摘　　要：使用曝气生物滤池处理腌制废水,研究了有机负荷、HRT、反应温度和NaCl含量对其除污效能产生的影响。结果表明,优化有机负荷为3.3 kg.m-3.d-1;进水COD分别为小于491.8和686.9、800.4、958.7、1 111 mg.L-1时,优化的HRT分别为2、4、6、9、11 h;优化反应温度为25℃;耐NaCl极限质量浓度是51.84 g.L-1。BAF was used for treatment of mustard tuber wastewater,the effect of organic loading,HRT,temperature and salt（NaCl）concentration on the impact of decontamination performance were studied.The results showed that： when the excellent organic loading was 3.3 kg·m-3·d-1,reaction temperature was25 ℃,salt limit was 51.84 g·L-1 NaCl,the influent water COD were less than 491.8、686.9、800.4、958.7、1 111 mg·L-1,respectively,while the optimal HRT were 2、4、6、9、11 h,respectively,the optimal reaction temperature was 25 ℃,the limit concentration of NaCl was 51.84 g · L-1.
