By adjusting the distribution ratio of influent flow into anaerobic and anoxic zones, the removal efficiency of pollutants in low C/N(COD/total nitrogen)<3.5 municipal sewage using modified step feed process was analyzed. Keeping the following conditions unchanged: hydraulic retention time(HRT) 10 h, sludge retention time(SRT) 10—15 d, volume of anaerobic zone:volume of total anoxic zones:volume of total aerobic zones 4:9:9, when the actual efficiency obtained and material balance calculation results were u...
