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 fil-ter 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 ce-ramic 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 econom-ic benefits,which will have a wide application prospect.%陶瓷过滤机是一种普遍采用的高效、节能、环保型固液分离设备。简述了陶瓷过滤机的工作原理，指出目前普遍使用的陶瓷过滤板存在易堵塞、难清洗、覆膜边角处易损坏漏气、清洗时会爆板等突出问题，介绍了新研制的可克服陶瓷过滤板所存在问题的新型复合有机过滤板的性能特点。通过试验表明复合有机过滤板在提高处理能力方面具有明显的优势，增产能力达14．85%，但在滤饼的脱水效果方面略逊于陶瓷过滤板，滤饼含水率较陶瓷过滤板的高0．57个百分点。可见，复合有机过滤板有利于提高陶瓷过滤机的工作效率和企业的经济效益，具有广阔的推广应用前景。
