An object of the present invention is to provide a vehicle which is
capable of recycling contaminated liquid in a factory or the like swiftly
and efficiently without performing incineration. In order to achieve this
object, a contaminated liquid filtration system vehicle is characterized
in comprising: vehicle driving unit comprising a driving engine and a
driving mechanism; suction unit for aspirating the contaminated liquid
within a contaminated liquid collection unit as liquid to be treated; a
filtration system constituted by a charged filter device and a charged
coalescer type oil water separator for filtration treating the aspirated
liquid to be treated; electric power supply unit for supplying a driving
power source to the filtration system; delivery unit for returning
treated liquid which has been treated in the filtration system to the
same or a different collection unit in the factory or the like; and
control unit for controlling operations of the filtration system, wherein
the charged filter device is caused to advance the filtration of impurity
particles by applying a voltage between electrodes within the charged
filter device using the driving power source supplied from the electric
power supply unit, and the charged coalescer type oil water separator is
caused to advance oil water separation by applying a voltage between
electrodes within the oil water separator using the driving power source
supplied from the electric power supply unit.
