Description

Technical Field

[0001] The utility model relates to the technical field of reaction tanks, in particular to a catalytic filtration reaction tank for electroplating wastewater. Background Art

[0002] The patent with the published authorization announcement number CN207645977U discloses a catalytic reaction filtration device for electroplating wastewater, including a reaction tank body, in which a first-stage filter chamber, a second-stage filter chamber and a third-stage filter chamber are sequentially arranged, a multi-layer activated carbon filter screen is arranged in the first-stage filter chamber, a fixed frame is detachably arranged in the second-stage filter chamber, an active filler is arranged in the fixed frame, a filter screen coated with an ultraviolet light oxidation catalyst is arranged in the third-stage filter chamber, and an ultraviolet lamp is arranged above the filter screen in the third-stage filter chamber. The wastewater is treated through the three-stage filter chamber. In the second-stage filter chamber, under the action of the catalyst, the non-degradable high-molecular organic matter in the wastewater reacts chemically with the active filler, so that it is precipitated or degraded from the solution in the form of a precipitate. Moreover, in the third-stage filter chamber, the ultraviolet light oxidation catalyst is further sterilized under the irradiation of the ultraviolet lamp, and the wastewater purification treatment effect is good.

[0003] When electroplating wastewater is catalytically filtered in a reaction tank, particulate matter in the electroplating wastewater tends to sink to the bottom after a long period of reaction. The electroplating wastewater catalytic reaction filtration device in the above-mentioned patent does not process the particulate matter that sinks to the bottom of the reaction tank, thereby affecting the catalytic filtration effect of the electroplating wastewater. When the particulate impurities in the reaction tank accumulate to a certain extent, the service life of the reaction tank is affected, and the loss is increased.
