NOVELTY - Municipal domestic sludge recycling method comprises mixing municipal sludge, mushroom dregs and plant waste at a volume ratio of 5-7:2-4:1-2, and adjusting water content of the mixture to 55-75%; mixing metal passivant and waste pile, and transferring waste pile to fermentation tank, fermenting, and ventilating constantly for 4-5 times a day (30 minutes each time); transferring the waste pile to rotating chamber, and fermenting for 15-30 days, where the water content is 35%; and breaking, sieving, adding raising agent in large grains, and sending back to primary fermentation.    USE - Method for recycling municipal domestic sludge to produce refined organic fertilizer (claimed).    ADVANTAGE - The method quickly treats municipal sludge, mushroom dregs and plant waste. The produced organic fertilizer has good and long effect and high utilization rate, improves the active soil, resists drought and disease, preserves water, and increases qualities, yields and performances of crops.    DETAILED DESCRIPTION - Municipal domestic sludge recycling method comprises:    (A) milling plant waste into 5-20 mm;    (B) mixing municipal sludge, mushroom dregs and plant waste at a volume ratio of 5-7:2-4:1-2, and adjusting water content of the mixture to 55-75%, where carbon/nitrogen ratio is 25-35:1;    (C) adding metal passivant, mixing the passivant and waste pile, transferring the waste pile to fermentation tank, fermenting, ventilating constantly for 4-5 times a day (30 minutes each time), and when temperature is 50 degrees C after 2 days, turning the waste pile, turning every 4-5 days during high temperature period, and when temperature is 40 degrees C, turning every 7 days, ventilating twice a day, and fermenting for 15 days;    (D) transferring the waste pile to rotating chamber, and fermenting for 15-30 days, where the water content is 35%;and    (E) breaking, sieving, adding raising agent in large grains, and sending back to primary fermentation.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic flow diagram of the method for recycling municipal domestic sludge (Drawing includes non-English language text).
