The effects of nitrate concentration in the main anoxic zone on denitrifying dephosphatation capability were conducted based on modified University of Cape Town (MUCT) process. Meanwhile the relation between optimal nitrate concentration (Nopt) and influent C/N ratio was evaluated, in which the influent chemical oxygen demand (COD) concentration was stabilized at (290±10)mg/L, the influent total phosphorus (TP) concentration was stabilized at (7.0±0.5)mg/L. The results indicated that: (1) the nitrate concen... 相似文献

为研究无动力船舶锚泊在灾害天气下抵抗较强干涉力(风、流、浪)作用下产生能使其发生走锚的载荷,利用分离型建模方法,并通过各工况下受力分析,利用Matlab进行模拟计算,得出风力超过8 m/s、λ/L大于0.7、联合作用载荷超过3.7×104kg就要进行撤离行动,可为船舶抗灾工作人员、相关管理者、船员等提供参考。 相似文献
