| 英文摘要 | Five yeast strains, namely Rhodotorula rubra. Candida tropicnlis, Candida utilis, Candida boidinii. Trichosporon cutaneum, were isolated from soil spots of a salad oil factory, and applied for continuous treatment of salad oil manufacturing wastewater. me oil and COD removal performance of the mixed cultures were comparable to the results other researchers obtained. Sludge expansion, accompanied with sludge morphology change from pseudomycelia to true mycelia, occurred during continuous treatment of wastewater. The true mycelia dominated sludge had a much higher water content and SVI value than that of the yeast purr cultures, although the two kinds of sludge had similar oil removal performance. A mold, Geotrichum candidum, was isolated from the expanded sludge, and was suspected to be a reason for sludge expansion. Addition of 0.3% sodium propionate into batch cultures degraded SVI value from around 100 to 60. In a continuous running. addition of 10 mg l(-1) sodium hypochlorite decreased SVI value from over 200 to below 100. The yeast activity, however. was weakened to a large extent at the same time. |
