查询词典 nitrified

Denitrification gradually took over methanogenesis to become the main reaction responsible for decomposition of MSW, while nitrogen gas was generated instead. Additionally, owing to long term exposure of nitrified leachate to MSW, the bacterial structure of landfill was changed.

在此过程中，反硝化逐渐代替产甲烷作用成为填埋场内垃圾降解的主要反应，产生气体以氮气为主，而非甲烷；硝化渗滤液与垃圾的长期作用也改变了填埋场的菌群结构。

We studied the infection ofthe different reactant ratios to the degree of nitration when the polystyrere was nitrified. Thena series PS-NH_2 With different concentrations of amidocyanogen were gained by reducingPS-NO_2. At last the high active acryloylthiourea were grafted on the amidocyamogens.

在聚苯乙烯的硝化过程中，研究了不同的反应物配比对硝化度的影响，并对不同硝化度的硝基聚苯乙烯进行还原反应，得到了胺基含量不同的系列胺基聚苯乙烯，最后利用聚苯乙烯上的胺基和高活性的丙烯酰基异硫氰酸酯进行加成，合成AGPS。

In comparison with typical Orbal oxidation ditch, the modified Orbal oxidation ditch illustrates more concisely and compactly with no need to construct an independent sedimentation tank, which can decrease 1/3 to 1/2 of land occupation; and the backflow of sludge and nitrified water can be hydraulically processed, which saves the energy consumption for dynamic backflow.

与典型奥贝尔工艺相比，改良型奥贝尔工艺简洁紧凑，无需建造单独的二沉池，占地可减少1/3～1/2；而且污泥和硝化液回流都能依靠水力回流，节省了动力回流的能量投入。

The TiSi2 reactants in the green compacts with 50% porosity were fully nitrified and the final products were composed of Si3N4, SiC and TiN.

压坯孔隙率为50％时，反应物TiSi2氮化充分，最终产物为Si3N4-SiC-TiN。

A novel polymeric organic thermal stabilizer for PVC was designed and synthesized by acryloylthiourea grafting on polystyrene which was nitrified by HNO3 and then reducted by Sn powder to amine.

以经部分硝化和还原的低分子量聚苯乙烯为母链，利用其胺基和丙烯酰基异硫氰酸酯加成，合成了一种新型有机高分子型PVC 热稳定剂——丙烯酰基硫脲接枝聚苯乙烯，其结构经IR和元素分析表征。

The results indicate that ① the reactor with sulfur particle size of 2.8-5.6 mm can effectively remove nitrate from nitrified leachate up to a concentration of 400 mg/L NO - 3 N at a hydraulic retention time of 5.71h;② the minimum hydraulic retention time necessary for complete denitrification depends on sulfur particle size and influent nitrate concentration;③the maximum volume...

结果表明，当HRT为5.71h，硫磺粒径为2.8－5.6mm时，最高处理浓度（以NO－3－N计）达400mg／L。达到完全反硝化所需的最小停留时间取决于硫磺粒径及进水硝酸盐浓度。硫磺粒径为2.8－5.6mm，5.6－11.2mm，11.2－16mm时，NO－3－N最高容积负荷分别为594，278，175.4g／（m3d）。NO－3－N最大表面负荷约为0.68g／（m2d），是自养反硝化的控制因素，与硫磺粒径无关。

The result shows that the recycling effluent upgrades significantly the removal for BOD_5,COD,SS,and NH~+_4-N,and BOD_5 removal rate meets the Monod equation;most part of NH~+_4-N is nitrified and the removal rate of NH~+_4-N is linear with the surface loading rate.Along with the nitrification,alk...

结果表明：循环出水显著提高了对BOD5、COD、SS和NH+4-N的去除率，且对BOD5的去除满足Monod方程；大部分NH+4-N的去除率与其表4-N被硝化，对NH+面负荷率呈线性关系；随着硝化反应的进行，碱度减少，pH值不断降低；循环出水可引入部分氧气，延长了污染物和附着于植物根系微生物的接触时间，提高了对污染物的去除率。
