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.
