摘要：

试验采用复合式厌氧反应器(HAR)后续接生物接触氧化工艺(BC)处理生活污水。在水温高于15℃,HAR运行31d后,HAR完成启动,HRT为6h,HAR的COD_Cr去除率达到60%以上;HAR出水经BC段处理,HRT为3.2h,出水COD_Cr平均小于40mg/L,SS小于12mg/L,BOD₅和氨氮小于15mg/L。试验结果表明,HAR—BC工艺在我国气候适宜的地区可用来高效地处理生活污水。

Abstract:

Hybrid anaerobic reactor(HAR), followed by biological contact oxidation(BC) technique, is used for treating domestic sewage. When HAR is under operation for 31 d and the water temperature is 15℃, the COD removal rate is up to over 60%. When outlet water is treated by biological contact oxidation, HRT is 3.2 h, the COD of outlet water is less than 40 mg/L averagely, SS less than 12 mg/L, BOD₅ and NH₃ less than 15 mg/L. The results show that HAR and BC techniques can be used for treating domestic sewage in areas where the climate is suitable.

Key words: hybrid anaerobic reactor, biological contact oxidation, domestic sewage
