生化法处理含氨废水动力学研究

Study on Kinetics of Ammonia-Containing Wastewater Treatment by Biochemical Method

对生化法处理含氨废水过程中有重要影响的动力学因素进行了试验研究和分析 ,得出了利用高效微生物菌群去除废水中COD和NH3 N的最佳动力学条件 :温度为 2 0～ 35℃ ,pH为 7～ 8,DO大于 2 .6mg/L ,MLSS大于 2 .6 g/L ,C/N小于 3。在此条件下处理含氨废水 ,处理后的出水达到国家化肥行业一级排放标准。

The major affecting factors in biochemical treatment of ammonia containing wastewater have been studied and analyzed.The optimum kinetic conditions for removing COD and NH 3 -N in wastewater by high-efficient bacteria are as follows:temperature 20～35℃,pH7～8, DO >2.6 mg/L, MLSS >2.6 g/L,C/N<3.After treatment under these conditions,the effluent can meet the first grade discharge standard for ammonia industry wastewater of China.
