| 1 | Rapid aerobic granulation in an SBR treating piggery wastewater by seeding sludge from a municipal WWTP显示文摘Aerobic sludge granulation was rapidly obtained in the erlenmeyer bottle and sequencing batch reactor(SBR) using piggery wastewater.Aerobic granulation occurred on day 3 and granules with mean diameter of 0.2 mm and SVI_(30) of 20.3 mL/g formed in SBR on day 18.High concentrations of Ca and Fe in the raw piggery wastewater and operating mode accelerated aerobic granulation,even though the seed sludge was from a municipal wastewater treatment plant(WWTP).Alpha diversity analysis revealed Operational Taxonomic Units,Shannon,ACE and Chao 1 indexes in aerobic granules were 2013,5.51,4665.5 and 3734.5,which were obviously lower compared to seed sludge.The percentages of major microbial communities,such as Protect)acteria,Bacteroidetes and Firmicutes were obviously higher in aerobic granules than seed sludge.Chlorqflexi,Planctomycetes,Actinobactena,TM7 and Aridobacteria showed much higher abundances in the inoculum.The main reasons might be the characteristics of raw piggery wastewater and granule structure. | Jun Liu Jun Li Xiaodong Wang Qi Zhang Helen Littleton | 2017 | Journal of Environmental Sciences2017，29，1： | 14 |
