Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.

In this embodiment, referring to fig. 1-4, a purification device for metal heat treatment wastewater comprises a purification tank 1, wherein an upper half area of the inner side of the purification tank 1 is designed as a purification area 2, a lower half area of the inner side of the purification tank is designed as a sedimentation area 3, a water passing plate 9 capable of lifting is arranged in the purification area 2, and the plate surface of the water passing plate 9 is divided into two layers: uniformly distributed water passing holes 14 are formed in the plate surface of the lower layer, a vertical linear bearing rod 11 is arranged in the center of the lower layer plate of the water passing plate 9, the plate of the upper layer is a movable plate, the plates of the upper layer are circumferentially arrayed by a plurality of filter plates 13, the filter plates 13 of each filter plate are rotatably arranged on the upper surface of the lower layer plate through hinge shafts, and dense sieve holes are formed in the filter plates 13 of the upper layer; the inner wall of the sedimentation zone 3 is provided with a long and straight channel 7, and a plug 4 is inserted into the channel 7. The aperture of the water passing holes 14 is larger than that of the sieve holes formed on the filter plate 13.
