摘要
Abstract
In the fine filtration production of filter liquor of monazite alkali decomposition,the use of i-ron plate and frame filter had problems such as poor filtration effect,low automation level,and signif-icant temperature drop after filtration.Improvements were made to the existing fine filtration process,and the applicability of surface filter as fine filtration equipment for filter liquor of monazite alkali decomposition was studied.The results show that the surface filter with PP and PTFE membrane materials has a filtration retention rate of 93％after one hour,which is higher than the retention rate of the i-ron plate and frame filter.Compared with the iron plate and frame filtration,the surface filter has better fil-tration efficiency,higher automation level,and better solution insulation effect,which can be well applied in the fine filtration of filter liquor of monazite alkali decomposition.关键词
