催化湿式氧化处理香料废水

采用催化湿式氧化技术处理上海香料厂排放的高浓度有机废水。使用本实验室自制的催化剂，在中温（约１６０℃）和中压（约３．０ＭＰａ）条件下，试验了高浓度香料废水的湿式氧化行为。试验结果表明，香料废水经３０ｍｉｎ的湿式氧化处理，其ＣＯＤ、ＴＯＣ和色度的去除效率分别达到６９．１％、７４．８％和７９．５％。对香料废水湿式氧化处理前后可生物降解性能的试验证明，经３０ｍｉｎ催化湿式氧化处理后，废水的可生物降解性能     

PHASE SEPARATION AND MICROVOID FORMATION AT PHASE INTERFACES OF HYDROPHOBIC-HYDROPHILIC POLYMER BLENDS DURING WET PROCESSING

In this paper,morphological structure,thermodynamic compatibility and relationship be-tween porosities and blend ratios of the wet coagulated PU/PVA sheets were studied by meansof observation of scanning electronic micrographies,tests of dynamic mechanical properties,moisture regain and vapor permeability.Furthermore,the formation of microvoids at interfacesof separated phases was discussed and a microvoid formation mechanism at phase interfaces ofhydrophobic-hydrophilic blends was suggested and compared with that ofhydrophobic-hydrophobic blends.

Influence of Dispersion of Nano-Zn0 Particles in Polymer Matrices on Properties of Relevant Nano Composite Fibers

The surface-passivated and non-surface-passivated zinc oxide nano-particles （marked as s-nanoZnO and ns-nanoZnO respectively） were evenly dispersed in polymer solutions with the aid of ultrasonic vibration to prepare nanocomposite film by free casting and to prepare nanocomposite fibers by wet spinning and to prepare nancomposites coating by surface smearing. The dispersion of s-nanoZnO and nsnanoZnO in PAN matrix were observed by transmittance electron microscopy, the mechanical properties of the relevant compesite samples were studied by INSRTON tensile strength tester. It was found that s-nanoZnO behaves a well-dispersed morphology in PAN films and fibers when its concentration was 2 wt% but ns-nanoZnO nano particles agglomerate into larger congeries in PAN films. It means that the surface-passivated process oft zinc oxide nano. particles was effective to disperse. The relative intensity and elonsation at break of s-nanoZnO-PAN composite fibers show maximum values with the increase of nano particle content in compesites （from 0 wt% to 2 wt% of s- nanoZnO）. The elasticity of the composite fibers increases whereas their modulus declines. Balanced the changes of the properties mentioned above, 2 wt% s-nanoZnO in PAN matrix is a proper content for the composite fibers spun by wet spinning. The result of surface smearing test means that the reactim between s-nanoZnO and polymer can be indicated by the color of nanocomposite surface coat on fibers.
