摘要
文章采用双功能膜-序批式生物反应器处理实际洗浴污水方法,在不排泥条件下考察了系统对污染物去除效果及膜污染的情况;结果表明,污染物去除效果良好,COD、可溶性正磷酸盐及浊度等平均去除率分别达到88.4%、90.0%和96.9%;膜组件对COD的强化去除作用不明显,但对浊度的强化去除作用显著;通过膜曝气可以使膜比通量具有一定程度的恢复,但膜过滤性能仍不稳定,膜污染发展速度较快,过滤周期较短;污泥浓度对膜过滤阻力上升速率影响显著。
The dual function membrane-sequencing batch reactor （DFM-SBR） was used to treat bath wastewater. The effect of pollutant degrading and membrane fouling were investigated without sludge discharge. The result shows that the removal efficiency of COD, soluble phosphate and turbidity has reached 88.4%, 90. 0% and 96.9% respectively. No evidently intensified COD removal by the micro porous tube membrane was observed. The micro porous tube membrane can enhance the removal of turbidity. By membrane aeration, membrane flux can be partly recovered, but the membrane pollution developed fast in the filtration cycle. The sludge concentration has a significant impact on membrane filtration resistance.
