SBR工艺中DO和C/N对同步硝化反硝化的影响
EFFECT OF DO AND C/N ON SIMULTANEOUS NITRIFICATION AND DENITRIFICATION IN SBR TECHNIQUE
【摘要】 采用SBR工艺处理氨氮废水,研究不同的DO和C/N对同步硝化反硝化的影响,探索硝化反硝化一体化工艺的规律和特性.发现当DO=1.60~1.80mg/L、CODCr/CNH+4-N=6.5或BOD5/NH+4-N=4时,TN的去除率分别达到最大.
【Abstract】 Studied the effects of various DO and C/N on simultaneous nitrification and denitrification in treating ammonia nitrogen wastewater by SBR and explored the rules and characteristics of SBR technique. Discovered that the removal TN ratio was maximum when DO=1\^60~1\^80 mg/L, CODCr/CNH+4N=65 and BOD5/CNH+4N=4.
