通过实验室模拟实验研究渗滤液中污染物在地下环境中迁移转化作用,实验结果表明,垃圾渗滤液在地下出现了4个顺序氧化还原带,分别为产甲烷带、Fe(III)还原带、NO-3还原带和氧还原带,微生物在每个带利用的最终电子受体是不同的。

A soil column filled with sandy soil was constructed to investigate biogeochemical process of leachate pollutants degradation and redox zones in subsurface environment,and variation of Fe~3+,Fe~2+,oxidation capacity (OXC) and reduction capacity(RDC) of fresh and contaminated soil were analyzed.

结果表明,垃圾渗滤液污染羽中出现了4个顺序氧化还原带,微生物在每个带所利用的最终电子受体是不同的,分别为CO2、Fe3+、NO-3和O2,相应地依次称为产甲烷带、铁还原带、NO-3还原带和氧还原带;各带的标志性物质HCO-3、Fe2+、NO-2和DO的最高值分别为10 353 mg/L、13。

As pollutants are migrated in the unsaturated zone, biologic oxidation zone is produced in the upper part and biologic reduction zone is developed in the underside.

污染物在包气带中迁移时,会在表层形成生物氧化带,在下 部形成生物还原带。

Effects of reducing agents on NO reduction over Ag/Al_2O_3 catalyst;

还原剂对Ag/Al_2O_3催化剂上NO还原的影响

The results showed that NO reduction and NO oxidation.

结果表明:NO还原和氧化在其脱除过程中同时共存,当NO,N2,O2,H2O和CO2的体积浓度分别为200×10-6,80%,5%,6%和9%时,NO氧化所占的比例比NO还原的大很多;脉冲频率增大导致NO还原率和氧化率均增大;H2O浓度增大导致HNO3浓度增大,表明NO氧化所占的比例随H2O浓度增大而增大。

Combustion experiments on Shenmu bituminous coal and Geliping blind coal were carried out in a high-temperature horizontal twin-tube quartz stove,and NO volume fraction was measured in real-time during the combustion to investigate the effect of magnesium acetate on NO reduction.
