Multi-waste liquid diversion method and electroplating production system

Abstract

The invention relates to a multi-waste-liquid splitting device and an electroplating production system. The multi-waste-liquid splitting device comprises a liquid storage tank, a first waste liquid detection assembly and a second waste liquid detection assembly, wherein one end of the liquid storage tank is in communication with a liquid inlet pipe, and the other end of the liquid storage tank isin communication with an acid liquid drainage pipe, a maintenance liquid drainage pipe and a cleaning liquid drainage pipe; the first waste liquid detection assembly comprises a first controller, a first electric control valve and a first detection sensor, the first electric control valve is in communication with the acid liquid drainage pipe and the first detection sensor is arranged inside the liquid storage tank; and the second waste liquid detection assembly comprises a second controller, a second electric control valve and a second detection sensor, the second electric control valve is incommunication with the maintenance liquid drainage pipe and the second detection sensor is arranged inside the liquid storage tank, wherein each of the first detection sensor and the second detectionsensor is provided with a PH value detection module and an ORP detection module. According to the multi-waste-liquid splitting device, automatic splitting of waste liquid with different properties can be automatically realized according to the measured PH value and the measured ORP value, the splitting precision and the splitting efficiency are high, the whole process does not need manual participation, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of waste liquid diversion treatment, in particular to a multi-waste liquid diversion method and an electroplating production system. Background technique [0002] As the environmental protection requirements put forward by the national environmental protection department are getting higher and higher, the industrial emission standards are also developing in the direction of higher requirements, clearer emission destinations, and more scientific management levels. For example, in the process of PCB board production, it is usually necessary to use an electroplating cylinder to perform electroplating processing on the board. In the whole electroplating production, after electroplating nickel, the electroplating tank will produce nickel waste liquid; in order to avoid bacterial reproduction, it is necessary to use strong oxidizing nitric acid to squeeze the tank, which will produce nitric acid waste liquid; fina...

Problems solved by technology

[0003] The current treatment method still stays in the manual operation mode of the valve, which has the problems of high labor intensity, poor diversion accuracy and incomplete liquid separation, which is prone to mixed liquid and affects the subsequent wastewater treatment efficiency.
