Anhand beigefügter Zeichnung soll die erfindungsgemäße Vorrichtung in der bevorzugten Form einer Schlitzkastenkaskade beschrieben werden·The device according to the invention should be based on the attached drawing can be described in the preferred form of a slot box cascade

Der Behälter 1, der am oberen und unteren Ende geschlossen ist, wird durch die Zwischenböden 14 und 21 in einen oberen Vorfiltrationsapparat 2, eine Begasungs- oder Entsäuerungskammer 3 und eine Nachfiltrationseinheit 4 unterteilt. Der Vorfiltrationsapparat 2 ist mit einer absperrbaren Rohwasserzuleitung 5 bzw. 5a ausgerüstet. Zum Zweck der sogenannten Trockenfiltration wird über eine absperrbare Leitung Oxidationsluft durch das Gebläse oder den Kompressor 6 zugespeist. Der Vorfiltrationsapparat enthält eine Schlammwasserrinne mit Schlammwasserrohr 9. Die Vor- bzw. Trockenfiltration erfolgt über das Filtermaterial 79 das auf einem Wasser und Luft durchlassenden Boden 8 aufliegt. Die Filtermasse 7 kann aus einer einzigen Schicht eines einheitlichen Filtermaterials, aber auch, wie in der Zeichnung angedeutet, aus mehreren Schichten verschiedener Filtermaterialien bestehen. Der Filterboden 8 kann als Düsenboden oder in düsenloser Form, wie in der Abbildung dargestellt, ausgeführt sein. Durch den Boden 14 führt ein absperrbares Abflußrohr 15. Unter dem Filterboden befindet sich ein Einlaß 12 für Spülwasser und ein Anschluß 13 für die Spülluft. Beide Zuleitungen sind versperrbar. Der Vorfiltrationsapparat 2 ist ferner mit Entlüftungseinrichtungen 10 und 11 ausgerüstet.The container 1, which is closed at the upper and lower ends, is divided by the intermediate floors 14 and 21 into an upper prefiltration apparatus 2, a gas or deacidification chamber 3 and a post-filtration unit 4. The prefiltration apparatus 2 is equipped with a lockable raw water supply line 5 or 5a. For the purpose of so-called dry filtration, oxidizing air is fed in via a line that can be shut off by the fan or the compressor 6. The prefiltration apparatus contains a sludge water channel with a sludge water pipe 9. The prefiltration or dry filtration takes place via the filter material 7 9 which rests on a floor 8 that allows water and air to pass through. The filter mass 7 can consist of a single layer of a uniform filter material, but also, as indicated in the drawing, of several layers of different filter materials. The filter base 8 can be designed as a nozzle base or in a nozzle-less form, as shown in the figure. A shut-off drain pipe 15 leads through the bottom 14. Below the filter bottom there is an inlet 12 for rinsing water and a connection 13 for the rinsing air. Both supply lines can be locked. The prefiltration apparatus 2 is also equipped with ventilation devices 10 and 11.

Das Abflußrohr 15 für das vorgereinigte Wasser wird der Begasungs- oder Entsäuerungskammer 3 zugeleitet und mündet oberhalb einer oder mehrerer Kaskadenreihen, die aus einzelnen übereinander angeordneten Schlitzkästen 33 aufgebaut sind. Der Zufluß zu den Kaskadenreihen ist mit Regelorganen 34 ausgestattet, die das Zu- oder Abschalten von Kaskadenreihen ermöglichen. Unterhalb der Kaskaden sammelt sich das begaste bzw. entsäuerte Wasser auf dem Zwischenboden 21 und fließt dann über das Trichterrohr 18 der Nachfiltrationseinheit 4 zu. Die Begasungs- bzw. Entsäuerungskammer 3 wird mit Luft oder einem sonstigen benötigten Gas über eine versperrbare Zuleitung mit Hilfe des Gebläses oder Kompressors 20 beschickt. Die Begasungs- bzw, Entsäuerungskammer trägt außerdem einen Auslad 16 für die gasförmige Komponente, der ebenfalls verschließbar ist.The drain pipe 15 for the pre-cleaned water is the gassing or deacidification chamber 3 and opens above one or more cascade rows that consist of individual Slotted boxes 33 arranged one above the other are constructed. The inflow to the cascade rows is equipped with regulating devices 34, which enable cascade rows to be switched on or off. The fumigated collects below the cascades or deacidified water on the intermediate floor 21 and then flows over the funnel tube 18 of the post-filtration unit 4 to. The gas or deacidification chamber 3 is locked with air or another required gas via a lockable Feed line charged with the aid of the fan or compressor 20. The fumigation or deacidification chamber also carries a discharge 16 for the gaseous component, which can also be closed.

Unterhalb der Begasungs- bzw. Entsäuerungskammer 3 befindet sich die Nachfiltrationsstufe 4, die mit einem für die Nachfiltration geeigneten Filtermaterial beschickt ist. Diese lagert auf einem für Luft und Wasser durchlässigen Boden Unterhalb des Bodens 23 befinden sich absperrbare Zuleitungen 25 und 26 für Spülluft und Spülwasser. Die Spülluft wird über die absperrbare Leitung 29 ins Freie entlassen. Die Nachfiltrationsstufe 4 ist weiterhin mit einem absperrbaren Reinwasserablauf 24 sowie mit einer Schlammrinne 27 und einem versperrbaren Schlammwasserablauf 28 ausgestattet.Below the gassing or deacidification chamber 3 is the post-filtration stage 4, the one for post-filtration suitable filter material is loaded. This is stored on a soil that is permeable to air and water Lockable supply lines are located below the floor 23 25 and 26 for rinsing air and rinsing water. The purge air is released into the open via the lockable line 29. the Post-filtration stage 4 is still with a lockable pure water drain 24 and with a sludge channel 27 and a lockable sludge water drain 28 equipped.
