The strategies include chemically enhanced settlement, pre-aeration, addition of N-adsorption media and P-adsorption media, high, middle and low water level and dynamic saturation line within the.
改进方法包括化学强化预处理、预曝气、添加氮吸附介质、添加磷吸附介质、湿地高浸润线、中浸润线、低浸润线和动态浸润线运行。
There was a significant increment(P<0.05)in BCP production and significant decreases(P<0.05) in NH3-N concentration and NDF content in the culture residue when the FOS addition level was over 0.60%.
当添加量在0.60%以上时,可以显著(P<0.05)提高培养液中的BCP含量,显著(P<0.05)降低培养液中的NH3-N含量和培养残渣中的NDF含量;
In addition, the accumulative quantity n, P and K in the soil soluble liquid decreased further when the concentration of PAM increased.
同时,不同浓度pam的试验结果发现,增加PAM浓度能使土壤淋溶液中n,p,K累积量进一步减少。
Results showed that soil microbial biomass C, N, P significantly decreased after addition of atrazine. As composed with control, microbial biomass C, N and P decreased averagely 13.5%, 10.1%, 20.0%.
研究结果表明,在整个培养过程中,仅加莠去津的土壤中微生物生物量碳、氮、磷的含量均显著降低,与对照相比,分别平均降低了13.5%,10.1%,20.0%。
