Abstract:
According to the characteristics of wastewater from printed circuit board(PCB)production,the quality classified pretreatment-coagulation-sedimentation-mechanical filtration process has been used for treating PCB wastewater.The running results show the effluent of PCB wastewater system can be up to the first grade of "Integrated Wastewater Discharge Standard"(GB 8978 — 1996).At the same time,the reverse osmosis equipment is used for treating the system effluent and the final effluent has met the demand of the elementary reuse water quality.
