Auswirkungen der Feststoffe im Abwasser auf die Denitrifikation

Jar tests and continuous tests were carried out to study the influence which the solid matter contained in effluents has on nitrogen removal. It became obvious that in addition to the dissolved organic carbon compounds the particulate organic substances also make a considerable contribution to denitrification. All preliminary treatment measures which aim at minimizing the solid matter load in the biological treatment stage will lower the level of nitrogen removal that can be attained
