摘要
以废弃的柚子皮为原料,研究Zn Cl2改性后的柚子皮对经过Na2S沉淀法处理后废水Hg2+去除率以及最佳实验条件。实验结果表明,在p H为9,硫化钠加入量为0.36 g/m L,同时加入絮凝剂Fe SO4条件下,硫化物-改性柚子皮综合法去除废水汞实验的去除率达到96%以上,终末废水汞的含量平均为0.0378 mg/L,达到国家0.05 mg/L的排放标准。
Taking the waste of the grapefruit skin as the raw material,the Hg2 ＋removal efficiency and the best experimental conditions of the Zn Cl2 modified by Na2 S were studied.Experimental results showed that at p H 9,sodium sulfide dosage was 0.36 g / m L,while adding flocculant under Fe SO4 conditions,the removal rate of the removal rate of the wastewater by the comprehensive method of the sulfide and the modified grapefruit peel was 96%,the average content of mercury in the end of the waste water was 0.0378 mg / L,met the national 0.05 mg / L emission standards.
