采用挂复合填料的淹没式H/O系统对生活污水进行处理, 提出了相应的工艺设计参数, 主体设计一体化,建立了一座100m³/d的小型分散式城市生活污水处理装置, 并探讨了生物膜的一些特征。长时间的运行表明, 该系统能有效地去除COD和BOD并可脱氧, 主要出水水质指标达标 (GB8978— 1996 ), 具有操作管理简便、处理效果稳定可靠、运行费用低和可实现自动控制等特点。

Submerged H/O system of complex extenders is used to treat the domestic sewage. The corresponding technique design parameter and the design of essential equipment's integration, are put forword. Some specific features of biological film are discussed. The long running of a scattered small size (100 m³/d) urban domestic sewage treating device shows that the system could get rid of COD, BOD and dioxide effectively; the discharged water quality could reach the standards GB8978-1996. The process is easy to operate and manage, having reliable treatment effect, low O/M costs and practical automatic control.
