Process and apparatuses for the aerobic biological purification of lightly organically polluted waste waters with simultaneous nitrification

摘要

A process and apparatuses are described for the aerobic biological purification of lightly organically polluted waste waters (effluents) with simultaneous nitrification. Such waste waters originate, e.g., from high-performance reactors known per se. The complete clarification of these waters is successfully performed by a downstream low-loadable reactor which simultaneously also permits a nitrification.
