solids contained in the fluid being adsorbed on the filter medium by adsorption. While in cake filtration solids are initially separated on a filter fabric due to their diameter. This is followed by further solids separation on and in the filter cake that forms.
  • the fluid can also be cleaned of light liquids such as mineral oil hydrocarbons, oils and petrol by means of density separation.
  • the fluid which is heavier than the light liquids, can be passed on by means of a corresponding design on baffle walls and the separated light liquids remain in the separation device.
  • Another way to separate light liquids is to use a coalescence separator. Here, the attachment and thus the separation of light liquids takes place on a corresponding fine-meshed coalescence fabric.
  • the removal of dissolved substances from the fluid can take place by means of sorption.
  • dissolved substances from the fluid accumulate on the surface of a sorption material.
  • organically dissolved substances and inorganically dissolved substances such as heavy metals can be removed by sorption.
  • an ion exchange surface can also be used to remove solutes, where the removal of solutes is based on an ion exchange process. For example, when heavy metals attach to the ion exchange surfaces, calcium ions can be released from the ion exchange surface.
  • the cleaning stage comprises a plurality of sections, with each section having a maintenance option. Due to the fact that the foreign matter is a mix of different types of contamination, the cleaning stage comprises several sections which, in combination, clean the fluid of the foreign matter.
  • the sections can what their cleaning performance and cleaning principle concerned, must be matched to the foreign substances to be expected. Different physical and chemical-physical mechanisms of action can be used.
  • the storage/infiltration system Due to the modular structure of the cleaning stage, the storage/infiltration system is very flexible and can meet different requirements.
  • Each section has a service facility, so that access for maintenance of the sections is guaranteed. For example, a maintenance opening can be provided for each section, or a section can be maintained via the inlet or outlet of the section. For example, the retained solids can be sucked off or removed due to the maintenance option.
  • a filter membrane can also be exchanged, for example.
  • the cleaning stage comprises, in addition to the sedimentation section, a sorption section and/or a membrane filter section.
  • the sedimentation section is designed to retain sedimentable solids. The solids settled in the sedimentation section as sediment on the bottom of the section. During maintenance, the sediments can be sucked off or removed via the maintenance option.
  • the sorption section is designed to hold back light liquids and very fine particulate solids, preferably in the size range of less than 1 ⁇ m, particularly preferably in the size range of less than 0.63 ⁇ m, and dissolved substances.
  • the sorption section serves to separate the sedimentation section from the membrane filter section, so that no coarser foreign substances or those with a smaller quantity reach the membrane filter section, which then have a negative effect on the service life.
  • the sorption section can comprise a filter layer, for example a sorption substrate for removing heavy metals.
  • the sorption section is preferably constructed in several layers in order to meet different requirements. For this purpose, the sorption section is constructed in several layers from different filter layers.
  • the sorption section includes, for example, a layer of coalescing fabric, a layer of sorption fabric, and an ion exchange surface.
  • the sorption section can be serviced by the possibility of maintenance checked and/or exchanged.
  • a sorption section is also integrated in the sedimentation section.
  • an oil separator can be integrated in the sedimentation section.
  • a further separation of light liquids can then take place by means of coalescence fabric.
  • the sorption section is also connected downstream of the storage/infiltration stage. This should then, for example, enable further biological treatment of the fluid by means of biofiltration.
  • the cleaning step may include a membrane filter section to remove other foreign substances by means of a membrane.
  • the membrane should be designed in such a way that foreign substances that cannot be removed by settling and/or filtering are effectively removed from the fluid.
  • foreign matter in the size range of less than 0.63 ⁇ m In particular, foreign matter in the size range of less than 0.63 ⁇ m.
  • the pores of the membrane must therefore be designed in such a way that foreign matter in the size range of less than 0.63 ⁇ m can be separated.
  • the foreign matter that is separated out must not lead to a blockage, i.e. an excessive hydraulic influence on the membrane. Cleaning, preferably by rinsing, must also be possible.
  • the purification stage particularly preferably comprises a sedimentation section, a sorption section and a membrane filter section.
  • the cleaning stage is not only designed to dry out while maintaining functionality, but according to a preferred development of the invention it is also provided that the cleaning stage is designed to receive the fluid for temporary storage.
  • the cleaning stage is designed to receive the fluid for temporary storage.
  • a preferred development of the invention provides that the cleaning stage is designed in such a way that the foreign matter is removed from the cleaning stage be held back. In particular, this means a sustained retention of the foreign matter.
  • the cleaning stage is therefore designed in such a way that, when fluid is introduced again, the previously sedimented solids are not remobilized, or the adsorbed substances are not dissolved again. Remobilization during drying is also prevented in order to prevent the foreign substances from being transported further.
  • the sorption section upstream of the membrane filter section preferably ensures that foreign substances from the sedimentation area do not get into the membrane filter section during the drying process.
  • a preferred development of the invention provides that flow-inhibiting structures are provided in the inlet and/or in the cleaning stage.
  • the inlet and/or the cleaning stage are therefore equipped with mechanical or structural elements that reduce the flow of the fluid. This ensures that the flow is low enough so that foreign matter in the cleaning stage, in particular solid matter that has already settled, does not remobilize.
  • the flow-inhibiting structures have an influence, for example, on the inflow geometry of the cleaning stage, so that there is a defined inflow without turbulence.
  • the flow-restricting structures can be, for example, flow dividers, baffles, baffles or mud walls. These internals are used for the hydraulic and qualitative optimization of the inflow and/or the cleaning stage.
  • obstacles can be provided in the inlet and/or in the cleaning stage, which impede the flow rate of the fluid. This can be grooves, elevations, depressions or similar roughness.
  • the post-cleaning stage is designed to dry out and/or that the post-cleaning stage is designed to essentially drain the fluid completely to the ground, the sewer system or the drainage ditch.
  • the post-cleaning stage is designed to receive the fluid for temporary storage.
  • the fluid is thus cleaned of foreign matter before it is temporarily stored in the storage/seepage stage and then discharged into the surrounding soil or into a sewer system.
  • the process effectively protects the storage/infiltration system from colmation and remains efficient over the long term.
  • the cleaning of foreign substances from the fluid in the cleaning stage includes cleaning of the fluid from solids, light liquids and/or dissolved substances.
  • the method thus cleans the fluid of various foreign substances.
  • the process can be used very flexibly, since it can be adapted to the expected foreign matter.
  • the cleaning of the fluid from solids, light liquids and dissolved substances results in a particularly good cleaning performance being achieved with the method. With it the storage/infiltration system remains very well protected against colmation and is therefore functional for a very long time.
  • the method additionally includes the step of subsequent cleaning of foreign matter from the fluid in a post-cleaning stage. It is preferably a downstream cleaning in a biofiltration stage.
  • the downstream cleaning therefore takes place after the fluid has been temporarily stored in the storage/seepage stage and before the fluid has been discharged into the ground or into the sewer system. This enables a particularly good cleaning performance.
  • the method comprises the step of drying out the cleaning stage and/or substantially completely delivering the fluid to the storage/seepage stage.
  • This step creates aerobic conditions in the cleaning stage. So there is a supply of oxygen to the foreign matter that is held back by the cleaning stage. The aerobic conditions improve the biological degradation or conversion of the foreign matter in the cleaning stage.
  • drying out as a result of the sinking fluid level creates a negative pressure in the cleaning stage, which supplies the retained solids with atmospheric oxygen to further support the aerobic biodegradation. By drying out, the process ensures particularly good biological degradation of the foreign matter, which reduces the maintenance effort.
  • the method includes the step of receiving the fluid for intermediate storage in the cleaning stage.
  • the cleaning of foreign matter from the fluid in the cleaning stage includes retaining foreign matter in the cleaning stage.
  • retention means a sustained retention of the foreign matter.
  • FIG. 1 shows schematically a storage/infiltration system 1 according to the prior art.
  • the storage/infiltration system 1 is a multi-stage system in which a cleaning stage 2 precedes a storage/infiltration stage 3.
  • the contaminated rainwater is cleaned in separate stages that are not integrated into storage/infiltration stage 3.
  • the space requirement and maintenance effort of such a system is very high.
  • the figures 2 , 3 and 4 schematically show a storage/infiltration system 10 according to a preferred embodiment of the invention, wherein Figure 2b an enlarged view of a section Figure 2a shows.
  • the storage/infiltration system 10 comprises a storage/infiltration stage 12 which is designed to receive rainwater 14 for intermediate storage and to release it into a soil 16 surrounding the storage/infiltration system 10 for infiltration.
  • the storage/infiltration system 10 includes a cleaning stage 18 which cleans the precipitation water 14 of foreign matter 20, with the cleaning stage 18 being integrated into the storage/infiltration stage 12.
  • the storage/seepage system 10 has an inlet 22 which feeds the rainwater 14 to the cleaning stage 18 .
  • the volume in the ground 16 occupied by the storage/seepage system 10 is kept free by a plurality of hollow bodies (not shown).
  • the underside of the storage/seepage system 10 is equipped with a water-permeable fleece 24 through which the temporarily stored rainwater 14 can seep into the ground 16 in a defined quantity and speed.
  • the rainwater 14 can seep into the soil 16 not only on the underside but also on the sides of the storage/infiltration system 10 .
  • the cleaning stage 18 comprises three sections 26, 28, 30, each of which has its own maintenance option 32 available.
  • the first section 26 is a sedimentation section 26 which retains coarser solids 20 .
  • the solids 20 settled in the sedimentation section 26 as sediment on the bottom of the first section 26 .
  • sludge trap spaces or sedimentation spaces 25 formed by baffle walls 23 can be present at the bottom of the sedimentation section.
  • the sludge trap spaces or sedimentation spaces 25 ensure that the deposited sediment can stabilize against hydraulic influences and is not remobilized in the event of greater hydraulic loads.
  • it is possible to introduce additional elements to support the sedimentation process in the sedimentation section for example in the form of a lamella clarifier.
  • a lattice structure 27 with vertical 27a and horizontal 27b elements floating matter and light liquids are stabilized and are preferably firmly bound to cleaning elements.
  • the vertical 27a and horizontal 27b elements of the lattice structure 27 can be introduced independently of one another.
  • the second section 28 is a sorption section 28 which can be hydraulically flowed through either horizontally or vertically and which retains light liquids 20 and very finely particulate solids 20 and dissolved substances 20 .
  • the sorption section 28 is built up in several layers from different filter layers.
  • the sorption section 28 comprises a layer of coalescing fabric 34, a layer of sorption fabric 36 and an ion exchange surface 38.
  • the third section 30 is a membrane filter section 30 which removes further foreign matter 20 from the rainwater 14 by means of a membrane 40 .
  • the precipitation water 14 can pass through the membrane 40, while the foreign substances 20 are held back in the membrane filter section 30 due to the porosity of the membrane 40, due to the filter effect.
  • the cleaning stage 18 can dry out. This means that the cleaning stage 18 removes the rainwater 14 releases essentially all to the storage/infiltration stage 12 after a rain event ( figure 4 ). Furthermore, this also means that the cleaning stage 18 can absorb the rainwater 14 for temporary storage during a rain event ( figure 3 ). Thus, despite the integration of the cleaning stage 18 in the storage/infiltration stage 12, the storage volume is essentially the same size as in a storage/infiltration system with comparable dimensions and without a cleaning stage.

  • the method comprises five steps, although fewer or more steps are also possible.
  • the rainwater 14 When it rains, the rainwater 14 reaches the cleaning stage, where the rainwater 14 is cleaned of foreign matter 20 in a first step. In this step, the precipitation water 14 is cleaned of solids, light liquids and dissolved substances, with the foreign matter 20 being retained in the cleaning stage 18 .
  • the rainwater 14 then reaches the storage/seepage stage 12, where the rainwater 14 is temporarily stored in a further step.
  • the precipitation water 14 is also taken up in a further step for temporary storage in the cleaning stage 18 .
  • the volume of the cleaning stage 18 is therefore also available as a retention volume for temporarily storing the rainwater 14 .
  • the rainwater 14 is discharged from the storage/infiltration stage 12 to a soil 16 surrounding the storage/infiltration system 10 or into a sewer system.
