The polysilicic acid is compounded with polyferric chloride sulphate under certain conditions, then the polysilicic acid-polyferric chloride sulphate flocculence is prepared. The study shows that: when the Cl-/SO42-molar rate is 1:1, the Fe/Si molar rate is 2:1, the flocculence has the best effect on paper-making waste water treatment.

介绍了铅酸蓄电池化学反应原理和工作特性，分析了电池产生&硫酸化&的现象及原因，给出了解决&硫酸化&电池的处理步骤，同时也指出了预防产生&硫酸化&的方法。

The calcium sulfate was dissolved and led to the rapid increase of calcium ion concentration in the solution. So the calcium sulfate is not suitable for being seed crystal of low-salt concentration. The quartz sand and calcium carbonate both can be used as seed crystals, but it is much faster and more complete to use calcium carbonate as seed crystal compared with using quartz sand.

当硫酸钙加入处理液中发生了硫酸钙溶解现象，导致溶液钙离子浓度迅速增加，故硫酸钙不适合做低浓度盐水的晶种，而石英砂和碳酸钙均能对钙离子的结晶起到效果，但碳酸钙做晶种对钙离子的结晶更快捷、更彻底，在条件允许的情况下，采用碳酸钙做晶种为宜。
