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.
实验表明，ZrO_2膜处理肌苷发酵液的合适条件为pH=3、操作压力为0.1MPa、膜面流速3m／s、温度大于70度，此时可以获得平均渗透通量150L／m~2h，但由于酸性条件、高温下肌苷降解，导致肌苷收率有所降低，但仍高于传统肌苷提取方法得到的收率；为进一步提高肌苷得率，缩短提取工序，实验研究了絮凝剂预处理发酵液，解决碱性条件下由于蛋白析出导致膜污染加重的问题，研究表明采用CaCl_2絮凝并调节pH=11，可以获得平均渗透通量为180L／m~2h，肌苷得率大于95％；比较了三种肌苷提取工艺得到的产品质量，采用预处理与陶瓷南京工业大学博士学位论文膜分离结合的除杂工艺得到的粗昔质量与陶瓷膜分离、离子交换及活性炭吸附工艺生产的粗普质量相当，均优于传统的提取工艺；设计了每小时处理12一巧吨肌普发酵液的陶瓷膜成套装置，采用部分内循环的方式降低设备的能耗，简化了肌昔提取方式，提高了产品的收率和得率，由于减少离子交换和活性炭吸附，使得工厂废水排放量降低30一40%，降低酸、碱用量，有利于环境保护。
In this paper, the four suitable bactericide materials were selected, a large number of experiments on singleand built bactercides proved that, after built, some bactericides have better effect of sterilization than single bactericides, thesterilizing rate was 99.99％ when the concentration of built bactericide 6601 was 20/mg · L－1, the number of coliform bac-teria was decreased from 1.2×108 CFV/L to 1.0×104 CFU/L.
