In the wet-process phosphoric acid production from the Hubei phosphate ore, one of the bothersome problems is that potassium fluosilicate and sodium fluosilicate scales are liable to form on the filtration system owing to its high potassium and sodium content, which greatly restrains the application of Hubei phosphate ore.

本文首先采用人工冷却系统模拟湿法磷酸生产的真空过滤系统冷却过程，研究垢物的析出规律，实验结果得知：垢物的主要成分为氟硅酸钠和氟硅酸钾，氟硅酸钠首先析出，结构致密，其次是氟硅酸钾，最后是二水硫酸钙，氟硅酸钠对氟硅酸钾有很强的结晶诱导作用；然后在三种生产中常用的不同的材质钼二钛、聚氯乙烯和聚四氟乙烯表面进行结垢试验，发现聚四氟乙烯表面最不易结垢，而在钼二钛表面最易结垢。

Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.

结果表明：长期不施肥料的CK处理，土壤耕层结构致密，很少有孔隙发育，土壤微结构为结构较差的碎屑聚积状-沙粒聚积状；长期单施化学肥料，土壤颗粒未形成结构体，少孔隙，土壤微结构主要为斑晶胶凝状－细沙粒聚积状结构，土壤结构比CK处理优；长期施用有机肥或有机无机肥料配施的处理，土壤粗颗粒数量显著增加，结构疏松，孔隙量大，动、植物残体丰富，有铁锰结核和腐殖质的形成和微团聚体的发育，土壤微结构类型以MNPK处理最好，为胶凝紧实状－多孔状结构。
