摘要：
The performance of upflow anaerobic sludge blanket (UASB) process for the treatment of slaughterhouse wastewater, with and without dissolved air flotation (DAF) as pretreatment was evaluated. Working parameters for the DAF process were evolved by bench scale studies. The biochemical methane potential (BMP) of the raw wastewater, the float and the subnatant (from DAF) was evaluated by serum bottle techniques. Results revealed higher biodegradability of the fractions as compared to the raw waste. The operation of UASB reactor at 30 +/- 1 degrees C with pretreated waste was found to be technically feasible.
