  • 摘要: 采用硫化物沉淀化处理含铅废水,考察了Na2S投加量、反应初始pH等操作条件对铅离子去除效果的影响,以及硫化铅沉淀反应过程的动力学特征,并采用激光粒度分析仪对反应生成的硫化铅沉淀的粒径分布进行了测定。实验结果表明,S2-与废水中Pb2+之间的沉淀反应能较好地符合一级反应动力学特征;Na2S与Pb2+的最佳物质的量之比为3;最佳的反应初始pH为6~9。在最佳操作条件下,Pb2+的平均去除率为99.60%,反应出水中Pb2+平均浓度为0.13 mg/L,低于污水综合排放标准(GB8978-1996)中铅的排放浓度限值。反应生成的硫化铅沉淀的平均粒径为2.62 μm,具有较好的沉淀性能,能够通过沉淀的方式与废水分离。
    Abstract: The wastewater containing lead ion was treated with sodium sulfide precipitation process. Precipitation reaction kinetics of PbS and operation variables, such as Na2S dosage, initial pH of wastewater, were investigated. The particle size distribution was studied using laser particle size analyzer as well. The results showed that the precipitation reaction fitted well with first order reaction model. The optimal Na2S dosage ( molar ratio of Na2S/Pb2+) and initial pH of wastewater were 3 and 6~9, respectively. Under the optimal operation conditions, the Pb2+ removal efficiency of 99.60% was obtained, and the residual Pb2+ concentration was 0.13 mg/L after treatment, it was below the lead discharge limit of Wastewater Integrated Discharge Standard of China (GB8978-1996). The mean particle size of PbS formed in the precipitation reaction was 2.62 μm, which indicates that the PbS precipitation can be well separated from wastewater by sedimentation treatment.
