[0001] The utility model relates to the technical field of electroplating wastewater treatment equipment, in particular to an adsorption and filtering device for electroplating wastewater. Background Art

[0002] At present, the treatment of wastewater or waste liquid discharged from electroplating production. The wastewater and waste liquid discharged from electroplating factories contain a large amount of metal ions such as chromium, tin, nickel, cyanide, acid, alkali, and generally contain organic additives. Some metal ions exist in the form of simple cations, some exist in the form of acid anions, and some exist in the form of complex complex ions. Neutralization precipitation method, neutralization coagulation precipitation method, oxidation method, reduction method, barium salt method, ferrite method, adsorption method and other methods are commonly used in the treatment of electroplating wastewater.

[0003] After searching, a Chinese patent with announcement number CN 219823755 U discloses a high-efficiency adsorption device for electroplating wastewater treatment, comprising an upper box and a lower box, a raised opening cavity is provided on one side of the lower box, the upper box is arranged above the opening cavity, a water inlet is provided on the top of the upper box, a filter screen partition is provided inside the upper box, a reciprocating impurity removal block is provided on the filter screen partition, and the impurity removal block is connected to a driving mechanism through a long rod; a fixed plate is provided on the side of the lower box away from the upper box extending downward from the top of the inner cavity, a water outlet gap is reserved between the lower end of the fixed plate and the bottom of the cavity, an activated carbon adsorption layer is provided in the lower box, one side of the activated carbon adsorption layer is connected with the fixed plate, a water outlet is provided at the lower part of one end of the lower box away from the upper box, and a visual window is provided on the lower box between the fixed plate and the water outlet for easy observation, the long rod is driven to reciprocate left and right by a connecting rod, and the impurity removal block follows the reciprocating left and right motion, and the impurity on the surface of the filter screen partition is continuously pushed to both sides to ensure that the surface of the filter screen partition is always kept unobstructed.

[0004] The inventor has found that in the above technology, a series of structures such as a debris removal block, a long rod, a connecting rod, a turntable, and a driven wheel are set up to push the debris on the filter to the edge to avoid affecting the normal flow rate of the water flow. However, as the working time increases, more and more debris will accumulate on the filter, which is not convenient for cleaning the debris on the filter. Secondly, using a debris removal block to push the debris will cause smaller foreign matter to be stuck in the filter holes, which will actually affect the water flow rate and does not effectively solve the problem caused by the generation of debris during filtration. Therefore, the utility model proposes an adsorption filtration device for electroplating wastewater. Utility Model Content
