The invention relates to the technical field of sewage treatment, and discloses a novel lightweight high-porosity ceramic filter material and a preparation method thereof. Fly ash floating beads, coal gangue and diatomite are used as aggregates, hydroxymethyl cellulose is used as a binder, dolomite powder, a pore-forming agent and limestone are used as auxiliary materials to prepare the ceramic filter material, and carbon nanofibers are attached to the surface of the ceramic filter material. The filter material is strong in pollutant holding capacity, high in filter material utilization rate and slow in water head loss increase, the filter speed can reach 16m/h, the working period is more than 24h, and the periodic water yield reaches 800-1000m < 3 >/m3 and is 1.5-2 times of that of a quartz sand filter material under the same condition.
本发明涉及污水处理技术领域，本发明公开了一种新型轻质高孔隙率陶瓷滤料及其制备方法。以粉煤灰漂珠、煤矸石、硅藻土为骨料，以羟甲基纤维素为粘结剂并辅以白云石粉、造孔剂、石灰石制备陶瓷滤料，并在陶瓷滤料表面附着碳纳米纤维。该滤料纳污能力强，滤料利用率高，水头损失增加缓慢，在同样条件下滤速可达16m/h,工作周期24h以上，周期产水量达800‑1000m3/m3，是石英砂滤料的1.5‑2倍。
