摘　　要：介绍了在沉淀实验教学过程中,根据教学经验对沉淀教学实验装置的一些改进,增加了水力搅拌、改变进水方式、省去空气压缩泵、设置溢流通道、安装刻度尺等。改进后的沉淀设备结构紧凑、流程简单、操作方便,符合实际教学需要,在实验过程中,效果显著,有效地提高了沉淀实验课程的教学质量。This paper introduced a few improvements which carried out on the precipitation teaching experiment device in the course of precipitation teaching, increasing hydraulic agitation, changing the feed mode, leaving out air compress pump, setting the overflow channel, installing graduated scale, etc. These improvements are based on the experimental teaching experience. The improved precipitation teaching experiment device has the features of compact structure, simple process and convenient usage and according with the actual requirement of teaching, obtained remarkable effects in the process of student experiments and effectively promoted the teaching quality of the precipitation experiment course.
