维生素B1制药废水的铁炭微电解-混凝预处理工艺

针对维生素B1制药废水高有机物浓度、高悬浮物、色度高、难降解的特点,采用铁炭微电解-混凝工艺对其进行预处理,效果良好。铁炭微电解-混凝工艺的最佳运行条件为:进水pH值为4,铁炭比为1∶1,曝气量为0.2m3/h的情况下停留时间80min。出水CODCr浓度平均为1600mg/L,去除率约为79%,色度去除率为85%,出水达到了(GB8978-1996)二级排放标准。

广州市32种水产品的Se含量特征分析

通过酸消解,原子荧光-氢化物发生法测定了广州市部分市售水产品中Se的含量,由标准物质(GBW 08551猪肝)和回收率控制检测质量.结果表明,不同水产品中Se含量有较大差异,含量范围为(34.-1117.)×10-9,平均含量为(345.±149.)×10-9,不同类型水产品中Se含量变化特征是:甲壳类(544.±107.)×10-9＞海水鱼类(392.±86.)×10-9＞软体类(244.±89.)×10-9＞淡水鱼类(238.±97.)×10-9.     

The 2006 war and its inter-temporal economic impact on agriculture in Lebanon

The July 2006 war waged by Israel on Lebanon caused an estimated USD 1 billion of direct (financial) damage to infrastructure. However, it generated also significant indirect (economic/inter-temporal) costs. One sector that suffered considerably in this respect was agriculture, the main source of income for 30–40 per cent of Lebanese. This paper's main objective is to develop a methodology to estimate the total—direct and indirect—cost of the war to agricultural crop production, using an area of south Lebanon as a focal point. The indirect loss assessment viewed inter-temporal reductions in crop production values as the opportunity cost of not working fields due to the presence of unexploded ordnance (UXO). Various crops were evaluated for two scenarios (50 and 100 per cent damage due to UXO) over UXO-clearance periods of five and 10 years. The results indicate that any damage estimates that include only direct losses will under-estimate total losses by 80 and 87 per cent for the five- and 10-year periods, respectively.

Effect of sulfate on the methanogenic activity of a bacterial culture from a brewery wastewater during glucose degradation

The maximum specific methanogenic activity （SMA） of a sludge originating from a brewery wastewater treatment plant on the degradation of glucose was investigated at various levels of sulfate on a specific loading basis. Batch experiments were conducted in serum bottles at pH 7 and 35℃. A comparison of the values indicates that the SMA of this mixed culture was increased and reached its highest level of 0.128 g CH4 gas COD/（g VSS.d） when biomass was in contact with sulfate at a ratio of 1：0.114 by weight.
