Description

Technical Field

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

[0002] 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. Circuit boards contain a large number of metal components. During the process of chemical copper deposition and etching, copper-containing wastewater is generated by complexation, chelation and other methods. The wastewater contains a large amount of copper elements and needs to be decolorized and precipitated. The commonly used decolorization method usually uses the sulfidation method, using the S2- in the sulfide and the Cu2+ in the copper ammonia complex ion to generate CuS precipitation, so that copper is separated from the wastewater, and the excess S2- is removed by iron salts to generate FeS.

[0003] After the existing circuit board is subjected to wastewater decolorization treatment and chemicals are added to treat the metal in the wastewater, CuS precipitates and FeS precipitates will be attached to the reaction pool. If the CuS precipitates and FeS precipitates are not collected and removed, the working efficiency of the wastewater treatment will be affected. The collected CuS precipitates and FeS precipitates can be subjected to subsequent purification treatment after treatment. The iron salt added during the decomposition process is usually solid or powdery, which is difficult to mix with the wastewater, and the decolorization efficiency is low. Therefore, this patent proposes a circuit board wastewater decolorization device to solve such problems. Utility Model Content
