| 摘 要： | 试验采用超声/微电解联合体系处理含磷废水。以含磷废水为目标污染物,主要考察了温度、废水的浓度、反应时间、废水的初始pH、铁炭比和铁水比对废水中总磷去除效果的影响。在此基础上,挑选主要影响因素设计正交试验(L9(34)),得出反应条件的最优组合;超声辅助进行单因素对比试验,论证超声辅助能否大幅度提高除磷效果。结果表明,最佳的工艺条件为初始pH=4.00,反应时间60 min,铁炭体积比2:1,铁水体积比1/10,且在最佳条件下,总磷的去除率为77.3%,超声波技术联用后,总磷的去除率可高达92%以上。对比试验结果和动力学研究表明,超声波对微电解技术有良好的协同作用,协同因子E=2.25,且降解过程符合表观1级动力学规律。

| Abstract: | The synergetic treatment of phosphoric wastewater by ultrasound/micro-electrolysis was studied.The simulate phosphoric wastewater was considered as the main contaminant and the effects of temperature,reaction time,initial pH value of wastewater,Fe/C ratio and Fe/H2O ratio on the removal efficiency were investigated.The results showed that: the temperature and the concentration of wastewater little effect on the total phosphorus removal rate;the initial pH value,reaction time,Fe/C ratio and Fe/H2O ratio were... |
