The invention relates to a batch filter device and a batch filter method of heavy metal-containing waste water. The filter device comprises an outside frame, a suction cavity is formed in the frame in a surrounding manner; the inner side of the suction cavity is communicated with at least one suction connector; the other end of any of the suction connectors is communicated with the filter device for filtering a water sample; multiple suction holes are formed in the outer side of the suction cavity and any one of the suction holes is plugged by a hole plug; the outside frame is provided with a top cover. According to the batch filter device, multiple to-be-tested water samples can be filtered or sucked into sample tubes at one time; the operation is simple; the clean is convenient and the pollution to heavy metal in water samples can be avoided.
