Abstract

The dirty water is passed through a reactor vessel in which plate packages, arranged in a meander fashion, are mounted as electrodes, of which the first is made of iron and the subsequent ones are made of aluminium. A complete plant for carrying out the process is described.

Description

Die Elektroflotation ist eine Kombination aus chemischer und physikalischer Wirkung. Bei diesem Verfahren werden Eisen- oder Aluminium-Anoden geopfert. Bei diesem Opfervorgang wird, ähnlich wie bei der chemischen Fällung, Eisen oder Aluminium als Oxyd zur Flockenbildung eingesetzt.Electroflotation is a combination of chemical and physical Effect. In this process, iron or aluminum anodes are sacrificed. In this sacrificial process, similar to chemical precipitation, Iron or aluminum is used as an oxide to form flakes.

Durch die elektrolytische Wirkung zwischen Anode und Kathode werden durch H2O-Trennung Feinst-Gasbläschen erzeugt. Der freigewordene Sauerstoff oxydiert äußerst intensiv die im Abwasser befindlichen Substanzen.Due to the electrolytic effect between the anode and cathode, very fine gas bubbles are generated by H 2 O separation. The released oxygen extremely intensely oxidizes the substances in the wastewater.

Die Flocken wirken ähnlich wie beim chemischen Fällungsverfahren. Die Feinst-Gasbläschen treiben die gebildeten Flocken an die Oberfläche. Es entsteht ein stabiles Schaumbett. (Das Schaumbett wird abgesaugt oder abge­ räumt.) Schmutzteilchen wie Sand und ähnliche schwere Partikel sinken und werden vom Bodenbereich aus abgesaugt oder abgelassen.The flakes work similarly to the chemical precipitation process. The Very fine gas bubbles drive the flakes formed to the surface. It a stable foam bed is created. (The foam bed is vacuumed or vacuumed clears.) Dirt particles such as sand and similar heavy particles sink and are vacuumed or drained from the floor area.

Zwischen der Schaumflocke oben, und dem Schwerschmutzanteil unten, ent­ steht die Klarphase.Between the foam flake at the top and the heavy dirt content at the bottom is the clear phase.

Durch die vorbenannten Wirkungsweisen wird das Abwasser:The wastewater becomes:

  • - geklärt- clarified
  • - erhält einen Stripp-Effekt- gets a stripping effect
  • - erhält einen Desinfektions-Effekt- gets a disinfection effect
  • - die CSB- und BSB-Werte werden erheblich verbessert- The COD and BOD values are significantly improved
  • - Metalle werden ausoxydiert- Metals are oxidized
  • - Emulsionen werden gebrochen- Emulsions are broken
  • - Öl-Anteile werden in die Schaumphase getrieben- Oil components are driven into the foam phase
  • - Entfärbung tritt ein.- Discoloration occurs.

Die Flockenentstehung ist im Bereich von pH 3,5 bis pH 10 möglich. Die pH-Korrektur (falls erforderlich) wird entweder vor, oder nach dem Elektroflotations-Verfahren vorgenommen.Flake formation is possible in the range from pH 3.5 to pH 10. The pH correction (if necessary) is done either before or after the electroflotation process.

Der Chemikalieneinsatz ist bei den häufigsten Wässern nicht erforder­ lich. Bei notwendigem Chemikalieneinsatz kann die Menge in geringsten Grenzen gehalten werden.The use of chemicals is not required for the most common waters Lich. If chemicals are required, the amount can be minimal Limits are kept.
