纺织废水的处理：均相催化湿气氧化

我们进行了一系列的试验，并找出了在一定温度和压力下能提高纺织废水湿空气氧化反应速率的催化剂。废水的种类包括天然纤维脱浆废水，合成纤维脱浆废水和印染废水，实验结果表明：所有被试验的催化剂均能显著提高化学需氧量（COD）和总有机碳（TOC）去除率及COD和TOC去除量，在所有测试的催化剂中，铜盐的效果最好，盐溶液中的阴离子在催化过程中起着十分重要的作用。硝酸根离子的催化效果比硫酸根离子要强，同样地，硝酸铜的催化性能比硫酸铜要强。不同金属盐的混合物的催化性能要强于单盐的催化性能。

Homogeneous Catalytic Wet-air Oxidation for Treatment of Textile Wastewater

An extensive series of experiments was performed to identify suitable catalysts to increase the reaction rate of wet-air oxidation of textile wastewater at relatively mild temperatures and pressures.Wastewater types treated included natural-fiber desizing wastewater,synthetic-fiber desizing wastewater,and printing and dyeing wastewater.Experimental results indicated that all catalysts tested in this investigation significantly increased the chemical oxygen demand(COD)and total organic carbon(TOC)removal rates and total COD and TOC removals.Of all catalysts tested,copper salts were the most effective.Anions in the salt solutions played a role in the catalytic process.Nitrate ions were more effective than sulfateions.Similarly,copper nitrates were more effective than copper sulfates.A mixture of salts containing different metals performcd better than any single salt.
