摘要：

随着人们对畜禽肉类需求的持续增加，畜禽养殖业迅猛发展，由此产生的畜禽养殖废水的污染问题日益严重。畜禽养殖废水中的有机物、氨氮、悬浮物等污染物浓度高，水质较为复杂，对人体健康和环境质量威胁较大。目前应用于畜禽养殖废水处理的工艺众多，不同组合工艺对养殖废水的处理效果不同。针对该类废水的水质特点，一般将物理、化学方法用于畜禽养殖废水的预处理及深度处理，主要采用生物法作为常规处理工艺。对适于处理畜禽养殖废水的好氧处理工艺、厌氧处理工艺进行了比较，分析了处理畜禽养殖废水的实际工程案例，以期对畜禽养殖废水处理工艺选型提供参考和技术支持。

Abstract:

As the demand for livestock and poultry meat continually increase, its breeding industry has developed rapidly. The pollution of livestock and poultry breeding wastewater is becoming increasingly serious. The livestock and poultry breeding wastewater has high concentration of organic matter, ammonia nitrogen, and suspended solid, and the water quality of which is relatively complex, so it poses a great threat to human and environment. At present, there were many processes used in the treatment of livestock and poultry breeding wastewater. Different combination processes had different treatment effects for the breeding wastewater. Combined with the characteristics of the wastewater, physical and chemical treatment methods were generally used for the pretreatment and advanced treatment of livestock and poultry breeding wastewater. The biological method was mainly used as the conventional treatment process. The aerobic and anaerobic treatment processes applicable to livestock and poultry breeding wastewater were compared, and the actual engineering case of the treatment of wastewater was analyzed. It is hoped to provide reference and technical support for the selection of livestock and poultry breeding wastewater treatment process.

Key words: livestock and poultry breeding wastewater, biological treatment, wastewater treatment
