Embodiment 1

[0030] The invention relates to an application of plant biomass resources in constructed wetlands, which utilizes plant biomass resources in constructed wetlands as raw materials to produce fuel.

[0031] The invention can use artificial wetland plant biomass resources as raw materials to prepare solid molding fuel.

[0032] When producing solid briquettes, the constructed wetland plant biomass resources are cut, dried, and then compressed into blocks or granules to form solid briquettes.

[0033] For example, plant biomass resources in constructed wetlands are cut to about 6-10 cm, dried to a moisture content of less than 15%, and then compressed into blocks or granules by solid molding equipment as solid molding fuel.

Embodiment 2

[0035] The invention relates to an application of plant biomass resources in constructed wetlands, which utilizes plant biomass resources in constructed wetlands as raw materials to produce fuel.

[0036] The invention can use artificial wetland plant biomass resources as raw materials to prepare biogas fuel.

[0037] For example, plant biomass resources in constructed wetlands are cut to 6-10 cm, and directly placed in an anaerobic fermentation device for fermentation to produce biogas fuel.

Embodiment 3

[0039] The invention relates to an application of plant biomass resources in constructed wetlands, which utilizes plant biomass resources in constructed wetlands as raw materials to produce fuel.

[0040] The invention can use artificial wetland plant biomass resources as raw materials to prepare ethanol fuel.

[0041] The ethanol fuel is produced by natural drying of plant biomass resources in artificial wetlands until the moisture content is less than 10%, crushing through a 20-80 mesh sieve, and then pretreatment, enzymatic hydrolysis and fermentation to produce ethanol fuel.

[0042] The pretreatment is to put the raw material into a NaOH solution with a concentration of 1%, the mass ratio of the raw material to the NaOH solution is 1:10, treat it at room temperature and 180 rpm for 12 hours, and then add a concentration of 31% H 2 o 2 After 12 hours of treatment, after solid-liquid separation, the solid residue was collected and washed with water to adjust the pH to 4.8...
