Abstract

The invention relates to the technical field of wastewater treatment, in particular to an industrial park nickel-containing wastewater treatment system, which comprises a pH adjusting box, the inlet end of the pH adjusting box is fixedly provided with a liquid inlet pipe, and the outlet end of the pH adjusting box is connected with a quantitative discharge mechanism through a guide pipe; a quantitative discharging mechanism comprises a barrel, a guide-in pipe and a guide-out pipe are fixedly installed at the inlet end and the outlet end of the barrel respectively, a first one-way valve is fixedly installed at the inlet end of the guide-in pipe, a second one-way valve is fixedly installed at the outlet end of the guide-out pipe, a piston is slidably installed in the barrel, a push-pull rod is fixedly installed at the top of the piston, a guide seat is mounted at the top of the barrel, a mounting box is fixedly mounted at the top of the pH adjusting box, a driving motor is fixedly mounted at the top of the mounting box, and an output shaft of the driving motor is fixedly connected with a spiral stirring shaft. According to the method, the nickel-containing wastewater with the adjusted pH is quantitatively discharged, and the recovery efficiency of metal nickel in an electrolytic cell is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a nickel-containing wastewater treatment system in an industrial park. Background technique [0002] Electroless nickel gold is also called immersion nickel gold, which is often called electroless nickel gold in the industry. PCB chemical nickel gold refers to a solderable surface coating process of electroless nickel plating on the bare copper surface, and then chemical immersion gold. It is both It has good contact conductivity and good assembly and welding performance. At the same time, it can also be used in conjunction with other surface coating processes. With the ever-changing development of the electronics industry, the role of the chemical nickel-gold process is becoming more and more important. The more important; in the prior art, after the electroless nickel plating solution is used for several cycles, the electroless nickel plating waste liquid will be f...
