    摘要: The present invention is aimed at treating rainwater in a combined sewer system, while enabling removal of a majority of pollution substances even if a large amount of entering rainwater. The invention relates to a rainwater-treating apparatus in a combined sewer system, said apparatus comprising a plurality of upward flow type high-speed filter vessels each having a layer of a floating filter medium, a common treated water vessel which is located at upper faces of said high-speed filter vessels and is adapted to collect treated water from the high-speed filter vessels, a used wash water vessel which collects used wash water from said high-speed filter vessels, a rainwater inflow channel for distributing the entering rainwater into upper portions of the high speed filter vessels, and rainwater inflow portions for flowing downwardly the rainwater distributed from the rainwater inflow channel under the respective floating filter media of the filter vessels.

    摘要: It is an object of the present invention to provide a filtration system capable of achieving both uniform backwashing of floating filter media layer and efficient backwashing with low cost. The filtration system of the present invention comprises; a first filtration tank having a first floating filter media layer, a first upper screen with a first aperture ratio, the first upper screen being disposed over the first floating filter media layer and supporting the floating filter media, a first inlet for water to be treated disposed below the first floating filter media layer, a first backwash water supply source located over the first upper screen, and a first backwash water outlet means disposed below the first floating filter media layer; and a second filtration tank having a second floating filter media layer, a second upper screen with a second aperture ratio, the second upper screen being disposed over the second floating filter media layer and supporting the floating filter media, a second inlet for water to be treated disposed below the second floating filter media layer, an inflow blocking mechanism capable of blocking inflow of water to be treated through the second inlet for water to be treated, a second backwash water supply source located over the second upper screen, and a second backwash water outlet means disposed below the second floating filter media layer, in which the first aperture ratio is smaller than the second aperture ratio.

    摘要: Offenbart ist ein Filter, vorzugsweise für Teichanlagen und ein Verfahren zum Klären von Flüssigkeiten, mit einem Filter, in dem eine Vielzahl von Filterpartikeln aufgenommen sind. Die Durchströmungsrichtung ist entgegengesetzt der Kraft gewählt, die die Filterpartikel aufgrund ihres Dichteunterschieds zur zu klärenden Flüssigkeit erfahren. In dem Fall, in dem die spezifische Dichte der Filterpartikel größer als diejenige der zu klärenden Flüssigkeit ist, erfolgt dann eine Durchströmung entgegen der Schwerkraftrichtung von unten nach oben. In dem Fall, in dem die spezifische Dichte der Filterpartikel kleiner als diejenige der zu klärenden Flüssigkeit ist, erfolgt die Durchströmung umgekehrt von oben nach unten entgegen der Auftriebskraft.

    摘要: The present invention relates to a method for purifying contaminated water, comprising the steps of carrying the contaminated water in upward direction from below through a bed of granular material; and draining the purified water from the filter bed at a level located a determined distance from the top of the bed. Preferably the bed is further aerated, preferably from below. The invention also relates to an installation for carrying out the method.
