The invention provides a device inactivating visible invertebrates in raw water through pulse electricity. The device comprises a raw water main pipeline, wherein a parallel connected inactivation bypass pipeline is arranged on the raw water main pipeline, and an electricity inactivation mechanism is arranged on the inactivation bypass pipeline; a first stainless steel grating is used for intercepting part of visible invertebrates; a second stainless steel grating is connected to the anode of a pulse power, and a third stainless steel grating is connected to the cathode of the pulse power to apply pulse electricity to the visible invertebrates for inactivation. The pulse electric field is utilized by the device, and the visible invertebrates which are longer than 1 mm in the raw water are inactivated at the front end of a water treatment process, so that the visible invertebrates can be effectively removed in the subsequent processes of concreting, depositing and filtering.
