Embodiment 1
[0045] A method for treating sewage sludge, comprising the following steps:
[0046] Step 1. Transport the sludge from the sewage plant into the production shed, and the loader randomly spreads it on the flat ground of the production shed with a thickness of 15cm; according to the volume ratio of deodorant and water is 1:150, the After the deodorant is diluted, the deodorant dilution is obtained for subsequent use; use sterile water, and the EM bacterial stock solution is diluted according to the volume ratio of the EM bacterial stock solution and water as 1:200 to obtain the EM bacterial dilution A for subsequent use ; Using sterile water, according to the volume ratio of the EM bacteria stock solution and water as 1:100, dilute the EM bacteria stock solution to obtain the EM bacteria dilution B, for subsequent use;
[0047] Step 2, use the rotary tillage sprayer to carry out rotary tillage to the flattened sludge and then spray the deodorant dilution, and carry out 5 rotary ...
Embodiment 2
[0054] A method for treating sewage sludge, comprising the following steps:
[0055] Step 1. Transport the sludge into the production shed, and the loader randomly spreads it on the flat ground of the production shed with a thickness of 18cm; according to the volume ratio of deodorant and water as 1:150, the deodorizing After the deodorant is diluted, the deodorant dilution is obtained for subsequent use; using sterile water, the EM bacterium stock solution is diluted according to the volume ratio of the EM bacterium stock solution and water to 1:200, and the EM bacterium dilution A is obtained for subsequent use; Sterile water, according to the volume ratio of EM bacteria stock solution and water is 1:100, dilute the EM bacteria stock solution to obtain EM bacteria dilution B, set aside;
[0056] Step 2, use the rotary tillage sprayer to carry out rotary tillage to the flattened sludge and then spray the deodorant dilution for 5 times of rotary tillage spraying; after 2.5 hou...
Embodiment 3
[0062] A method for treating sewage sludge, comprising the following steps:
[0063] Step 1. Transport the sludge into the production shed, and the loader randomly spreads it on the flat ground of the production shed with a thickness of 20cm; according to the volume ratio of deodorant and water as 1:150, the deodorant After the deodorant is diluted, the deodorant dilution is obtained for subsequent use; using sterile water, the EM bacterium stock solution is diluted according to the volume ratio of the EM bacterium stock solution and water to 1:200, and the EM bacterium dilution A is obtained for subsequent use; Sterile water, according to the volume ratio of EM bacteria stock solution and water is 1:100, dilute the EM bacteria stock solution to obtain EM bacteria dilution B, set aside;
[0064] Step 2. Rotate the flattened sludge with a rotary tillage sprayer and then spray the deodorant dilution for 5-6 times of rotary tillage spraying; after 2-3 hours, use the rotary tillag...
