Wastewater containing titanium pigment was treated by microfiltration membrane, Nanometer titanium can be purified and concentrated by use of microfiltration. Operational conditions were optimized and the model was built. Finally, the amount of wash water was reduced. Based on the above research, the whole set equipment was designed, which can meet the needs in a titanium industry with a capability of 500 ton per year. Backflush and automatic control were used in the equipment, which has been steadily run two years, has been widely adopted in titanium industry. The technology has been widely adopted in titanium industry.In the recent years, whole set equipment of ceramic membrane was increasingly used in the recovery of desired production from fermentation broth in China. A new membrane process integrated with pretreatment of flocculation or coagulation was exploited to recover Inosine. ZrO2 ceramic membrane was used in the work, and the average permeation flux could reach 150L/m2.h under pH value of 3, transmembrane pressure 0.1MPa, CFV 3m/s, and temperature higher than 70C. The recovery ratio of inosine is higher than traditional recovery method, although inosine degraded under acidic and high temperature condition.

Without going deeply into questions which are only indirectly connected with the subject of this book, we will simply say this: It would have been well if Monseigneur Bienvenu had not been a Royalist, and if his glance had never been, for a single instant, turned away from that serene contemplation in which is distinctly discernible, above the fictions and the hatreds of this world, above the stormy vicissitudes of human things, the beaming of those three pure radiances, truth, justice, and charity.

我们不必深究那些只间接涉及本书内容的问题,我们只简单地说,假使卞福汝不是保王党,假使他的目光从来一刻也不曾离开过他那种宁静的景仰,并且能超然于人世的风云变幻之外,能在景仰中看清真理、公正、慈善等三道纯洁光辉的放射,那就更美满了。
