摘要：

The removal of various organic constituents in municipal sewage was investigated using anaerobic fluidized sludge blanket (AFSB) and anaerobic filter (AF). Experimental results revealed that the AFSB reactor could treat the sewage more efficiently than the AF reactor and the removal efficiency of organic matter greatly varied in constituents. At hydraulic retention times in the range of 8 to 24 hours, 50% COD reduction and 59% TOC reduction can be achieved by the AFSB reactor at 37-degrees-C. Lipids, proteins and carbohydrates can be highly removed, but the removal efficiency of surfactants is very low under anaerobic conditions. Methane production was rather limited (0.12 m3/kg COD removed at STP) and the COD removal by sulfate reduction seems not to be neglected. The sludge production during 272 day operation times was 0.272 gVSS/g COD removed in the AFSB reactor.
