A riding lawn mower includes a seat, a chassis configured to support the seat, a cutting assembly mounted to the chassis, a walking assembly configured to drive the riding lawn mower to walk on a plane, and a steering wheel assembly. The steering wheel assembly includes a steering wheel operable by the user and a connecting rod configured to connect the steering wheel and the chassis. The steering wheel assembly further includes a pivot assembly that rotatably connects the connecting rod and the chassis, and the pivot assembly enables the steering wheel assembly to switch between a working position and a storage position. A distance between the steering wheel and the plane when the steering wheel assembly is in the storage position is smaller than a distance between the steering wheel and the plane when the steering wheel assembly is in the working position.

It discloses an application of a fermentation broth ofin the removal of nitrogen in constructed wetlands. The fermentation broth ofis prepared by the following method: collecting, draining off and grinding the, then, placing the grindedinto a fermentation tank, mixing them with domesticated fermented sludge, and then adding water and fermenting the mixed liquor at a constant temperature, removing the residue of the, and obtaining the prepared fermentation broth of. The present invention also discloses an application of the fermentation broth ofin the removal of nitrogen in constructed wetlands.
