摘要：

The　transformation　of　dissolved　organic　matter　in　sequencing　batch　reactors　was　investigated　by　treating　domestic　wastewater　in　an　SBR　with　different　operational　parameters.　The　impact　of　sludge　retention　time　(SRT)　was　mainly　analyzed　with　respect　to　the　characterization　of　effluent　organic　matter　(EfOM)　in　sewage　effluent　from　the　SBR.　The　results　revealed　that　humic-like　substances　with　molecular　weight　(MW)　of　650　Da,　1700　Da　and　2000　Da　were　accumulated　during　the　biological　degradation　process.　Medium　MW　(500~3000Da,　humic　substances)　and　large　MW　organic　materials　(＞10000Da,　SMPs)　were　transformed　into　low　MW　organic　materials.　The　molecular　weight　distribution　of　EfOM　in　sewage　effluent　was　rarely　impacted　by　SRT,　only　an　intensity　difference　in　MW　of　650　Da　and　20,　000　Da　was　observed,　which　means　that　a　longer　SRT　was　helpful　for　the　degradation　of　humic-like　substances　and　soluble　microbial　products　(SMPs).
