The experimentation inspected the infection of hydraulic load, organic load, ammonic nitrogen load, the ratio of gas and water, the height of filling to removal efficiency of COD and ammonic nitrogen based on the self-confected water. 本试验以自配生活污水为试验用水,考察了水力负荷、进水有机负荷和氨氮负荷、气水比、填料层高度对曝气生物滤池处理COD和氨氮效果的影响。
The orthogonal tests showed: the effectiveness of the factors on COD removal and ammonic nitrogen removal are characterized as follows: hydraulic load> the ratio of gas and water> the concentration of organic matter. 正交试验的结果表明:各因素对COD去除效果和氨氮去除效果的影响大小依次为:水力负荷>气水比>进水浓度。
Zn and Mo nutrition could also increase protein and nuclear acid contents and NR activity, but decrease nitric nitrogen ( NO3-) and free ammonic acids contents ( FAA) and RNase activity in leaves. 锌钼营养还可提高叶片蛋白质、核酸含量以及硝酸还原酶(NR)活性,并降低游离氨基酸、NO3~-含量和核糖核酸酶(RNase)活性。
