摘    要:利用一体式膜生物反应器对生活污水的处理进行了研究。结果表明,出水COD稳定,平均COD去除率达96%以上;NH4+—N的去除率受pH影响较大,当硝化好氧段pH为6.5~7.0时,NH4+—N的平均去除率高达99%以上,当硝化好氧段pH为4.7~5.8时,NH4+—N的平均去除率降为85%左右;系统运行期间污泥的质量浓度先由启动时的6 g/L降低到5 g/L,而后随着系统的运行呈增长趋势,试验结束时增长到8.14 g/L;粘度不随系统运行而增大,而是呈下降趋势,最终稳定在2.1 mPa.s左右。

关 键 词:膜生物反应器  生活污水  硝化

Abstract:The treatment of domestic wastewater using submerged membrane bioreactor was studied.The result shows that the average removal rate of COD is more than 96% and the removal rate is stable.The removal rate of NH~+_4—N is influenced pH value greatly.The average removal rate of NH~+_4—N is over 99% when pH value is 6.5~7.0 in the nitration part.However,the average removal rate of NH~+_4—N decreases to 85% when the pH value is 4.7~5.8 in the nitration part.At the beginning of the experiment,the sludge mess concentration decreases from 6 g/L to 5 g/L,then increases with the running of the system and at last reaches 8.14 g/L.The viscosity of sludge is not increased with the sludge concentration;it is decreased gradually and then stabilized at 2.1 mPa·s.
Keywords:Membrane bioreactor   Domestic wastewater   Nitration
