一体式膜—复合生物反应器处理生活污水的试验研究

采用缺氧好氧复合生物反应器和中空纤维超滤膜一体式组合系统处理生活污水。结果表明：复合生物反应器能维持较低的悬浮污泥浓度而总生物量较高，这样可明显减轻对中空纤维膜的堵塞，并保持良好的生物处理效果。采用中空纤维膜进行固液分离可强化生物处理效果，尤其对ＳＳ，去除效果明显，出水悬浮物几乎为零，超过原厂三级处理效果，完全可作为油田回注水或其它加用水，是一项极具开发潜力的新工艺。

Study on a Compact Hybrid Bioreactor -- ultrafiltration MembraneSystem for Domestic Wastewater Treatment

Domestic wastewater was treated by a combined anoxic oxic hybrid bioreactor and hollow fiberultrafiltration membrane system. The results show that, hybrid bioreactor can remain low suspended sludgeconcentrationa and high total biomass, so that the membrane obstruction can be reduced. Solid -- liquid separation directly by hollow fiber ultrafiltration membrane can enhance the biological treatment, especially theremoval of SS. The effluent SS is nearly zero, better than the pressure filtered effluent used as the primewater of the oilfield from the in site sewage plant. It's a very promising process that needs to be developedfurther more.
