Silkworm excrement innocent treatment method

The invention discloses a silkworm excrement innocent treatment method. The method comprises the following steps of: building a silkworm excrement chamber by a silkworm raiser by taking a family as a unit, uniformly spraying the silkworm excrement by using diluent formed by microorganism bacterium agents per liter with 70 to 100 kg of water after matured silkworm mount cocooning frame and before silkworm excrement cleaning, so that each liter of microorganism bacterium agents can spray 360 to 450 kg of silkworm excrement; conveying the silkworm excrement spayed by the diluent to a silkworm excrement chamber provided with a rainproof top cover and a port for performing retting fermentation; thoroughly decomposing the silkworm excrement after the retting fermentation within 10 to 20 days, recycling the silkworm excrement under the required conditions, otherwise spraying the diluent on the newly generated silkworm excrement and adding the silkworm excrement into the silkworm excrement chamber, and performing ret
