  • 摘要: 为进一步提高同时产甲烷反硝化反应对畜禽粪水化学需氧量（COD）和氮的去除效率，应用畜禽粪水于接种颗粒污泥的厌氧混合式反应器，进行不同COD与亚硝态氮浓度比值（COD/NO2--N）对同时产甲烷反硝化反应的影响研究。通过实时监测反应器内COD、凯氏氮（TKN）、辅酶F420、β-葡萄糖苷酶、产气率、pH和氧化还原电位（ORP）等指标得出，COD/NO2--N为30/1、40/1时，COD去除率、辅酶F420和β-葡萄糖苷酶含量与空白无亚硝态氮的变化规律一致，亚硝态氮几乎未对糖类水解菌及产甲烷菌活性产生抑制作用；而COD/NO2--N为10/1、20/1时，COD去除率、辅酶F420和β-葡萄糖苷酶含量较低，糖类水解菌及产甲烷菌活性受到抑制。
    Abstract: To improve the technique efficiency of removing chemical oxygen demand (COD) and nitrogen of livestock wastewater in simultaneous methanogenesis and denitrification,the effects of different concentration ratio associated with COD and nitrite nitrogen were analyzed.The experiment was conducted through livestock wastewater reacting in anaerobic mixing reactor which has seeded with granular sludge.Experimental results obtained by real time monitoring.The criteria are as follows:COD,total kjeldahl nitrogen (TKN),coenzyme F420,β-glucosidase,gas production rate,pH and oxidation-reduction potential (ORP).The results show that the removal rate of COD,concentration of coenzyme F420 and β-glucosidase would be consistent with no nitrite nitrogen,when COD/NO2- N reaches to 30/1 and 40/1.It is indicated that nitrite nitrogen would have few inhibition on the activity of carbohydrate hydrolysis bacteria and methanogens.Otherwise,when COD/NO2- N equals 10/1 and 20/1,the removal rate of COD,concentration of coenzyme F420 and β-glucosidase would be low,which implies high inhibition on the activity of carbohydrate hydrolysis bacteria and methanogens.
