摘　　要：以SBR工艺为例，研究实际工程中添加原水对SBR处理猪场粪污水中氨氮效率的影响，结果发现：当超越的原水与厌氧出水混合后，其COD/氨氮比值在3-4范围，处理系统趋于稳定，废水的可生化性得到了提高，同时增强了硝化、反硝化作用，由于原水的高pH使得处理系统的碱度得到回补，提高了脱氮效果。By taking SBR technology as an example, the paper sees impact of adding primary water on ammonia-nitrogen efifciency in SBR treating piggery wastewater. The result shows that after mixture of primary water and anaerobic water, the ratio of COD/ammonia-nitrogen is under 3-4 range, treatment system goes to stabilization, the bio-chemistry of wastewater enhances and nitriifcation and denitriifcation increase. Due to the high pH of primary water, the alkalinity of treatment system is returned and de-nitrogen efifciency is increased.
