Biogas generated from sewage sludge,livestock waste,and food waste by anaerobic digestion is a valuable renewable energy ***,conventional anaerobic digestion is not an efficient process.A long hydraulic retention time and low biogas recovery rate hinder the applications of those *** effective pretreatment method to destroy sludge microbial cells has been one of the major concerns regarding improvement of the biogas *** article focuses on the effects of microwave heating on sludge anaerobic *** suspended solid(VSS) and chemical organic demand solubilization of heated sludge were *** heating was found to be a rapid and efficient process for releasing organic substrates from *** increase of organic dissolution ratio was not obvious when holding time was over 5 min with microwave *** effect of the VSS solubilization was primarily dependent on heating *** highest value of VSS dissolving ratio,36.4%,was obtained at 170°C for 30 *** COD dissolving ratio was about 2.% at 170°*** organic carbon of treated sludge liquor was 1.98 and 2.73 g/L at 150°C and 170°C for 5 min,respectively.A biochemical methane potential(BMP) test of excess sludge and a mixture of primary and excess sludge demonstrated an increase in biogas *** total biogas from microwave treated mixture sludge increased by 12.9% to 2..2. over control after 30 days of *** production was 11.1% to 2..9% higher for excess sludge than for untreated *** VS removal ratios of mixture sludge and excess sludge were 12. and 11% higher,respectively,compared to the untreated sludge.

该文通过水蒸馏法提取天祝祁连圆柏精油,采用GC-MS分析精油成分,并通过滤纸片熏蒸法和最低抑菌浓度(minimal inhibitory concentration,MIC)法、最低杀菌浓度(minimal,fungicidal concentration,MFC)法研究祁连圆柏精油的抑菌活性。结果表明,祁连圆柏精油得率为2.83%,从中共检测出47种化学成分,其中相对含量较高的物质为桧烯(19.59%)、α-杜松醇(11.81%)、(-)-4-萜品醇(10.90%)、γ-松油烯(5.55%)、香茅醇(5.06%)、萜品油烯(3.58%)、月桂烯(3.705%)、D-柠檬烯(3.34%)等物质。祁连圆柏精油对4种果蔬腐败真菌的抑菌活性存在显著浓度依赖性,对扩展青霉(Penicillium expansum)和硫色镰刀菌(Fusarium sulphureum)的MIC均为0.875μL/mL,MFC均为1μL/mL;互隔交链孢(Alternaria alternata)和粉红单端孢(Trichosporon roseum)的MIC均为1.12.μL/mL,MFC均为1.2.μL/mL。金黄色葡萄球菌(Staphylococcus aureus)和枯草芽孢杆菌(Bacillus subtilis)的MIC均为2.34μL/mL,最低杀细菌浓度(minimun bactericidal concentration,MBC)均为4.68μL/mL;粪产碱杆菌(Alcaligenes faecalis)和大肠杆菌(Escherichia coli)的MIC均为4.68μL/mL,MBC分别为4.68、9.36μL/mL。该研究表明祁连圆柏有较高的精油含量,精油成分丰富且对真菌和细菌均有较好的抑制活性,为祁连圆柏精油的开发和利用提供了依据。

对市购水稻秸秆生物炭的pH值、表面官能团、元素含量、比表面积、形貌特征进行系统表征,并采用振荡平衡法进行生物炭对水溶液中Cd 2.的吸附动力学和吸附等温线实验,探讨其吸附过程。结果表明:生物炭碳氧含量丰富;比表面积大且有大量无规则孔状结构;含有羧基羟基羰基等极性官能团;生物炭对Cd 2.的吸附分成快速和慢速两个阶段,在最初1 h内吸附量到达平衡量的93.3%,符合二级动力学模型;吸附量随温度的升高而增大,吸附过程为吸热过程;吸附等温线与Langmuir模型有较好的拟合性,生物炭对水中Cd 2.的吸附符合单分子吸附过程。上述结果为生物炭吸附水中镉提供一些参考。
