Definitions

  • a system for transferring incorrect discharges from a rainwater channel into a dirty water channel according to the preamble of claim 1 is known from DE-A-3636358.
  • the object is achieved by a system having the features of claim 1.
  • the invention takes advantage of the fact that a separating water system, which is connected to the sewage treatment plant, is routed parallel to the rainwater channel in separation systems. By removing the incorrect discharges from the rainwater sewer and transferring them into the sewage sewer, the sewage or waste water is extracted from the rainwater sewer and fed to the sewage treatment plant. To ensure that incorrect discharges into the sewage system are disposed of up to the receiving water faulty discharges should be transferred from the rainwater channel to the dirty water channel shortly before the receiving water.
  • the incorrect discharges are transferred into the latter due to a flow gradient between the rainwater channel and the dirty water channel.
  • This takes advantage of the fact that in a separation system the dirty water channel is always lower than the rain water channel and thus the dirty or waste water in the rain water channel can get into the dirty water channel due to the natural flow gradient.
  • the transfer of the incorrect discharges from the rainwater channel into the dirty water channel is to be regulated in such a way that the trickle water carried in the rainwater channel and the dirty water initially occurring during a rain event get from the rainwater channel into the dirty water channel. If a defined water level in the rainwater channel is exceeded, it is then shut off towards the waste water channel, and opened again when the water level falls below the defined level. This means that after the drainage or waste water has been drained off, the clean rainwater flowing through the rainwater channel in the event of a rain event is completely conducted to the receiving water. Only when the amount of rainwater decreases again does the transition to the sewage channel open, so that the remaining rainwater that accumulates at the end of the rain event is transported back to the sewage outlet.
  • the exact water level at which the rainwater channel to the dirty water channel is shut off depends on how much rainwater, ie water that is no longer contaminated with the dirt, should run out directly. In any case, the rainwater channel to the dirty water channel must remain open for so long that all water from the drain is transferred to the dirty water channel.
  • the dirty water channel is blocked off from the rainwater channel. If the rainwater channel to the dirty water channel is not closed off, water can thus pass from the rainwater channel to the dirty water channel, but not vice versa.
  • the connecting line should also be assigned a shut-off element that shuts off the dirty water channel towards the rain water channel.
  • the controller assigned to the connecting line advantageously has a throttle element which can be moved in front of the inlet opening of the connecting line and which is controlled as a function of the liquid level in the rainwater channel, in such a way that it fades the inlet opening more with increasing liquid level until it completely closes the inlet opening when the defined water level is exceeded. In this position, all water flowing through the rainwater channel reaches the receiving water via its outlet.
  • the throttle element can be designed as a throttle orifice which is connected to a float via a float arm.
  • the main function of the controller described is thus Throttling the connecting line to a defined value.
  • This freely defined value which depends on the performance of the waste water system, should be maintained until the closing value is reached.
  • the controller closes the connecting line until the tidal wave of the rainwater channel has expired.
  • the float measures continuously and opens the controller after the wave has decayed, expedient if the set amount of water is maintained until it fully opens.
  • the controller begins to open, water is discharged from the rainwater channel through the connecting line in the manner of a bypass to the dirty water channel. Due to the small opening and the relatively high water level, a high flow rate is achieved under the throttle element.
  • the bypass and the sump in front of the connecting line are cleaned, and after the regulator is fully opened, the floating materials are also rinsed off to the dirty water system.
  • the main function of the threshold is to divert the tap water to the connecting pipe.
  • the roof-shaped design results in favorable hydraulic conditions.
  • Another advantage of the threshold is its storage capacity. In the event of a short-term backwater in the dirty water channel and thus the connection line being closed, the water from the tap can be temporarily stored in dry weather and then drained off.
  • the threshold level is preferably adjustable.
  • the rainwater channel expediently has a shaft, the bottom of the rainwater channel being arranged above the shaft bottom and the rainwater channel inside the shaft having a lateral opening, the threshold in the region of the opening also being arranged obliquely to the extent of the channel in this and the shaft bottom is arranged at the same level as the sole of the inlet opening of the connecting line.
  • the sump is used to absorb the water from the drain before it is transferred, there is an acceleration of the heavy substances and thus keeping the sump and regulator clean, the sump is used to absorb the flushing impulse when it starts to rain and creates an intermediate buffer. The resulting pressure drop ultimately increases the flow rate in the connecting line.
  • a baffle is arranged between the rainwater outlet and the connecting line. Contaminants that reach the swamp during the start-up phase of a rain through the rainwater canal are removed through the connecting line. For floating materials or oil deposits, however, due to their specific weight, this is only possible with the top of the connecting line exposed. The floating materials in the shaft are swirled and discharged.
  • a baffle which can be designed to be fixed, removable, for example as a push-in wall, or as a floating baffle, the floating materials that have once entered the swamp zone are retained until the connecting line is opened and transported away by the latter.
  • the shut-off element associated with the connecting line is advantageously designed as a check valve. This must always form a secure seal between the dirty water channel and the rain water channel, regardless of the water level in the dirty water channel and the flow conditions when using an appropriate dirty water shaft.
  • a pump conveys the tap water via a line into the dirty water channel.
  • a check valve is expediently arranged in the flow connection from the pump to the dirty water channel.
  • FIG. 1 shows a shaft 1, to which a rainwater channel 2 is assigned, a shaft 3 to which a dirty water channel 4 is assigned, and a connecting line 5, which connects the shaft 1 and the shaft 3 to one another.
  • the two shafts 1 and 3 are closed by covers 6 and 7, the reference number 8 denotes the surface of the earth.
  • the bottom 9 of the rainwater channel 2 is located above the bottom 10 of the shaft 1.
  • the dirty water channel 4 is formed by a groove-like depression in the shaft 1, the bottom 11 of the dirty water channel 4 lies below the bottom 10 of the shaft 1.
  • An end wall 12 of the shaft 1 is provided with an opening 13 which forms the inlet opening for the connecting line 5.
  • the opening 13 is located below the base 9 of the rainwater channel 2 and coincides with the base 10 of the shaft 1.
  • the connecting line 5 runs at a constant slope to the shaft 3 and passes through the side wall 14 adjacent to the shaft 1.
  • the connecting line 5 projects partially into the shaft space 15, the opening of which is assigned to the shaft 3 and is located above the dirty water channel 4, e.g. closed by means of a shut-off valve designed as a check valve 16.
  • the Rainwater channel 2 which is designed as a tube outside the shaft 1 and is guided inside the shaft 1 in a channel bed 19, has a lateral opening 17 in the shaft 1, in the area of which, starting from the bottom 9 of the rainwater channel 2, a threshold 18 is arranged is, which extends obliquely to the longitudinal extent of the rainwater channel 2.
  • the threshold 18 serves to divert the water flowing upstream of the shaft 1 through the rainwater channel 2 into the sump 30 of the shaft 1.
  • a regulator 20 which is shown in detail in FIG. 10, is provided as an example for regulating or completely closing the opening 13 in the shaft 1.
  • This has a throttle diaphragm 21, which is guided above the channel opening 13 and is connected to a drive pulley 22, which are rotatably mounted on a common fixed axis 23.
  • a rope 24 runs over a second disk 25, which in turn is rotatably mounted on a fixed axis 26.
  • This axis 26 and the axis 23 are fastened to a common base plate 27, which in turn is connected to the end wall 12 of the shaft 1.
  • a float arm 28 is connected to the disk 25, the end of which, remote from the axis 26, receives a float 29.
  • FIGS. 1 to 4 and 6 have omitted the detailed illustration of the controller 20 and only the float arm 28 and the float 29 are shown. The upper end positions of the float 29 also differ.
  • FIG. 1 The conditions resulting from dry weather are illustrated in FIG. 1.
  • the incorrect discharges introduced into the rainwater channel, ie dirty and waste water, are transported through the rainwater channel 2 to the shaft 1.
  • the incorrect discharges are passed through threshold 18 into the sump 30 of shaft 1. Since the incoming incorrect discharges are so small in quantity that there is no liquid build-up in the sump 30, there is no floating of the float 29, so that the incorrect discharges reach the connecting line 5 through the open regulator and from there with a natural flow gradient to the check valve 16 over into the shaft 3, where they collect in the waste water channel 11 and are discharged to the sewage treatment plant.
  • little rain water initially passes through the rain water channel 2 and is diverted from the threshold 18 into the swamp 30 in the shaft 1.
  • a baffle 31 is additionally shown in shaft 1 in FIG.
  • the lower edge of the baffle 31 lies below the upper edge of the threshold 18.
  • the baffle 31 thus retains floating substances once they have reached the swamp zone, so that they can be safely transported away through the connecting line 5 after opening.
  • the reference number 31 alternatively designates an insertable baffle. It can be removed so that no second shaft opening is required.
  • a backlog in dry weather in the waste water channel 4 would inevitably lead to water pollution through the connecting line 5.
  • a check valve 16 closing the connecting line 5 is provided.
  • the regulator 20 itself offers a second protection, but not sufficient by itself.
  • a backflow from the dirty water channel 4 would raise the float 29 and force the regulator 20 to close. Only the slight difference between the upper limit value of the controller 20 and the upper edge of the threshold 18, which allows the throttle orifice 21 to open automatically, would also allow dirty water to reach the receiving water to a small extent.
  • the conditions of the backflow in dry weather are shown in FIG. 3.
  • FIG. 4 illustrates the conditions in a backwater in rainy weather. The processes described for FIG. 3 occur here. However, the controller 20 is activated from the side of the rainwater channel 2. Both sides of the connecting line 5 close up. Since the sewage channel 4 has a fault anyway, a transfer of rainwater is not useful.
  • FIGS. 8 and 9 illustrate alternative connection forms of rainwater channel 2 and dirty water channel 4.
  • the controller 20 is installed on the side facing away from the dirty water channel 4.
  • the connecting line 5 passes under the rainwater channel 2 and connects to the shaft 3 of the dirty water channel 4.
  • a common shaft 32 with a partition 33 is created for the rainwater channel 2 and the dirty water channel 4.
  • the controller 20 is assigned to the partition 33.
