Abstract
The efficiency of wastewater treatment practices can be significantly improved through the introduction of new microbial treatment technologies.Partial nitrification-denitrification,the key of which was the realization of partial nitrification,was considered to be one of the energy-economizing nitrogen removal processes.And the main factors of nitrification and denitrification are temperature,pH,oxygen content and so on.The experimental results showed that under the condition of temperature at 16.5% and pH =7.4,the removal efficiencies of NH4+-N (42.59% ) and TN (25.26% ) were the best in the there months,followed by the temperature of 11.5℃ and the removal efficiencies were the worst when the water temperature was 7℃.So the temperamental was a main factor of controlling partial nitrification.关键词
