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.

According to the practical needs of chrome-free tannage, titanium is abundant in nature, easily obtainable and ecologically friendly, titanium tannage can produce a leather with similar performance to chrome-tanned leather, so the research of titanium tannage to alternative chrome tannage was established as the research direction of this thesis. The preparation of novel titanium tanning agent, factors affecting titanium tannage, titannium tannage mechanism and titanium combining tannage were studied.

The weight percentage for the components of the hyaline coating is as follows: SiO2 45 to 54 percent, B2O3 15 to 20 percent, one or more of Na2O, K2O and Li2O, 10 to 24 percent, one or more of TiO2, ZrO2 and ZnO, 6 to 18 percent , and the rest is one or more of CaO, MgO and CeO2. Firstly, the glass powder is mixed with the mill additions to be pulped and then plated on the surface of titanium or the titanium alloy. After being dried, the surface of titanium or the titanium alloy is directly used for a thermal hydrogen treatment or smelted at a temperature of 900 to 1, 000 DEG C for 15 to 30 minutes and then a hyaline coating with a thickness of 20 to 70 micrometers is formed on the surface of titanium or the titanium alloy; secondly, titanium or the titanium alloy plated with the coating is conducted a thermal hydrogen treatment. After the treatment technique is finished, the coating flakes off automatically in the process of cooling; and finally, a surface treatment is supplemented to meet the requirement of the workpiece surface.
