Multi stage sewage treatment using plants

Verfahren und Anlage zur Reinigung von Abwasser in Reinigungsstufen mit Hilfe von Pflanzen

Abstract

Method for treating sewage in a multi-stage process uses the combined actions of microorganisms in the sewage and vegetation beds, and stores sewage in a holding tank (2) from which it is pumped (11,12) to the first stage of the process. The novelty is, that the raw sewage is fed into a pre-treatment chamber (3) and is homogenised and aerated by being pumped (7) to the holding tank (2) and discharged (8) above the level (9) of sewage in the holding tank (2). Also claimed is a sewage treatment plant which uses the above method.
