The activated carbon or carbon-based material adsorbs the harmful gas, and the remaining gas is discharged through the vacuum pump 72;

[0058] In the sixth step, the discharge valve 44 on the discharge pipe 43 is opened through the PLC controller 9 to discharge the fermentation product, thereby completing the treatment of the aquaculture waste.

[0059] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the protection scope of the present application.
