  Pretreatment of feed-in water is essential for SWRO seawater desalination process.Most of membrane pretreatment prior to SWRO used organic membranes and few researches were focused on the inorganic membranes.In this pilot experiment,a UF ceramic membrane with a skin layer γ-Al2O3 was applied as a pretreatment upstream of SWRO in Jiaozhou Bay,the Bohai Sea.The effects of operating conditions including cross-flow velocity,transmembrane pressure (TMP),feed temperature and pH on the performance of the UF ceramic membrane were investigated.Several parameters such as turbidity,TDS and COD of the feed water as well as the permeate solution were measured.The results showed that operating conditions played a major role in the filtration flux and the UF ceramic membrane system was sueceasful in achieving stable permeability and consistent filtrate quality.

海洋防腐工程中受阴极保护金属构筑物表面的电位电流分布常常是不均匀的,而金属表面的电位电流只有在一定范围内才能使构筑物受到有效和适当的保护.尤其在复杂而庞大的海洋钢结构物(如滨海电厂钛管凝汽器)阴极保护系统的设计和监测较复杂,该阴极保护下电化学场的计算,对评价阴极保护效果,优化阴极保护设计有重要意义.本文采用电化学场中的拉普拉斯(Laplace)方程,使用有限元计算法用四节点四面体和合适的形状函数对

海底甲烷水合物生成模型的建立,需要对沉积物中甲烷的溶解度进行正确测算.虽然甲烷溶解性的相关问题已经有了较为深入的研究,但是对于海底环境下甲烷溶解度测算问题的研究才刚刚起步.本文通过测定海水深度,海底温度和地温梯度,结合实验获得的相平衡计算式,建立了水合物稳定带(HSZ)底部及其内部甲烷溶解度的测算方法,同时运用该方法对四个典型的甲烷水合物研究区域进行评估,求得了各区域甲烷气溶解度与深度的相关性,研
