Flat plate ceramic membrane waste mud recycling method and ceramic membrane supporting body
The invention provides a plate ceramic membrane waste mud recycling method which comprises the following steps: step S1, repeatedly kneading and covering waste mud according to a sequence of kneading and covering, and adding water according to a ratio during the first kneading; s2, testing the water content; and S3, pugging the mixed pug after the moisture content test in the step S2 in a non-vacuum state, sieving, aging, and preserving moisture for later use. The raw materials of the ceramic membrane support body comprise the waste mud obtained by the flat plate ceramic membrane waste mud recycling method. According to the invention, the waste mud is repeatedly kneaded and covered after being added with water, so that the components of the waste mud are uniform, the particles are uniformly dispersed, and the waste mud can be reused as a composition raw material of the ceramic membrane support body, thereby realizing the reuse of the waste mud and avoiding subsequent environmental pollution and extra transfer cost caused by discarding of the waste mud; and the strength, porosity and pure water flux of the formed ceramic membrane support body all meet related requirements.
本发明提供一种平板陶瓷膜废泥重复再利用方法，包括以下步骤：步骤S1，按照先捏合后捂料的顺序，将废泥反复进行捏合和捂料，且首次捏合时按照配比加入水；步骤S2，测试含水率；步骤S3，将步骤S2中含水率测试后的混合泥料于非真空下练泥，过筛，陈腐，保湿待用。该陶瓷膜支撑体的组成原料中包含由前述的平板陶瓷膜废泥重复再利用方法获得的废泥。本发明中废泥加水后反复进捏合和捂料，使得废泥成分变得均一，颗粒分散均匀，可作为陶瓷膜支撑体的组成原料再利用，实现了废泥再利用，避免废泥丢弃引发的后续环境污染和额外的转移成本，且成型后陶瓷膜支撑体的强度、孔隙率和纯水通量均满足相关要求。
