The invention relates to wastewater processing technology, and especially relates to a wastewater processing technology and an apparatus capable of synchronously removing phosphates and copper ions in water. The invention provides the wastewater processing technology capable of synchronously removing phosphates and copper ions in water, ferrous sulphate is used as a coagulant and added into wastewater for coagulating sedimentation. The invention also provides the wastewater processing apparatus capable of synchronously removing phosphates and copper ions in water. The beneficial effects comprise that by adding ferrous sulphate into wastewater as the coagulant and because ferrous sulphate is low in price, the cost is relatively low, the operation is simple and the removing efficiency is relatively high; waste is used to treat waste, and metal ion catalysts originally in wastewater is utilized for effectively oxidizing ferrous sulphate and further for removing phosphates; and copper is synchronously removed in a co-precipitation manner after metal Cu is utilized to catalyze ferrous oxidation.
