Abstract: Ceramic filter is a kind of high efficient，energy saving，environmental friendly and widely used solid-liquid separation equipment.The working principle of ceramic filter is briefly described.Problems such as easily blockage，difficult to be cleaned，easily damaged in the coated flat，easily broken when cleaning，etc.that exist in currently widespread ceramic filter plate are pointed out.Characteristics of the new developed composite organic filter plate which is better than that of ceramic filter board are introduced.Experiments show that composite organic filter plate has obviously advantages in capacity，which can be increased by 14.85% compared with ceramic filter plate，while composite organic filter plate is slightly inferior to the ceramic filter board in dehydration，and its moisture content is 0.57 percentage points higher than that of ceramic filter board.Obviously，composite organic filter plate is beneficial to improve the work efficiency of ceramic filter and the enterprise economic benefits，which will have a wide application prospect.

Key words: Ceramic filter, Ceramic filter plate, Composite organic filter plate
