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。

A process for treating the sludge generated by alumina sewage treating system incldues such steps as pumping the alumina sewage in sand depositing pool then in depositing pool, mixing the bottom sludge, the sewage from sand-water separator, and the regenerated water from filter to obtain backflush water, heating in desilicating heater, washing the secondary red mud to recover Na2O and Al2O3, anjd returning the washing liquid containing Na2O and Al2O3 back to the flow of production of alumina.

本发明公开了一种氧化铝废水处理系统的污泥处置新工艺,它将氧化铝废水先进入沉砂池中进行沉砂处理后才进入沉淀池中,将虹吸泥机从沉淀池中吸出的底流污泥和砂水分离器分离出的污水以及将部分经过滤器过滤后所得的再生水作为反冲洗水一起通过污泥泵送到脱硅加热器中加热得污泥热水,然后将污泥热水用于二赤泥洗涤沉降,以回收赤泥附着的Na2O和Al2O3,将洗涤赤泥后含有Na2O和Al2O3的洗液送到氧化铝生产流程中重新使用。
