摘要：

In　order　to　effectively　control　the　sludge　filamentous　bulking　in　A2O-BAF　denitrifying　phosphorus　removal　process　when　treating　domestic　wastewater,　the　effects　of　sludge　load　and　temperature　on　sludge　filamentous　bulking　were　investigated.　The　results　had　shown　that　the　problem　of　slight　sludge　filamentous　bulking　existed　when　the　sludge　load　was　less　than　0.30　kgCOD/(kgMLSS·d).　Serious　sludge　filamentous　bulking　got　easily　happened　when　the　sludge　load　was　higher　than　0.55　kgCOD/(kgMLSS·d),　and　sludge　filamentous　bulking　was　controlled　effectively　by　changing　sludge　load.　The　sludge　filamentous　bulking　also　occurred　when　the　temperature　was　decreased　in　winter,　but　the　settling　ability　of　activated　sludge　got　recovered　after　increasing　the　temperature　to　original　level,　and　the　sludge　filamentous　bulking　was　also　controlled　effectively.　©,　2015,　Chinese　Society　for　Environmental　Sciences.　All　right　reserved.
