A New Method for Treating Copper Phthalocyanine-manufacturing Wastewater
On the basis of insight into the characteristics of copper phthalocynine wastewater, a combined chemical and biochemical treatment method was suggested. A series of experiments were conducted to research the effects of cuprammonia complex ions, sulphate and pH in the wastewater as well as temperature on the removal of Cu 2+ and NH 3-N. Conditions for biological treatment (A/O) of COD and NH 3-N were also studied.
