WATER TREATMENT SYSTEM AND METHOD FOR PURIFYING WASTE WATER FROM CULTURE TANKS FOR ANIMALS WHO LIVE IN WATER

摘要

The invention relates to a water treatment system and to a method for purifying water from culture tanks for animals who live in water. According to the invention, nitrification and denitrification can be carried out in a simple manner during a treatment step (50). This is achieved due to the fact that a reed bed (50) and a clarification pond (60), which is connected thereto on the outlet, are provided. The reed bed (50) comprises a reed chamber (53), which is filled with water which is to be treated, and a drainage area (55) which is arranged therebelow, in order to discharge the treated water, and at least one inflow (54) for water which is to be treated. The reed chamber (53) has a depth which comprises a predominantly anaerobic medium (532) in the lowest area of the reed chamber (53), for the denitrification thereof and the reed chamber (53) has the same-shaped layer as the deep profile.
