摘　　要：本文从解决生产实际问题出发，总结了山东分公司氧化铝厂铝酸钠溶液中，碳酸钠的来源及降低途径，通过分析生产流程中。碳酸钠浓度降低前后的种分分解率变化，发现：1）当溶液中，碳酸钠浓度较低时，对种分分解率的影响不是很明显；2）当溶液中，碳酸钠浓度超过25g／1时，晶种分解随其浓度的升高，分解率明显下降；3）碳酸钠浓度在46．7g／1时，与浓度在23g／1相比，种分分解率下降了近16％；Summary： this from address production actual problem starting, summary has Shandong branch oxlaauon atu- minum factory aluminum acid sodium solution in the, sodium carbonate of sources and the reduced way, through analysis production process in the, sodium carbonate concentration reduced before and after of kind of points de- composition rate changes, found： 1） Dang solution in the, sodium carbonate concentration lower Shi, on kind of points decomposition rate of effect not is clear, 2） Dang solution in the, sodium carbonate concentration over 25G/1 Shi, Crystal kind of decomposition with its concentration of rise, decomposition rate clear declined; 3） sodium carbonate concentration in 46.7g/When 1, compared with concentrations in 23g/1, seeds ＇ rate fell by almost 16%;
