电渗析法处理制药厂酸性氨基酸废水 总被引:9,自引:0,他引:9
用电渗析对制药厂酸性氨基酸废水进行了处理,结果表明:氨基酸和COD的脱除率均可达80%,低浓浅色废水经一级处理即可达排放标准,氨基酸的浓淡比可达20倍,浓水中氨基酸浓度可接近其饱和浓度。对废水中离子通过离子交换膜的极化现象和迁移性也做了研究。 相似文献

在硝酸铵生产过程中,由稀硝酸带入的水分在中和、蒸发及结晶过程中以一次蒸汽的形式排出,形成含有氨态氮及硝态氮的工艺冷凝液,这是硝酸铵生产的主要污水源。我公司120kt/a硝酸铵装置是1971年设计、1983年建成投产的,采用常压中和法和单效蒸发工艺,浓度为99%的硝酸铵熔融液送高塔喷淋造粒生产颗粒硝酸铵,但生产中产生的冷凝液氨氮含量高,既使公司环保压力大,又造成了产品的流失。2010年,我公司采用江苏华晖公司的电渗析法水处理技术对该硝酸铵装置的氨氮废水进行了治理。 相似文献

The ability of the rationalized SCLC model to correlate data on the salt effect in vapor-liquid equilibria is examined in this work. For a system consisting of two miscible solvents the effect of salt in altering the relative volatility is represented by the model with four adjustable binary interaction parameters. The model is shown to correlate vapor-liquid equilibria of several alcohol-water-salt systems satisfactorily. 相似文献

Glazed surfaces can be produced on the face of ware mode from practically any clay or shale having maturing temperature of cone 1 or more by coating the face of the ware with a slip containing sodium chloride. Various concentrations of salt in the slip have been used. Lower concentrations do not produce glazes but develop interesting surface and color effects. Metallic oxides may be used to produce variation in color of the glaze. This method shows promise as a means of securing salt glazes in kilns which have heretofore been considered impractical for salt-glazing purposes, although it has been developed only in the lahoratory stage at the present time. Sodium carbonate has also been used successfully. 相似文献
