膜生物反应器工艺参数控制研究

Study on the Technological Parameters Control of Membrane Bioreactor

以外压管式膜生物反应器和中空纤维一体式膜生物反应器处理城市污水试验为基础,对膜生物反应器工艺参数控制进行了研究。试验首次建立了曝气池容积与膜面积比的计算关系式,即V/A=J·S_O/N·X。验证了膜通量与污泥浓度的对数呈线性关系,污泥浓度愈高,膜通量愈低。还讨论了HRT和SRT对膜生物反应器生物性能以及出水水质的影响。

On the basis of membrane bioreactor experiment using external pressure bioreactor have been studied and discussed. The relationship between the volume of aeration tank and the surface area of membrane was first established, as V/A=J·So/N·X.. The linear relationship between the membrane flux and the logarithm of sludge concentration was tested and verified. The effects of SRT and HRT on the biological properties and the effluent quality were also discussed.
