Abstract
A functional ceramic material made from a raw material mixture which includes 0.1-0.5 wt % iron powder, 20-25 wt % bentonite, and a remainder of sludge (based on dry weight) which contains bacteria. To make the functional ceramic material, the raw material mixture is calcined at low temperature and anaerobic conditions. Use of the material for purifying a medium is also provided.

A functional ceramic material prepared by a method comprising:
- calcining a mixture of raw materials at 800° C. to 900° C. under an anaerobic condition, the mixture including:
- 0.1-0.5 wt % of iron powder, 20-25 wt % of bentonite, and the remainder being sludge, wherein the sum of the weight percentage of ion powder, bentonite, and sludge, where the percentage of the sludge is based on its dry weight, equal to 100%.
