Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a circuit board sewage physicochemical treatment device. Background Art

[0002] The names of circuit boards include: circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. However, circuit boards will generate a lot of sewage during production, so how to deal with it has become a problem that must be solved.

[0003] The patent with the publication number of CN 219860884 U discloses a sewage treatment device for circuit board production, which includes a base, a water collection tank arranged above one side of the top of the base, a support frame arranged in the middle of the top of the base, a reaction barrel mounted on the top of the support frame, and a filter tank arranged on the top of the base and located on one side of the reaction barrel. The device solves the problem that the amount of flocculant added in the existing sewage treatment equipment is difficult to control and the metal ions in the sewage cannot be completely removed through the use of the base, the water collection tank, the support frame, the reaction barrel, the filter tank, the sedimentation tank and the material control component. However, the device has the problem that the amount of flocculant added is not easy to control and the metal ions in the sewage cannot be completely removed according to the amount of circuit board sewage introduced into the reaction barrel. However, this method is to push all the flocculants from one position into the sewage for reaction, resulting in the flocculant being slowly stirred and fully mixed by a stirring rod from one area of ​​the sewage before the sewage can be treated, which reduces the sewage treatment efficiency. Therefore, a circuit board sewage physicochemical treatment device is proposed to solve the problem that the flocculant in the existing sewage treatment device is difficult to quickly mix and react with the sewage.
