| Abstract: | A biological denitrification experiment was carried out continuously over a long period by using sequencing batch reactor(SBR) to investigate the effect of mass ratio of carbon to nitrogen w(C/N) and sludge age on the simultaneous nitrification and denitrification(SND) at different temperatures.The results show that under the condition of pH 7.5-8,the reaction rate of total nitrogen is 1.25 mg/(L·h),and the removal efficiency of COD,ammonia nitrogen and total nitrogen is 60%,38% and 34% respectively when w(C/N) is 8 and sludge age is 20 d at(5±1)℃.The reaction rate of total nitrogen is 2.06 mg/(L·h),and the removal efficiency of COD,ammonia nitrogen and total nitrogen is 69%,77% and 52% respectively when w(C/N) is 8 and sludge age is 15 d at(10±2)℃.The reaction rate of total nitrogen is 3.78 mg/(L·h),and the removal efficiency of COD,ammonia nitrogen and total nitrogen is 86%,86% and 70% respectively when w(C/N) is 10 and sludge age is 10 d at(20±2)℃.The reaction rate of total nitrogen is 4.94 mg/(L·h),and the removal efficiency of COD,ammonia nitrogen and total nitrogen is 91%,93% and 85% respectively when w(C/N) is 10 and sludge age is 10 d at(30±2)℃. |
