A pilot scale modified step-feed process was improved to increase nutrient（N and P）and organic removal operations from municipal wastewater.It combined the step-feed process and a method named "University of Cape Town（UCT）".The effect of nutrient ratios and inflow distribution ratios were studied.The highest uptake efficiency of 95% for chemical oxygen demand（COD）has been achieved at the inflow distribution ratio of 40/35/25.However,maximum removal efficiency obtained for total nitrogen（TN）and p...
