Description

Neutralisationsanlage für saure Betriebsabwässer Es hat sich in wiederholten Fällen gezeigt, daß in galvanischen Anstalten heutzutage größere Mengen saurer Betriebswässer anfallen, als die bisher bekannten Neutralisationsanlagen mit Sicherheit bewältigen können. Hinzu kommt, daß die Unmöglichkeit räumlicher Ausdehnung oftmals den weiteren Ausbau der bereits bestehenden Anlagen verhindert.Neutralization plant for acidic industrial wastewater It has been repeated in Cases have shown that nowadays larger amounts of acidic process water are used in galvanic institutions incurred than the previously known neutralization systems can handle with certainty can. In addition, the impossibility of spatial expansion often makes further Expansion of the existing systems prevented.

Gegenstand der Erfindung ist daher ein Vorschaltgerät zu der Neutralisationsanlage nach dem Patent 1081. 837, durch dessen Einbau auch einem Anfall sehr großer Mengen saurer Betriebsabwässer wirksam begegnet werden kann.The subject of the invention is therefore a ballast for the neutralization system according to patent 1081.837, through the installation of which even very large amounts of acidic industrial waste water can be effectively countered.

Die Zeichnung stellt eine Ausführungsform des Vorschaltgerätes gemäß Erfindung dar.The drawing represents an embodiment of the ballast according to Invention.

Die Abwasser-Einlaufleitung 1 sowie die Leitung 2 für das flüssige oder pulverförmige Neutralisationsmittel sind im Pumpenbehälter 3 von unten auf Pumpensaugstutzen an einem Pumpenrohr 4 zu angeordnet.The sewage inlet line 1 and the line 2 for the liquid or powdered neutralizing agent are arranged in the pump container 3 from below on the pump suction nozzle on a pump pipe 4.

Innerhalb des Pumpenrohres 4 wird das Gemisch von Abwasser und Neutralisationsmittel hochgetrieben, durch die im Oberteil des Pumpenrohres angebrachten Sieblöcher ausgespült und zusätzlich mit Hilfe des darüber angebrachten trichterförmigen, gerillten Abweisbleches 5 zerstäubt. Damit erfolgt eine vollständige Vermischung von Abwasser mit Neutralisationsmittel unter Luftzutritt über dem Wasserspiegel. Sowohl die Pumpe über dem Pumpenrohr 4 als auch Pumpe 6 für das Neutralisationsmittel werden über eine PH-Regelanlage 7 gesteuert.Inside the pump pipe 4 the mixture of waste water and neutralizing agent is driven up, rinsed out through the sieve holes made in the upper part of the pump pipe and additionally atomized with the help of the funnel-shaped, grooved deflector plate 5 mounted above it. This means that wastewater is completely mixed with neutralizing agent, with air admitting above the water level. Both the pump above the pump pipe 4 and the pump 6 for the neutralizing agent are controlled by a pH control system 7.

Am Auslauf des Behälters ist ein mit Schwimmer betätigter Überlaufschieber 8 angebracht, der den Inhalt des Behälters unter gleichzeitiger Hebung des Wasserspiegels während des Mischvorganges staut. Von dort fließt das gemischte und vorneutralisierte Abwasser der im Hauptpatent beschriebenen Anlage ZU. At the outlet of the container, a float-operated overflow slide 8 is attached, which accumulates the contents of the container while the water level is raised during the mixing process. From there, the mixed and pre-neutralized wastewater from the ZU system described in the main patent flows.

1,5 Mit diesem Vorschaltgerät wird eine vollständige Abwasserklärung erreicht. 1.5 With this ballast a complete waste water treatment is achieved.
