Biological Nutrient Removal Method using a Submerged Moving Media Intermittent Aeration Reactor and System

摘要

The present invention for the removal of nitrogen and phosphorus in the inflow wastewater effectively in a single reaction vessel, is composed of a primary sedimentation tank (A), the anaerobic tank (B), an immersion type rotating media intermittent give (C) tank, the secondary sedimentation tank (D) and, in particular intermittently aeration tank (C), the deterioration in the outflow water quality due to the elimination of the excess biofilm to ensure that the film at the same time, microorganisms having a predetermined thickness by shear force caused by rotation to form that can be installed to secure a number of microorganisms to submerged rotating medium 10 the was designed to prevent.; Accordingly, the present invention can provide a driving condition capable of performing multiple reactors role in the existing process in a single reaction vessel, saving facility cost, maintenance costs, etc., at the same time artificially the environment for nitrogen, Inje removal and microbial activity a composition to effectively remove nutrients as zoom, and was even make it easier to keep the hydraulic overload of organic material by micro-organisms attached to the rotating media.
