- Effect of Additive on COD N and P Remove from Wastewater 添加剂对废水中COD、N和P去除的影响
- N and P removal 脱氮除磷
- The reduction speed is increasing along with the concentration of N and P in water, whereas the removal rate of N and P is descending. 氮磷浓度的降低速率随水体中氮磷浓度的升高而升高，而对氮磷的去除率随水体中氮磷浓度的升高而降低。
- Besides, Vallisneria spiralis L. and Canna had no significant difference in removal efficiencies of N and P in both lab experiment and field test. 在实验与现场条件，美人蕉与苦草对总氮和总磷的去除率之间没有显著差异。
- However fertilizer regimes for oil palm in Thailand have tended to emphasize N and P more than K. 然而，泰国现在油棕榈的施肥状况，比起钾来，更偏向重视氮和磷。
- The volumes of N and P in EPQ were obviously related with SCL-90 total score multiple factors. 强迫症患者EPQ中的N量表和P量表与SCL - 90总分及多项因子分明显相关。
- Many studies on effect of N and P to algae of in Dianchi lake influenced by N and P hasbeen reported. 有关氮、磷对滇池藻类生长的影响研究已有大量的报道。
- These values were compared with the N and P concentration in sediments and macrophyte biomass in order to assess nutrient availability, fate and storage capacity. 这些数值被用来与沉淀物和大型动植物中的氮磷浓度相比较，由此得出营养物质的有效性，去向和储存量。
- Acorus calamus was more efficient for accumulating N and P, while Iris tectorum had more N and P per plant as a result of its much higher biomass. 菖蒲各器官氮、磷含量均高于鸢尾,但是单株鸢尾对氮、磷的积累量比菖蒲大。
- In addition, applying nitrification inhibitors could increase vitamin C and soluble sugar contents in pakchoi, and promote N and P uptakes by pakchoi. 另外，3种硝化抑制剂还能显著提高小白菜的维生素C和可溶性糖含量，增强对N，P养分的吸收。
- Concentrations of Pb, Zn, Cu, Cr, Ni, Mn, S, N and P in the soil were determined with the XRF method and values of pH and TOC were measured. 利用X射线荧光光谱法(XRF)对某城市工业区周围的土壤环境进行了研究。
- The N and P contents were as follow: Oasis > transitional zone > hungriness, and the K content was as follow: Hungriness > transitional zone > oasis. N、P含量：绿洲＞过渡带＞荒漠；而由于盐渍化的影响K含量：荒漠＞过渡带＞绿洲。
- Available N and P have inverse dynamics in that while available N decreases, available P increases, except for Phragmites communis Trin. 根际土有效态养分的变化则与全态相反，6种植物的根际土有效氮含量均显著低于非根际土，除芦苇外，根际土有效磷含量均高于非根际土。
- The results were found as following: wetland with plants was superior to unplanted one in removing ability of both N and P. 结果表明:有植物床的脱氮除磷效果好于无植物床,复合床脱氮除磷效果最好,但芦苇床、姜花床、复合床之间的差异不显著;
- The matter reason of eutropher in water is because algae grow raplily in propriety temperature and illumination when nutriment of N and P is imported from the environment. 水体富营养化的主要原因是由于外界输入过量的氮磷营养物质,在适当的温度、光照下,藻类过量生长繁殖造成的。
