Treatment of 2—3 acid production wastewater with microelectrolysis-Fenton method

An experimental study is performed on the treatment of 2—3 acid production wastewater (COD_(Cr)=(3000～4000mg)/L, and chroma=32～64 times) with the microelectrolysis-Fenton method. The condition, effect, and results of the microelectrolysis reaction and Fenton reaction are discussed respectively, and some conclusions are drawn: the COD_(Cr) concentration in the effluent of the microelectrolysis reaction, after 4～5 hours’ Fenton reaction and 15～20 minutes’ coagulated sedimentation under the alkalescence condition, is about 120～140mg/L, and the COD_(Cr) removal ratio can reach 95% or above.
