Abstract
The disclosure discloses an online resourceful treatment method of electroless copper plating waste solution. According to the disclosure, a copper catalyst is adopted to perform autocatalytic reaction on electroless copper plating waste solution in an autocatalytic reactor, copper simple substances are reduced from copper ions in the waste solution and recycled, the treated waste solution enters into a three-dimensional electrolyzer and a membrane filtration plant for further purification, the finally treated electroless copper plating waste solution meets water quality discharge standard, and the recovery rate of the copper simple substances can reach up to above 95%.
