Besides,the process presnts stability and fastreaction,high rate of recovery of lead from waste baffery sludge.

讨论了ＰｂＯ＿２还原过程的热力学问题，并对ＦｅＳＯ＿４＋Ｈ＿２ＳＯ＿４还原转化剂处理废蓄电池泥渣中ＰｂＯ＿２及Ｐｂ过程进行了试验研究，热力学分析及试验结果表明：本研究的还原剂将ＰｂＯ＿２和Ｐｂ还原转化为ＰｂＳＯ＿４的热力学推动力大，反应速度快，工艺过程稳定以及Ｐｂ回收率高。

This paper describes a new hydrometallurgical method for recovery oflead from waste battery sludge with K_2CO_3 as eliminating sulphur agent and the combi-nation reducing agent developed by us.

本文研究了一种从废蓄电池泥渣中湿法回收铅的新工艺，该工艺以Ｋ＿２ＣＯ＿３脱硫，以自研的复合还原剂还原，以氟硅酸作电解液电冶Ｐｂ。

A significant fraction of this material can be expected to remain in the steam generators,accumulating as sludge and fouling on the top of the tubesheet and tube support plates,free span tube surfaces,crevices between the tube support plates and the tube walls.

核电站在运行时,腐蚀产物和杂质会从二回路迁移到蒸汽发生器中,这些物质中有很大一部分将残留在蒸汽发生器内,成为泥渣和污垢,并逐渐在管板和支撑板上部、管子表面、支撑板与管子的缝隙内沉积。
