摘　　要：通过实验室实验研究,得出在铅阳极泥生产工艺中,1#搅拌桶的控制参数为液固比4~5:1,温度40℃,搅拌时间不少于45min,并且要定期分析铅阳极泥二次洗水成分,通过补入新的生产水来降低溶液铅离子浓度。生产实践表明,按上述参数操作,铅阳极泥铅离子浓度可以控制到14%以下。Through the laboratory experimental research,the control parameters of 1#stirring bucket in the production process of lead anode slime are liquid-solid ratio 4-5:1,temperature 40℃,stirring time no less than 45 min,and the composition of secondary washing water of lead anode slime should be analyzed regularly,and the concentration of lead ion in solution can be reduced by adding new production water.The production practice shows that the lead ion concentration of lead anode slime can be controlled below 14%according to the above parameters.
