摘　　要：采用超高温(70℃)两相厌氧反应器处理玉米加工过程中产生的黄浆废水,考察了进水COD浓度和负荷、C/N值等对系统除污效能的影响。结果表明:工艺运行稳定,在低C/N值和低负荷条件下,产酸反应器对COD的去除率为 47. 5%,酸化率(VFA/COD)为 52. 7%,蛋白质水解率为 95%,产甲烷反应器对COD的去除率为 91. 8%,两相总去除率为 97. 0%;在中高进水COD浓度和低C/N值条件下,产酸反应器对COD的去除率为 57. 6%,产甲烷反应器的为 88. 1%,两相总去除率为 93. 8%。当C/N值大幅度增加时产酸反应器对COD的去除率明显降低,而产甲烷反应器则有所增加,使总去除率仍可达 90%以上。Two-phase anaerobic reactor was used to treat wastewater produced from corn processing with ultra-high temperature (70 ℃), and the effect of influent COD concentration and loading, and C/N ratio on the pollution removal efficiency was investigated. The result shows a steady operation. Under low C/N and low loading, COD removal rate is 47.5%, acidification ratio (VFA/COD) is 52.7%, and protein hydrolysis rate is 95% in acidogenic reactor; and COD removal rate is 91.8% in methanogenic reactor; total removal rate in the two-phase reactor is 97.0%. Under the conditions of medium-high COD concentration and low C/N ratio in influent, COD removal rate is 57.6% in acidogenic reactor and (88.1)% in methanogenic reactor, with total removal rate of 93.8% in the two-phase reactor. When C/N ratio is increased greatly, COD removal rate is significantly reduced in acidogenic reactor and is somewhat increased in methanogenic reactor; however, total removal rate may come up to over 90%.
