collecting earthworms when the density of the earthworms reaches 3-4 kg/1 square meter of bed area, collecting the earthworms intensively every 15 days until the sludge is added into the bed with the height of 35-40 cm and the density of the earthworms reaches 3-4 kg/1 square meter of bed area, spreading the bed when the earthworms are collected, spraying an attractant on a sponge to be placed on the bed, collecting the earthworms in a dark way by adopting an artificial method, collecting a surface layer 8-12 cm deep on the surface of a new bed on a plastic cloth, scraping a layer of earthworm feces with the thickness of 2-3 cm by utilizing the light-shielding property of the earthworms, returning the scraped earthworm feces and earthworm cocoons to an original bed, continuously breeding, downwards transferring the grown earthworms into a lower layer, continuously scraping a layer of earthworm feces with the thickness of 2-3 cm repeatedly after 8-10 minutes, and till the clean earthworms are collected;
4) expanding the bed and collecting the treated sludge finished product:
(1) when the bed is expanded, firstly, a new base bed is manufactured in another greenhouse according to the steps in the step 2) for standby, the high-density earthworm surface layer with the thickness of 10-15 cm at one side of the original base bed is taken away and paved on the new base bed by taking the center line of the original base bed as an axis, the paving area accounts for two thirds of the surface of the new base bed, the high-density earthworm surface layer with the thickness of 10-15 cm at the other side of the original base bed is taken away and paved on the other new base bed, the paving area accounts for two thirds of the surface of the new base bed, and the earthworm is normally bred;
(2) the sludge of the primary bed is completely withdrawn to another place to be stacked as a finished product of the treated sludge for other use, and the steps 2), 3) and 4) are repeated at the position of the primary bed.
2. The method as claimed in claim 1, wherein the biological agent is Geliwang biological agent produced by Yadu Fenghe amino acid factory in Bifen City.
3. The method for treating domestic sludge by combining microbial treatment and earthworm treatment according to claim 1, wherein the height of the bed is 10 cm-15 cm, the width is 1.2 m-1.5 m, the length is less than or equal to 100 m, a working channel with the width of at least 3m is reserved in the shed along the length direction of the bed, and the working channel is arranged along one side or two sides of the bed.
4. The method for treating domestic sludge by combining microbial treatment and earthworm treatment according to claim 1, wherein the nutrient solution is prepared from 100kg of water, 2kg to 3kg of urea, 3g to 5g of saccharin, 3mL to 5mL of pineapple essence and 30mL to 50mL of acetin.
5. The method for treating domestic sludge by combining microbial treatment and earthworm treatment according to claim 1, wherein the attractant is clove oil produced by a Wuhan city east lake bear Guchuan fish bait flavor factory.
6. The method for treating domestic sludge by combining microbial treatment and earthworm treatment according to claim 1, wherein the microbial composite strain is an Ames microbial strain produced by Ames biotechnology Limited in Beijing century, and comprises actinomycetes, azotobacteria, silicate bacteria, Bacillus subtilis, Paenibacillus polymyxa, Trichoderma and microzyme, wherein the photosynthetic bacteria are independently packaged by viable bacteria in a dark place, and the composite microbial strain: the weight ratio of the sludge is 1: 100.
