PCB etching and stripping processes in the manufacturing process after the cleaning process that occurs in low concentrations of copper etching and stripping processes compared to the concentration of copper is low emissions. So, because of the low recovery rate of waste water treatment plant is fed with a high concentration. In this study, in the manufacture of PCB cleaning wastewater generated in the cleaning process by analyzing the chemical properties of cleaning wastewater to understand. Also, cleaning the copper contained in the wastewater are effectively recovered and are looking for a way to resource recycling. PCB etching occurs on-site cleaning wastewater generated in the primary, the first detachment Sampling cleaning wastewater TOC, conductivity, Cu were analyzed. As a result, etching and stripping wastewater cleaned when comparing cleaning wastewater containing copper was higher in etching. Also ablation etching and cleaning of waste water cleaning wastewater TOC and Conductivity is measured higher load of wastewater treatment and inhibits copper absorption was considered to be a factor. Thus, the degradation of the compounds contained in wastewater pretreatment for was to use the facility. Using the photocatalytic pretreatment facility UV/TiO2 System was selected. Gel state by hydrolysis of TiCl4 prepared and coated on the quartz tube. Four times a coating is found to have the highest efficiency was applied to study the adsorption of metal ions copper selective chelating resin was used as the adsorption. As a result, copper is far short of the expected standard of 85% of its yield was about 60%. This equipment is UV/TiO2 Pretreatment System is not operating normally in the decomposition of the compound that is expected as a result. After recovery through research to find ways to increase will have to see.
