Abstract:
     This invention relates to harmless treatment of urban excrements and urine. At first, the excrements and urine mixture is solid-liquid separated and impurities are removed. Physicochemically catalytic and fermentable deodourizing agent are then added to convert the excrements-urine into compound organic fertilizer. It features shorter treating period and less investment (1/5 the investment of existing technology for a works to treat 100 ton excrements per day).
