• 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、添加吸附介质、添加磷吸附介质、湿地浸润线浸润线、浸润线动态浸润线运行。

  • 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%.

    添加量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含量培养残渣中的NDF含量;
