摘要:
The invention relates to an anaerobic water purification system, conversion kit and method for treating a liquid. The anaerobic water purification system according to the invention comprises : - a container for the liquid for treatment provided during use with a sludge bed; - a supply conduit operatively connected to the container for supplying the liquid for treatment; - a distribution system connected to the supply conduit for distributing the liquid over the sludge bed from above; - carrier material which is arranged during use in the container and to which anaerobic sludge material can attach; and - a gas roof arranged at or on the container and provided with a volume which can be adapted during use to the biogas production. The carrier material is preferably free-floating material. The discharge conduit for discharge of treated liquid is preferably connected to a riser pipe.
