| 摘 要： | 采用人工合成废水对IC反应器在微氧和厌氧条件下去除COD的效果、沼气产量、出水VFA、颗粒污泥粒径分布及颗粒污泥浓度等进行对比试验研究.结果表明:在进水COD分别为1 000、2 000、2 600、3 300、4 000 mg/L时,与厌氧相比,微氧时(溶解氧控制在0.5～1.0 mg/L)对COD的去除率分别增长了4.0%、4.0%、2.6%、1.5%、0.9%,沼气产量分别增长了160.0%、137.0%、78.0%、90.5%、50.9%;两种条件下的出水VFA均在200 mg/L以下,但与厌氧相比,微氧的出水VFA值更低、波动更小、变化更平稳;微氧时颗粒污泥的MLSS减少了3.6%,而MLVSS/MLSS值增长了0.6%,表明颗粒污泥的活性增强.

| Abstract: | Artificially synthetic wastewater was treated by the IC reactor under anaerobic and micro-aerobic conditions.COD removal,biogas production,effluent VFA,size distribution of granular sludge and sludge concentration under the two reaction conditions were compared.The results show that when the influent COD concentrations are 1 000 mg/L,2 000 mg/L,2 600 mg/L,3 300 mg/L and 4 000 mg/L respectively,the COD removal rates and biogas production under micro-aerobic condition(dissolved oxygen of 0.5 to 1.0 mg/L) are ... |
