Definitions

  • the problem is solved in that the incorrect discharges are transferred from the rainwater channel into a dirty water channel.
  • the invention takes advantage of the fact that in the case of separation systems, a dirty water channel is guided parallel to the rainwater channel and is connected to the sewage treatment plant. By removing the incorrect discharges from the rainwater channel and transferring them into the dirty water channel, the dirty or waste water is extracted from the rainwater channel 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 due to a flow gradient between the rainwater channel and the dirty water channel are transferred into the latter.
  • the further development takes advantage of the fact that in a separation system the sewage channel is always lower than the rainwater channel and thus the sewage or waste water in the rainwater channel can get into the sewage 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 dirty 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.
  • a first preferred embodiment of a system for carrying out the method is characterized by a rainwater channel, a dirty water channel, a connecting line between rainwater channel and dirty water channel, with a flow gradient of the connecting line from the higher connection point in the rainwater channel to the lower connecting point in the dirty water channel, one in the area of the connecting line
  • the rainwater channel arranged positive or negative threshold for draining liquid into the connecting line, as well as a controller regulating the flow through the connecting line, which shuts off the defined level in the rainwater channel towards the dirty water channel and opens it again if the level falls below.
  • 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 the 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 shaft 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 positive or negative, i.e. formed as a gutter, the diversion of the tapping water to the connecting pipe.
  • positive or negative i.e. formed as a gutter
  • favorable hydraulic conditions result from a roof-shaped design.
  • Another advantage of the raised threshold can be seen in its storage capacity. In the event of a short-term backwater in the dirty water channel and thus the connecting line being closed, the resulting 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, the heavy substances are accelerated and the sump and regulator are kept 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 through the rainwater channel during the start-up phase of rain are transported away 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 assigned to 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 a corresponding dirty water shaft.
  • Another embodiment of the system for carrying out the method according to the invention is characterized by a rainwater channel and a dirty water channel, the rainwater channel having a shaft and a rainwater outlet and the bottom of the rainwater channel is arranged above the bottom of the shaft, and the rainwater channel has a lateral opening inside the shaft, a threshold in the area of the opening being arranged obliquely to extend the channel, and a pump is arranged at the bottom level of the shaft , which is connected to the dirty water channel via a line.
  • 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 element designed as a check valve 16.
  • the Rainwater channel 2 which is designed as a pipe 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 positive threshold 18 is used to divert the water flowing upstream of the shaft 1 through the rainwater channel 2 into the sump 30 of the shaft 1.
  • 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 non-return valve 16 over into the shaft 3, where they collect in the waste water channel 11 and are discharged to the sewage treatment plant.
  • 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 matter once it has reached the swamp zone, so that it can be safely removed through the connecting line 5 after it has been opened.
  • 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 diaphragm 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 situation with a backwater in rainy weather.
  • the processes described for FIG. 3 occur here.
  • 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.
