Circuit board wastewater treatment equipment and treatment method thereof

Abstract

The invention belongs to the field of wastewater treatment, and particularly relates to circuit board wastewater treatment equipment and a treatment method thereof.The circuit board wastewater treatment equipment comprises a treatment barrel, a filtering and mixing component is arranged at the upper end in the treatment barrel, a first motor is fixedly arranged at the lower end in the treatment barrel, and a linkage column is fixedly arranged at the upper end of the first motor and rotationally connected in the treatment barrel; a rotating cylinder is fixedly arranged on the outer circumferential surface of the linkage column, two filtering plates are fixedly arranged in the rotating cylinder on the two sides of the linkage column, and a filtering cavity is formed in the rotating cylinder below the two filtering plates. According to the invention, circuit board wastewater can be subjected to inclined circulating filtration, so that the filter plate can be prevented from being blocked and impurities in the circuit board wastewater can be quickly removed; the circuit board wastewater is subjected to a chemical reaction, solid and liquid are separated through extrusion and filtration, respective treatment reactions are facilitated, and a copper product is obtained through an electrolytic reaction.

Description

technical field [0001] The invention belongs to the field of waste water treatment, in particular to a circuit board waste water treatment equipment and a treatment method thereof. Background technique [0002] In the process of circuit board production, cleaning is an important process in the assembly of printed circuit boards, which will produce a large amount of grinding wastewater, general cleaning wastewater, organic wastewater, comprehensive wastewater, nickel-containing wastewater, silver-containing wastewater, cyanide-containing wastewater, and film removal and development. Wastewater, etc., the wastewater cannot be discharged directly, and it needs to be treated to meet the discharge requirements. However, the traditional wastewater treatment process is complicated, the treatment cost is high, the sludge generated is expensive, and the copper resources in the wastewater cannot be recovered, resulting in Waste of resources. The current circuit board wastewater treat...

Problems solved by technology

[0002] In the production process of circuit boards, cleaning is an important process in the assembly of printed circuit boards, which will produce a large amount of grinding wastewater, general cleaning wastewater, organic wastewater, comprehensive wastewater, nickel-containing wastewater, silver-containing wastewater, cyanide-containing wastewater, film removal and development Wastewater, etc., the wastewater cannot be discharged directly, and it needs to be treated to meet the discharge requirements. However, the traditional wastewater treatment process is complicated, the treatment cost is high, and the sludge generated is expensive to treat, and the copper resources in the wastewater cannot be recovered, resulting in waste of resources

The current circuit board wastewater treatment equipment has the problem that the filter is easy to block, resulting in insufficient filtration and affecting the sewage treatment effect.
