Based on both of the remov al perf orm ance and the o perating costs, optim al reaction co ndition w as pro posed. Operating at H O 2 2 2+ concentr at ion 220 mg/ L, Fe concentration 180 mg / L , PA M concentr at ion 45 mg/ L , r eaction t im e 05h and pH = 7 , about 445% of COD w as r emoved and chrom a reached 35. In addition , throug h analyzing of the ch ang es of molecular w eight distribution and const itute of organic compounds in effluent , the pollutant transform ation rule w as put f orw ard . T he result show s th at t he effluent t reated by Fenton ox idation cooperated w ith coagulation can reach the w astew ater secondary disch ar ge standard , and the operation cost s are acceptable.
