NOVELTY - Iron-carbon filler for urine treatment comprises 50-80 pts. wt. iron powder, 20-30 pts. wt. carbon powder, 5-10 pts. wt. carbon fiber, 1-5 pts. wt. additives and 5-10 pts. wt. binder. The additive is bismuth sulfide and/or bismuth telluride. The binder is polyethylene and/or polyvinylidene fluoride. USE - The iron-carbon filler is useful for urine treatment. ADVANTAGE - The iron-carbon filler: has excellent galvanic effect; can realize continuous and automatic release of iron ions and maintain high-conductive paths inside and outside for long time without applying external electric energy; realize the elimination of nitrogen, phosphorus and nitrogen in urine wastewater. The method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing iron-carbon filler for urine treatment.
