In order to develop a high efficient and low-cost wastewater treatment process and reach the standards of reuse water quality,the paper carried out the comparative effect of CODCr by combined H2O2-AC and Fenton-AC with active corbon.The results indicate that under ambient temperature,with 200mL water sample,when pH is 3 and strength oscillation is 150 rmp,compared with H2O2-AC,Fenton-AC saves AC 200mg,time 10 h,however the removal rates of CODCr increases by 17.6%.The experiment promulgated the reaction mec...
