水タンクが設けられている。In the present invention, the garbage collection vehicle is a vehicle such as a four-wheeled vehicle generally used by the local government cleaning office to collect the garbage generated at various places and transfer it to a garbage disposal facility such as an incinerator. In addition, this garbage truck is provided with a dirty water tank for storing dirty water separated from raw garbage during transportation of the garbage.

が好ましい。The super absorbent polymer used in the present invention is a resin that absorbs a large amount of water in water and swells to form a hydrogel, and is a hydrolyzate of a starch-acrylonitrile graft copolymer or a starch-acrylic acid graft polymer. Examples thereof include a neutralized product, a saponified product of an acrylic acid ester-vinyl acetate copolymer, a crosslinked polyvinyl alcohol modified product, a partially neutralized polyacrylic acid salt crosslinked product, and a crosslinked isobutylene-maleic anhydride copolymer. Among them, the partially neutralized polyacrylate crosslinked product is preferable from the viewpoints of the amount of sewage absorbed and the cost.

用するのが好ましい。Since the fibrous reinforcing material is used so as to wrap the super absorbent resin, it is preferable to use it as a bag, for example, a straw bag. Therefore, the mesh of the fibrous reinforcing material needs to be finer than the particle size of the superabsorbent resin so that the superabsorbent resin is surely wrapped in the reinforcing material.
Furthermore, the swollen gel is usually incinerated together with the collected dust, and it is preferable to use a flammable fibrous reinforcing material.
