毛皮染色废水是一种高盐度、难降解、高污染的工业废水，普通生化法对这一类废水的处理效果很不理想。从处理偶氮染料模拟废水的厌氧污泥中，分离纯化出6株偶氮染料高效降解菌，进行了复合细菌菌剂的制备，并通过直投法和菌剂强化污泥法进行了实际毛皮染色废水的处理，同时优化各项运行参数，测定出了水CODCr及色度评价处理效果。结果表明，在菌液投加量为5％（V／V）、0 h一次投加、外加营养物C／N为5∶1、进水pH为5等条件下，其对废水的C O D去除率可以达90％以上。对直投法处理液中的微生物进行分离培养，其结果显示主要菌种仍为复合菌剂组成菌株，这说明所制备复合菌剂在处理毛皮染色污水时具备稳定性。

Fur dyeing wastewater is a highly recalcitrant industrial pollutant resource which makes traditional biochemical treatment somehow inefficient .We prepared compound bacte‐rial agent with 6 high efficient azo dye degrading bacterial strains and use the agent for actual fur dyeing wastewater treatment through direct addition method and bioaugmentation meth‐od ,respectively .We also optimized the operation parameters ,measured CODCr and chromatic‐ity of the effluent to evaluate treatment effect .Results showed that by one batch addition with amount of 5% (V/V) at 0 h ,C/N of 5∶1 ,initial pH value of 5 ,the COD removal rate could be more than 90% .Molecular identification of the isolated strains from the treated fluid confirmed the biological stability of the compound bacteria agent in the treatment of fur dye‐ing w astew ater .
