采用离子交换生物反应器(IEBR)处理猪场废水。采用电子束辐照技术对养猪场废水中的有机物和营养物质进行了处理。猪场废水中有机物的最佳增溶剂量为20kGy75kGy.碳水化合物、蛋白质和脂类主要是蛋白质和脂类，主要含有溶解的有机物。猪场废水中有机物的增溶受温度和剂量共同作用的影响。在室温(23.0℃)条件下，当辐照剂量为0kGy时，化学需氧量(COD)和氨氮的最大去除效率分别为74.4%和76.7%。低温(15.3℃)对氨氮的去除有显著影响。另一方面，磷的去除不是电子束照射或温度的函数，因为鸟粪石是缺氧条件下的主要去除机制之一。
Swine wastewater was treated using an ion exchange biological reactor (IEBR). Organic matter and nutrient in swine wastewater were pre-treated by electron beam irradiation. The optimal dose for solubilization of organic matter in swine wastewater ranged from 20kGy to 75kGy. The carbohydrates, proteins, and lipids were investigated as proteins and lipids mainly contained the solubilized organic matter. The solubilization of organic matter in swine wastewater was affected by the combination effects of temperature and dose. The maximum chemical oxygen demand (COD) and ammonia removal efficiencies were 74.4% and 76.7% at a dose of 0kGy under room temperatures (23.0°C). The removal of ammonia was significantly affected by low temperature (15.3°C). On the other hand, the removal of phosphorus was not a function of electron beam irradiation or temperature because struvite is one of the main removal mechanisms under anoxic conditions.
