Title
(DE) VERFAHREN UND VORRICHTUNG ZUM REINIGEN VON REGENABWASSER
(EN) METHOD AND DEVICE FOR THE PURIFICATION OF RAIN DRAINAGE WATER
(FR) PROCEDE ET DISPOSITIF DE PURIFICATION DES EAUX DE PLUIE
Abstract
(DE)
Verfahren zum Reinigen von Regenabwasser, insbesondere von Strassenabwasser, bei dem der Volumenstrom des Regenabwassers im Falle ausreichend grosser Regenspende zeitlich ein einen früher fliessenden ersten Teilstrom und einen zeitlich folgenden Teilstrom getrennt wird, wobei der überwiegende Teil des ersten Teil Stroms des Regenabwassers in zumindest ein Auffangvolumen geleitet wird, das hydraulisch stark vom Durchfluss des folgenden Teilstroms abgekoppelt ist, beide Teilströme einer Reinigung zugeführt werden und zumindest der aufgefangene Teilstrom durch ein Reinigungsverfahren von Verschmutzung getrennt wird, das leistungsfähiger ist als eine reine gravitative Trennung.
(EN)
The invention relates to a method for purification of rain drainage water, in particular, the run-off from roads, whereby the volumetric flow of the rainwater, during adequate precipitation, is divided into an early flow first partial stream and a subsequent partial stream, whereby the predominant portion of the first stream of rain drainage water is run into at least one collector chamber, with a good hydraulic separation from the subsequent partial flow, both partial flows are introduced into a purification and at least the partial collected flow is separated from contaminants in a purification method of greater separative capacity than a purely gravitational separation.
(FR)
Procédé de purification des eaux de pluie, en particulier des eaux de pluie tombées sur une chaussée, selon lequel le débit volumétrique des eaux de pluie est divisé dans le temps, en cas de pluies suffisamment fortes, en un premier débit partiel s'écoulant d'abord et en un second débit partiel subséquent, la partie prédominante du premier débit partiel des eaux de pluie étant acheminée dans au moins un réservoir collecteur fortement découplé hydrauliquement de la traversée du débit partiel suivant, les deux débits partiels sont acheminés vers un dispositif de purification et au moins le débit partiel collecté est séparé des impuretés par un procédé de purification qui est plus efficace qu'une simple séparation par gravitation.
