一种新型中小企业制革综合废水处理法研究

Research on a new type synthetically tan wastewater treatment of midtype and minitype company

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p（SS）p（BOD5）．p（C0DCr）p（TCr）p（S^2-）．色度分别为2120m·L^-1,648mg·L^-1．124mg·L^-1,962mg·L^-1．1138mg·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 meau 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 ehrominance separately in the interest of 2120mg · L^-1. 648mg · L^-1, 1240mg · L^-1 96.2mg · L^-1 113.8mg · L^-1,840-fold when inakes appear above water 82mg ·L ^-1, 32mg·L ^-1, 78mg ·L^-1. 06mg ·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.
