Embodiment 1
[0032] The method for energy-saving and environment-friendly treatment of urban sludge in the present invention is as follows: urban sludge with a weight ratio of 80% and a moisture content of 80% and cassava distiller's grains with a weight ratio of 20% and a moisture content of 10% are mixed to form a moisture content of 66%. The sludge fermentation material is then placed on a set of dynamic three-dimensional fermentation equipment consisting of 5 groups in the horizontal direction, 12 layers in the vertical direction, and a conveyor belt width of 4m for dynamic aerobic fermentation 12 Days, converted into decomposed and dry chemical materials with a moisture content of 42%, and then directly used as organic fertilizers; during the fermentation process, microorganisms were used to inoculate naturally; the layer thickness of the sludge fermentation materials laid on the belt conveyor belt was 350mm. Its processing steps are as follows:
[0033](1) Put the municipal sludge an...
Embodiment 2
[0038] The method for energy-saving and environment-friendly treatment of municipal sludge of the present invention is as follows: be 75% by weight ratio, the municipal sludge that moisture content is 80%, bagasse that is 10% by weight ratio, 10% moisture content and 15% by weight ratio , cassava starch slag with a moisture content of 10% is mixed into a sludge fermentation material with a moisture content of 62.5%, and then placed in a set of belt conveyors consisting of 10 groups in the horizontal direction, 12 layers in the vertical direction, and a conveyor belt width of 4m. Dynamic aerobic fermentation is carried out for 12 days on the dynamic three-dimensional fermentation equipment formed by the machine, and it is converted into decomposed dry chemical material with a moisture content of 35% and used as an organic raw material for the production and processing of commercial organic fertilizers; during the fermentation process, microorganisms are used for natural inoculati...
Embodiment 3
[0044] The method for energy-saving and environment-friendly treatment of municipal sludge of the present invention is: be that 80% by weight ratio, the municipal sludge that moisture content is 80%, be that 10% by weight ratio, be the bagasse of 10% moisture content and be 10% by weight ratio, The bran with a moisture content of 10% is blended into a sludge fermentation material with a moisture content of 66%, and then placed on a set of belt conveyors consisting of 5 groups in the horizontal direction, 12 layers in the vertical direction, and a conveyor belt width of 3m. Dynamic aerobic fermentation is carried out on the dynamic three-dimensional fermentation equipment formed for 12 days, and it is converted into decomposed dry material with a moisture content of 40% and then used as biomass fuel for incineration; during the fermentation process, microorganisms are used to inoculate naturally; the sludge fermentation material is in the belt type The thickness of the material ...
