对含苯胺黑药废水的净化进行了相关研究,并通过红外光谱分析初步揭示相关机理。采用铜模拟废水螯合与聚硅酸铝铁混凝沉淀的方式处理苯胺黑药废水,在pH值为8.5,铜添加量为20 mg/L,聚硅酸铝铁添加量为150 mg/L的条件下,苯胺黑药、化学需氧量和总磷去除率可达86.7%,83.0%和88.3%。经处理后,废水pH值、COD、总磷以及铜离子残留浓度均达到直接排放的标准。为矿业污水的综合治理提供了相关参考。

Aimed to investigate the degradation characteristics of aniline aerofloat,which is widely used as a collector for mineral flotation in China. Removal aniline aerofloat from flotation wastewater was studied through chelate precipitation with copper and polysilicate aluminum ferric. Result shows that the removal rates of aniline aerofloat,chemical oxygen demand ( COD) ,and total phosphorus ( TP) of wastewater after treatment can be more than 86. 7%,83. 0% and 88. 3%,when the doses of copper sulfate and PSAF were 20 mg/L and 150 mg/L,and the pH value was 8. 5. The pH,COD,and residual concentration of copper ions of the wastewater after treatment,are up to the standards of direct emission. The mechanism of chelate precipitation was further examined,and infrared spectra shows that copper ions chelate with the two sulfur atoms of aniline aerofloat. This study provides a potential way in dealing with the comprehensive management of mining wastewater.
