A presplitting blasting techique was adopted in the excavation engineering of the thickener in Lizheng Ore Company of Anyang Iron and steel General Co.

安钢集团公司李珍矿业公司在浓缩池挖掘工程中采用预裂爆破技术。

In contiously running thickener, the sedimentary specificities of thickeningarea are different from those in precipitating column.

在连续运行的浓缩池中，压缩区的沉淀特性，有别于沉降柱试验中压实区的沉淀特性。

Analyze sludge movement in the course of the mud scraper in concentrated pond operating,changes the straight line trowel to the curve trowel,raises the mud scraper working efficiency.

分析浓缩池刮泥机运转过程中污泥运动情况,改直线刮泥板为曲线刮泥板,提高了刮泥机工作效率。

Experiment was carried out on the static settling and thickening of sludge water from water works, so as to provide basis and direction for the design of inclined plane thickener.

　对自来水厂排泥水分别进行了静沉和动态浓缩试验,以便为高效斜板浓缩池的设计和运行提供依据和指导。
