A kind of electroplating wastewater filtration device and process based on modified petroleum resin

Abstract

The invention relates to the technical field of wastewater treatment, and discloses a modified petroleum resin-based electroplating wastewater filtering device and process, comprising a sedimentation component, a separation component is arranged inside the sedimentation component, a filter component is arranged at the front end of the sedimentation component, a filter press component is arranged at the bottom end of the sedimentation component, the sedimentation component comprises a sedimentation tank, side grooves are arranged on both side walls of the sedimentation tank, both ends of the inner wall of the side grooves are arranged with intermediate grooves, both ends of the side grooves are arranged with end grooves, adjacent grooves are arranged at positions adjacent to the end grooves, the number of adjacent grooves is two and they are symmetrically distributed on both sides of the sedimentation tank, a top mounting plate is symmetrically installed at the upper end of the sedimentation tank, uniformly distributed injection tubes are fixedly installed on the top mounting plate, a drainage tube is fixedly installed on the rear end surface of the sedimentation tank, and the pipe mouth of the drainage tube points to the internal space of the sedimentation tank. The device can completely isolate the bottom sediment inside the sedimentation tank from the upper clear liquid, so as to facilitate the subsequent separation operation.
