Media-filled wastewater treatment system for organic and ammonia nitrogen removal

摘要

The present invention relates to a system for simultaneously removing organic matter and ammonia nitrogen, and more particularly, to an wastewater treatment system, comprising: anaerobic and aerobic processes of removing organic matter using a honeycomb-mediad medium; Precipitation process; And a nitrification step of removing ammonia nitrogen by a carrier in which nitrifying microorganisms are comprehensively fixed. The present invention relates to a media-filled wastewater treatment system for returning a part of the treated water of the nitrification step to the anaerobic step. The present invention can maximize the simultaneous removal efficiency of organic matter and ammonia nitrogen by operating a four-step process of anaerobic → aerobic → sedimentation → nitrification.
