E-co-MBBR process flow diagram
“E-co Box” is an integrated equipment based on the MBBR by inverting
the AAO process, clarifying the positioning of pre-denitrification zone,
anaerobic zone, anoxic zone and aerobic zone function, optimizing the
layout structure of sludge reflux system and nitrification liquid reflow
system, fully combination of the active sludge process and biological
contact oxidation method’s advantages, while reducing the COD and
strengthening the effect of nitrogen and phosphorus removal at the same
time. In the pre-denitrification zone, the nitrate and oxygen in the
pre-denitrification zone are completely removed to ensure the strict
anaerobic environment in the anaerobic zone, so that the efficiency of
phosphorus release from the anaerobic zone is greatly improved, the
efficiency of phosphorus uptake in the aerobic tank is fully improved.
By removing the nitrification solution into the anoxic tank, the
denitrification capacity of the reactor is further enhanced, and the
efficient removal ability of nitrogen and phosphorus is realized.
