The paper introduced the current situation of directly liquidating deification coal to prepare effective catalyst. It analyzed the source of salinity wastewater produced during the process and studies how to reduce the amount of wastewater by improving catalytic section and equipment. The result showed that under the condition of improvement,the salinity wastewater produced during catalytic section could reduce 14. 5 tons per hour.%本文主要介绍神华煤直接液化制备高效催化剂工艺现状，对催化剂制备过程产生的含盐废水（催化剂废水）来源进行了分析，研究通过催化剂制备工段的操作优化及装置改进，降低催化工段废水产生量。结果表明，在该改进装置条件下催化剂制备工段产生的含盐废水量每小时降低14.5 t。
