| 摘 要： | 采用电絮凝技术处理洗车废水,以保证处理后出水能够循环利用。考察电流密度、初始pH值、NaCl浓度及电解时间等操作因素对COD与浊度去除效果的影响。结果表明,在最佳处理条件下,出水达到生活杂用水水质标准;另外,去除COD过程符合一级动力学模型,去除单位浓度COD产生4.02×10-3kg湿污泥、3.10×10-4kg干污泥。

| Abstract: | Electro-coagulation process is adopted to treat vehicle-washing wastewater for reuse.The effects of parameters(such as current density,initial pH, electrolyte NaCl concentration,electrolysis time,and so on) on the removal efficiency of COD and turbidity in the wastewater are studied.The result shows treated water could meet Water Quality Standard for Urban Water Consumption under these optimal conditions.Furthermore,the kinetic model for COD reduction agrees with first-order reaction kinetic model.Removing 1 mg/L COD could produce 4.02×10-3 kg wet sludge and 3.10×10-4 kg dry sludge. |
