Abstract

Disclosed are printed circuit board high-concentration organic wastewater and an acidic wastewater treating process. The acidic wastewater treating process mainly includes a plurality of steps, namely, acidifying and filter-pressing, iron-carbon micro-electrolysis, Fenton oxidation and flocculent settling, SBR bio-treatment and the like. By the process, organic matters in water can be removed efficiently and thoroughly, and the water is ensured to be capable of reaching the standard and discharged after being mixed with other wastewater through a comprehensive wastewater treating system.

Description

technical field

[0001] The invention relates to the field of waste water treatment, in particular to a process for treating high-concentration organic waste liquid and acid waste liquid of printed circuit boards. Background technique

[0002] The output value of the global printed circuit board industry accounts for more than a quarter of the total output value of the electronic component industry, and it is the industry with the largest proportion among various electronic component sub-sectors, with an industry scale of 55 billion US dollars. At the same time, due to its unique position in the electronic basic industry, it has become the most active industry in the contemporary electronic component industry.

[0003] The circuit board industry will produce a large amount of high-concentration organic waste liquid during the production process, mainly including the developing, film-removing waste liquid in the line process (dry film, wet film and green oil), and the waste wa...
