摘要：

The　effect　of　magnesium　powder　addition　on　waste　activated　sludge　(WAS)　fermentation　under　the　condition　of　20°C　and　pH=10　was　investigated.　The　results　show　that　adding　magnesium　powder　does　not　affect　WAS　solubilisation,　but　can　enhance　volatile　fatty　acid　(VFA)　production,　and　the　optimal　addition　is　0.01　g　per　gram　TSS.　The　compositions　of　VFA　are　in　following　order　(from　big　to　small):　acetic　acid,　n-butyric　acid,　iso-valeric　acid,　propionic　acid,　iso-butyric　acid,　n-valeric　acid　for　any　conditions　investigated.　The　most　and　least　concentrations　of　ammonia　in　the　fermentation　liquid　are　achieved　when　adding　amounts　are　0.01　and　0　g/g,　respectively.　The　concentrations　of　phosphorus　in　the　fermentation　liquid　decreases　with　the　increase　of　the　adding　amounts.
