摘要:
针对芬顿法处理成分复杂矿山废水中常因Fe2+消耗快、循环慢导致的药剂消耗大、易反色及稳定性差等问题，本研究将具有Fe2+络合能力的Na4P2O7引入芬顿体系，探究其对锡多金属选矿废水的强化处理性能。结果表明：Na4P2O7的添加使废水CODCr、Sb和SS的去除率分别提升9.6%、8.7%和8.3%。以CODCr去除率为指标，通过单因素试验考察了pH、m(H2O2)∶m(CODCr)、n(Fe2+)∶n(H2O2)和反应时间对其的影响。在m(H2O2)∶ m(CODCr)=3∶1的条件下，响应面优化得到最佳工艺参数为pH=3，n(Fe2+)∶n(H2O2)=1∶3，反应时间为29.8 min。沉淀物的SEM和XRD对比分析表明，添加Na4P2O7的芬顿体系沉淀物结晶度更高，结构规则且边缘清晰，主要成分为Fe(OH)3和钙磷石。推测Na4P2O7通过稳定Fe2+浓度促进Fe2+/Fe3+循环，从而强化芬顿反应性能。
Abstract:
Aiming at the problems of large agent consumption, easy to turn back and instability due to the fast consumption and slow circulation of Fe2+ in the treatment of complex mine wastewater by the Fenton method, sodium pyrophosphate possessing Fe 2+ complexing ability was applied into the Fenton process system to explore its enhanced performance in treating multi-metallic tin dressing wastewater. The results showed that the addition of sodium pyrophosphate increased the removal rates of COD Cr, Sb, and SS in the wastewater by 9.6%, 8.7% and 8.3%, respectively. Using the CODCr removal rate as the evaluation metric, single-factor experiments were conducted to investigate the effects of pH value, m(H2O2)∶m(CODCr), n(Fe2+)∶n(H2O2) and reaction time. Under the condition of m(H2O2)∶m(CODCr)=3∶1, the response surface optimization determined the optimal parameters as pH=3, n(Fe2+)∶n(H2O2)=1∶3, and a reaction time of 29.8 min. Comparative SEM and XRD analysis of the precipitates revealed that the Fenton system with sodium pyrophosphate produced precipitates with higher crystallinity, regular structure, and sharper edges, primarily composed of Fe(OH)3 and calcium phosphate. It is hypothesized that sodium pyrophosphate stabilized Fe 2+ concentration, thereby promoting the Fe2+/Fe3+cycle and enhancing the Fenton reaction performance
