Hi Georg,
there is a lot of stuff on the net on this, e.g.

- http://www.re-natur.de/

- www.earthlife.org.za/ghouse/gfiles/water/euro-3.htm Water Issues & Problem:
RBTS Section 3 Design and Construction - Horizontal Flow Systems

Project Submitted to The Faculty of the School of Civil Engineering of Purdue
University by Bill Leady 1997

also check under keywords rootzone system, reedbed filter, constructed wetlands

Most often they are planted (in Europe anyway) with Phragmites, Typha, Iris.
Phragmites tends to form monodominant stands but some other plants may survive
on the edges.
Schoenoplectus is also used.
Mentha aquatica is said to be good at removing pathogens.
Also if you have a pond behind the system you can cultivate duckweed for
compost/mulch/chicken feed. It's good at taking up NH4 and ortho-phosphates.
I can recommend the book: Bahlo & Wach (1996) Naturnahe Abwasserreinigung, 137p,
Freiburg, Germany (Bahl & Wach design systems in Germany, Wach is based at the
Energie- und Umweltzentrum in Springe-Eldagsen near Hannover)
and also:
Arbeitsblatt ATV-A 262
Grundsätze für Bemessung, Bau und Betrieb von Pflanzenbeeten für 
kommunales Abwasser bei Ausbaugrößen bis 1.000 Einwohnerwerte
Juli 1998, 10 Seiten, DIN A4
ISBN 3-927729-42-6
EUR 19,50

and "Infopaket 3 Pflanzenkläranlagen", an excellent compilation of pertinent
journal articles.
