| 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。

| Abstract: | 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. |
