用掩埋、无害化处理池加微生物和畜禽养殖场有机废弃物处理机等3种无害化处理模式,对病害生猪及其产品进行无害化处理,研究处理前后猪繁殖与呼吸综合征病毒(蓝耳病病毒)、猪瘟病毒、猪伪狂犬病病毒、圆环病毒等4种生猪常见病毒的变化。结果表明,病害生猪及其产品经掩埋和无害化处理池加微生物处理30 d后,还能检测到猪繁殖与呼吸综合征病毒和猪瘟病毒核酸阳性;经畜禽养殖场有机废弃物处理机处理24 h后,4种生猪常见病毒检测都为核酸阴性,说明掩埋和无害化处理池处理方式仍然存在生物安全隐患,可造成严重的二次污染,而畜禽养殖场有机废弃物处理机处理方式生物安全等级更高,更安全。
With the buried, harmless treatment pond plus micro-organisms and livestock and poultry farms organic waste treatment machine and other three kinds of harmless treatment mode, the disease live pigs and their products harmless treatment, research before and after treatment of porcine reproductive and respiratory syndrome Virus (blue ear virus), classical swine fever virus, Pseudorabies virus, circovirus and other four kinds of pigs common virus changes. The results showed that the porcine reproductive and respiratory syndrome virus and classical swine fever virus positive were detected after the diseased pigs and their products were buried and detoxified for 30 days and treated with microorganisms for 30 days. After being treated with organic wastes Machine processing 24 h, the four kinds of live pig virus detection are negative for nucleic acid, indicating that the treatment of landfill and detoxification treatment tank there are still biological safety problems that can cause serious secondary pollution, and livestock and poultry farms organic waste treatment Machine approach Biosafety level higher and safer.
