正交试验法优选对苯二甲酸回收条件

Orthogonal test for optimization of recycling conditions

通过酸析正交试验对回收TA的工艺条件进行了试验研究,在正交试验和方差分析中,发现酸析时废水的温度、加酸的浓度、加酸时的搅拌速度、加酸速度均对试验结果有的影响。对回收TA的主要性能进行了系统的测定。分别对两种不同浓度的废水进行酸析试验,考察了废水水质的变化对酸析的影响。

The paper has researched the influences that crystal conditions of acid eduction from sea-island fiber wastewater have on the quality of recovered TA. The orthogonal test and analysis of variance show that the temperature of the wastewater, the concentration of the acid added, the mixing speed of acidadding, and the speed of acid- adding, have effects on the results of the experiments when acid is precipitating. This research also probes into the mechanism of crystal in acid eduction through the system mensuration and analyses of the main performances of recovered TA. The paper has also researched some experiments of acid eduction of two kinds of wastewater with different concentration, and surveyed the influence that the changing of the wastewater quality has on the experiments of acid eduction.
