Provided are: a dispersant which has good dispersibility and reduces electronic resistance; and a battery having excellent characteristics, which uses this dispersant and is decreased in the ionic resistance and the reaction resistance. A dispersant contains a triazine derivative represented by general formula (1), and an amine or an inorganic base (in general formula (1), Ris as defined in the description).

Dispersant, dispersant composition, dispersion composition for batteries, electrode and battery

A sludge receiving facility is provided with upper and lower structures respectively having inner spaces communicating with each other, wherein sludge tanks each having a sludge charging port are provided in the lower structure, and a partition wall configured to partition a carrying-in space of the upper structure from the inner space is provided, the sludge receiving facility including: outside air blowing means; air circulating means configured to enable the inner space and the carrying-in space to communicate with each other; first exhausting means configured to exhaust air from an upper part of the carrying-in space; second exhausting means configured to exhaust air above the sludge charging port; and third exhausting means configured to exhaust air inside the sludge tanks, wherein opening/closing means are respectively provided in the circulating means and the first to third exhausting means.
