Abstract：

Treatment　of　methanolic　wastewater　was　studied　in　an　anaerobic　sequencing　batch　reactor　(ASBR)　for　a　period　of　193　days.　The　results　showed　that　the　system　worked　efficiently　when　the　system　volume　loading　was　of　48g　COD/l.　d.　Both　Methanol　concentration　and　bicarbonate　play　an　important　role　in　the　anaerobic　conversion　of　methanol.　The　route　by　which　methanol　was　converted　into　methane　had　great　effect　on　the　COD　removal　of　system.　The　acetic　acid　utilization　rate　increased　with　the　volume　loading.　When　the　volume　loading　was　8g　COD/l.　d,　the　acetic　acid　utilization　rate　was　5%　and　the　COD　removal　was　over　95%.　While　the　volume　loading　was　12g　COD/l.　d,　the　acetic　acid　utilization　rate　was　15.83%　and　the　COD　removal　is　less　than　78%.　The　results　of　this　study　suggest　that　treating　methanolic　wastewater　using　anaerobic　sequencing　batch　reactor　is　feasible.　©　2011　IEEE.
