Description

technical field

[0001] The invention belongs to the technical field of solid waste treatment, in particular to a microbial solid waste treatment system. Background technique

[0002] At present, there are few microbial solid waste treatment devices in China that are suitable for waste treatment experimental devices in lunar base missions. In the field of microbial solid waste treatment, simple experimental devices are often used, which have the following disadvantages: a. cannot compensate for heat loss. During the treatment process, solid fermentation produces a large amount of heat and heat loss is serious, which is not conducive to the survival of high-temperature microorganisms, and Cannot meet the harmless standard; b. The airtightness of the device is not good, which will lead to inaccurate data of gas production and gas supply measured in the experiment, and even cause the experiment to fail. c. The stirring device produces a dead angle and the stirring is uneven. d...
