对复配药剂用于生物法制备1,3-丙二醇废菌液的絮凝沉降处理进行了研究,并与聚合硫酸铝、生物聚合铁进行了比较。结果表明:聚合硫酸铝没有絮凝沉降效果,在pH=9.0条件下,复配药剂投加量10 mL/L、生物聚合铁投加量8mL/L,处理效果较好。投... 对复配药剂用于生物法制备1,3-丙二醇废菌液的絮凝沉降处理进行了研究,并与聚合硫酸铝、生物聚合铁进行了比较。结果表明:聚合硫酸铝没有絮凝沉降效果,在pH=9.0条件下,复配药剂投加量10 mL/L、生物聚合铁投加量8mL/L,处理效果较好。投加助凝剂聚丙烯酰胺有助于提高上清液的透光率。 展开更多

The antibacterial effects of waste liquor of essence oil extraction from Sabina vulgaris Ant on Escherichia coil, Staphylococcus aureus, Salmonella, Bacillus subtilis, Bacillus magaterium and Bacillus cereus in foods ... The antibacterial effects of waste liquor of essence oil extraction from Sabina vulgaris Ant on Escherichia coil, Staphylococcus aureus, Salmonella, Bacillus subtilis, Bacillus magaterium and Bacillus cereus in foods were evaluated by paper disk method. The results showed that the waste liquor of essence oil extraction from S. vulgaris had inhibitory effects on E. coil, S. aureus and Salmonella with bet- ter inhibitory effects on E. coil and Salmonella; the bacteriostatic effect of water steam distillation waste liquor was better than that of water extraction waste liquor. The more times the waste liquor was distilled, the higher the active ingredients content was, and the better the bacteriostatic effect was. 展开更多
