| 摘 要： | 实验研究了投加硅藻土对膜生物反应器处理校园生活废水效果的影响。两组膜生物反应器的对比实验结果表明:投加硅藻土有利于MBR工艺中活性污泥的培养和出水的稳定。投加硅藻土使MBR的出水COD质量浓度稳定在25 mg/L以下,BOD5质量浓度小于5 mg/L,NH3-N质量浓度0.4 mg/L左右,TP质量浓度小于0.5 mg/L,SS未检出,出水水质更加稳定。

| Abstract: | The effect of dosing diatomaceous earth on the membrane bioreactor of campus wastewater treatment is studied.Compared with two sets of membrane bioreactor experiments,it is found that dosing diatiomeceous earth can improve the cultivation of activated sludge and effluent stability when the diatomaceous earth is added.The effect of the membrane bioreactor is better than that unadded diatomaceous earth.When the effluent of COD is less than 25 mg/L,BOD5 about 5 mg/L,NH3-N less than 0.5 mg/L,TP less than 0.4 mg/L,SS is not detected and the effluent is more steady. |
