摘要：
Domestic wastewater featured with high ammonia nitrogen content and low C/N ratio is detrimental for urban water environment. Various strategies have been developed to well address the impending issues, while conventional processing technologies are less efficient for denitrification. In this work, the improved biological denitrification method with merits in easy operation, low cost and high efficiency is developed, optimal processing parameters which finally render a high ammonia-nitrogen removal rate of 99.3% are determined. The overall findings may pave a way for the optimization of operation parameters using biological denitrification method and its practical applications in wastewater treatment, considering the beneficial attributes particularly in shortening technological process and decreasing floor area, simplifying operational management.
