Abstract

The present invention relates to a printing plate etching waste liquid treatment system and a method. The printing plate etching waste liquid treatment system comprises a liquid storage tank, a first electrolysis buffer tank, an electrolysis tank, an ion membrane electrolysis tank, a cooling tank, a filtration pool and a second electrolysis buffer tank. After the system is connected with an etching line, copper recovery is achieved through sequential complexation and electrolysis, and hydrogen chloride and sodium hydroxide are obtained during electrolysis processes of the electrolysis tank and the ion membrane electrolysis tank.

Description

technical field [0001] The invention relates to the field of printed circuit board production, in particular to a treatment system and method for printing board etching waste liquid containing copper chloride. Background technique [0002] In the production process of printed circuit boards, the recovery and regeneration of acidic copper chloride etching solution has always plagued printed circuit board enterprises. The non-renewable acidic copper chloride etching solution contains about 100 grams to 180 grams of copper per liter, only Guangdong This kind of waste etching solution produced every month in the province contains thousands of tons of copper. If this kind of metal copper can be recovered and the waste etching solution can be recycled and used, it must have very important economic benefits and environmental protection value. [0003] The traditional method of treating printed board etching waste liquid only extracts copper, and the waste liquid is discharged direc...
