摘　　要：采用一体化微滤膜生物反应器处理洗浴污水,探索影响膜污染的主要影响因素.研究结果表明,影响膜污染的主要因素是反应器的污泥质量浓度和水力停留时间,其次是水温,在曝气量不影响生物活性的条件下,气水比对膜污染影响较小.提高反应器污泥质量浓度可减缓膜污染.污泥质量浓度低于2g/L时,水力停留时间对膜污染影响较大,延长水力停留时间,膜污染速度减缓;污泥浓度达到4 5g/L时,水力停留时间对膜污染的影响明显降低,而且,单位水量膜阻力增值基本不变.水温升高,可减缓膜污染速度.An integrated membrane bioreactor is used for treating bath wastewater test and researching main factors to influence membrane pollution.The test indicates that sludge consistency and hydraulic remain time are main factors to affect the pollution,water temperature comes second,and the rate of air flow and water flow affects slightly the pollution under the air quantity enough to keep microorganism alive.Bigger sludge consistency can low down membrane pollution.Hydraulic remain time heavily affects the pollution with sludge consistency under 2?g/L.Longer hydraulic remain time makes lower membrane polluting velocity and then lightly with sludge consistency 45?g/L,which makes increasing value of membrane resistance same.High water temperature makes lightly membrane polluting.
