The copper phthalocyanine wastewater is treated with physical and chemical pretreatment and A/O treatment process.The effects are studied on treatment results with pH,SO2-4,water temperature and cuprammonia complex ion separately are studied.The experiment result shows that the two stage deposition treatment processes are efficient in callback copper and reduce remnant copper ion in wastewater by eliminating cuprammonia complex ion.The treated effluent conforms to the effluent standard(GB8978-96) on A/O biochemical treatment process finally.
