Process for the load-dependent control of nitrification and denitrification in wastewater treatment plants with upstream denitrification

摘要

The invention relates to a control method for sewage plants with upstream denitrification with at least one continuously operating nitrification zone using a blower for the dynamic use of the cascaded basin arrangement. An intermittent operation of one or more pelvis or pelvic sections is followed by several parameters, so that partial ventilation takes place in one section of a nitrification zone, while the ventilation in another section can be switched off depending on the load, the airflow of at least one blower being specifically dependent on the load of individual pelvis or pelvic sections is supplied.
