Conductive ceramsite filler for bio-trickling filter and preparation method of conductive ceramsite filler
The invention discloses a conductive ceramsite filler for a bio-trickling filter. The conductive ceramsite filler comprises the following components in parts by weight: 40-50 parts of activated carbon powder, 20-30 parts of iron oxide powder and 30-50 parts of clay. The preparation method comprises the following steps: uniformly mixing the activated carbon powder, the iron oxide powder and the clay, standing for 20-30 hours, putting into a vacuum pug mill for treatment, standing the treated pug for 18-24 hours, granulating to obtain pug granules with the diameter of 8-12 mm, naturally air-drying and shaping the pug granules, drying again, and finally firing at high temperature to obtain the conductive ceramsite filler for the bio-trickling filter. The filler is low in raw material price, environmentally friendly and low in production cost, the prepared filler is high in specific surface area and porosity and has excellent conductivity and mechanical strength, and the problems that in the prior art, a conductive filler for a bio-trickling filter is insufficient in specific surface area and porosity and poor in adsorption performance are solved.
本发明公开了一种生物滴滤塔用导电陶粒填料，包括如下重量份的组分：40‑50份活性炭粉末，20‑30份铁氧化物粉末，30‑50份粘土。制备方法为：将活性炭粉末、铁氧化物粉末和粘土混合均匀，静置20‑30h后，放入真空炼泥机中进行处置，将处置后的泥料静置18‑24h后，造粒得到直径8‑12mm的泥粒，将泥粒自然风干定型后再烘干，最后进行高温烧制，即得生物滴滤塔用导电陶粒填料。该填料原料价格低廉又环保，生产成本低，制得的填料比表面积高、孔隙率高，并具有优良的导电性和机械强度，解决了现有技术中生物滴滤塔用导电填料存在的比表面积、孔隙率不够，吸附性能不佳的问题。
