Sewage nitrogen-phosphorus treatment process(DNR)

Sewage Field
This is a process that has added sludge denitrification, anaerobic, and anoxic conditions to previous
conventional activated sludge method in order to use the characteristics of microbe and to process
nitrogen and phosphorus biologically at the same time. By internally applying denitrification to nitrate
nitrogen contained in return sludge on the sludge nitrification tank, it can remove phosphorus effectively.
