Copper removal treatment process for copper ammonia wastewater

The invention relates to the technical field of copper removal of copper ammonia wastewater, in particular to a copper ammonia wastewater copper removal treatment process which comprises the following steps: S1, adding acid into copper ammonia wastewater, and adjusting the pH value back, so that NH3 in a copper ammonia complex in water forms NH4 < + >, a copper ammonia complex structure is destroyed, and copper forms Cu (OH) 2 to form a precipitate; s2, discharging filter residues of the copper-containing sludge by using a filter press; s3, putting a filtrate layer left after treatment in the previous step into a sodium sulfide reaction tank with a certain concentration for treatment; s4, filter residues of the copper-containing sludge are discharged by the filter press again, and a filtrate layer is left and can be directly discharged into a clean water tank; according to the process, on the premise of ensuring that copper reaches the standard, the cost is reduced by more than 1/2 compared with that of an or
