The invention discloses a copper-containing printed circuit board wastewater treatment method which specifically comprises the following steps: step 1, pumping copper-containing printed circuit boardwastewater, which contains copper complex, into a reaction kettle by using a pump, and adjusting the pH value of the wastewater, step 2, adding a complex breaking agent into the reaction kettle, carrying out complex breaking reaction on the complex breaking agent and the wastewater copper complex, and stirring for 30-40 minutes; step 3, adding an oxidizing agent into the reaction kettle, carryingout enhanced reaction on the oxidizing agent and the wastewater copper complex, and stirring for 30-40 minutes; 4, adjusting the pH value of the wastewater, adding a precipitant, carrying out precipitation reaction on the precipitant and the wastewater copper complex, and stirring for 20-30 minutes; and step 5, regulating the pH value of the wastewater, adding a flocculating agent, stirring for 5-10 minutes, precipitating and standing for 2-3 hours. The invention solves the problems of high cost and poor precipitation effect in the existing wastewater treatment method.
