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。
