摘　　要：采用以催化铁内电解法联合CAST法处理制革综合废水,当进水ρ(SS),ρ(BOD5),ρ(CODCr),ρ(TCr),ρ(S2-),色度分别为2120mg·L-1,648mg·L-1,1240mg·L-1,96.2mg·L-1,113.8mg·L-1,840倍时,出水82mg·L-1,32mg·L-1,78mg·L-1,0.6mg·L-1,0.3mg·L-1,8倍,出水水质稳定能够达到二级排放标准。此工艺操作简便,造价低廉,适用中小型制革企业的废水处理。Adopting the pretreatment mean with catalysis iron inner electrolysis and CAST technology giving priority to handle the synthetically tan wastewater, the SS, BOD5, CODcr, chromium invariably, S^2- and chrominance separately in the interest of 2 120mg·L^-1, 648mg·L^-1, 1 240mg·L^-1, 96.2 mg·L^-1, 113.8 mg·L^-1, 840 -fold when intakes appear above water 82mg·L^-1, 32 mg· L^-1, 78mg·L^-1, 0.6mg·L^-1, 0.3mg·L^-1, 8 -fold , and the water quality appearing above water is steadied attaining two grades to place in proper order the criterion. This technology operates portably, and cost is inexpensive, so it being applicable to the middle small scale tan plant.
