The invention belongs to the technical field of environmental engineering and particularly relates to a method for copper-containing electroplating wastewater treatment and copper recovery by a sulfide precipitation method. The method includes: adjusting a pH value of copper-containing electroplating wastewater to 1.5-3.0, then adding sulfide solution, stirring for reaction, and performing solid-liquid separation after reaction is finished to obtain pretreated wastewater and copper sulfide precipitate; adding part of solid sulfides into the pretreated wastewater, and performing primary stirring reaction; adding residual solid sulfides, and performing secondary stirring reaction; adding a flocculating agent after secondary stirring reaction is finished, and stirring for reaction; adjustingsystem pH to 7.0-8.0 after reaction, and performing solid-liquid separation to obtain mixed heavy metal sulfides and supernatant reaching the emission standard. By the sulfides, efficient separation and recovery of copper from the copper-containing electroplating wastewater is realized while harmlessness of the electroplating wastewater is realized as well, and simplicity in operation, stability in operation, low cost, high recycling level and freeness of secondary pollution are achieved.
